In step S603, the traffic control control client connects to the Internet through a data connection or the like, and reports the voting result including the positioning information and the traveling direction information to the background server.

Step S604, the background server performs classification statistics and processing judgment according to the voting situation:

Step S605, if the number of votes in one of the three directions of travel (left turn, straight turn, right turn) exceeds the vote in the other direction and exceeds a certain threshold (the threshold is a dynamic value, the measure is: this time If the driving section of the voting direction is the same as the driving direction of one of the other two sections of the intersection, the voting maximum of the other two sections of the intersection is the threshold of the voting. Reference value. If the threshold reference reference value is less than the current voting value, the threshold is set to 0; if the threshold reference reference value is greater than/equal to the current voting value, the threshold is equal to the threshold reference reference value), then S606, otherwise S607.

Step S606: The background server feeds back to the traffic light control center: the green time of extending the traveling direction of the road section and the red light time corresponding to the driving direction of other road sections having the same driving direction as the traveling direction, and shortening the red light of other traveling directions of the road section The time and the green time of other travel directions of other road sections feed back the processing result of “voting success, one lane priority release” to the corresponding voting client, and start its own timer. Before the timer expires, the background server no longer counts and processes the voting status of each intersection of the intersection; meanwhile, after the timer expires, the background server feeds back to the traffic control center: restore the traffic time of each section of the intersection.

In step S607, the background server feeds back to the corresponding voting client the processing result that the other road sections of the intersection are more congested and cannot be preferentially released, and starts its own timer. Before the timer expires, the background server no longer counts and processes the voting status of each road segment. After the timer expires, then continue to S604.

In step S608, if the number of votes in any two directions reaches the threshold in the three directions of travel (left turn, straight run, right turn), then S609, otherwise S607.

Step S609, the background server feeds back to the traffic light control center: extending the green time of the two traveling directions and the red light time corresponding to the driving direction of other road sections having the same driving direction as the traveling direction, and shortening the red of other traveling directions of the road section. The green time of the lamp time and other traveling directions of other road sections feeds back the processing result of "voting success, two lanes priority release" to the corresponding voting client, and starts its own timer. Before the timer expires, the background server no longer counts and processes the voting status of each intersection of the intersection; meanwhile, after the timer expires, the background server feeds back to the traffic control center: restore the traffic time of each section of the intersection.

In step S610, if the number of votes in the three directions reaches the threshold in the three directions of travel (left turn, straight turn, right turn), then S611, otherwise S607.

Step S611, the background server feeds back to the traffic light control center: extending the green light time of the three traveling directions of the intersection and the red light time corresponding to the driving direction of other road sections having the same driving direction as the traveling direction, and shortening the other traveling directions of the road section. The red light time and the green time of other travel directions of other road sections feed back the processing result of "voting success, three lanes priority release" to the corresponding voting client, and start its own timer. Before the timer expires, the background server no longer counts and processes the voting status of each intersection of the intersection; meanwhile, after the timer expires, the background server feeds back to the traffic control center: restore the traffic time of each section of the intersection.

In step S612, the traffic light control center receives the feedback from the background server, and sends the control command to the traffic light controller.

In step S613, the traffic light controller controls the change of the traffic light.
