Regional controlled intelligent traffic light control system

Abstract

The invention relates to a regional controlled intelligent traffic light control system, comprising a regional controlled traffic control center and a plurality of crossing control systems communicated with the regional controlled traffic control center; wherein the crossing control system comprises a microprocessor used for controlling on / off action of a traffic light, the microprocessor is provided with a manual input device, a forced switch device, an intelligent detection device and a telecommunication module, and the microprocessor receives a traffic light parameter modifying instruction from the intelligent controller and an instruction from the regional controlled traffic control centre to modify the traffic light control parameters according to a preset control mode or control function. The control system can automatically adjust the traffic light control parameters according to traffic flow variation in different directions and traffic condition of the whole region, thus improving pass efficiency of the crossing and realizing regional traffic optimization.

Description

technical field [0001] The invention relates to an intelligent traffic light control system with global control, 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 th...

Problems solved by technology

[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 cannot always be in the best state

[0003] In addition, this kind of traffic light control system is only based on the traffic conditions of the intersection, and cannot realize the overall traffic optimization in the whole area.
