The intelligent control of traffic lights can be realized by combining the ground sensing coil vehicle detection system with the high - performance small Programmable Logic Controller (PLC) .The sensing coil sensor is used to detect vehicle flow ,and the sine wave generated by the oscillation is converted into a pulse signal through the amplification .Using the reversible counter of PLC to add and subtract the pulse signal ,we can obtain the opti-mal working time of the next traffic light cycle through certain intelligent control principle ,and then ,the traffic congestion can be eased .
