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 single-point self-optimization signal control method based on array radar, through the real-time detection and comprehensive analysis of the intersection operation index, and the extraction of the intersection signal control self-optimization algorithm, which can greatly improve the traffic at the intersection operation efficiency

Description
technical field [0001] The invention relates to the field of optimal control of traffic signals at a single crossing, in particular to a single-point self-optimizing signal control method and device based on an array radar. Background technique [0002] Urban traffic congestion and accidents are becoming more and more frequent, especially at intersections. If the traffic flow cannot be effectively managed in real time, it will cause road congestion to spread, reduce the operation efficiency of intersections, and cause great time and economic losses to the public. [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 server center through wired or wireless networks for further processing. The processing technology can carry out dynamic traffic signal control throug...
