Abstract
The present application discloses a video-based main road cooperative signal machine control method, which includes: installation of video detectors at each intersection of the main road; data acquisition and communication of a single intersection; data acquisition and storage of multiple intersections; data processing of the main road coordination signal control; signal command release service and signal light control. The application adopts active video detection technology, which can accurately detect the traffic state of multiple intersections of the main road, formulate an optimized signal control scheme, provide optimal decision and emergency plan for the control of traffic light of the main road, improve the traffic efficiency of intersections and effectively alleviate traffic congestion on trunk roads.
