Traffic control apparatus, traffic control system, traffic control method, and non-transitory computer recording medium
A control part of a traffic control apparatus receives from a car-mounted device of one vehicle among a plurality of vehicles through a communicating part a projected time of arrival of that one vehicle at a destination and, if so, judges if there is a simultaneously arriving vehicle with the same desired drop-off position at the destination as the one vehicle and with the projected time of arrival at the destination in the same time frame from among the plurality of vehicles and, if there is a simultaneously arriving vehicle, determines vehicle stopping priorities at the desired drop-off position between the one vehicle and the simultaneously arriving vehicle based on information relating to the passengers in the one vehicle and the simultaneously arriving vehicle to be dropped off at the destination.
1. A traffic control apparatus comprising: a communication circuit configured to be able to communicate with car-mounted devices mounted in a plurality of vehicles controlled to be automatically driven; and a processor configured to: receive from the car-mounted device of one vehicle among the plurality of vehicles through the communication circuit, a projected time of arrival of the one vehicle at a destination within a drop-off area divided into a plurality of sections, each section is assigned a priority number; judge when, among the plurality of vehicles, there is a simultaneously arriving vehicle with a same desired drop-off position at the destination as the one vehicle and with the projected time of arrival at the destination at a same time frame; and, when there is a simultaneously arriving vehicle, determine vehicle stopping priorities at the desired drop-off position between the one vehicle and the simultaneously arriving vehicle based on information relating to passengers in the one vehicle and the simultaneously arriving vehicle to be dropped off at the destination, set stopping positions of the one vehicle and the simultaneously arriving vehicle within different sections of the drop-off area based on the vehicle stopping priorities and the priority numbers of the sections of the drop-off area, and send the stopping positions to the one vehicle and the simultaneously arriving vehicle to cause the one vehicle and the simultaneously arriving vehicle to stop at the stopping positions.
2. The traffic control apparatus according to claim 1 , wherein
the processor is further configured to:
determine stopping positions of the one vehicle and the simultaneously arriving vehicle based on the vehicle stopping priorities; and
send the stopping positions through the communicating part to the car-mounted devices of the one vehicle and the simultaneously arriving vehicle.
3. The traffic control apparatus according to claim 2 , wherein
the processor is further configured to make the stopping position of the vehicle with a higher vehicle stopping priority in the one vehicle and the simultaneously arriving vehicle the desired drop-off position.
4. The traffic control apparatus according to claim 1 , wherein
the information relating to the passengers of the one vehicle and the simultaneously arriving vehicle is age, any pregnancy, any accompanying infants or toddlers, any disability, a class of disability, any sickness, and a severity of sickness.
5. A traffic control system comprising: car-mounted devices mounted in a plurality of vehicles which are controlled to be automatically driven; and a server connected to be able to communicate with the car-mounted devices through a network, wherein each car-mounted device includes a processor configured to: periodically calculate a projected time of arrival of a vehicle at a drop-off point within a drop-off area divided into a plurality of sections, each section is assigned a priority number; and periodically transmit, to the server, position information showing a current location of the vehicle in which the car-mounted device is mounted while the vehicle is being driven and the projected time of arrival at the drop-off point, and the server is configured to: receive the position information and the projected time of arrival from each car-mounted device; search through the projected time of arrival of the plurality of vehicles to determine when there are two or more simultaneously arriving vehicles with a same desired drop-off point and a time of arrival with a same time frame; when there are two or more simultaneously arriving vehicles, determine vehicle stopping priorities at the desired drop-off position between the two or more simultaneously arriving vehicles based on information relating to passengers in the two or more simultaneously arriving vehicles; set stopping positions of the simultaneously arriving vehicles within different sections of the drop-off area based on the vehicle stopping priorities and the priority numbers of the sections of the drop-off area; and send the stopping positions to the simultaneously arriving vehicles to cause the simultaneously arriving vehicles to stop at the stopping positions.
6. A traffic control method comprising: receiving, through a communication circuit configured to be able to communicate with car-mounted devices mounted in a plurality of vehicles which are controlled to be automatically driven from a car-mounted device of one vehicle among the plurality of the vehicles, a projected time of arrival of the one vehicle at a destination within a drop-off area divided into a plurality of sections, each section is assigned a priority number; judging when, among the plurality of vehicles, there is a simultaneously arriving vehicle with a same desired drop-off position at the destination as the one vehicle and with the projected time of arrival at the destination in a same time frame; and when there is a simultaneously arriving vehicle, determining vehicle stopping priorities at the desired drop-off position between the one vehicle and the simultaneously arriving vehicle based on information relating to passengers in the one vehicle and the simultaneously arriving vehicle to be dropped off at the destination, setting stopping positions of the one vehicle and the simultaneously arriving vehicle in different sections of the drop-off area based on the vehicle stopping priorities and the priority numbers of the sections of the drop-off area, and sending the stopping positions to the one vehicle and the simultaneously arriving vehicle to cause the one vehicle and the simultaneously arriving vehicle to stop at the stopping positions.
7. A non-transitory computer recording medium including a computer program for traffic control use for making a computer: receive, through a communication circuit configured to be able to communicate with car-mounted devices mounted in a plurality of vehicles which are controlled to be automatically driven from a car-mounted device of one vehicle among the plurality of the vehicles, a projected time of arrival of the one vehicle at a destination within a drop-off area divided into a plurality of sections, each section is assigned a priority number; judge when, among the plurality of vehicles, there is a simultaneously arriving vehicle with a same desired drop-off position at the destination as the one vehicle and with the projected time of arrival at the destination in a same time frame; and when there is a simultaneously arriving vehicle, determine vehicle stopping priorities at the desired drop-off position between the one vehicle and the simultaneously arriving vehicle based on information relating to passengers in the one vehicle and the simultaneously arriving vehicle to be dropped off at the destination, set stopping positions of the one vehicle and the simultaneously arriving vehicle within different sections of the drop-off area based on the vehicle stopping priorities and the priority numbers of the sections of the drop-off area, and send the stopping positions to the one vehicle and the simultaneously arriving vehicle to cause the one vehicle and the simultaneously arriving vehicle to stop at the stopping positions.
