Description

The present invention relates to a driving support system that supports vehicle driving by providing information regarding various traffic monitoring activities such as traffic enforcement and inspections.

BACKGROUND ART Conventionally, as a driving support system for supporting vehicle driving, in-vehicle devices such as radar detectors that issue an alarm when receiving radar waves for speed enforcement and call the driver's attention have been realized. Some of these in-vehicle devices have a GPS function to measure the current position of the vehicle and a database of GPS contents such as installation points of speed enforcement systems, and detect approaching specific GPS contents. There is also a device that notifies the driver of this (for example, see Patent Document 1).

The GPS content that the in-vehicle device notifies of the approach mentioned above includes installation points of speed enforcement systems and permanent points such as police stations, as well as traffic monitoring activities such as speed enforcement and alcohol checks conducted frequently by mobile orbis. There are temporary points etc. In-vehicle devices attempt to alert drivers to traffic safety by notifying them of approaching various GPS contents.

However, the conventional driving support system has the following problems. In other words, unlike permanent points where there is always a notification target, even if a temporary point is notified of the approach, it is unclear whether or not traffic monitoring activities are currently being conducted at that temporary point. There is a problem in that drivers must individually judge the degree of risk.

JP2007-248180A

The present invention has been made in view of the above-mentioned conventional problems, and is a system that supports driving by providing information regarding various traffic monitoring activities such as traffic enforcement and inspections, and provides driving support with enhanced real-time performance. This invention aims to provide a system.

One aspect of the present invention is capable of posting posting information including type information representing the type of traffic monitoring activity carried out to promote traffic safety and location information representing the monitoring position where the traffic monitoring activity is being performed. A posting terminal,
A server that generates and distributes distribution information including type information and location information related to traffic monitoring activities by integrating multiple pieces of posted information that share the same traffic monitoring activities from multiple posting terminals. a device;
A driving support information distribution system includes a notification terminal that acquires and reports distribution information distributed from a server device.

One aspect of the present invention is that posting information including type information representing the type of traffic monitoring activity carried out to promote traffic safety and position information representing a monitoring position can be posted; The present invention is provided in a posting terminal constituting the driving support information distribution system according to an aspect of the present invention.

One aspect of the present invention is capable of acquiring and reporting distribution information including type information of traffic monitoring activities carried out to promote traffic safety and location information of monitoring positions, and another aspect of the present invention The notification terminal constitutes the driving support information distribution system.

One aspect of the present invention is a program for causing a computer to execute,
Another aspect of the present invention is a server program for realizing the functions of a server device constituting the driving support information distribution system.

One aspect of the present invention is a program for causing a computer to execute,
Another aspect of the present invention is a posting program for realizing the functions of the posting terminal.

One aspect of the present invention is a program for causing a computer to execute,
Another aspect of the present invention is a notification program for realizing the functions of the notification terminal.

By using the posting terminal according to the present invention, posting information including type information representing the type of traffic monitoring activity carried out to promote traffic safety and position information representing the monitoring position can be generated, and posted information can be sent to the server device. It is possible to post by The server device generates distribution information including type information and location information regarding traffic monitoring activities by integrating a plurality of pieces of posted information that have a common traffic monitoring activity to be posted. The notification terminal can notify distribution information distributed from the server device.

The distribution information can be, for example, highly real-time information generated based on the posted information, but the accuracy of the posted information varies, and some information may be correct and some information may be incorrect. If multiple pieces of posted information whose authenticity is uncertain are distributed as is, confusion may arise on the notification terminal side as to which information to believe. In particular, if a notification terminal is installed in the vehicle or if a portable notification terminal is brought into the vehicle, for example, if such posted information is distributed as is while the driver is driving, it may interfere with driving. There is a risk that this may occur.

On the other hand, the distribution information in the present invention may be information whose accuracy is increased by, for example, integrating a plurality of pieces of posted information. This distribution information, for example, has both real-time performance based on posted information and accuracy improved by information integration. Distribution information that is both real-time and accurate can be useful information for drivers.

As described above, the present invention is a system that supports driving by providing information regarding traffic monitoring activities such as traffic enforcement and inspections, and is an invention useful for realizing a driving support system with improved real-time performance. .

Traffic monitoring activities that are subject to posted information in the present invention include traffic enforcement such as speed enforcement, parking prohibition enforcement, and seat belt enforcement, and inspections such as drunkenness inspections and seat belt inspections.
The server device in the present invention may have both a function of receiving the posted information and a function of transmitting the distributed information, or a server that receives the posted information and a server that receives the distributed information. The server may be connected to the server via a dedicated line, private communication line, public communication line, or the like.

A server device in a driving support system according to a preferred aspect of the present invention is configured to post a plurality of pieces of posted information whose posting times are within a predetermined time and whose monitoring positions are within a predetermined range at the same time. It will be treated as posted information for traffic monitoring activities.

The time regarding posting of the posted information may be a time when the posted information is generated, a time when the posted information is posted, a time when a traffic monitoring activity related to the posted information is witnessed, or the like. The same traffic monitoring activity can be carried out by combining the temporal proximity that the time related to the posting is within a predetermined time and the locational proximity that the monitoring position is within a predetermined range. Target posted information can be extracted with high certainty, and highly accurate distribution information can be generated. The time when the posted information was generated and the time when the target traffic monitoring activity was witnessed need to be specified on the posting terminal side. Regarding the posted time, the posting terminal may specify the time when the posted information was sent, or the server device may specify the time when the posted information was received. When using the time specified on the posting terminal side on the server device side, it is preferable to include time information representing that time in the posting information.

The positional information representing the monitoring position in the driving system of a preferred embodiment of the present invention is information that can specify the direction of movement of the vehicle targeted by the traffic monitoring activity, in addition to the monitoring position where the traffic monitoring activity is being performed. be.
Except for one-way roads, roads that allow vehicles to travel in both opposite directions are common. Among the traffic monitoring activities carried out on roads, there are those that target only one direction of travel, such as road speed enforcement and inspections. If the distributed information can specify the direction of travel targeted by the traffic monitoring activity, it will be more useful for drivers driving on the road where the traffic monitoring activity is being performed. This is because the importance of the distributed information differs depending on whether the driver is traveling in the direction targeted by the traffic monitoring activity or the driver is traveling in the opposite direction. be.

The server device in the driving support system according to a preferred aspect of the present invention evaluates accuracy, which is a degree of certainty of the posted information, and also responds to the accuracy when integrating a plurality of posted information to generate the distribution information. to change the handling of each posted information.
Examples of how posted information is handled depending on accuracy are as follows. For example, the distribution information is generated using only posted information with a certain accuracy or higher. For example, for posted information that does not meet a certain level of accuracy, when multiple pieces of similar posted information are posted, it is handled as one piece of posted information. For example, posts of the same type within a radius of 100 meters are counted as one post.

The server device in the driving support system according to a preferred aspect of the present invention evaluates the accuracy of the corresponding posted information depending on whether the poster of the posted information is an identifiable person and the posting record of the poster. do.
Generally, it can be estimated that information posted by a specific person is more accurate than information posted by an unspecified person. It is also a good idea to convert achievements such as the number of times correct posted information has been posted for a specific poster into points, and use those points when evaluating the accuracy of posted information by that specific poster.

The posting terminal in the driving line-of-sight system according to a preferred aspect of the present invention includes a dedicated device in which the posted information posting function is pre-installed, and various application programs including an application program for incorporating the posted information posting function. There is a general-purpose machine that the user can select and install.
The server device evaluates the accuracy of the posted information depending on whether the posted information is posted from a dedicated machine or from a general-purpose machine.

Dedicated machines and general-purpose machines have different installation costs on the user side to use the posting function and expectations regarding the distributed information. For example, if the application program for a general-purpose machine is free software, there is a possibility that a user who is not very interested in the distribution information may post it as a prank. On the other hand, considering that they have purchased a dedicated machine, it can be assumed that the poster from the dedicated machine has expectations for the distribution information. For this reason, for example, when the level of detail and quality of the posted information itself is almost the same, it is better to evaluate the accuracy of information posted by the dedicated device more highly than the information posted by the general-purpose device. good.

The server device in the driving support system according to a preferred aspect of the present invention evaluates the accuracy of the posted information with reference to information regarding the implementation status of past traffic monitoring activities.
For example, if posted information regarding speed enforcement is posted at a location where speed enforcement is frequently carried out by mobile orbis, the accuracy of the posted information can be highly evaluated. On the other hand, if posted information regarding speed enforcement is posted for a location where speed enforcement has never been carried out by Mobile Orbis, the accuracy of the posted information will be evaluated as low, while similar posted information It is also a good idea to reevaluate the accuracy of the first posted information when it is posted twice.
The information regarding the implementation status of past traffic monitoring activities may be, for example, the implementation history of past traffic monitoring activities, or may be existing traffic information stored in advance regarding traffic monitoring activities. In particular, existing traffic information already accumulated by in-vehicle devices such as radar detectors without relying on posted information may be used as information regarding the implementation status of past traffic monitoring activities. Further, information obtained by adding past posted information to the existing traffic information that has already been accumulated may be used as "information regarding the implementation status of past traffic monitoring activities."

In the server device in the driving system according to a preferred aspect of the present invention, the posted information is handled depending on whether the posting of the posted information is received before or after distribution of the distributed information regarding the corresponding traffic monitoring activity. are different.
Before distribution, for any poster, the traffic monitoring activity to be posted suddenly appears, and it is necessary to determine its type etc. in a short period of time until it passes. There is a tendency for operations such as registration of points for traffic monitoring activities to be performed after the vehicle has passed the point, and there is a possibility that the point actually registered may be shifted further forward in the direction of travel than the actual point. On the other hand, if it is after the distribution, it is known in advance that traffic monitoring activities of the type related to the distributed information are being carried out, so it is possible to check whether the type of traffic monitoring activities actually being carried out is as per the distributed information. There is a tendency for the accuracy of the judgment to be higher. In addition, since the user approaches the location with a high level of interest in whether traffic monitoring activities are actually being conducted at the location associated with the distributed information, the registered location is likely to be exactly the same as the actual location. . Alternatively, if the poster is quick, there is a possibility that the poster may be shifted to the front side of the actual location. If the posted information after the distribution information is handled in consideration of such circumstances, the accuracy of the distribution information including the positional accuracy can be improved.

The server device in the driving support system according to a preferred aspect of the present invention determines whether or not to distribute the distribution information and the distribution time for continuing distribution, depending on the type of traffic monitoring activity.
For example, traffic monitoring activities such as speed enforcement, such as mobile orbis, generally have a known duration and do not continue for 24 hours. It is preferable to determine the distribution time of distribution information based on such knowledge.
On the other hand, information regarding fixed speed enforcement systems, N systems, etc. tends to require near 100% accuracy rather than real-time performance. Therefore, regarding posted information for fixed speed enforcement systems, N systems, etc., rather than immediately distributing the information upon receipt, the system operator's staff will go to the site and visually check the information, and then post the information. It is also a good idea to provide the information to the user as verified information.

The posting terminal in the driving support system according to a preferred aspect of the present invention is capable of posting cancellation information indicating that the traffic monitoring activity corresponding to the distribution information is not being carried out,
The server device evaluates the accuracy of the posted cancellation information, and determines whether to end the distribution of the corresponding distribution information according to the accuracy.
If the posting of the cancellation information is accepted, distribution can be completed as soon as possible after the corresponding traffic monitoring activity is completed. It is possible to suppress the situation in which the corresponding distribution information continues to be distributed even though the target traffic monitoring activity is not being performed in as short a time as possible. Further, the cancellation information is also useful for quickly canceling distribution of erroneous distribution information based on false posted information, or for giving a negative evaluation to the poster of false posted information.

In a case where the server device in the driving support system according to a preferred aspect of the present invention receives the posting of the cancellation information and then distributes the distribution information regarding the corresponding traffic monitoring activity, the server device sends a notification that the cancellation information has been posted. information will be included in the distribution information.
On the user side, when determining the accuracy of the distribution information, the user can take into account whether or not the cancellation information has been posted. The fact that corresponding traffic monitoring activities are not carried out is the biggest factor that undermines users' confidence in the distributed information. When distributing distribution information, if you also notify that cancellation information has been posted, you can minimize the damage to users' confidence in the distribution information even if corresponding traffic monitoring activities are not carried out. can be suppressed close to . Note that the information indicating that cancellation information has been posted may be, for example, information indicating whether or not cancellation information has been posted in the integrated posted information. In particular, it is preferable that the information indicates the number of posts of cancellation information. For example, it is preferable to distribute the number of posts of integrated post information and the number of posts of cancellation information among the number of posts.

A posting terminal according to a preferred aspect of the present invention includes means for generating posted information with different degrees of detail of the type information depending on the user's knowledge level regarding traffic monitoring activities.
For example, if the target traffic monitoring activity is speed enforcement, the types include mouse traps, mobile orbis, tracking, etc. Furthermore, for example, in the case of mobile Orbis, there are types such as radar type, stealth type, and phototube type. Users who have a deep interest in traffic monitoring activities such as speed enforcement and who can recognize the type of equipment or devices at a glance can post detailed information. On the other hand, for users who are able to recognize that this is a traffic monitoring activity related to speeding violations, but lack knowledge about speed measurement, requesting detailed information when posting may make it difficult to post and may discourage them from posting. expensive. Therefore, if users who have knowledge about traffic monitoring activities can generate detailed posted information, while users who do not have such knowledge can simply post detailed posted information such as speed enforcement, it would be possible to increase the number of posts by a variety of users. can be promoted. If the amount of posted information that serves as an information source increases, the real-time nature and accuracy of distributed information can be improved.

A posting terminal according to a preferred aspect of the present invention is capable of acquiring a current location, and also combines location information based on the acquired current location with the type information generated by an operation on the user's side to generate the posted information. generate.
In this case, the accuracy of the location information included in the posted information can be improved. Examples of configurations that can acquire the current location include a configuration that includes a GPS positioning function, a configuration that acquires current location information from an external terminal that has a GPS function, and the like.

A posting terminal according to a preferred aspect of the present invention includes a first terminal that can generate the posted information in response to an operation by a user, and a system that acquires the posted information from the first terminal and directs it to the server device. and a second terminal for transmitting data.
The first terminal is a terminal capable of acquiring the current location and displaying a code image recording the posted information,
It is preferable that the second terminal is a terminal capable of photographing a code image displayed by the first terminal and reading recorded posted information.
As the second terminal, a mobile terminal such as a smartphone (multifunctional mobile terminal) equipped with a camera function or a game machine equipped with a camera function and a communication function can be used. On the first terminal side, it is sufficient to simply display the code image in which the posted information is recorded. Such a first terminal can be fully realized not only by a display screen of about 3 to 4 inches, but also by the hardware configuration of an existing radar detector equipped with a GPS function.

A posting terminal according to a preferred aspect of the present invention is capable of displaying a map of a predetermined area including a point of interest, and is also capable of registering the point of interest as a specific point by operation on the user side,
The posted information is generated by associating the type of traffic monitoring activity selected by the user's operation with the position information representing a specific point registered in advance.
Specific points can be registered with high location accuracy on the displayed map. Posted information generated through such registration of specific points becomes highly accurate information with high positional accuracy.

A posting terminal according to a preferred aspect of the present invention is capable of acquiring a current location, and sets the current location as the point of interest.
In this case, if you register the specific point when you pass the point of traffic monitoring activity, that is, when your current location is located in the immediate vicinity of that point, you can easily and easily locate the point of traffic monitoring activity. Can be registered with high accuracy.

A notification terminal according to a preferred aspect of the present invention is capable of acquiring the current location and current time, and selects which of the acquired distribution information to broadcast according to the current location and current time.
In this case, appropriate distribution information can be notified according to the driving situation. For example, even if the user is far away from his or her current location and is not sure whether or not he or she will be heading to a location where the user is notified of distributed information about traffic monitoring activities, the information will be of little value to the user. On the other hand, distribution information regarding traffic monitoring activities being carried out in the vicinity of the user's current location is information of high value to the user, and is therefore preferably broadcast. Furthermore, if the vehicle is equipped with a navigation function, it is preferable to notify traffic monitoring activities at points on the route calculated by the route calculation function at an early stage when the distance is long.

The distribution information acquired by the notification terminal according to a preferred aspect of the present invention includes accuracy information indicating the accuracy of the distribution information,
The notification mode is changed depending on the accuracy of the acquired distribution information.
By changing the notification mode according to the accuracy of the distribution information, the user receiving the notification can judge the accuracy of the distribution information and take action. If traffic monitoring activities corresponding to the distributed information are not actually carried out, there is a risk that users' confidence in the distributed information will be significantly damaged, but if the user is also informed that the accuracy is low, the above can be avoided. damage to the sense of trust can be suppressed.

In the notification terminal according to a preferred aspect of the present invention, the relationship between the notification mode of the distribution information and the accuracy of the distribution information can be set by a user's operation.
While there are users who do not want to be notified of distribution information whose authenticity is uncertain, there are also users who wish to receive notification of all distribution information, regardless of its authenticity, and then make their own decisions. By configuring the system so that the distribution information to be notified can be selected according to the user's operation as described above, it becomes possible to appropriately notify distribution information to various users.

A notification terminal according to a preferred aspect of the present invention is capable of acquiring vehicle information representing the status of a vehicle to which it is attached, and changes the notification mode of distribution information according to the acquired vehicle information.
A notification terminal according to a preferred aspect of the present invention is capable of acquiring speed as the vehicle information, and changes the notification mode of distribution information regarding speed enforcement according to the acquired speed.
For example, when approaching a speed enforcement traffic monitoring activity point, if a vehicle is moving at a high speed, a notification will be provided to the driver to reduce the speed, such as by outputting a voice notification of the corresponding distribution information or by emitting a warning sound. It is good to do. On the other hand, if a similar notification is made when the speed is low due to traffic congestion, etc., there is a risk that drivers who cannot drive at all speeds will become irritated. In such a state, it is preferable to refrain from broadcasting the distribution information in response to the approach.

A notification terminal according to a preferred aspect of the present invention is capable of notifying the distribution information, and is also capable of notifying existing traffic information stored in advance regarding traffic monitoring activities.
The notification of the regulated traffic information is suitable for notification of traffic monitoring activities such as fixed speed enforcement. On the other hand, the notification of the distribution information is suitable for notification of traffic monitoring activities that require real-time performance, such as patrols by mobile Orbis, inspections, and police cars. By combining the two, it is possible to provide detailed support for the safe driving of the user, the driver.

A notification terminal according to a preferred aspect of the present invention is capable of acquiring a current location and can also notify information regarding traffic monitoring activities carried out within a predetermined area based on the current location,
When reporting information regarding traffic monitoring activities, the notification is made so that the user can distinguish whether the notification is based on the distributed information or the existing traffic information.
The distribution information is superior in real-time performance compared to the traffic regulation information, but is inferior in accuracy. When broadcasting the distribution information, if the distribution information is broadcast separately from the traffic regulation information, the user can determine the effective use of the distribution information in consideration of the above-mentioned characteristics.

A notification terminal according to a preferred embodiment of the present invention is integrated with a posting terminal according to another embodiment of the present invention.
In this case, it is convenient for the user because it becomes possible to post posted information, view distributed information, etc. using one terminal.

Embodiments of the present invention will be specifically described using the following examples.
(Example 1)
This example is an example related to a driving support system that distributes posted target information (distribution information) based on posted information. The contents will be explained with reference to FIGS. 1 to 24.
As shown in FIG. 1, the driving support system 1 of this example includes a posting server (server device) 11, a member management server (My Jupiter server) 12, a mobile terminal 2 having functions as a posting terminal and a notification terminal, etc. There is. Reference numeral 101A in FIG. 1 indicates the configuration of the posting terminal of this example, and reference numeral 101B indicates the configuration of the notification terminal of this example. Note that 102A and 102B indicate the configuration of a posting terminal or a notification terminal described in the second embodiment. Note that instead of this example, the posting server 11 and the member management server 12 may be integrated, or may be communicably connected via a dedicated line. The posting server 11 and the member management server 12 may be installed at the same location, or may be installed at different locations.

(Member management server)
The member management server 12, as shown in FIGS. 1 and 2, is a server device that manages members registered in the driving support system 1 of this example. The member management server 12 is equipped with a control board (control unit) on which a CPU for performing arithmetic processing, a ROM, a RAM, etc. as storage elements are mounted, a hard disk drive (HDD), etc., and a LAN port as an external interface. Equipped with communication ports such as The member management server 12 is connected to a public communication line via a communication port, and is capable of communicating information with the posting server 11.

A user management database 121 for managing members is provided in a storage area of the hard disk drive that is accessible from the control unit. The user management database 121 includes a member ID (My Yupitel ID) which is identification information, a login password, a poster ID which is identification information at the time of posting, user personal information, and information on points personally registered by the member (My Yupitel Points). ) etc. are stored and managed for each member. The member management server 12 of this example having the user management database 121 has a function as an authentication means for authenticating the member ID inquired from the posting server 11.

(posting server)
The posting server 11 is a server device that distributes posting target information that integrates posted information. This posting server 11 is equipped with a control board (control unit) on which a CPU for performing arithmetic processing, ROM, RAM, etc. as storage elements are mounted, a hard disk drive (HDD), etc., and a LAN port etc. as an external interface. Equipped with communication ports. The posting server 11 is connected to a public communication line via a communication port, and is capable of information communication with the posting server 11, the mobile terminal 2, and the like.

The storage area of the hard disk drive accessible from the control unit side includes a GPS target information database 111 that stores information regarding traffic monitoring activities, and a user status database 113 that manages posted evaluations for each member.
The storage area of the GPS target information database 111 includes a ready-made GPS area that stores ready-made traffic information, which is information about traffic monitoring activities that have been confirmed by the system, as well as a post area that temporarily stores posted information for each traffic monitoring activity. area, a distribution area for storing posted target information to be distributed, and a new information area for storing past posted target information for which distribution has been completed. The posted target information in the new information area becomes a candidate for existing traffic information to be newly added to the existing GPS area. The GPS target information database 111 may be formed using a single storage means such as a hard disk, or may be formed using a plurality of storage means such as a hard disk or flash ROM.

Existing traffic information for existing GPS areas is based on the location and area of installed traffic monitoring facilities such as Orbis, past traffic enforcement activities such as seatbelt enforcement and alcohol checks, and information such as the frequency of accidents. This is driving support information (POI data) that combines position information representing.
The posted information in the posting area is unprocessed information posted from the mobile terminal 2. Although details will be described later with reference to FIG. 17, in this posting area, posted information for each traffic monitoring activity is managed as a list in posting order.
The posted target information in the distribution area is information that is currently being distributed by integrating multiple pieces of posted information that share a common traffic monitoring activity.
The posted target information in the latest information area is past posted target information whose distribution has ended. This posted target information may be newly registered as existing traffic information after confirmation by the system administrator. For example, if posted information related to the unregistered N system (vehicle number reading system) is stored as existing traffic information, the system staff will visually check it on site and then register it as a new one in the existing traffic information system. Operation is possible. For example, if posted information or posted target information about unregistered traffic inspections is frequently recorded as existing traffic information, the system administrator can consider registering it as existing traffic information depending on the frequency.

As shown in Figure 3, the post evaluations stored in the user status database 113 include the total number of posts, the number of correct posts (number of correct posts), the number of incorrect posts, the ratio of correct posts among all posts (correct post rate), and the overall evaluation. It includes each evaluation item. The points of the comprehensive evaluation are points given as shown in FIG. 4 according to the number of correct posts and the correct post rate. In the user status database 113, data on each evaluation item is managed for each poster (member). Note that for members who have been prohibited from posting based on past posting results, a posting prohibition flag is set in the comprehensive evaluation data area. In this example, the overall evaluation points are treated as the accuracy of information posted by the poster.

The posting server 11 of this example realizes the following functions by causing the CPU to execute a server program, which is a computer program installed in advance.
(1) Posting receiving means A means for receiving posted information from the mobile terminal 2 etc. via a public communication line.
(2) Posting permission means: means for determining whether or not to permit acceptance of received posted information. The posting permission means uses the member ID included in the posted information to refer to the user status database 113 (FIG. 2) and determines whether permission is granted. Information posted by members with posting prohibition flags will be refused, and other posted information will be accepted.
(3) Sorting means Means for sorting the received posted information by traffic monitoring activity and storing it in the posting area of the GPS target information database 111 (FIG. 2). The sorting methods are based on the locational proximity of the posted location (the monitoring location or monitoring area of traffic monitoring activities), the temporal proximity with respect to the time when the location was recorded, and the commonality of the types of traffic monitoring activities. The submitted information is sorted based on three conditions.
(4) Posting target information generation means Means for generating posting target information by integrating multiple pieces of posted information classified as having a common traffic monitoring activity. The generated posted target information is stored in the distribution area of the GPS target information database 111 (FIG. 2).
(5) Distribution means A means of distributing posting target information. The distribution means distributes traffic support information to members registered on the driving support system 1 side who wish to receive the distribution and who have a terminal device that can be connected directly or indirectly to a public communication line. do.

Note that instead of the posting server 11 in this example, which has the functions of accepting posted information, generating posting target information, and distributing posting target information, each function may be configured with a separate server. good. Servers having these functions individually need only be connected in a communicable state, and may be installed at the same location, but may also be installed at different locations.

(Mobile device)
The mobile terminal 2 of this example is a palm-sized flat smartphone (multifunctional mobile phone), as shown in FIGS. 5 and 6. Most of the front surface is occupied by a touch panel 21 in which a touch sensor sheet 211 is laminated on a display screen of a liquid crystal display section 212 (FIG. 8), and a home button 2H is used to display a home screen (not shown) on the touch panel 21. is only placed beside the touch panel 21. A lens hole 220 is provided on the back side of the mobile terminal 2 and is fixed to a camera board 22 (FIG. 8) that constitutes an imaging means. Although not shown in FIGS. 5 and 6, the power button 200 (FIG. 8) and the like are arranged on the outer peripheral side surface. In the driving support system 1 of this example, the preferred usage mode of the mobile terminal 2 is in a state where it is fixed to a vehicle dashboard or the like using an in-vehicle holder 19 or the like, as shown in FIG.

As shown in FIG. 8, the portable terminal 2 houses a control board on which an electric circuit forming the control section 20 is formed. The control unit 20 includes a camera board 22 on which CMOS elements, lenses, etc. are mounted, an amplifier board 23 that drives a speaker 230, a power button 200, a touch sensor sheet 211, a liquid crystal display unit 212, and a wireless transceiver 241. , a GPS receiver 242, a clock section 243, and the like are electrically connected.

The wireless transceiver 241 is a means for performing wireless communication in a predetermined frequency band. The wireless transceiver 241 of this example is capable of transmitting and receiving digital voice data obtained by digitizing telephone voice by circuit switching, and can also transmit and receive digital data such as posting information, posting target information, application programs, map data, etc. by packet communication. It is possible.

The GPS receiver 242 is a receiver that receives GPS signals from GPS satellites and outputs the current time, location information (latitude and longitude) of the current location, current speed, altitude, etc. The GPS receiver 242 is built into the main body of the mobile terminal 2 so as to be located above the center on the back side when in the vertical position as shown in FIG.

As shown in FIG. 8, the control unit 20 includes a CPU 201, a ROM 202, a flash ROM 203, and a RAM 204 that are storage elements, an I/O unit 205 that serves as an input/output interface, and the like. The ROM 202 stores various control programs including BIOS and the like. The flash ROM 203 stores various installed processing programs. The RAM 204 is a readable and writable storage element that is also used as a work area for the CPU 201 and for temporary writing.

By causing the CPU 201 to execute a program read from the ROM 202 or flash ROM 203, the control unit 20 provides not only telephone functions and data communication functions, but also a map display function that displays a map on the touch panel 21, and a posted information generation function that generates posted information. , a posting function for posting posted information, a warning function for traffic monitoring activities, etc. Each means for realizing these functions is formed in the control section 20.

The posting information generation function and posting function are incorporated by installing dedicated posting software. This posting software can be downloaded from the application server 15 on the premise of member registration on the driving support system 1 side (see FIG. 1). The posting software installed on the mobile terminal 2 includes encrypted data of the member ID and login password given to registered members. In order to start the posting software on the mobile terminal 2, you are required to enter the member ID and password given at the time of registration, and the condition for starting the posting software is that the information incorporated as encrypted data and the input information completely match. It becomes. In the driving support system 1 of this example, posting by unspecified persons other than members is avoided by requesting input of a member ID, etc. when starting the posting software.

The storage area of the flash ROM 203 is provided with a map database storing map data and a GPS target information database 111 storing GPS target information related to traffic monitoring activities. Examples of the GPS target information include existing traffic information such as N system installation information, posted target information distributed from a posting server, and the like.
Map data (MAP data) can be downloaded from a server that provides maps (see Figure 1). In this example, one of the application servers 15 of the posting software also serves as a map server.
Existing traffic information is stored in the GPS target information database 111 when the posting software is installed.
The posted target information is stored in the GPS target information when it is delivered, and is deleted after a predetermined period of time has passed.

The storage area of the flash ROM 203 is further provided with a posting pin storage area that stores information regarding traffic monitoring activities to be posted. The posted pin storage area can store up to four pieces of posted pin information related to traffic monitoring activities to be posted. The posted pin information is composed of the following information.
・Time information indicating the pin registration time when the posting pin was registered on the map (registration time of the posting target location) ・Location information (latitude and longitude, (Address, enforcement direction that is a 180-degree reversal of the vehicle's direction)
・Activity content information indicating the type, implementation mode, method, etc. of traffic monitoring activities (including type information)

The basic operation of the mobile terminal 2 of this example will be explained.
On the home screen (not shown) of the mobile terminal 2 in which the posting software is installed, an icon of the posting software (not shown) is displayed. When the control unit 20 of the mobile terminal 2 receives a touch operation on this icon, it displays the startup splash screen 21A on the touch panel 21, and then displays the login screen 21B, as shown in FIG. The login screen 21B is a screen that requests input of the member ID and login password registered on the driving support system 1 side.

The control unit 20 checks whether the member ID and login password input via the login screen 21B completely match the member ID and login password recorded in the posting software. When the control unit 20 is able to verify the member ID and login password, it switches the display on the touch panel 21 to the home screen 21C. This home screen 21C is a screen on which a surrounding map of the point of interest is displayed, and at the bottom of the screen, in addition to a pin setting button 251 and a setting button 252, there is also a WEB page for guiding you to the product site of the radar detector on the Internet. A guidance button 255 is arranged.

On the home screen 21C, the map display area is set so that the point of interest coincides with a predetermined position at the bottom center of the screen. The current position acquired by the GPS receiver is usually set as the point of interest. The control unit 20 sets the current position as the point of interest and displays the surrounding map on the home screen 21C unless a user operation to change the point of interest is input. While the vehicle is running, the display area of the map is changed at any time so that the own vehicle mark 250 representing the current position is located at a predetermined position at the lower center of the screen.
A setting button 252 with a "spanner" mark at the bottom right of the home screen 21C is an operation button for displaying the various setting screens 21D shown in FIG. 10. On the various settings screen 21D, settings such as the warning display mode, audio output mode, warning order setting, map display mode, etc. can be changed. A pin setting button 251 to the left of the setting button 252 is an operation button for registering a posted pin at a point of interest (usually the current position).
The home screen 21C is a basic screen that is displayed when the posted pin 262 is unregistered. On the other hand, if one or more posting pins are registered, the standby/posting screen 21E (FIG. 11) shown in FIG. 11 to which a posting button 253 for starting posting is added becomes the basic screen.

As shown in FIGS. 9 and 11, when displaying the home screen 21C or the standby/post screen 21E, the control unit 20 refers to the GPS target information database 111 and acquires existing traffic information or posted target information around the current location. . The control unit 20 scrolls and displays this information in the information display field 254, and displays a target icon 261 at the corresponding position on the map. The information display field 254 displays text information that warns of traffic monitoring activities near the current location. Note that among the target icons 261 illustrated in FIG. 11, a circled H indicates the new H system, a circled N indicates the N system, and a circled P indicates parking. Note that the display of these existing traffic information or posted target information will be explained in detail later.

Next, the operation of the driving support system of this example configured as above will be explained. Below, (1) posting operation of posted information by the mobile terminal 2 (posting terminal 101A in FIG. 1), (2) generation and distribution operation of posting target information by the posting server 11 that received the posted information, (3) posting target The alarm operation by the mobile terminal 2 (notification terminal 101B in FIG. 1) that receives the information distribution will be explained in this order.

(1) Posting operation of posted information by mobile terminal 2 The posting operation in a situation where the vehicle is running and a map around the current location is displayed on the home screen 21C or the standby/posting screen 21E will be described.
When users of the posting software witness traffic monitoring activities such as mobile Orbis, they can register their current location by touching the pin setting button 251 (Fig. 11) on the home screen 21C or the standby/posting screen 21E. be. The control unit 20 that detects the touch operation on the pin setting button 251 first obtains the time, latitude and longitude of the current position, and heading direction from the GPS receiver 242 and temporarily stores them.

The control unit 20 checks an empty area in the posted pin storage area and stores new posted pin information in the empty area. When posting pins 262 are registered, time information and position information, which are part of the posting pin information, are stored based on the temporarily stored time, latitude and longitude, and heading. The time information is the temporarily stored pin registration time. The position information includes the temporarily stored latitude and longitude, the corresponding address, and the enforcement direction obtained by reversing the temporarily stored traveling direction by 180 degrees. Note that if there is no free space in the posted pin storage area, the temporally earliest posted pin 262 will be deleted, and the corresponding posted pin information stored in the posted pin storage area will be deleted, leaving the vacant area. Secured. On the map displayed on the standby/post screen 21E, a posting pin 262 is set at a position corresponding to the position information of the posting pin information. Note that up to four posting pins 262 can be set, and numbers are assigned in order from the earliest registration time to the posting pin 262. The posted pin information in the posted pin storage area is stored in a state in which the pin numbers of the corresponding posted pins are associated with each other.

When the control unit 20 detects a touch operation on the post button 253, it displays on the touch panel 21 a pin list screen 21F (FIG. 12) that displays a list of posted pin information stored in the posted pin storage area. In addition to four pin selection buttons 256 for each posted pin, a return button 257 is arranged on the pin list screen 21F. To the right of each pin selection button 256, corresponding posted pin information is displayed in text. This text display is a display of posted pin information excluding activity content information of traffic monitoring activities, and includes display of pin registration time, latitude and longitude, address, and enforcement direction. In this example, since the enforcement direction is set as essential information in the posted information, in FIG. 12, in addition to the unregistered pin button 256 No. 4, the pin button 3 256 whose bearing is undetermined cannot be operated. It becomes.

Note that direction measurement using the GPS function of the mobile terminal 2 in this example uses radio waves broadcast from multiple broadcasting stations such as GNSS space segments (artificial satellites such as GPS, SBAS, GLONAS, and COMPASS) or mobile terminal base stations. This is done by measuring the amount of Doppler shift or using a relative method with past positioning points. After the 1st Fix is completed (after the first positioning is completed), it is determined when the vehicle speed reaches 10 km/h or more. Thereafter, although the value of the measured azimuth changes as the vehicle travels, the azimuth measurement remains fixed until the power is turned off. Note that after the direction measurement is confirmed, the pin setting button 251 on the standby/posting screen 21E can be operated even if the current position is not measured, but since the current position cannot be acquired, the posting pin 262 is not set on the map. Displayed while searching (not shown). Thereafter, upon returning to the positioning state, the current position is acquired and the posting pin 262 is set.

The control unit 20 displays posting screens 21G to 21K ( 13 to 16) as appropriate to generate activity content information to be stored as posted pin information.
The posting screen 21G is a screen for selecting the type (category) of traffic monitoring activity. The posting screens 21H and 21I are screens for selecting implementation modes, methods, etc. of traffic monitoring activities. The posting screen 21J is a confirmation screen for generated posted information. The posting screen 21K is a display screen indicating that posting has been completed.
Here, the types of traffic monitoring activities are Orbis, N system, inspection, and enforcement. The implementation modes and methods of traffic monitoring activities vary depending on the type of traffic monitoring activity. For example, if it is an N system, there are no variations in implementation or method. On the other hand, regarding enforcement, there are variations such as mousetraps and mobile Orbis, and there are also variations of Mobile Orbis such as radar type and stealth type. Whether or not the posting screens 21H and 21I are displayed during the posting operation depends on the type of traffic enforcement activity and the like.

Among the posting screens 21G to 21K, the posting screens 21G, 21J, and 21K are screens that the user always passes through regardless of the type of target traffic monitoring activity. On the other hand, the posting screens 21H and 21I are screens that may not be used depending on the type of traffic monitoring activity. For example, as shown in FIG. 14, when the type of traffic monitoring activity is the N system (vehicle number reading system), the posting screens 21H and 21I are not displayed because there are no variations in implementation or method. On the other hand, as shown in FIG. 15, when the type of traffic monitoring activity is enforcement, the implementation mode and method are subdivided, so it is necessary to display the posting screens 21H and 21I to have the user input information.

During the process of passing through the posting screens 21G to 21I, the control unit 20 generates activity content information corresponding to the operation button selected by the user's operation, and stores it in the posting pin storage area as needed. The activity content information forming part of the posted pin information is finalized when the posting screen 21J is reached. This posting screen 21J includes a text display of the generated posted information, as well as a posting button 259 and a return button 257. When the touch operation of the post button 259 is detected, the control unit 20 reads the corresponding post pin information from the post pin storage area, adds the poster's membership information such as the member ID and registrant ID, and saves the post information. generate. The control unit 20 transmits the posted information generated in this way to the posting server 11, and when the transmission is completed, switches the display on the touch panel 21 to the posting screen 21K. This posting screen 21K is displayed for several seconds, and then the display ends upon returning to the home screen 21C or the standby/posting screen 21E.

Note that each of the posting screens 21H and 21I, excluding the posting screen 21G for selecting the implementation mode and method of traffic monitoring activities, is provided with a selection button 258 labeled "Other/Unknown." When this "Other/Unknown" selection button 258 is operated, the control unit 20 selects the activity content stored in the posted pin storage area without going through the sequence of the posting screen 21 illustrated in FIGS. 13 to 16. The information is confirmed and the posting screen 21J is immediately switched and displayed. In the mobile terminal 2 of this example with such specifications, for example, even if a user does not know the difference between Orbis (speeding violation) methods, the detailed level of ``Orbis is installed'' will be displayed depending on the user's level of knowledge. Posted information can be generated relatively easily. On the other hand, a user with a high level of knowledge who is familiar with the differences in the Orbis methods can generate posted information with a high level of detail by selecting one of the methods on the posting screen 21I.

Further, as shown in FIG. 15, if the type is enforcement, the posting screen 21I can be passed by selecting the "Other/Unknown" selection button 258 on the posting screen 21H. For users whose level of knowledge is not very high, having the posting screen 21 displayed one after another may feel tedious, while the above-mentioned specification in which a portion of the posting screen 21 is passed may be difficult for users who are not very knowledgeable. It is also effective for activating posting activities.

The posted information posted by the operation of the mobile terminal 2 as described above includes the following information, as shown in the text display on the posting screen 21J. Among these, time information and location information are information stored in the posting pin storage area when the posting pin 262 is registered, and activity content information is stored in the posting pin storage area in the process of passing through the posting screens 21G to 21I. This is stored information. The member information is added to the posted pin information read from the posted pin storage area when posting.
- Time information indicating pin registration time - Location information of the monitoring position where traffic monitoring activities are carried out (latitude/longitude, address, direction)
・Activity content information indicating the type, implementation mode, method, etc. of traffic monitoring activities ・Membership information of the poster such as member ID and registrant ID

(2) Posting target information generation and distribution operations by posting server 11 When posting information is received from mobile terminal 2, posting server 11 first requests authentication from member management server 12. The member management server 12 requested for authentication uses the member information received from the posting server 11 to refer to the user management database 121 (FIG. 2) and determines whether the corresponding member exists. When the corresponding member exists validly, the member management server 12 returns the poster ID of the member.

When the posting server 11 receives authentication from the member management server 12, it refers to the user status database 113 and checks whether there is a posting prohibition flag for the poster. The posting server 11 deletes posted information for which the posting prohibition flag is set without accepting it, while executing an acceptance process for posted information for which the posting prohibition flag is not set. In this reception process, first, the posted information is temporarily stored in association with the posted time (incoming call time), and sorted by traffic monitoring activity. In this sorting, the condition of commonality of type is that the type of traffic monitoring activity is common, the condition of locational proximity that it is located within a radius of 100 m (predetermined range), and the condition of proximity of the type of traffic monitoring activity is that the type of traffic monitoring activity is common. The posting area is searched for other posted information that satisfies the condition of temporal proximity that the posted information was posted within. When other posted information that satisfies all the conditions is found, the newly accepted posted information is classified as having the same traffic monitoring activity as the other posted information, and is accepted in order as shown in the posted information list in Figure 17. A sequential posting number is assigned and stored in the posting area. On the other hand, if past posted information that satisfies the conditions of commonality of type, proximity of location, and proximity of time is not stored in the posting area, the posting server 11 A new posted information list similar to that shown in FIG. 17 is generated using the newly received posted information as the starting point (posted number 001).

When adding new posted information to the posted information list in FIG. 17, the posting server 11 refers to the user status database 113 using the poster ID of the new posted information to inquire about the poster's posting evaluation. As described above with reference to FIG. 3, the posting evaluation items for each poster include the total number of posts, number of correct posts, number of incorrect posts, correct posting rate, and overall evaluation. When adding new posted information to the posted information list in the figure, the posting server 11 adds up the points of the poster's comprehensive evaluation (FIG. 3), calculates and stores cumulative points. As will be described in detail later, the accumulated points are used as an evaluation value of the accuracy of the posted target information based on the posted information. In this example, all posted information is recorded as shown in Figure 17, but instead, posted information whose overall evaluation points are below the reference point are recorded without being registered in the list shown in Figure 17. You can also delete it.

The information detail level in the posted information list in FIG. 17 is a value representing the degree of detail of the activity content information included in the posted information. In each of the posting screens 21H and I (FIGS. 13 to 16), the detailed level of posted information generated when a significant selection other than "Other" is made is 3, and only in one of the posting screens 21H and I. Posted information generated by making a significant selection has a detail level of 2, and posted information generated by making a significant selection only on the posting screen 21G has a detailed level of 1. Naturally, for the N system in which there is no distinction between implementations and methods and the posting screens 21H and 21I are not presented, the information detail level of all posted information is level 1. On the other hand, there are various types, implementations, and methods, and the detailed level of information such as a mousetrap on which the posting screens 21H and 21I are presented varies from detailed level 1 to 3 depending on the posted information.

Here, the conditions for temporal proximity and locational proximity, which are conditions for sorting newly received posted information, will be explained.
The temporal proximity condition is that the pin registration time of new posted information is included within a predetermined time based on the pin registration time of the preceding posted information. As shown in FIG. 18, this predetermined time is set to be a different time for each posted information, depending on the overall evaluation of the poster of the preceding posted information (FIG. 3) and the traffic volume at the monitoring position. The longer the predetermined time period is set for the posted information with higher overall evaluation points among the posted evaluations. Also, depending on whether the monitoring location is in an urban or rural area, whether it is on a main road or not, and the number of vehicles owned by the police station with jurisdiction to which the monitoring location belongs, the higher the traffic volume expected in advance, the shorter the predetermined time will be. The lower the traffic volume, the longer the time is set.

As shown in FIG. 18, for example, when second posted information that satisfies the above two conditions of locational proximity and type commonality is received after receiving the first posted information, the arrival time is If it is within the predetermined time set for the first posted information (the time indicated by the downward arrow in the figure), this second posted information is classified as having a common traffic monitoring activity. Further, for example, regarding the fifth posted information that satisfies the above two conditions after receiving the fourth posted information, the arrival time is after the predetermined time set in the fourth posted information has elapsed; , within the predetermined time set in the third posted information. Accordingly, like the fourth posted information, the fifth posted information is classified as having the same traffic monitoring activity as the third posted information.

The locational proximity condition is that the position according to the new posted information is included within a radius of 100 meters around the reference point. The position of this reference point changes from time to time, as shown in FIG. 19, when posted information is sorted one after another. Here, B1, B2, B3... represent each post information before distributing the corresponding post target information, and A1, A2, A3... represent each post information after distributing the corresponding post target information. Represents posted information. The number following A or B indicates the order in which they were posted. For example, the posted information B1 is the posted information that is the starting point of the first posting. A1 is posted information posted first after the corresponding posted target information is distributed. The vertical direction in the figure represents the change in time. The left and right direction represents the position on the road in the forward and backward direction where the traffic monitoring activity to be posted is performed. With respect to the direction of travel of the vehicle, the right side indicates the backward side, and the left side indicates the forward side.

When the posting server 11 receives the posted information B1 serving as the starting point, it first sets the corresponding monitoring position as the first reference point 1 (the point circled 1 in FIG. 19). After that, when new posted information B2 regarding traffic monitoring activities with a monitoring position within a radius of 100 m centered on this reference point 1 and a common type is received, the monitoring position of this posted information B2 and the reference point 1 and set as a new reference point 2. When we receive new posted information B3 regarding traffic monitoring activities that have a monitoring position within a radius of 100 m centered on this reference point 2 (point in circle 2) and have a common type, we can monitor this posted information B3. A position separated from the reference point 2 toward the monitoring position (B3) by a distance obtained by equally dividing the distance between the position (B3) and the reference point 2 into three is set as a new reference point 3 (the point in the circle 3). While reference point 2 is a point based on two posted information, the monitoring position (B3) is a point based on only one posted information, so the position of this reference point 3 is based on the idea of weighted average. An intermediate position is determined. In addition, if posted information B4 is grouped after this reference point 3 is set in response to the reception of posted information B3, the distance between the monitoring position (B4) of this posted information B4 and reference point 2 is set by 4. A position separated from the reference point 3 toward the monitoring position (B4) by an equal distance is set as a new reference point 3.

Note that the weighted average coefficient is different before and after the posting target information is distributed. Specifically, for the monitoring position of posted information before distribution, the coefficient of the above weighted average is set to 1, and for example, if the reference point is based on 4 pieces of posted information, the new monitoring position and reference point are It is shifted to the new monitoring position by a distance obtained by dividing the distance into 5 equal parts. On the other hand, regarding the monitoring position of posted information after distribution, the coefficient of the above weighted average is set to 2. For example, if the reference point is based on 6 posted information, the distance between the new monitoring position and the reference point is It is shifted to the new monitoring position by a distance twice as many as 8 equal parts.

The reason why posting target information is handled differently before and after distribution will be explained. Before distribution, for any poster, a traffic monitoring activity appears unexpectedly, and it is necessary to determine the type of traffic monitoring activity within a short period of time before passing. Therefore, there is a tendency for operations such as registering points for traffic monitoring activities to be performed after the point has been passed, and the posted target point that is actually registered is shifted further forward in the direction of travel (in the direction of passing) than the actual point. Probability is high. On the other hand, after distribution, it is known in advance that the type of traffic monitoring activity related to the posted target information is being carried out, so the type of traffic monitoring activity that is actually being carried out is as per the posted target information. There is a tendency for the accuracy of judgment as to whether or not it exists to be higher. In addition, since the person approaches the point with a high level of interest in whether traffic monitoring activities are actually being carried out at the point related to the posted target information, the registered point will be exactly the same as the actual point. easy. As mentioned above, if the coefficients of the weighted average when determining the reference point before and after distribution are different, and the coefficient of the monitoring position of post-distribution information is increased, high accuracy of the monitoring position can be expected for posts after distribution. The information can be quickly reflected in the position of the reference point, and the positional accuracy can be improved.

The posting server 11 integrates posted information and starts generating posted target information for distribution for traffic monitoring activities for which the accumulated points in the posted information list in FIG. 17 exceed a predetermined reference point. This posting target information includes the following information.
・Time information indicating the earliest pin registration time among the posted information ・Location information of the monitoring position where traffic monitoring activities are carried out (latitude and longitude, address, direction)
・Activity content information indicating the type, implementation mode, and method of traffic monitoring activity ・Accuracy information indicating the degree of certainty of posting target information

The location information in the posting target information includes the latitude and longitude of the average position of the most recent 10 posted information, the address corresponding to the latitude and longitude, and the average direction of the most recent 10 posted information. . Note that the reference point (FIG. 19) for determining locational proximity may be set to the latitude, longitude, and address in the location information included in the posted information.
In generating the activity content information of the posting target information, the posting server 11 refers to the posting evaluation for each poster (Fig. 3), and determines whether the overall evaluation score is 7 points or more and the correct posting rate is Select information posted by 70% or more posters. If the difference in the activity content information of the selected posted information is only in the level of detail, and there is no difference in implementation mode or method, the activity content information of the posted information with the highest level of detail will be posted as is. This is set in the activity information included in the target information. On the other hand, if there is a difference in implementation, method, etc., the activity content information determined by majority vote is included in the posting target information. If the decision cannot be made by majority vote, priority is given to activity content information by a poster who is detailed and has a high correct posting rate among the selected posted information.
The latest accumulated points are set as is in the accuracy information of the posting target information.

The posting server 11 of this example stores all the posting target information generated as described above in the new information area, and also distributes posting target information other than the installed Orbis and N systems using public communication lines. do. The posting server 11 stores posting target information regarding the installed Orbis and N systems without distributing it, and then outputs it in response to an output operation by a system administrator or the like. Posted target information, which is also newly installed information for the installed Orbis and N systems, is visually confirmed by the staff on the system side, and when it is visually confirmed, it is registered in the existing GPS area (GPS target information database 111 in FIG. 2). The existing traffic information registered in this way is distributed to users of radar detectors, etc. that warn of approaching GPS content such as Orbis and N system, and is then downloaded to the mobile terminal 2. Included in posting software.

(3) Alarm operation by mobile terminal 2 Next, an alarm by mobile terminal 2 will be explained. The mobile terminal 2 of this example is capable of issuing a warning using existing traffic information that is incorporated into the GPS target information database 111 when the posting software is installed, and posted target information that is stored in the GPS target information database 111 after being distributed. It is. Such a warning is executed while the home screen 21C (FIG. 9) or the standby/post screen 21E (FIG. 11) is displayed. On the home screen 21C or the standby/post screen 21E after receiving posted target information, as shown in FIG. 20, the target icon 261C for existing traffic information is displayed as a circular mark, and the target icon 261R for posted target information (distribution information) is displayed as a square mark. Displayed as a mark.

The rectangular target icon 261R of the posted target information is displayed in a color-coded manner according to the accuracy represented by the accuracy information included in the posted target information. Those with low accuracy are displayed in cool colors, and as the accuracy increases, the colors change to warm colors, and those with high accuracy are displayed in red. Note that instead of or in addition to this, the size of the rectangular mark may be changed depending on the accuracy of the posting target information.

When the control unit 20 of the mobile terminal 2 detects a touch operation on the rectangular target icon 261R, it displays a data display screen 21L that displays detailed data of posted target information, etc., as shown in FIG. On this data display screen 21L, in addition to detailed data of posting target information, accuracy, number of postings, share of highly rated posters, past results of similar traffic monitoring activities, and poster list are displayed. When the control unit 20 detects a touch operation on any poster in the poster list, the control unit 20 switches and displays the display screen (not shown) of the content posted by the poster and the points of the overall evaluation of the poster. . Note that when a circular target icon 261C corresponding to existing traffic information is touched, detailed information of the corresponding existing traffic information is displayed.

Furthermore, the mobile terminal 2 displaying the home screen 21C or the standby/posting screen 21E, as shown in FIGS. When approaching a GPS target, a warning is issued depending on its type. While displaying the home screen 21C or the standby/post screen 21E, the control unit 20 refers to the GPS target information database 111 and acquires existing traffic information or posted target information around the current location. The control unit 20 constantly calculates the distance from the current location with respect to the GPS target in the existing surrounding traffic information or posted target information, and detects the approach to the corresponding GPS target according to this distance.

FIG. 22 is an example of a warning when approaching an installation position (monitoring position) of the N system and a warning when approaching a seat belt enforcement area (monitoring area). The former is an example of a traffic monitoring activity alert that is carried out at a point rather than an area. The latter is an example of a warning for traffic monitoring activities carried out in the area.
When the standby/posting screen 21E is displayed and a point where it takes 340m to reach the installation position of the N system, the control unit 20 displays a text display such as "N system 340 m" in the information display field 254, and also displays a text display such as "N system 340 m" An illustration 265 representing the following is displayed as a pop-up on the screen.
When the vehicle reaches a point 340 meters before the seat belt enforcement area, the control unit 20 displays text such as "Seat belt enforcement 340 meters" in the information display field 254, and pops up a corresponding illustration 265 on the screen. . Further, when the vehicle is traveling within a seatbelt enforcement area, that is, the current position belongs to the area, the control unit 20 displays a text display such as "seatbelt enforcement" in the information display field 254. When the user passes through that area, that is, when the current position leaves the area, the character display in the information display field 254 is erased, and the original standby/post screen 21E is returned to the displayed state.

FIG. 23 is an example of a warning when approaching the installation location of Expressway Orbis. The timing at which the warning starts when the vehicle approaches the installation location of the Orbis on the expressway differs depending on whether or not the vehicle speed at that time exceeds the speed limit. If the speed limit is exceeded, the control unit 20 displays text such as "Expressway Orbis 2000m" in the information display field 254 when the vehicle reaches a point where it is 2000m away, as shown in the leftmost diagram in the figure. At the same time, the corresponding illustration 265 is displayed as a pop-up. In addition, the control unit 20 issues an audio warning such as "2 kilometers ahead, Loop Coil Orbis, Road XX."

On the other hand, when the speed is within the speed limit, the control unit 20 displays a text display such as "Expressway Orbis 1000m" in the information display column 254 when reaching the point where it takes 1000m, as shown in the center diagram of the figure. At the same time, the corresponding illustration 265 is displayed as a pop-up. Furthermore, an audio warning such as ``1 km ahead, ○○ road, radar type Orbis'' is executed. After that, when the camera reaches a point 500 meters before the vehicle, the speaker 230 outputs a voice saying, "The camera is on the right side."
Furthermore, when you reach a point just 300 meters away, an information display field 254 is displayed that displays text to that effect, as well as an audio warning such as "300 meters ahead, XX road, radar type Orbis. Traveling speed is 120 km." Execute.

Note that public enforcement information may also be added to the posting target information distributed by the posting server 11. In this case, public enforcement information and warnings as shown in FIG. 24 can be issued. The figure is an example in which a text displaying "Seatbelt enforcement week starts from August 1st" is scrolled and displayed in the information display column 254.

As described above, by using the mobile terminal 2 of this example, it is possible to generate posted information including type information representing the type of traffic monitoring activity carried out to promote traffic safety and position information representing the monitoring position. , can be posted to the posting server 11. The posting server 11 generates posting target information (distribution information) including type information and location information regarding the traffic monitoring activity by integrating a plurality of posted information having a common traffic monitoring activity to be posted. The other mobile terminals 2 can issue notifications, warnings, etc. using the posting target information from the posting server 11.

While the posted information from the mobile terminal 2 includes highly real-time information, the accuracy of the posted information varies, and some information may be correct and some information may be incorrect. If a plurality of posted information whose authenticity is uncertain is distributed as is, confusion may arise on the side of the mobile terminal 2 receiving the distribution as to which information to believe.
On the other hand, according to the posting server 11 of this example, posting target information with increased accuracy can be distributed by integrating a plurality of pieces of posted information. This posted target information is easy to use and useful information that is both real-time based on posted information and accuracy improved by information integration.

In particular, in this example, posted information to be integrated is sorted by determining three conditions: temporal proximity, commonality of types of traffic monitoring activities, and locational proximity. According to such sorting, posted information for a specific traffic monitoring activity can be extracted with high accuracy. Further, when the posted information classified in this way is integrated to generate posted target information, the accuracy of each posted information is evaluated, and posted information with high accuracy is selectively used. Since the posted target information is information generated by integrating highly accurate posted information, its accuracy is high. Furthermore, the accuracy of posted target information generated by integrating posted information that has been evaluated for accuracy is easy to evaluate, making it easier to manage on the side that delivers and on the side that receives distribution. On the distribution side, it is also good to selectively distribute posting target information depending on the accuracy. On the receiving side of the distribution of posted target information, it is also possible to selectively issue notifications or warnings depending on the accuracy.

As described above, the driving system 1 of this example is a system for supporting driving by distributing posted target information based on posted information regarding traffic monitoring activities such as traffic enforcement and inspections, This is an excellent system that combines real-time performance and accuracy (reliability).

It may be configured such that cancellation information indicating that the traffic monitoring activity related to the distributed posted target information is not being implemented can be generated as the posted information. For example, a cancel post button for sending cancellation information may be additionally placed on the data display screen 21L of FIG. 21 that is displayed by touching the rectangular target icon 261R (FIG. 20) on the standby/post screen 21E. good. On the posting server 11 side, it is preferable to authenticate the received cancellation information in the same way as for posted information. When distributing posting target information after receiving cancellation information, it may also include information such as the fact that cancellation information has been received and the number of canceled posts. A canceled post display field for displaying this information may be added to the data display screen 21L of FIG. 21. Furthermore, the accuracy of cancellation information is evaluated based on the number of postings of similar cancellation information and the share of highly rated posters, etc., and when the accuracy exceeds a predetermined threshold, distribution of the corresponding post target information is stopped. It's also good to do.

Note that after the distribution of the posted target information is finished, the original posted information may be stored in the new information storage area. This posted information is useful as reference information when considering whether to newly register posted target information in existing traffic information.
After finishing the distribution of the posting target information, it is preferable that the poster evaluates each piece of posted information in the posted information list in FIG. 17, and the evaluation results are reflected in the contents of the evaluation items. If a poster posts correctly, his/her post rating will increase steadily, while if a poster posts incorrectly, his or her post rating will continue to drop, leading to a difference in posting ratings. If the difference in post evaluation becomes noticeable, when the posting server 11 receives posted information, it will be easier to decide how to handle it, and the integrated information will be easier to integrate, which will improve the accuracy of posted target information. .
Instead of this example, the system may accept posts from posters who cannot be identified, while handling information posted by unspecified people as posted information with low accuracy. In this case, the number of posts can be increased.

In this example, the posted target information is displayed in different colors depending on the accuracy. In addition to this, the threshold value regarding the accuracy of whether or not to display posted target information may be adjustable by the user's operation. In addition, the display mode of posting target information with respect to accuracy may be configured to be settable by a user's operation.

Note that the configuration may be such that the position of the posting pin 262 on the map can be corrected by a user operation such as dragging after the posting pin 262 is registered on the mobile terminal 2 and before the posting information is sent. In this case, pin correction information indicating that the position correction operation of the posting pin 262 has been performed may be included in the posting information. The posting server 11 may treat posted information that includes pin correction information as having higher location accuracy than posted information that does not include pin correction information, and may reflect this in the location information of the posted target information. good.

The mobile terminal 2 may be configured so that the position of the target icon 261R (FIG. 20) of posted target information can be corrected by user operation. Furthermore, it is also possible to include icon correction information indicating that the position correction operation of the target icon 261R has been performed in the posted information. On the posting server 11 side, it is preferable to treat posted information including icon correction information as having high positional accuracy, and to reflect this in the positional information of posted target information.
It is also good to provide the posting server 11 with a map database. By performing well-known map matching using map data so that the monitoring position related to the posted information is located at a specific point, the positional accuracy of the monitoring position can be ensured and the positional accuracy of the posted target information can be improved. The specific point in map matching may be, for example, a point on a road or a point where a crackdown was carried out in the past.

The mobile terminal 2 of this example displays a data display screen 21L that displays detailed data of posted target information, etc., as shown in FIG. 21, in response to a touch operation on a target icon 261R (FIG. 20) related to posted target information. In this data display screen 21L, posters are displayed as a list in order of posted information time, but instead of this, posters with high overall evaluation points may be displayed in a ranking manner.

In this example, as shown in FIG. 4, the overall evaluation points of posters are determined based on the number of correct posts and the rate of correct posts, and based on this, the accuracy of posted information by each poster is evaluated. As an alternative method of evaluating the accuracy of posted information, there may be a method based on evaluations from other users, a method of evaluating according to the degree of proximity to past enforcement position data collected in advance, etc. For example, it may be configured such that when the target icon 261R (FIG. 20) of the posted target information is touched (for example, double-tapped), the monitoring position of the integrated original posted information is displayed. Furthermore, by configuring the system so that the evaluation screen of the corresponding poster can be switched and displayed by touching each monitoring position, each poster can be evaluated relatively easily from the mobile terminal 2 side.

(Example 2)
The driving support system 1 of this example is an example in which the configuration of the posting terminal is changed based on the driving support system of the first embodiment. The contents will be explained using FIGS. 1, 2, and 25 to 44.

Such a built-in position is suitable for receiving radio waves and the like coming from the front of the vehicle. In addition, in the microwave receiver 422, five levels of microwave electric field strength are set from Lv1 to Lv5 from the lowest strength to the lowest strength.

The clock unit 426 is a clock that outputs calendar information. The calendar information includes data representing the year, month, and day, and data representing the current time. When the current time can be obtained from the GPS receiver 421 once a day, the current time (including date and time) of the clock unit 426 is calibrated using that time.
The speaker 46 is assembled within the case body 5 so that it can output audio and the like through a speaker hole (not shown) opened in the bottom surface of the case body 5.
The memory card reader 47 transfers the data recorded on the memory card 471 to the reading control section 40. A memory card 471 inserted into the card insertion slot 57 is attached to the memory card reader 47.

The control unit 40 is constituted by a microcomputer (not shown) including a CPU, nonvolatile memory such as ROM, RAM, and EEPROM, I/O, and the like.
The ROM stores software programs and the like that are executed by the CPU.
A storage area of a non-volatile memory such as an EEPROM is provided with a setting information storage area for storing setting information such as alarm settings.

The database 400 is configured by a nonvolatile memory (eg, EEPROM) inside the microcomputer of the control unit 40 or externally attached to the microcomputer.

There is. Further, the database 400 stores a large amount of voice data used for text to speech (TTS).

Data stored in the database 400 can be updated using a memory card 471. When a memory card 471 storing updated data such as map data, GPS content, and audio output information is inserted into the memory card reader 47, the updated data is read out under the control of the control unit 40, and the data in the database 400 is read out. can be updated. In particular, by adding or updating audio output information, it is possible to change the manner of pronunciation and increase variations. Note that it is also possible to update the database 400 by connecting a PC with update data stored in a hard disk or the like via USB.

A storage area of a non-volatile memory (for example, EEPROM) within the microcomputer of the control unit 40 or external to the microcomputer is further provided with a posting pin storage area for storing information regarding traffic monitoring activities to be posted. The posted pin storage area can store up to four pieces of posted pin information related to traffic monitoring activities to be posted. Note that the data specifications of posted pin information in this example are slightly different from those in the first embodiment. The data specifications of posted pin information will be explained later with reference to FIG. 32 and the like.

The radar detector 4 realizes various functions by causing the CPU to execute software programs read from the ROM. The functions of the radar detector 4 include a display function for displaying various screens on the touch panel 45, an alarm function for issuing various alarms, an OBD function, a setting function, a registration function, and the like. As the alarm function, there are functions included in a general radar detector, such as a GPS alarm function, an RD alarm function, and a radio alarm function. Furthermore, the radar detector 4 of this example has a posted information generation function that generates posted information, and a code display function that converts posted information into a code image and displays it. Each means for realizing these functions is formed in the control section 40.

The OBD function is a function for acquiring vehicle information via an OBD port (failure diagnosis port) provided on the vehicle side based on the OBD2 standard, which is a vehicle inspection standard. This OBD function functions only in a situation where the radar detector 4 is connected to the vehicle side via an OBD adapter cord including an OBD connector connected to the OBD port on the vehicle side. Vehicle information that can be obtained from the OBD port of the vehicle includes, for example, vehicle speed, engine speed, engine load factor, ignition timing, intake manifold pressure, intake air flow rate (MAF), injection opening time, engine coolant temperature (cooling water temperature), temperature of the air taken into the engine (intake temperature), air temperature outside the vehicle (outside air temperature), fuel flow rate, instantaneous fuel consumption, accelerator opening (throttle opening), turn signal information (left and right turn signal operation information) , brake opening degree, steering wheel rotation angle information, etc. Note that the OBD function captures vehicle information every 0.5 seconds.

The setting function is a function for making various settings regarding the operation of the radar detector 4. As shown in FIG. 28, the settings include alarm settings for determining whether to execute various alarms. Driving support modes based on alarm settings include normal mode, minimum mode, special mode, all-on mode, and manual mode. The normal mode is the initial setting mode when the product is shipped. In each mode other than the manual mode, the operation (on/off) corresponding to each alarm target is predefined. In manual mode, the user can manually set actions according to the alarm target. The minimum mode is a setting in which only the minimum necessary alarm targets are alerted in all of the RD alarm function, wireless alarm function, and GPS alarm function. The normal mode is a mode that emphasizes the balance between functions, and is set to issue an alarm on items of high importance among enforcement-related items in addition to the items in the minimum mode. In addition to the items in normal mode, special mode is set to alert on all items related to enforcement.

The registration function is a function for the driver, who is a user, to register personal points (my points) and areas (my area), and is executed by a registration means realized by software in the control unit 40.

The GPS warning function is a function that warns of approaching a warning target such as an Orbis (automatic speed control device). In the GPS alarm function, calculation processing for determining the distance between the location of the alarm target and the current location is repeatedly executed at predetermined time intervals (for example, 1 second). When this distance reaches a predetermined approach distance and an event called warning point approach occurs, a GPS warning indicating this event is executed.

Targets of alerts by the GPS alarm function include Orbis, enforcement areas, inspection areas, intersection monitoring points, parking monitoring areas, N systems, traffic monitoring systems, red light prevention systems, police stations, areas where accidents occur frequently, areas where targets on vehicles frequently occur, There are sharp curves, branching and merging points, and ETC lanes.

The posted information generation function is a function that generates posted information, similar to the posted information generation function of the mobile terminal in the first embodiment. The procedure for generating posted information will be explained later.
The code display function is a function that converts the generated posted information into a two-dimensional code image and displays it on the touch panel 45. In this example, a QR code (registered trademark) is used as the two-dimensional code image. Various code images such as a one-dimensional barcode can be used as the code image. Although the code image is a two-dimensional code, various code images such as a one-dimensional barcode may be used.
Instead of the code image, characters may be displayed and the characters may be recognized. Alternatively, wireless communication such as IRDA, IRDX, NFC, Bluetooth (registered trademark), etc. may be used.
You may combine these. It is preferable to adopt a configuration in which posted information is exchanged using a method that uses functions compatible with display functions and communication functions implemented in mobile terminals.

The basic operation of the warning function, which is the main function of the radar detector 4 having the above configuration and is realized by control of the control unit 40 and the like, will be explained. In a standby state in which a warning target event such as RD reception, radio reception, or approach to a warning point has not occurred, the standby state is such that a map screen 62 (FIG. 29) is displayed. When any event among warning point approach, RD reception, and radio reception occurs in the standby state, the control unit 40 executes the corresponding function among the GPS alarm function, RD alarm function, and radio alarm function. Execute the processing to be performed. Note that when two or more events occur simultaneously, the priority of each function is from the highest to the RD alarm function, the wireless alarm function, and the GPS alarm function.

On the map screen 62, as shown in FIG. 29, a map around the current location is displayed. On the map screen 62, the map is displayed so that the direction of travel of the vehicle always faces upward and the current position is at the bottom center of the screen. A host vehicle icon 601 is displayed at the current position. In the upper left corner of this map screen 62, a compass 626 for displaying an illustration of the direction of travel of the vehicle and a vehicle speed display 625 are arranged, and in the upper right corner, a time display 621 is arranged. At the lower left corner of the map screen 62, an address display 622 that displays the name of the town of the current location, etc. is arranged.

In the standby state, when a warning target event such as RD reception, radio reception, or warning point approach occurs, the control unit 40 superimposes warning information on the map screen 62 (pop-up display) and displays the warning content in audio. Output. At this time, the color of the light emitted from the light emitting unit 53 changes from blue, which represents the standby state, to red, thereby indicating that caution is required.
In the case of a GPS warning, as shown in FIG. 30, a photo display 628 of the enforcement point including a symbol display 629 of the warning contents, and a radar display icon (mini radar) 627 indicating the remaining distance and direction are pop-up displayed on the map screen 62.
In the RD warning, as shown in FIG. 31, a photograph display 628 of the enforcement point including a symbol display 629 of the warning contents, and a radar display icon 627 indicating the remaining distance and direction are pop-up displayed on the map screen 62. Note that as the remaining distance of the radar display icon 627, the distance estimated from the electric field strength (Lv1 to Lv5) of the received radar wave is displayed.
In the case of a wireless alarm, a wireless alarm screen, which is not shown because it is almost the same as the RD alarm, is displayed.

Next, the data specifications of posted information (including posted pin information) handled by the driving support system of this example and the operation of the system will be explained.
The data specifications of posted information handled by the driving support system of this example are as shown in FIG. Note that, in the figure, illustration of header information and the like required for communication is omitted. In the posted information of this example, the member information of the first embodiment is replaced with product information (serial number, etc.) of the radar detector 4. In addition, the posted pin information in this example includes freshness information indicating the implementation time of the traffic monitoring activity to be posted, direction type information indicating the type of enforcement direction (Fig. 32 to Fig. 34) has been added. Note that the breakdown of each data such as X, Y, A, etc. that constitutes the posted pin information in FIG. 32 is as shown in FIG. 33(a). The contents of each data T, R, and M among the data shown in FIG. 3(a) are as shown in FIG. 2(b), (c), and (d).

The freshness information is information indicating the implementation timing of the traffic monitoring activity to be posted. As shown in FIG. 33(c), data values representing freshness are defined according to the implementation timing of the target traffic monitoring activity. For example, if the posted information targets a traffic monitoring activity that is currently being carried out, the freshness value will be zero, and if the posted information targets a traffic monitoring activity that was carried out over one week but within one month, the freshness value will be zero. For example, the freshness value is 20. On the other hand, the freshness data value is 255 for posted information targeted at permanently installed type Orbis and the like.
The direction type information is information that supplements the enforcement direction included in the position information. By using the direction type information, it is possible to specify the enforcement direction for monitoring activities in the opposite lane, as well as specifying whether traffic monitoring activities are to be carried out on the right or left side of the driving lane. For example, in the case of a traffic monitoring activity targeting a driving lane, 0x01, which is a 180 degree inversion of the traveling direction 0x02 (vehicle traveling direction) in FIG. 34, is the type of enforcement direction. For example, when a posting pin is registered in front of an Orbis installed in a median strip, it means that the Orbis is set diagonally to the right of the driving lane. The type of enforcement direction in this case is direction 0x10 in the figure.

In the driving support system 1 of this example, (1) generation of posted target information using the radar detector 4, (2) transmission of posted information using the mobile terminal 2, (3) authentication of posted information by the member management server 12, The various operations and the like are different from the driving support system of the first embodiment. The contents of each operation (1) to (3) will be explained below.

(1) Generation of posted information When the control unit 40 of the radar detector 4 detects the operation of the memory button 522 while the map screen 62 of FIG. A registration menu button 63 is displayed as a pop-up on the screen. The registration menu buttons 63 include, in addition to a pin setting button 634 for registering a posting pin 64 (FIG. 36), an ITY map button 631 that displays the latitude and longitude of the vehicle's position when the button is pressed as a two-dimensional barcode; There is a My Area button 632 for registering My Area and a Cancel button 633 for canceling the registered area.

When the pin setting button 634 is touched, the control unit 40 sets the posting pin 64 at the current position on the map screen 62 as shown in FIG. ) and the pin registration time are registered in the posted pin storage area. In the radar detector 4 of this example in which a maximum of four pieces of posted pin information can be registered in the posted pin storage area, it is possible to register up to four posted pins 64 from the first pin to the fourth pin. In the figure, since all the pins were empty, the first pin was set at the current position as the posted pin 64, and the position information, pin registration date and time, etc. at that time were stored in association with the first pin. This is an example. Note that activity content information indicating the type, implementation mode, method, etc. of the traffic monitoring activity is generated in response to subsequent user operations (FIGS. 40 to 42) and stored in the posting pin storage area.

If all four posted pins 64 have been registered and information on the four posted pins is stored in the posted pin storage area, the registration menu button 63 shown in FIG. 37 will pop up in response to the operation of the memory button 522. Ru. Here, the registration menu button 634A including the display of "Pins are full" displays that the posted pin 64 (FIG. 36) cannot be registered.
In addition, in this example, since the enforcement direction is essential information in the posted information, similarly to the first embodiment, the posting pin 64 cannot be registered when the heading direction by the GPS function is not determined. There is. When the memory button 522 is operated in a state where the heading is undetermined, the control unit 40 pops up the registration menu buttons 63 including the registration menu button 634B representing the undetermined heading (FIG. 38). Further, when the memory button 522 is operated in a non-positioning state where positioning is not performed using the GPS function, the control unit 40 displays a caption indicating that a GPS search is in progress at the top of the map screen 62 (Fig. 39 ).

When the control unit 40 detects a touch operation on the map screen 62 (FIG. 29, etc.), it displays the top setting screen 67A in FIG. Various menu buttons are arranged on this setting screen 67A, including a posting button 670 for posting posted information. When the post button 670 is touched, the control unit 40 switches the display to the post pin menu screen 67B shown in the middle in the figure. This posted pin menu screen 67B is a screen in which a confirmation button 671A and a delete button 671B are arranged for each posted pin. Note that for unregistered posted pins, the operation buttons 671A and 671B are displayed in shadow and become inoperable. When the control unit 40 detects a touch operation on the pin confirmation button 671A, it reads posted pin information corresponding to the posted pin from the posted pin storage area. The control unit 40 displays position information (latitude and longitude, address, enforcement direction) and time information (pin registration date and time) in text among the posted pin information that has been read out, as well as a post button 672 for starting the posting process, etc. The placed pin confirmation screen 67C is displayed. Generation of posting information is started in response to a touch operation on this posting button 672.

As shown in FIG. 41, when the control unit 40 detects a touch operation on the post button 672 on the pin confirmation screen 67C, the control unit 40 changes the post screens 67D to 67I in FIGS. 41 and 42 as appropriate depending on the type of traffic monitoring activity, etc. , is displayed on the touch panel 45. The posting screens 67D to 67F in FIG. 41 are screens for generating activity content information (FIG. 32) such as the type (category) of the traffic monitoring activity to be posted, its implementation mode, and method. The posting screens 67D to 67F correspond to the posting screens 21G to 21I (FIGS. 13 to 16) of the first embodiment, respectively. The control unit 40 adds activity content information generated in response to user operations on the posting screens 67D to 67F to posted pin information stored in the posted pin storage area. Note that, except for the posting screen 67D for selecting the type of traffic monitoring activity to be posted, the posting screens 67E and 67F for selecting the implementation mode, method, etc. are provided with operation buttons for selecting "other" or "unknown". The purpose of providing operation buttons for selecting "Other" etc. on the posting screens 67E and 67F is to make posting easier and more active for users who are not very familiar with traffic enforcement.

The posting screen 67G in FIG. 42 is an operation screen for inputting freshness information (FIG. 32) representing the implementation time of the traffic monitoring activity to be posted. This posting screen 67G includes an operation button for selecting currently in progress, an operation button for within one week, an operation button for within one month, an operation button for within three months, etc. While the driving support system 1 of Example 1 is a system that is intended for posting about currently ongoing traffic monitoring activities, the system of this example also allows posting about past traffic monitoring activities. It has become. The control unit 40 adds freshness information corresponding to the operation button selected on the posting screen 67G to the posted pin information stored in the posted pin storage area.
The posting screen 67H is a posting screen for selecting the type of enforcement direction. This posting screen 67H includes "driving lane", "opposite lane", "right direction", "left direction", "right side of driving lane", "left side of driving lane", "left side of opposite lane", and "opposite lane". The operation button for "Right side of the lane" is located. The control unit 40 adds orientation type information (FIGS. 32 to 34) corresponding to the operation button selected on the posting screen 67H to the posted pin information stored in the posted pin storage area.

When any of the operation buttons on the posting screen 67H is operated as described above, the generation of posting pin information (FIG. 32) is completed. The control unit 40 reads posted pin information from the posted pin storage area, adds product information (FIG. 32), and generates posted information. Then, a code image 670 in which this posted information is recorded is generated, and a posted screen 67I including this code image 670 is displayed on the touch panel 45 as shown in FIG.
The posting user only has to take a picture of the code image 670 using the mobile terminal 2 that has activated posting software that supports code images. The mobile terminal 2 that photographed the code image 670 executes image processing, cuts out the code image 670 from the photographed image, and reads posted information recorded in the code image 670. The control unit of the mobile terminal 2 immediately transmits the posted information read in this way to the posting server 11.

When the posting server 11 receives posted information, it first requests authentication from the member management server 12. The member management server 12 requested for authentication refers to the user management database 121 using the product information (serial number, etc.) received from the posting server 11, and determines whether the corresponding purchaser exists. When the relevant purchaser exists validly, the poster ID of the purchaser is returned from the member management server 12. When the posting server 11 receives authentication from the member management server 12, it refers to the user status database 113 and checks whether there is a posting prohibition flag for the poster. The posting server 11 deletes posted information for which the posting prohibition flag is set without accepting it, while executing an acceptance process for posted information for which the posting prohibition flag is not set.

The reception process in this example is different for posted information whose freshness information (FIG. 33) has a data value of zero and for other posted information. Real-time posted information for which the freshness information is zero, that is, for traffic monitoring activities currently in progress, is handled in the same manner as in the first embodiment, and becomes the source information for the posted target information for distribution.
On the other hand, regarding other posted information, that is, posted information related to permanent traffic monitoring activities such as the N system (data value of freshness information is 255), and posted information related to past traffic monitoring activities, Example 1 of the posting server 11 It is stored in the same new information area and becomes the source information for existing traffic information to be newly registered.
Note that the other configurations and effects are the same as in Example 1.

Note that the posting screens 67E to 67H (FIGS. 41 and 42) may be provided with an "immediate posting button" for jumping to the posting screen 67I. If one of the Orbis button, N system button, enforcement button, and inspection button is selected on the posting screen 67D corresponding to the posting screen 21G (FIGS. 13 to 16) of the first embodiment, the type of traffic monitoring activity is determined. . After the type of traffic monitoring activity is determined in this way, even if the immediate post button on the posting screens 67E to 67H is operated thereafter, it is possible to generate posted information that includes type information representing the determined type. .

The registered posted pin 64 (FIG. 36, etc.) can be deleted by operating the delete button 671B on the posted pin menu screen 67B in the middle of FIG. 40. When this delete button 671B is operated, the deletion of the corresponding posted pin is completed via a screen for confirming deletion and a screen for displaying that deletion is completed, as shown in FIG. 43(a). By operating the system button located at the lower right corner of the setting screen 67A at the top of FIG. 40, the data deletion screen can be switched and displayed as shown in FIG. 43(b). By selecting the posted pin button on this data deletion screen, you can delete posted pins and corresponding posted pin information all at once.

Similar to the first embodiment, the posted target information distributed by the driving support system 1 of this example is information regarding the traffic monitoring activity currently being carried out. Alternatively or in addition to this, it is also possible to distribute posted target information generated by integrating posted information regarding past traffic monitoring activities whose freshness information (FIG. 33) is other than 255 or zero. In this case, for example, one or more posted information for traffic monitoring activities conducted two months ago, posted information for the same type of traffic monitoring activity one month ago, and information posted for the same type of traffic monitoring activity conducted within one week. Posted information regarding traffic monitoring activities can be integrated to generate posted target information regarding points of interest where traffic monitoring activities are frequently performed.
In addition, here, in order for the above one or more posted information to be classified as posted information for common traffic monitoring activities two months ago, temporal proximity and locational proximity regarding implementation time are required. and commonality of types need to be satisfied. In addition, in order for posted information about a traffic monitoring activity that was similarly conducted one month ago to be classified as information about a common traffic monitoring activity compared to information posted about a specific traffic monitoring activity from two months ago, location Two conditions need to be met: physical proximity and commonality of type.

In this example, posted information is transferred to the mobile terminal 2 using a code image 670 (FIG. 42) displayed by the radar detector 4. Alternatively, the posted information may be transferred by connecting the radar detector 4 and the mobile terminal 2 in a communicable state through wireless communication such as WiFi (see FIG. 1). For example, if you operate the post button displayed on the touch panel 45 of the radar detector 4 while the dedicated software is running on the mobile terminal 2, the posted information will be posted via the mobile terminal 2. It is also good to configure it like this. In order to provide the radar detector 4 with a WiFi function, a WiFi module or the like may be incorporated. The mobile terminal 2 may be any mobile terminal as long as it has an access point (tethering) function.

If the radar detector 4 is capable of wireless communication with the mobile terminal 2, it is possible to receive the posted target information via the mobile terminal 2. It becomes possible for the radar detector 4 to notify posted target information, issue a warning, etc. Furthermore, if the public enforcement information is distributed, the radar detector 4 can broadcast the public enforcement information as shown in FIG. 44. The radar detector 4 illustrated in the figure scrolls and displays the distributed public enforcement information at the bottom of the map screen 62.

Note that the driving support system may be compatible with both the posted information of the first embodiment and the posted information of this example. The posted information of Example 1 and the posted information of this example may be integrated to generate posted target information. In this case, the posted information generated by the mobile terminal 2 and the posted information generated by the radar detector 4 may be evaluated differently. For example, it can be assumed that a poster who has purchased and actually uses the radar detector 4 is a person who places importance on the warning function and the like and has a wealth of knowledge regarding traffic enforcement. There is a high possibility that the accuracy of information posted by such posters can be highly evaluated.

In this example, the cumulative points of the posted information list (FIG. 17) are used as the accuracy of posted target information. In addition to this, the accuracy may be evaluated based on the implementation history of past traffic monitoring activities. For example, if there is a history of similar traffic monitoring activities being carried out in the past, you can set the accuracy to 120% of the cumulative points (20% more value), or add historical points to the cumulative points. It is also good to do As history points, it is good to use points that reflect the frequency of implementation. When determining the implementation history of past traffic monitoring activities, in addition to using existing traffic information, it is also good to use posted target information in the latest information area.

It is also possible to change the notification or warning mode of posted target information depending on the vehicle information acquired by the OBD function, such as the speed of the vehicle. For example, if the speed exceeds the speed limit, posting target information regarding mobile Orbis etc. becomes very important.

(Example 3)
This example is based on the driving support system of the first embodiment, and provides a case where posted information is distributed as is. The contents will be explained with reference to FIG. 17 and FIGS. 45 to 47.

Posted information to be distributed includes, for example, posted information where the poster's post evaluation points are, for example, 8 or more and have not yet been reflected in the posted target information, and changes in the monitoring position such as a patrol car. As a result, there are posted information, etc. for which real-time performance is important.
FIG. 45 is a display example of posted information regarding a police motorcycle being patrolled. In the figure, an information pin 271 is displayed on a map displayed on the touch panel 21 of the mobile terminal 2 at a monitoring position corresponding to posted information of a police motorcycle being patrolled. The figure also shows a balloon display 275 that is displayed when the information pin 271 is tapped (touch operation). The balloon display 275 displays the date and time of posting, the details of the traffic monitoring activity related to the posted information, and the like. In addition, for posted information where real-time performance is important, a limit such as 6 hours is set for the display time, this time limit is managed on the mobile terminal 2 side, and the information pin 271 is deleted as the time limit passes. It's also good to do. Note that the illustration of the information pin 271 may be changed depending on the type of target traffic monitoring activity, and the display color and size of the information pin 271 may be changed depending on the degree of risk.

Furthermore, in the figure, a scroll display field 278 is provided at the bottom of the display screen of the touch panel 21. This scroll display field 278 is a display field for posted information, among the posted information distributed as described above, whose monitoring position is not included in the map area displayed on the touch panel 21. By providing such a display, it is possible to display posted information whose monitoring position is far away and not included in the map area. As the far range, a range such as 20 km can be set. Further, it is also possible to selectively display posted information from far away located in the direction of travel of the vehicle, posted information from far away located on the road on which the vehicle is traveling, and the like. Note that the public enforcement information in FIG. 24 referred to in Example 1 may be displayed in the scroll display field 278, but in this case, the background color may be changed between the public enforcement information and the posted information, etc. It would be a good idea to devise ways to make it easier to distinguish between public regulatory information and public enforcement information.

For example, the configuration shown in FIG. 46 can be adopted as a message configuration when scrolling and displaying posted information. In the case of a message structure like this, for example, "Yuppi-san (35) June 6th 10:30 am [Speed Control (Radar)] In front of Yupitel, Iwazu-cho, Okazaki City, Aichi Prefecture I'm doing this at the usual place. Be careful! ” and other messages can be scrolled. As for the posting experience value, it is good to have a value that increases in proportion to the number of postings. For example, the number of correct posts, comprehensive evaluation, etc. shown in FIG. 3 may be used as the posting experience value. In addition, in order to increase the number of posting enthusiasts who like posting, it is effective to hold events such as awarding prizes to the top three posting experience points in a year. It is also a good idea to equip the posting server with a program that selects the top 3 posting experience points of the year at the end of the year. Such an event provides an incentive for posting and contributes to the collection of more accurate posted information.

The posting information may be automatically distributed (for example, every 10 minutes) from the posting server. As shown in FIG. 45, an update button 272 may be provided, and distribution may be executed immediately in response to the operation of this update button 272. Furthermore, the posted information may be selectively distributed only to desired users. This is because some users do not wish to receive posted information that is not sufficiently accurate.

In order to distribute posted information, it is also possible to use distribution files for each of the 47 prefectures. By using such a distribution file, for example, posted information within Aichi Prefecture can be distributed all at once to users who are driving within the prefecture. When distributing distribution files for each prefecture, in addition to the distribution files for the prefecture to which the current location belongs, the distribution files for adjacent prefectures may be simultaneously distributed. Further, the posted information to be included in the distribution file may be limited to posted information within 6 hours from the posting time (the time when the posting server receives it). For example, the posted information for one item may have the following contents.
・Latitude and longitude Example: 34.794025 degrees, 137.117188 degrees ・Display period Example: June 6, 2012 10:25 a.m. to June 6, 2012 16:25 ・Enforcement content Example: Speed enforcement (white motorcycle)
・Address information Prefecture Example, Aichi Prefecture City name Example, Nishio City Town name address Example, ○○ Town 2・Details Location and nearby landmarks (sometimes without data)
Example: Road heading towards Koda from the intersection between Nishihazu JA and Sugi Pharmacy/Comments (sometimes without data)
For example, this is a place where I often work. Be careful of the 40km speed limit.
・User information User name Example, Yuppi Posting experience value Example, 121

In the mobile terminal 2 of this example, generation of posted information can be started by touching the posting button 273 in FIG. 45. When the post button 273 is touched, a post page (not shown) is displayed. This posting page displays text information such as latitude/longitude, year/month/day/hour/minute, and address information when the posting button 273 is touched, as well as operating means such as a rotating drum for selecting the type of traffic monitoring activity, etc. It is also good to have a picker view. For detailed locations and comments, it is better to have the user enter text. Note that in order to accommodate posters who find it troublesome to input text, it may be possible to pass input for detailed locations and comments. It is also a good idea to configure the posting server to add a clever comment if the comment is passed.
Note that the other configurations and effects are the same as in Example 1.

In this example, posted information from far away outside the map area is scrolled and displayed at the bottom of the screen. Instead, as shown in FIG. 47, posted information whose monitoring position is located on the right side of the map area is scrolled and displayed in the strip-shaped space 278R at the right end of the screen, and the monitoring position is located on the upper side. The posted information may also be scroll-displayed in the space 278U at the top of the screen. In this case, it becomes possible to grasp the direction of far-off posted information according to the scroll-displayed position.
