Abstract

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.

Description

technical field [0001] The invention relates to the technology of intelligent signal lamps, in particular to an intelligent signal lamp control method based on the intersection of urban main and secondary arterial roads. Background technique [0002] Nowadays, with the development of social and economic level, the number of private cars is increasing year by year, the level of urbanization is getting higher and higher, and the traffic congestion of urban roads is becoming more and more severe. In urban road intersections, there are often situations where the timing of signal lights cannot adapt to the actual traffic demand. There are delays in queuing of vehicles on the main road, serious congestion, and no vehicles passing through the green light time of the secondary road. The green light time cannot be fully utilized, resulting in signal distribution. Time is wasted, and congestion cannot be evacuated. According to the method of system control, the types of traffic signa...
