Abstract

A route control device includes a control unit that sets an angle of a guideway for guiding a wheelchair user with respect to a roadway in accordance with a length of a waiting time for which a vehicle traveling on the roadway is kept waiting, when the wheelchair user who is about to cross the roadway is detected, and performs a control of displaying a pedestrian crossing including the guideway on the roadway.

Claims (24)

1. A route control device comprising a control unit that sets an angle of a guideway for guiding a wheelchair user with respect to a roadway in accordance with a length of a waiting time for which a vehicle traveling on the roadway is kept waiting, when the wheelchair user who is about to cross the roadway is detected, and performs a control of displaying a pedestrian crossing including the guideway on the roadway.

2. The route control device according to claim 1 , wherein the control unit sets the angle in accordance with a moving speed of the wheelchair user.

3. The route control device according to claim 1 , wherein the control unit sets the angle further in accordance with a width of the roadway.

4. The route control device according to claim 1 , wherein when the roadway is located on a right side with respect to a traveling direction of the wheelchair user, the control unit sets the angle within a range of more than 0° to 90° or less clockwise with an azimuth angle of the traveling direction set to 0°.

5. The route control device according to claim 1 , wherein when the roadway is located on a left side with respect to a traveling direction of the wheelchair user, the control unit sets the angle within a range of more than 0° to 90° or less counterclockwise with an azimuth angle of the traveling direction set to 0°.

6. The route control device according to claim 1 , wherein the control unit performs a control of displaying the pedestrian crossing in a shape of the guideway.

7. The route control device according to claim 1 , wherein the control unit defines an area in which the guideway serves as a diagonal line and performs a control of displaying the pedestrian crossing in a shape of the defined area.

8. The route control device according to claim 7 , wherein the control unit performs a control of displaying a shape of the guideway by superimposing the shape of the guideway on the pedestrian crossing.

9. The route control device according to claim 1 , wherein the control unit performs the control of displaying the pedestrian crossing including the guideway by superimposing the pedestrian crossing including the guideway on a pedestrian crossing provided to extend along a direction orthogonal to the roadway.

10. The route control device according to claim 1 , wherein the control unit provides one or more checkpoints on the guideway and notifies, for each of the one or more checkpoints, the wheelchair user of a timing at which the wheelchair user is required to pass the each of the one or more checkpoints for completing crossing the roadway within the waiting time.

11. The route control device according to claim 1 , wherein the control unit notifies the wheelchair user of a display position of the pedestrian crossing including the guideway before displaying the pedestrian crossing including the guideway.

12. A route control method comprising:

setting, by a route control device, an angle of a guideway for guiding a wheelchair user with respect to a roadway in accordance with a length of a waiting time for which a vehicle traveling on the roadway is kept waiting, when the wheelchair user who is about to cross the roadway is detected; and

performing, by the route control device, a control of displaying the pedestrian crossing including the guideway on the roadway.

13. The route control method according to claim 12 , wherein setting the angle includes setting the angle further in accordance with a moving speed of the wheelchair user, by the route control device.

14. The route control method according to claim 12 , wherein setting the angle includes setting the angle further in accordance with a width of the roadway, by the route control device.

15. The route control method according to claim 12 , wherein setting the angle includes setting, by the route control device, the angle within a range of more than 0° and 90° or less clockwise with an azimuth angle of a traveling direction set to 0°, when the roadway is located on a right side with respect to the traveling direction of the wheelchair user.

16. The route control method according to claim 12 , wherein setting the angle includes setting, by the route control device, the angle within a range of more than 0° and 90° or less counterclockwise with an azimuth angle of a traveling direction set to 0°, when the roadway is located on a left side with respect to the traveling direction of the wheelchair user.

17. The route control method according to claim 12 , wherein displaying the pedestrian crossing including the guideway on the roadway includes displaying the pedestrian crossing in a shape of the guideway.

18. The route control method according to claim 12 , wherein displaying the pedestrian crossing including the guideway on the roadway includes defining an area in which the guideway serves as a diagonal line and displaying the pedestrian crossing in a shape of the defined area.

19. The route control method according to claim 12 , wherein displaying the pedestrian crossing including the guideway on the roadway includes displaying the pedestrian crossing including the guideway by superimposing the pedestrian crossing including the guideway on a pedestrian crossing provided to extend along a direction orthogonal to the roadway.

20. The route control method according to claim 12 , comprising:

providing, by the route control device, one or more checkpoints on the guideway; and

notifying, for each of the one or more checkpoints, the wheelchair user of a timing at which the wheelchair user is required to pass the each of the one or more checkpoints for completing crossing the roadway within the waiting time, by the route control device.
