An intelligent traffic light control system and its implementation method

Abstract

The invention discloses an intelligent traffic light control system and an implementing method thereof. The system is composed of a central processing unit and field control systems which are same in structure and arranged at every intersection; each field control system comprises an image collector, an image processor, a node controller, a traffic light display module and a communication module. The implementing method of the control system comprises the steps of: dividing one day into a peak traffic hour, an off-peak period, and a trough period according to changes of people and traffic flow, and if the weighted flow of a certain lane is continuously the maximum one for j-th times, automatically adjusting time lengths of the traffic lights based on cooperative control on the traffic lights at multiple intersections. The intelligent traffic light control system and the implementing method thereof can effectively enhance passing efficiencies and traffic intelligent levels of urban roads, and has actual application and promotional values.

Description

technical field [0001] The invention relates to an intelligent traffic light control system and a realization method. It belongs to the field of intelligent transportation technology. Background technique [0002] With the development of economy and society, the number of urban car ownership is increasing. How to improve the efficiency of automobile traffic and reduce the occurrence of traffic congestion as much as possible is an important problem that needs to be solved urgently. At present, the running time of traffic lights in all directions at each intersection of urban roads is usually controlled by timing. Timing control does not take into account the real-time changes in the traffic flow at the crossing. In some time periods, there may be a small amount of traffic in the lane with a green light, while a large amount of traffic in the lane with a red light. The use of timing control will cause the "empty waiting" phenomenon of vehicles or pedestrians, which reduces ...

AI Technical Summary

Problems solved by technology

This utility model does not take into account the changes in the flow of pedestrians, battery cars, bicycles, etc., and adopts the same control strategy in the peak period, non-peak period, and trough period, so it is not convenient to realize the intelligent control of traffic lights

[0004] In the existing technology, the traffic peak period, off-peak period, and trough period have not been determined according to the change of people and vehicle flow, and on the basis of coordinated control of traffic lights at multiple intersections, intelligent and non-frequent adjustment of traffic lights has been realized. systems and methods
