(How to identify supplementary information)
Hereinafter, a method for identifying supplementary information according to the first embodiment will be described with reference to the drawings. 2-5 is a figure which illustrates about the specific method of the supplementary information which concerns on 1st Embodiment.

(1) Roads that allow only pedestrian traffic (pedestrian roads)
Here, consider the case where the road 400 is a pedestrian road as shown in FIG. In such a case, the pedestrian 20 passes the road 400, but the vehicle 30 basically does not pass the road 400. The identifying unit 150 identifies the pedestrian-only road based on the movement history of the pedestrian 20 and the movement history of the vehicle 30 using such characteristics. Note that the pedestrian road includes not only a pedestrian road defined by the Road Traffic Law but also pedestrian heaven. For example, the specifying unit 150 specifies a pedestrian road according to the following procedure.

  First, the specifying unit 150 specifies a road (hereinafter, a determination target road) in which the change amount of the movement history of the vehicle 30 exceeds the change amount threshold between the comparison target time zone and the determination target time zone. The comparison target time zone and the determination target time zone satisfy the comparison condition.

  The comparison conditions are: (a) the time zone is the same, (b) the day of the week and the time zone are the same, (c) the date and the time zone are the same, (d) the date type (for example, weekday) / Holiday) and the same time zone.

  The change amount threshold value is, for example, a threshold value representing the change amount in%. The change amount threshold may be different for each determination target road. It is preferable that the change amount threshold is determined according to the number of vehicles 30 (traffic volume) passing through the determination target road. Specifically, the change amount threshold value of the determination target road with a small amount of traffic is higher than the change amount threshold value of the determination target road with a large amount of traffic.

  For example, the change amount threshold is set to 20% between the A intersection and the B intersection of the national highway x with a relatively large traffic volume, and between the B intersection and the C intersection of the national highway x with a relatively small traffic volume, The change amount threshold is set to 30%. Moreover, you may exclude from the determination target road about the road where traffic volume is remarkably small.

  Secondly, the specifying unit 150 determines whether or not the number of vehicles 30 (traffic volume) traveling on the determination target road is smaller than a first determination threshold (for example, “0”) in the determination target time zone. When the number of vehicles 30 (traffic volume) is smaller than the first determination threshold, the specifying unit 150 specifies supplementary information that the determination target road is a pedestrian-only road in the determination target time zone.

  Thus, supplemental information includes (a) a pedestrian road at a specific time zone, (b) a pedestrian road at a specific day of the week and a specific time zone, (c) at a specific date and a specific time zone. A pedestrian road, (d) a pedestrian road in a specific date type and a specific time zone.

(2) Roads where vehicle traffic is temporarily restricted (vehicle traffic regulation)
Here, as shown in FIG. 3, consider a case where the area traffic restriction is performed on the road 400. In such a case, the pedestrian 20 passes through the road 400, but the number of vehicles 30 passing through the road 400 is small. The specifying unit 150 uses such characteristics to specify the vehicle passage restricted road based on the movement history of the pedestrian 20 and the movement history of the vehicle 30. The vehicle passage restricted road is a road in which the passage of the vehicle 30 is temporarily restricted.

  1stly, the specific | specification part 150 has the variation | change_quantity of the movement history of the vehicle 30 exceeding a variation | change_quantity threshold value between a comparison object time slot | zone and a determination object time slot | zone similarly to the pedestrian exclusive road mentioned above. A road (hereinafter referred to as a determination target road) is specified.

  Secondly, the specifying unit 150 determines whether or not the number of vehicles 30 (traffic volume) traveling on the determination target road is smaller than the second determination threshold in the determination target time zone. When the number of vehicles 30 (traffic volume) is smaller than the second determination threshold, the specifying unit 150 specifies supplementary information that the determination target road is a vehicle passage restricted road in the determination target time zone.

  As described above, the supplemental information includes (a) a vehicle restricted road in a specific time zone, (b) a vehicle restricted road in a specific day of the week and a specific time zone, and (c) a specific date and a specific time zone. Vehicle traffic-restricted roads, (d) vehicle-restricted roads in specific date types and specific time zones, and the like.

(3) Pedestrian bridge where pedestrian crosses road Here, a case where a pedestrian bridge 500 is provided will be considered. In such a case, the moving speed of the vehicle 30 does not decrease at the position where the pedestrian bridge 500 is provided. In the area 510 and the area 520, the pedestrian 20 does not stop. At the position where the pedestrian bridge 500 is provided, the pedestrian 20 and the vehicle 30 pass at the same time. The identifying unit 150 identifies the pedestrian bridge based on the movement history of the pedestrian 20 and the movement history of the vehicle 30 using such characteristics.

(4) A pedestrian crossing where a pedestrian crosses a road.

  Here, consider a case where a pedestrian crossing 600 is provided. In such a case, the moving speed of the vehicle 30 decreases at the position where the pedestrian crossing 600 is provided. Alternatively, the vehicle 30 stops at a position where the pedestrian crossing 600 is provided. In the area 610 and the area 620, the pedestrian 20 stops. At the position where the crosswalk 600 is provided, the pedestrian 20 and the vehicle 30 do not pass at the same time. The identifying unit 150 identifies the pedestrian bridge based on the movement history of the pedestrian 20 and the movement history of the vehicle 30 using such characteristics.

(Function and effect)
In the first embodiment, the specifying unit 150 specifies supplementary information based on pedestrian position information and vehicle position information.
