Geomagnetic detection-based self-organizing intelligent signal control method

The invention relates to a geomagnetic detection-based self-organizing intelligent signal control method. The method comprises the following steps that: (1) a vehicle detector detects the traffic flow of each driveway entrance of an intersection and uploads traffic flow data to a signal controller or a background in real time; and (2) the signal controller or the background calculates the average saturation X of each signal phase driveway of the intersection, and controls traffic lights according to the average saturation X. In the method, the vehicle detector detects the traffic flow and uploads the traffic flow information data to the signal controller, and the signal controller calculates the average saturation X of each signal phase driveway of the intersection and controls the traffic lights by adopting a corresponding control mode according to different average saturation X. The method fully utilizes the time of green light, and can effectively eliminates a green light emptiness phenomenon of the intersection and improve traffic efficiency.
