Description

technical field [0001] The invention relates to the field of optimal control of traffic signals at multiple crossings in a regional road network, in particular to a geomagnetism-based regional self-optimizing signal control method and device. 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. The optimal control of road network traffic signals 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...
