Intelligent signal lamp control method based on urban major and collector road intersections

The invention relates to an intelligent signal lamp control method based on urban major and collector road intersections. Major road entrance lanes of the intersections can allow turning left, going straight and turning right and are provided with earth induction coils A1, sensors B01, sensors B03 and sensors C, major road exit lanes of the intersections are provided with earth induction coils A2,data acquired by the earth induction coils A1, the earth induction coils A2, the sensors B01, the sensors B03 and the sensors C are processed and analyzed a microprocessor M, and prolonged time of green lamps of major roads of the intersections is determined according to a delay method of the green lamps. According to the method, timing is achieved by sufficiently utilizing signals, vehicles of the intersections are evacuated, time is saved, and jam is decreased. 本发明涉及种基于城市主次干路交叉口的智能信号灯控制方法，交叉口的主干路进口道可进行左转、直行和右转，交叉口的主干路进口道安装地磁感应线圈A、传感器B、传感器B和传感器C，交叉口的主干路出口道安装地磁感应线圈A；微处理器M对地磁感应线圈A、A，传感器B、传感器B和传感器C所采集的数据进行处理和分析，根据绿灯延时方
