In the following embodiments, the same portions are denoted by the same reference numerals, and redundant description is omitted.

[1. Example of calculation process)
First, an example of calculation processing according to the embodiment will be described with reference to FIG. FIG. 1 is a diagram illustrating an example of a calculation process according to the embodiment. FIG. 1 shows an example in which the calculation device 100 performs a process of calculating an actual speed on a road that the user has traveled. More specifically, the calculation device 100 statistically processes the information acquired from the user terminal 10 used by the user, whereby the speed at which a plurality of users actually travel on the road on which the user has traveled (hereinafter, “ Calculated as “operation speed”. That is, the calculation apparatus 100 calculates what speed the actual road operation is performed by the processing described below.

  The calculation device 100 illustrated in FIG. 1 acquires the transition of the position of the user terminal 10 that is a terminal device used by the user, and based on the acquired transition of the position and time information at each position where the user terminal 10 has transitioned. This is an information processing device that calculates the operation speed on the road on which the user passes. For example, the calculation device 100 is realized by a server device that can communicate with the user terminal 10 via a network (for example, the Internet).

  A user terminal 10 shown in FIG. 1 is an information processing terminal used by a user. For example, the user terminal 10 is realized by a smartphone, a tablet terminal, or the like. In the example of FIG. 1, it is assumed that the user terminal 10 is used by the user U01. In the following description, the user terminal 10 may be referred to as the user U01. Further, in the example of FIG. 1, only one user terminal 10 or one user U01 is illustrated for simplicity of explanation, but actually, the calculation device 100 has a significant number of statistically significant values. It is assumed that various types of information are acquired from the user terminal 10 or the user U01.

  In the example of FIG. 1, it is assumed that the user terminal 10 is installed with a program capable of acquiring location information of the own device, route information indicating a route of movement, and the like. For example, an application for realizing a car navigation system (hereinafter referred to as “car navigation application”) is installed and executed on the user terminal 10. The user terminal 10 acquires road information and map information via the car navigation application according to the embodiment. Further, the user terminal 10 can acquire position information, which is information indicating a position where the own device exists, using, for example, GPS (Global Positioning System). Then, the user terminal 10 continuously transmits the acquired position information to the calculation device 100 in accordance with the function of the car navigation application or a request received from the calculation device 100. In addition, the user terminal 10 transmits time information indicating the time when the position information is acquired to the calculation apparatus 100 together with the position information.

  Here, the road information used in the car navigation application or the like may include information related to a speed specified in advance. The speed designated in advance refers to, for example, a designated speed set by a public organization. The designated speed is designated for each road or for each predetermined section of the road.

  However, it is difficult to grasp detailed information such as the actual operation status of the road, that is, at what speed the user is actually moving on the road. This is because the road operation is not necessarily performed at a speed close to the designated speed, but varies depending on the ease of travel, the number of traffic lights, the traffic of passers-by, and the like. If the actual road speed can be grasped, for example, the time to the destination can be measured with high accuracy by the car navigation application, or useful information is provided to the government that investigates the driving situation. I can do it.

  Therefore, the calculation device 100 according to the embodiment calculates the actual operation speed on the road on which the user passes by performing the processing described below. Thereby, the calculation apparatus 100 may calculate the difference between the designated speed and the actual driving speed on each road, or extract information such as how much the user can actually travel. it can. Hereinafter, the calculation process executed by the calculation apparatus 100 will be specifically described along the flow with reference to FIG.

  In the example of FIG. 1, it is assumed that the user U01 is driving a car while activating a car navigation application executed on the user terminal 10. The user terminal 10 continuously transmits information related to the movement of the user U01 to the calculation device 100 (step S01).

  For example, the user terminal 10 may change the position of the user U01 based on information related to a road on which the user U01 passes, position information of the user U01 (that is, position information of the user terminal 10), and time corresponding to each position. Information (specifically, time when the user U01 is located at a predetermined point) and the like are transmitted to the calculation device 100.

  The calculation device 100 acquires information related to movement from the user terminal 10. And the calculation apparatus 100 calculates the actual speed (operation speed) for every road, when the statistically significant number (for example, 1000 or 2000) information for every road is totaled (step S02). Although details will be described later, the calculation device 100 calculates the operation speed on the road on which the user passes based on the transition of the position of the user terminal 10 and the time information at each position where the user terminal 10 has transitioned.

  Subsequently, the calculation device 100 maps the calculated operation speed to each road included in the road information (step S03). Furthermore, the calculation device 100 generates map information indicating the difference between the designated speed and the actual speed (operation speed) (step S04).

  Thereafter, the calculation device 100 provides information such as the calculated speed to the user U01 in accordance with a request from the user U01, for example (step S05). The calculation apparatus 100 provides information to the user U01 via, for example, a car navigation application. Specifically, the calculation device 100 provides information indicating a difference between the current speed of the user U01 and the operation speed on the road on the road on which the user U01 is traveling. Furthermore, the calculation device 100 recommends that the user U01 decelerate or accelerate when the current speed of the user U01 is far from the operation speed, or that the user travels on another road through the car navigation application. You may provide advice on how to get there early.

  In addition, when the user U01 specifies a destination in the car navigation application, the calculation device 100 may provide time information predicted to reach the destination based on the calculated operation speed. In addition, the calculation device 100 provides the user U01 with map information indicating the difference between the designated speed and the operation speed (for example, map information in a form like a heat map in which a road with a large difference is displayed in color). Also good.

  Here, the calculation process executed by the calculation apparatus 100 will be specifically described with reference to a schematic diagram 80. For example, it is assumed that the user U01 has moved through the point 91, the point 93, the point 95, and the point 97. At this time, the calculation device 100 acquires position information indicating that the user U01 is located at each point, and time information at each point.

  Specifically, the calculation device 100 acquires that the time information when the user U01 is located at the point 91 is “12:00”. In addition, the time information when the user U01 is located at the point 93 is “12:30” and the time information when the user U01 is located at the point 95 is “12:50”. It is acquired that the time information when the user U01 is located at the point 97 is “13:10”.

  Moreover, the calculation apparatus 100 acquires information such as a designated speed of a road including each point and a distance between the points. Specifically, the calculation device 100 acquires information that the designated speed of the road including the point 91 and the point 93 is “60 km / h (km / h)”. Further, the calculation device 100 acquires information that the designated speed of the road including the point 93 and the point 95 is “40 km / h”. Further, the calculation device 100 acquires information that the designated speed of the road including the point 95 and the point 97 is “50 km / h”. Further, the calculation device 100 has a distance between the point 91 and the point 93 of “35 km”, a distance between the point 93 and the point 95 of “10 km”, and the distance between the point 95 and the point 97 is Information that the distance is “25 km” is acquired.

  The calculation apparatus 100 calculates the speed at which the user U01 actually moved on the road based on the acquired information. Specifically, the calculation device 100 spends “30 minutes” for the user U01 to move from the point 91 to the point 93, and the distance is “35 km”. The actual speed moved to the point 93 is calculated as “70 km”. Similarly, the calculation device 100 calculates the actual speed at which the user U01 has moved from the point 93 to the point 95 as “30 km”, and calculates the actual speed at which the user U01 has moved from the point 95 to the point 97 as “75 km”.

  The calculation device 100 adds up the operation speeds of the individual users calculated in this way. Then, the calculation device 100 calculates the operation speed for each road (more specifically, for each section connected by a point) when a statistically significant number of pieces of information are collected.

  In the above example, in order to simplify the description, an example in which the operation speed is obtained based on the transition of the position between two points on one road and the time information has been shown. You may make it total the information in. In addition, the calculation device 100 may set the points 91, 93, etc. at random, or breaks according to traffic regulations (for example, intersections, points where designated speeds are switched, administrative divisions (borders of cities and wards) Etc.) etc.). Moreover, the calculation apparatus 100 does not necessarily need to acquire the information of the point common to all the users. That is, since the calculation device 100 can obtain the user's moving speed by acquiring the transition of the position between any two points and the time information as long as they are on a common road, the information to be aggregated is It does not necessarily need to be common point information.

  Moreover, when the information which shows a peculiar situation is included among the totaled information, the calculation apparatus 100 may exclude the information which shows a peculiar situation, for example by providing a predetermined threshold value. For example, a user who has stopped by the road for some reason, a user who has made a U-turn between points, or the like may calculate a speed that is significantly different from other users. In such a case, for example, the calculation device 100 adopts a method such as excluding information indicating a speed exceeding a predetermined threshold value from the average value from the aggregation, thereby obtaining an operation speed that excludes information indicating a specific situation. Can be calculated.

  As described above, the calculation device 100 according to the embodiment acquires the transition of the position of the user terminal 10 used by the user U01. And the calculation apparatus 100 calculates the operation speed in the road which the user U01 passed based on the transition of the acquired position, and the time information in each position where the user terminal 10 changed.

  That is, the calculation device 100 calculates the speed based on the position transition and the time information regardless of the current speed detected by the function of the host vehicle, so that the user can actually move the road at any speed. Is calculated. Then, the calculation device 100 can calculate the speed at which the operation on the actual “road” is performed by statistically calculating the speed of each user for each road. Thereby, the calculation device 100 provides, for example, map information indicating a difference between the designated speed and the operation speed to a public institution, performs car navigation based on the operation speed, and performs driving operation based on the operation speed. Various uses such as giving advice to the user are possible. For example, when the user travels on a road whose operation speed is significantly higher than a specified speed, the calculation device 100 can give advice that prompts the user to decelerate on the road. For roads for which the designated speed is not explicitly set, the calculation device 100 may read, for example, a speed determined based on a law (legal speed) as the designated speed.

  In the example of FIG. 1, the calculation apparatus 100 indicates that the position information detected by the user terminal 10 is acquired from the user terminal 10. However, the calculation apparatus 100 may acquire information related to movement such as position information by crawling the user terminal 10 every predetermined time without being transmitted from the user terminal 10. The calculation device 100 is not limited to the car navigation application, but is installed on the user terminal 10 other than the car navigation application (for example, a portal site application that provides a comprehensive web service, the current location and map information of the user U01, The position information may be continuously acquired via a map application that displays the information.

The user terminal 10 also includes a wearable device that is a glasses-type or watch-type information processing terminal. Furthermore, the user terminal 10 may include various smart devices as long as the user terminal 10 has an information processing function for acquiring position information. For example, the user terminal 10 may include a smart home appliance such as a TV (television), a refrigerator, and a vacuum cleaner, a smart vehicle such as an automobile, a drone, and a home robot.

  The user terminal 10 acquires and stores the position information of the own device according to the operation by the user and the function of the user terminal 10. For example, the user terminal 10 acquires position information by communicating with an external system such as the GPS described above. Then, the user terminal 10 transmits the acquired position information, time information corresponding to the time when the position information is acquired, and the like to the calculation device 100.

For example, the acquisition unit 131 acquires the transition of the position of the user terminal 10 from the user terminal 10 used by the user. Specifically, the acquisition unit 131 acquires, as position transition, position information detected by the user terminal 10 and a plurality of position information indicating the movement of the user terminal 10. The acquisition unit 131 acquires time information indicating the time when the position information is detected together with the position information.

  Moreover, the acquisition part 131 acquires the information regarding a road. For example, the acquisition unit 131 acquires road information including information on a designated speed designated in advance for each road. For example, the acquisition unit 131 may acquire road information by receiving an input from the administrator of the calculation apparatus 100, or may acquire road information from an external server that provides road information or existing map information. Good.

  Moreover, the acquisition part 131 may acquire the transition of the position of the user terminal 10 for every time slot | zone or every day of the week as position information to acquire. That is, since it is assumed that the road operating speed differs for each time zone or day of the week, the acquisition unit 131 acquires the transition of the position for each time zone or for each day of the week, and for each time zone or for each day of the week. Log data may be aggregated.

  Note that the acquisition unit 131 does not necessarily acquire position information at the same time as the time when the user terminal 10 acquires position information. That is, the acquisition unit 131 may acquire position information and time information stored in the storage unit 16 of the user terminal 10 at an arbitrary timing, instead of acquiring position information in real time.

  The acquisition unit 131 stores the acquired information in the storage unit 120 as appropriate. For example, when the acquisition unit 131 acquires information related to movement, the acquisition unit 131 stores the acquired information in the movement information storage unit 122. The acquisition unit 131 may send the acquired information to each processing unit such as the calculation unit 132.

(About the calculation unit 132)
The calculation unit 132 calculates the operation speed on the road that the user has traveled based on the transition of the position acquired by the acquisition unit 131 and the time information at each position where the user terminal 10 has shifted. Specifically, the calculation unit 132 calculates the estimated speed in each log data based on the transition of the position in each log data and the time information in each position, and statistics the calculated estimated speed, thereby operating. Calculate the speed.

  Further, the calculation unit 132 may calculate a difference between a designated speed of a predetermined road and an operation speed calculated on the predetermined road. Thereby, the calculation unit 132 can obtain a difference between the speed designated for the road by a public institution or the like and the speed at which the user is actually moving.

  In addition, the calculation unit 132 may calculate the speed of the predetermined user on the road on which the predetermined user passes, and may calculate the difference between the operation speed on the road on which the user passes and the speed of the user. . For example, the calculation unit 132 calculates the transition of the position of the user and the time information in real time via a car navigation application or the like, and calculates a difference between the operation speed calculated in advance. The providing unit 134 to be described later may provide the calculated difference to the user, and may provide advice on the user's travel, for example.

  As a specific calculation method, the calculation unit 132 includes position information indicating that the user terminal 10 is located at a first point on the road and a second point different from the first point, and the user terminal 10 Based on the time information at the time point located at the first point and the time information at the time point located at the second point, the operation speed on the road is calculated. That is, the calculation unit 132 calculates the operation speed on the road based on the position information and the time information detected at any two points on one road on which the common specified speed is specified.

  Note that the calculation unit 132 includes a predetermined position on the road and position information indicating that the user terminal 10 is located on an administrative boundary (for example, a municipal boundary) on the road, and the user terminal 10 The operation speed on the road may be calculated based on the time information at the position and the time information at the time of the administrative boundary. Thereby, since the calculation part 132 can calculate the operation speed within the administrative boundary, not the operation speed across the administrative boundary, for example, when providing information on the operating speed to a public institution It is possible to provide flexible information according to the mode required by public institutions.

  Moreover, the calculation part 132 may calculate the operation speed in a road for every time slot | zone or every day of the week. As described above, since the operation speed of the road is assumed to change every time zone or every day of the week, the calculation unit 132 calculates the operation speed every time zone or every day of the week. Useful information that matches reality can be obtained.

The speed of the terminal 10 can be estimated. In addition to the gyro sensor, the calculation apparatus 100 may acquire sensor information of a direction sensor or an acceleration sensor, and calculate a velocity vector from the acquired data value, thereby estimating the moving direction and speed of the user. . In addition to the gyro sensor, the calculation device 100 may estimate the direction using, for example, a geomagnetic sensor.

  Thus, the calculation apparatus 100 may acquire operation information detected by a sensor included in the user terminal 10 and calculate an operation speed on a road on which the user has traveled based on the acquired operation information.

  That is, the calculation device 100 can measure and calculate the speed and traveling direction of the user based on not only information such as GPS but also various information, so that calculation processing can be performed more flexibly.

May be.

[6-2. (Aggregation by user attribute)
The calculation device 100 may total the log data for each user attribute and calculate the operation speed for each user attribute. That is, since it is assumed that the road operating speed varies depending on the gender, age, place of residence, and the like of the user, the calculation device 100 may perform a calculation process in consideration of the difference.

  For example, the calculation device 100 identifies the user attribute based on cookie information of the user who has logged into the car navigation application. And the calculation apparatus 100 totals log data for every attribute of a user. For example, the calculation device 100 may store log data for each gender or age group (for example, 20s and 30s as one segment and 40s and 50s as one segment). Tally.

Thereby, the calculation apparatus 100 can extract useful information, such as what kind of attribute the user actually has a tendency to perform, with high accuracy.

[6-3. (Total by weather)
The calculation device 100 may total the log data for each different weather and calculate the operation speed for each weather. That is, since it is assumed that the road operating speed varies depending on weather, temperature, humidity, and the like, the calculation device 100 may perform a calculation process in consideration of such differences.

  For example, the calculation apparatus 100 accesses a predetermined external server that provides weather information, and associates information obtained by collecting log data from the user terminal 10 with weather information such as weather, temperature, and humidity. And the calculation apparatus 100 totals log data for every different weather information. For example, the calculation apparatus 100 may count sunny days and rainy days as different log data, or may count days with higher and lower temperatures as different log data compared to the average temperature throughout the year. May be. And the calculation apparatus 100 calculates the operation speed for every different weather information.

However, the user terminal 10 does not necessarily need to include all the processing units illustrated in FIG. For example, the user terminal 10 may not necessarily include the input unit 12 and the display unit 13. Further, the user terminal 10 may be separated into two or more devices to realize the configuration illustrated in FIG. For example, the user terminal 10 may be realized by two or more devices having a configuration in which a detection device having at least the detection unit 14 and the acquisition unit 152 and a communication device having at least the communication unit 11 are separated. . For example, the user terminal 10 may be realized by a watch-type IoT (Internet of Things) device having a function of acquiring position information, and an information processing terminal that transmits the acquired information to the calculation device 100.

Here, the calculation device 100 is not limited to the GPS or the like, and any information may be used as long as it is information that can estimate the position of the user or the user terminal 10. For example, the calculation device 100 may acquire information that the user is moving on the road when the user terminal 10 is connected to an access point installed on or near the road.

[6-7. (Calculation of individual user terminal speed)
In the said embodiment, the example which the calculation apparatus 100 calculates the estimated speed of each user terminal 10 based on the positional information and time information transmitted from each user terminal 10 was shown. Here, the estimated speed of each user terminal 10 may be calculated by each user terminal 10 instead of being calculated by the calculation device 100.

  That is, the user terminal 10 calculates the estimated speed on each road based on the position information (position transition) detected by itself and the time information. Then, the user terminal 10 transmits the calculated speed information to the calculation device 100. The calculation device 100 calculates the operation speed of each road based on the speed information calculated by the user terminal 10 and the position information of the user terminal 10. For example, the calculation device 100 stores the road information that the user terminal 10 has passed, the time information, and the speed of the user terminal 10 estimated at that time in the storage unit 120 in association with each other. And the calculation apparatus 100 calculates the operation speed in each road, when a statistically significant number of information is acquired. Thereby, since the calculation apparatus 100 can omit the process of calculating the estimated speed of each user terminal 10, the processing load can be reduced. Moreover, the process which calculates the operation speed in each road may be performed by arbitrary user terminals 10 based on the estimated speed acquired from each user terminal 10.
