The method uses radar detection data acquisition technology, can accurately detect the traffic state of the intersections of a trunk road, develops an optimal signal control scheme, provides an optimal decision and emergency plan for the traffic signal light control of the trunk road, improves the traffic efficiency at the intersections, and effectively alleviates congestion at the intersections.

Description

technical field [0001] The invention relates to the technical field of coordinated optimization control of traffic signals at multiple intersections on a trunk road, in particular to a method for controlling a cooperative signal machine on a trunk road based on a radar detector. Background technique [0002] Urban traffic congestion and accidents are becoming more and more frequent, especially the serious congestion incidents on the main roads of urban traffic. If the traffic flow cannot be effectively regulated in real time, it will cause the spread of road congestion, reduce the efficiency of road operation, and cause great time and economic losses to the public. [0003] An advanced and applicable traffic management system is one of the most effective ways to solve urban traffic congestion, and traffic signal control is the core of the traffic management system. The optimal control of traffic signals on main roads can maximize the advantages of regional traffic guidance an...

Problems solved by technology

[0005] At present, the signal control methods mainly include timing control, multi-period control, induction control and adaptive control, etc. The traditional model algorithm is too rigid to set the threshold according to the change of a certain traffic parameter to optimize the signal, which will cause the system to change the state. Misjudgment; the present invention proposes a radar detector-based trunk road cooperative signal machine control system, based on the feedback control theory, through the real-time detection and comprehensive analysis of the average traffic density at each crossing of the trunk road, the intersection signal control optimization algorithm is extracted , can greatly improve the traffic operation efficiency of arterial roads
