Description

  The present invention relates to an information processing system, an information processing apparatus, an information processing method, and a program for measuring the speed of vehicles such as automobiles and trains.

  At present, major highways are equipped with an automatic speed control machine (hereinafter referred to as a speed control machine) known as “Obis” to control speeding. This speed control machine measures the speed of a vehicle that travels greatly exceeding the speed limit on a specified speed limit road, and also photographs the number plate of the vehicle and the face of the driver. The police identify the driver who has violated the speed from the measured speed, the number of the photographed license plate and the driver's face, and notify the driver of the speed violation. In this way, it is possible to prevent accidents caused by excessive speed on the expressway by cracking down on speeding.

On the other hand, a traffic jam detection system that detects the speed of a traveling vehicle and determines the presence or absence of traffic jam from the detected speed is disclosed (for example, see Patent Document 1).
JP 2000-67288 A

  The speed control machine described above is often a fixed type fixed to the side of the road, except in the case of a temporary control called a mobile orvis. Therefore, the driver can know the position of the enforcement machine once it passes through the place where the fixed speed enforcement machine is installed. In addition, although the position of the speed enforcement machine cannot be specified accurately, in most cases, a notice that the speed enforcement machine is installed is installed beside the road.

  As described above, the driver often knows the position of the speed regulator in advance, and even if the vehicle is traveling at a speed exceeding the speed limit, the speed of the vehicle is reduced in front of the speed regulator. By doing so, it becomes possible to escape from speeding control. For this reason, the low rate of the number of cases that could actually be controlled against the expected number of speeding violations has become a problem. Therefore, the rate of traffic accidents due to excessive speed remains at a high level.

  In addition, before and after the range where the speed regulator can measure the speed of the vehicle, the driver tends to drive the vehicle at a speed that exceeds the speed limit and involves other vehicles before and after that range. There was a risk of an accident.

The average speed of the vehicle is obtained from the time and the distance, and it is determined whether or not the obtained average speed violates the speed regulation.

  The configuration of the information processing system of the present invention will be described. In this embodiment, it is assumed that the information processing system of the present invention is applied to a toll freeway.

  FIG. 1 is a block diagram showing a configuration example of an information processing system according to the present invention.

  As shown in FIG. 1, the information processing system includes an in-vehicle device 1 serving as an information terminal provided in a car, a reading device 2, 3 serving as a base station device that collects information from the on-vehicle device 1, and a reading device 2, 3 And an information processing device 4 that manages the information collected. The information processing apparatus 4 is provided in the information management center. The readers 2 and 3 are provided at the entrance and exit of the toll gate on the highway, the entrance and exit of the service area, and the road with a long straight line. In FIG. 1, only two reading devices 2 and 3 are shown for ease of explanation.

  The information processing device 4 is communicably connected to a posting device (not shown) provided on the side of the road, and displays the results of the calculation operation and the determination operation using information from the reading devices 2 and 3 on the posting device. Let This bulletin board displays characters and figures in such a size that the driver can confirm the contents of the bulletin even from a car running on a highway at high speed.

  Next, the configuration of each device will be described. Since the reading device 2 includes the reading device 3 and has the same configuration as other reading devices not shown in the drawings, the reading device 2 will be described below as a representative of the reading device.

  FIG. 2 is a block diagram illustrating a configuration example of the vehicle-mounted device and the reading device.

  As shown in FIG. 2A, the vehicle-mounted device 1 displays a terminal storage unit 11 in which different vehicle identifiers are stored for each vehicle, a terminal communication unit 12 for transmitting / receiving information to / from the reading device 2, and information. For this purpose, the display unit 13 and a terminal control unit 14 for controlling each unit are provided.

  As shown in FIG. 2 (b), the reading device 2 includes a base station storage unit 21 for storing information received from the vehicle-mounted device 1, and a base for transmitting / receiving information to / from the vehicle-mounted device 1 and the information processing device 4. The configuration includes a station communication unit 22, an antenna 25 for transmitting and receiving information by radio waves, and a base station control unit 23 for controlling each unit.

  The terminal control unit 14 and the base station control unit 23 include a CPU (Central Processing Unit) that executes predetermined processing according to a program and a memory for storing the program.

  The vehicle-mounted device 1 and the reading device 2 perform transmission / reception of information by, for example, narrow band wireless communication (DSRC: Dedicated Short Range Communication) used in ETC. In DSRC, the communicable distance is several meters to several tens of meters. In this embodiment, since the reading device 2 is provided at the entrance / exit of the toll gate on the highway or the entrance / exit of the service area, the distance between adjacent reading devices can be made larger than several tens of meters.

  The information processing device 4 and the reading device 2 transmit and receive information by packet communication via a mobile phone communication network. In addition, since it is the same as that of a general method about narrow area | region wireless communication and packet communication, the detailed description is abbreviate | omitted.

  The base station control unit 23 of the reading device 2 periodically transmits radio waves via the antenna 25, and is an identifier that is a signal for requesting a vehicle identifier from the vehicle-mounted device 1 that has entered a predetermined range (area). Send a request signal. And if a vehicle identifier is received from the onboard equipment 1 of the vehicle which entered the area, it will be stored in the base station memory | storage part 21 with a vehicle identifier as a passage time at the received time. When the passage information including the vehicle identifier and the passage time of the vehicle entering the area is stored for a certain time, the stored passage information is transmitted to the information processing device 4 of the information management center. Thereafter, when a reception confirmation signal indicating that the passage information is received from the information processing device 4 is received, the passage information transmitted to the information processing device 4 is deleted from the base station storage unit 21. If the information transmitted to the information processing device 4 is deleted from the base station storage unit 21, it is not necessary to increase the storage capacity provided in the base station storage unit 21. Therefore, it is possible to reduce the cost for the equipment.

  When receiving the identifier request signal from the reading device 2, the terminal control unit 14 of the vehicle-mounted device 1 transmits the vehicle identifier stored in the terminal storage unit 11 to the reading device 2. Note that information exchange between the vehicle-mounted device 1 and the reading device 2 is possible with an ETC facility.

  FIG. 3 is a block diagram illustrating a configuration example of the information processing apparatus.

  As shown in FIG. 3, the information processing device 4 transmits and receives information to and from the storage unit 41 in which the section distance that is the distance between adjacent reading devices and the reference speed of each section is stored. The configuration includes a communication unit 42, a control unit 44 that obtains the average speed of the vehicle using the passage information received from the reading device 2, and a display unit 43 that displays the obtained average speed. The control unit 44 includes a CPU that executes predetermined processing according to a program and a memory for storing the program.

  The storage unit 41 stores an upper limit value and a lower limit value of the reference speed together with the reference speed. The upper limit value is a criterion for determining whether or not to crack down as a speed violation, and the lower limit value is a criterion for determining whether or not there is congestion in the corresponding section. The upper limit value and the lower limit value are set in advance by the operator of the information processing device 4. The reference speed is, for example, a speed limit.

  When receiving the passage information from the reading device 2 at regular intervals, the control unit 44 stores the passage time of each point in the storage unit 41 for each vehicle identifier, and transmits a reception confirmation signal to the reading device 2. And the average speed between readers is calculated | required about each vehicle from the stored passage time and the distance between readers stored beforehand. When the obtained average speed exceeds the reference speed, the average speed is compared with the upper limit value of the reference speed. When the average speed is larger than the upper limit value, it is determined that the speed is violated, and the vehicle identifier and the information indicating that the speed is violated are stored in the storage unit 41 for the vehicle having the average speed. When the average speed is smaller than the upper limit value, the display unit 43 displays information indicating that the average speed and the speed are exceeded.

  On the other hand, when the calculated average speed is smaller than the reference speed, the control unit 44 compares the average speed with the lower limit value of the reference speed, and when the average speed is larger than the lower limit value, the control unit 44 determines the time required for the corresponding section. Display on the bulletin board. When the average speed is smaller than the lower limit value, information indicating that a traffic jam has occurred is displayed on the posting device in addition to the time required for the corresponding section.

  In this embodiment, the distance between the sections is several kilometers to several tens kilometers. Therefore, even if the communicable range between the reading device 2 and the vehicle-mounted device 1 is several tens of meters and a difference of several tens of meters occurs in the distance between the sections, the average speed calculation is within the error range. Don't be.

  Next, the passage information and the section distance stored in the storage unit 41 of the information processing device 4 will be described.

  FIG. 4A is a table showing an example of passage information stored in the storage unit, and the passage time is displayed in “hour: minute”. FIG. 4B is a table showing the distance of each section stored in the storage unit.

  “A doorway” to “E doorway” in FIG. 4A indicate points where reading devices are installed. “Gateway A” and “Gateway E” are interchange toll booths, and “Gateway D / Exit” are service area entrances and exits. In the present embodiment, the distance between BCs is a long straight road that is easy to speed up, so points B and C are also the installation positions of the reading device. The vertical column of the table is divided by vehicle identifier, and the notification time of each point is described for each vehicle. The table of FIG. 4A shows a state after the control unit 44 adds passing information when the vehicle identifier “10002” passes through the point B.

  As shown in FIG. 4B, the distance of each section is 40 km between AB, 6 km between BC, 6 km between CDs, and 25 km between DEs.

  Next, an operation procedure of the information processing system configured as described above will be described. Here, it is assumed that the passage information and the section distance shown in FIG.

  FIG. 5 is a flowchart showing an operation procedure of the information processing system. Although the vehicle-mounted device 1 has an ETC function, the operation related to the toll on the highway is the same as the conventional one, and thus detailed description thereof is omitted.

  The reading device 2 periodically transmits an identifier request signal via the base station communication unit 22 (step S101). An identifier request signal transmitted by the reader 2 when the vehicle with the vehicle identifier “10001” enters the range in which signals can be transmitted and received between the vehicle-mounted device 1 and the reader 2 while attempting to pass through the entrance / exit of the highway A. Is received by the vehicle-mounted device 1. When receiving the identifier request signal from the reading device 2, the vehicle-mounted device 1 transmits the vehicle identifier to the reading device 2 via the terminal communication unit 12 (step S102).

  When receiving the vehicle identifier from the vehicle-mounted device 1, the reading device 2 stores the passage information including the vehicle identifier and the passage time in the base station storage unit 21 using the received time as the passage time (step S103). When the reading device 2 stores the predetermined time passage information, the reading device 2 transmits the stored passage information to the information processing device 4 via the base station communication unit 22 (step S104). When the information processing device 4 receives the passage information from the reading device 2, the information processing device 4 stores the passage information in the storage unit 41, and transmits a reception confirmation signal to the reading device 2 via the communication unit 42 (step S105).

  When receiving the reception confirmation signal from the information processing device 4, the reading device 2 deletes the passage information transmitted to the information processing device 4 from the base station storage unit 21 (step S106).

  Thereafter, information is transmitted / received among the vehicle-mounted device 1, the reading device 2, and the information processing device 4 in the same manner for other points of the vehicle identifier “10001” and other points in other vehicles. Thereby, the passage information is stored in the storage unit 41 of the information processing apparatus 4 as shown in the table of FIG. The information processing apparatus 4 performs the calculation operation and the determination operation described below using the passage information and the section distance stored in the storage unit 41 (step S107).

  Next, the operation procedure of the information processing apparatus 4 will be described.

  FIG. 6 is a flowchart showing an operation procedure of the information processing apparatus. Here, the table shown in FIG. 4 is used as the passage time and the section distance. The reference speed is 80 km / h, the upper limit is 1.2 times the reference speed (= 96 km / h), and the lower limit is 0.8 times the reference speed (= 64 km / h).

  The control unit 44 stores the passage time received from the reading device 2 at each point in the storage unit 41, and obtains the average speed of each section by calculation for each vehicle (step S201). The calculation method of the average speed will be specifically described in the case of the AB section with the vehicle identifier “10001”. The required time for the AB section can be obtained as “20 minutes” by calculating the difference between the time “10:30” of B and the time “10:10” of A from the table of FIG. And the distance of AB section is 40 km from the table | surface of FIG.4 (b). Therefore, the average speed in the AB section is 40 km / (20/60) h = 120 km / h. Thus, when the average speed of each section for each vehicle is obtained, the result shown in FIG. 7 is obtained.

  FIG. 7 is a table showing an example of the average speed of each section for each vehicle, and the unit of the number is [Km / h].

  The control unit 44 compares the average speed of the AB section of the vehicle identifier “10001” shown in FIG. 7 with the reference speed (step S202). Since the average speed is 120 Km / h, which is larger than the reference speed, the control unit 44 compares the average speed with the upper limit value (step S203).

  Since the average speed is larger than the upper limit value of 96 km / h, the control unit 44 stores the vehicle identifier “10001” and the fact that it is a speed violation in the storage unit 41 (step S204). On the other hand, if the average speed is smaller than the upper limit value in step S203, the display unit 43 displays that the average speed is in excess of the speed because the speed is not cracked down (step S205).

  In step S202, the control unit 44 compares the average speed of the AB section of the vehicle identifier “20001” shown in FIG. 7 with the reference speed. Since the average speed is 80 km / h and matches the reference speed, the control unit 44 compares the average speed with the lower limit value (step S206). Since the average speed is larger than the lower limit value of 64 Km / h, the control unit 44 causes the posting device to display the required time “30 minutes” of the AB section of the vehicle identifier “20001” (step S207).

  In step S202, the control unit 44 compares the average speed of the AB section of the vehicle identifier “10002” shown in FIG. 7 with the reference speed. Since the average speed is 40 km / h, which is smaller than the reference speed, the control unit 44 compares the average speed with the lower limit value (step S206). Since the average speed is smaller than the lower limit value of 64 km / h, the control unit 44 causes the bulletin board to display the required time “60 minutes” of the AB section of the vehicle identifier “10002” and the occurrence of traffic congestion in the AB section. (Step S208).

  In the present invention, as described above, since the vehicle identifier of the speeding vehicle is stored in the storage unit 41 of the information processing device 4, the speeding notification is sent to the owner of the vehicle specified by the vehicle identifier. Can be done.

  Further, if the bulletin board is provided at the entrance / exit A, the required time between AB is displayed on the bulletin board at step S207 in FIG. You can grasp the approximate time. If traffic jams occur between ABs, the required time between ABs and the fact that traffic jams occurred are displayed on the bulletin board in step S208. You can grasp the approximate time to arrive.

  In addition, the average speed is displayed on the display unit 43 in step S205 of FIG. 6, so that the operator of the information processing apparatus 4 can grasp the flow of the car on the highway. Even if there is no need to crack down as a speeding violation, there are many cars that exceed the reference speed, and if the average speed of the entire traveling car increases, the possibility of an accident increases. For this reason, it is possible to take measures to prevent an accident from the displayed average speed based on the judgment of the operator.

  If the reading device 2 is provided at the entrance / exit of the interchange, the existing ETC equipment can be used as it is. Moreover, by providing at the entrance / exit of the service area, power can be taken from the facility in the service area, and it is not necessary to lay a cable for supplying power along the road. In addition, since communication between the reading device 2 and the information processing device 4 uses a network such as a packet network, it is not necessary to lay a signal cable for communication. Therefore, resources can be used effectively.

  Although the required time is displayed on the bulletin board at step S207 and step S208 in FIG. 6 of the present embodiment, when there are a plurality of required time data, the average required time, which is an average value of the required time, is displayed. You may make it display on a bulletin board. In this case, a required time is provided in which the influence of the speed variation for each vehicle is suppressed. Moreover, you may make it display on a bulletin board the area where traffic congestion generate | occur | produced with a figure.

  Further, in the present invention, the communication means between the reading device 2 and the information processing device 4 is not limited to packet communication using a mobile phone communication network, but is a wireless LAN (Local Area Network), PHS (Personal Handy-phone System). , And other wireless communication such as satellite communication. Since the information transmission from the reading device 2 to the information processing device 4 is performed wirelessly, it is possible to reduce the cost of equipment for information communication such as when a cable is laid. The collection of passage information by the information processing device 4 from the reading device 2 may be performed by a request from the information processing device 4 to the reading device 2 separately from the periodic collection as described above.

  In the present invention, a camera may be provided in the reader 2 in order to make the driver more certain. In this case, the information processing device 4 transmits the vehicle identifier of the vehicle determined to be a speed violation to the reading device installed in the traveling direction of the vehicle. When the reading device receives the vehicle identifier, when the vehicle specified by the vehicle identifier passes, the reading device captures the face of the driver with the camera. Thereafter, the captured image is transmitted to the information processing apparatus 4. The information processing device 4 stores the captured image in the storage unit 41 together with the vehicle identifier of the vehicle that has violated the speed.

  In the present embodiment, the upper limit value is 1.2 times the reference speed and is indicated by the magnification relative to the reference speed. However, the upper limit value is simply set to a value obtained by adding a predetermined amount so as to be “reference speed + 10 km / h”. May be.

  Further, in the present embodiment, the case where the vehicle is a vehicle has been described as an object for measuring the speed, but the present invention may be applied to a train such as a bullet train. In this case, the reading device 2 is provided at the station. Further, instead of cracking down on speeding, the information processing device 4 distributes information on the excessive speed to the information terminal of the train that has exceeded the speed via the reading device 2. Moreover, it becomes possible to inform the following train of the delay of the previous train by the posting device.
