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 geomagnetism. 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 the traffic efficiency of the trunk line.

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 self-optimizing signal control method and device for trunk lines based on geomagnetism. 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] Geomagnetic vehicle detection technology is a technology that detects the number, speed, and occupancy of passing vehicles by installing geomagnetic acquisition equipment on roads that are complex or prone to congestion, and transmits the collected data back to the s...
