Embodiment Construction
[0017] There are two control algorithm implementations:
[0018] One is that every car within the control range of the intersection sends a REQ message to the controller C.

After C receives the REQ message from the car, it will process it and Reply to the PMS message separately, any car that has sent the REQ message can only pass after receiving the PMS message, otherwise wait.
[0019] The other is to send a detection message to the front after a car enters the lane to determine whether there is a car waiting in front of it. If there is a car in front of it, it also keeps waiting after maintaining the front-rear relationship in the front car. If there is no car in front of it, then send a REQ message to controller C, and wait for a reply. In this scheme, cars can communicate with each other, and only the first car passing each time sends REQ to controller C, and the passing ...
