selecting a traffic signal machine that performs signal control for stopping the vehicle from among control target traffic signal machines,
wherein the processor selects a traffic signal machine that is located in a traveling direction of the vehicle and that may eliminate traffic jam by the signal control for stopping the vehicle, and
wherein the processor determines whether or not to stop the vehicle based on past behavior of the vehicle detected by the sensor or sensors.
2. The traffic signal control apparatus according to claim 1 , wherein, in a case where a vehicle waiting to turn right stays at an intersection where the traffic signal is installed, the processor selects the traffic signal machine at the intersection as the traffic signal machine that performs the signal control for stopping the vehicle.
3. The traffic signal control apparatus according to claim 1 , wherein, in case where there is a vehicle or pedestrian waiting for signal change at a location where the traffic signal is installed, the processor selects the traffic signal machine as the traffic signal machine that performs the signal control for stopping the vehicle.
4. The traffic signal control apparatus according to claim 1 , wherein the processor selects a traffic signal machine or machines located one or more ahead in the traveling direction of the vehicle as a candidate or candidates of the traffic signal machine that performs the signal control for stopping the vehicle.
5. The traffic signal control apparatus according to claim 1 , wherein the processor selects a vehicle that disregards a traffic signal or signals or exceeds a speed limit as a stop target.
6. The traffic signal control apparatus according to claim 1 , wherein the processor selects a vehicle entering an intersection during signaling of a yellow signal as a stop target.
7. The traffic signal control apparatus according to claim 1 , wherein the processor stays the signal control for stopping the vehicle in a case where the speed of the vehicle is a predetermined value or more.
8. A control method of a traffic signal machine performed by a computer and comprising:
determining whether or not to stop a vehicle based on behavior of the vehicle entering a predetermined intersection; and
selecting a traffic signal machine or machines that are located in a traveling direction of the vehicle and that may eliminate traffic jam by the signal control for stopping the vehicle as a traffic signal machine or machines that perform signal control for stopping the vehicle from among control target traffic signal machines,
wherein determining whether or not to stop the vehicle comprises determining whether or not to stop the vehicle based on past behavior of the vehicle detected by the sensor or sensors.
9. A non-transitory program recording medium storing a program, wherein the program causes a computer to execute:
determining whether or not to stop a vehicle based on behavior of the vehicle entering a predetermined intersection; and
selecting a traffic signal machine or machines that are located in a traveling direction of the vehicle and that may eliminate traffic jam by the signal control for stopping the vehicle as a traffic signal machine or machines that perform signal control for stopping the vehicle from among control target traffic signal machines,
wherein determining whether or not to stop the vehicle includes determining whether or not to stop the vehicle based on past behavior of the vehicle detected by the sensor or sensors.
10. The control method according to claim 8 , wherein, in a case where a vehicle waiting to turn right stays at an intersection where the traffic signal is installed, further comprising selecting the traffic signal machine at the intersection as the traffic signal machine that performs the signal control for stopping the vehicle.
11. The control method according to claim 8 , wherein, in case where there is a vehicle or pedestrian waiting for signal change at a location where the traffic signal is installed, further comprising selecting the traffic signal machine as the traffic signal machine that performs the signal control for stopping the vehicle.
12. The control method according to claim 8 , wherein selecting a traffic signal machine or machines comprises selecting a traffic signal machine or machines located one or more ahead in the traveling direction of the vehicle as a candidate or candidates of the traffic signal machine that performs the signal control for stopping the vehicle.
13. The control method according to claim 8 , wherein selecting a traffic signal machine or machines comprises selecting a vehicle that disregards a traffic signal or signals or exceeds a speed limit as a stop target.
14. The control method according to claim 8 , wherein selecting a traffic signal machine or machines comprises selecting a vehicle entering an intersection during signaling of a yellow signal as a stop target.
15. The control method according to claim 8 , wherein the method comprises staying the signal control for stopping the vehicle in a case where the speed of the vehicle is a predetermined value or more.
16. The non-transitory program recording medium according to claim 9 , wherein in a case where a vehicle waiting to turn right stays at an intersection where the traffic signal is installed, the program causes a computer to execute selecting the traffic signal machine at the intersection as the traffic signal machine that performs the signal control for stopping the vehicle.
17. The non-transitory program recording medium according to claim 9 , wherein, in case where there is a vehicle or pedestrian waiting for signal change at a location where the traffic signal is installed, the program causes a computer to execute selecting the traffic signal machine as the traffic signal machine that performs the signal control for stopping the vehicle.
18. The non-transitory program recording medium according to claim 9 , wherein, the program causes a computer to execute selecting a traffic signal machine or machines located one or more ahead in the traveling direction of the vehicle as a candidate or candidates of the traffic signal machine that performs the signal control for stopping the vehicle.
19. The traffic signal control apparatus according to claim 1 , wherein the processor determines to not stop the vehicle, in case where the vehicle is an emergency vehicle.
