Intelligent traffic light control system

Abstract

The invention relates to an intelligent traffic light control system, which comprises a microprocessor which is used to control switching actions of traffic lights, wherein the microprocessor is provided with a manual input device, a forced switching device and an intelligent detecting device, wherein the intelligent detecting device comprises a panoramic camera and an intelligent controller, the panoramic camera is used to obtain real time video images of road conditions on each direction, the intelligent controller is used to adopt the video images which are obtained by the camera through a video capture card and to recognize stopping vehicles on each road, the stopping and queuing distance of the vehicles is calculated, recognition and calculation are carried out according to the stopping and queuing distance of the vehicles on each road, an instruction of modifying a traffic light control parameter is sent by the microprocessor according to prearranged procedures, and the microprocessor receives the instruction and modifies the traffic light control parameter. The control system automatically adjusts the traffic light control parameter according to the traffic flow changes on different directions to improve the traffic efficiency of intersections and to realize optimum control to intersection traffic.

Description

technical field [0001] The invention relates to an intelligent traffic light control system, which is mainly used for traffic light control at traffic road intersections. technical background [0002] The existing traffic light control system is set in the cabinet located on the side of the traffic light road, and the action of the traffic light switch is controlled by the microprocessor to realize the sequential conversion of the traffic light. Control parameters such as traffic light switching sequence and switching time, realize the direct control of traffic lights by people through the forced switch device. The defect of this technology is that the control parameters cannot be automatically adjusted according to the traffic flow in each direction. Therefore, after manually setting the control parameters, No matter how the traffic situation changes in each time period, it cannot actively adapt to the traffic situation, so that the traffic control at the intersection canno...
