It caused the waste of road resources and it wasted peoples time. The phenomenon of road congestion is m ore and more badly and the economic loss is serious. Now, the present traffic system has been unable to meet the needs of economic development. According to the phenomenon of the road traffic congestion and the traffic jam in the intersection, this paper put forward the design scheme of the intelligent traffic light control system based on SCM in behind of the depth analysis for the current traffic control . SCM can not only controls the time of the traffic light through the timer, but also receives the control signal and sets time. The traffic light control system use MCS-51 single chip microcomputer as control chip, in addition to the basic function of traffic lights, has prompted the countdown, traffic detection and adjustment, serial communication and infrared receiver functions. It can improve the traffic lights intelligent, reliability and practicability. Theory proves that this system can simple, economic, efficient grooming of traffic, and traffic speed to maximize the improvement of road vehicles.
