Description

technical field [0001] The invention relates to the field of optimal control of traffic signals at multiple intersections on trunk lines, in particular to a method and device for controlling self-optimizing signals of trunk lines based on array radar. Background technique [0002] Urban traffic jams and accidents are becoming more and more frequent, especially at intersections. The advanced and applicable traffic management system is one of the most effective ways to solve urban traffic congestion. Traffic signal control is the core of the traffic management system. Traffic signal optimization control can maximize the advantages of regional traffic guidance and improve the efficiency of road traffic operation. [0003] Array radar vehicle detection technology is to install array radar acquisition equipment on roads with complex conditions or easy to form congestion to detect the number, speed, and queue length of passing vehicles, and transmit the collected data back to the ...

Problems solved by technology

[0004] 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 self-optimizing signal control method for trunk lines based on array radar. Through the real-time detection and comprehensive analysis of the intersection operation index, the signal control self-optimization algorithm of multiple intersections on the trunk line can be extracted, which can greatly improve road traffic. operation efficiency
