A kind of traffic control method and traffic control system

Abstract

The invention discloses a traffic control method. The method comprises the steps: acquiring a vehicle flow image in a preset area; calculating a vehicle congestion degree according to the vehicle flowimage; adjusting the passing time of the current traffic light corresponding to the preset area according to the vehicle congestion degree; and when traffic congestion still occurs after adjustment,adjusting the passing time of other traffic lights except the current traffic light so as to reduce the number of vehicles entering the preset area. The invention also discloses a traffic control system which comprises an image acquisition part, a congestion degree calculation part, a first passing time adjustment part which is used for adjusting the passing time of the current traffic light according to the congestion degree of the vehicle, and a second passing time adjusting component which is used for adjusting the passing time of other traffic lights except the current traffic light to reduce the number of vehicles entering the preset area when the traffic congestion still occurs after adjustment. According to the traffic control method and system provided by the invention, congestioncan be relieved, road conditions can be improved, and unmanned and intelligent traffic management can be realized.

Description

technical field [0001] The invention belongs to the technical field of traffic control, in particular to a traffic control method and a traffic control system. Background technique [0002] With the development of smart city technology, the traffic system has also been given higher requirements, such as: how to find out whether the road is congested, and relieve the congested road condition without command; how to realize unmanned remote traffic control management, When there is congestion in a certain monitoring area, can the vehicle input flow in this area be adjusted to alleviate congestion and so on. In view of the above problems, smart transportation came into being, but there are still many difficulties in the process of realizing smart transportation. [0003] The current traffic light system has the following problems: the passing time cannot be dynamically adjusted according to the road condition information; when road congestion occurs, the traffic light system do...

AI Technical Summary

Problems solved by technology

[0003] The current traffic light system has the following problems: the passing time cannot be dynamically adjusted according to the road condition information; when road congestion occurs, the traffic light system does not play an effective role in alleviating, and human intervention is required; each traffic light is relatively independent and does not form an interrelated system. System scheduling, so it is impossible to monitor the flow of cars as a whole and adjust and control traffic conditions
