Intelligent traffic light control system based on real time traffic flows

Currently, traffic congestions are the most serious issues that most cites are facing. In order to improving the urban traffic orders, as well as to alleviating traffic pressures, this paper presents an urban traffic control system, which is designed based on the real time traffic flow information. The proposed design has combined with traffic control theory, application of single chip computer and ultrasonic technology, design and research of the traffic control system based on traffic. Article control core of the system is the MCS - 51 single chip microcomputer, which achieves real-time monitoring by using ultrasonic sensors for road vehicle. Compared with the traditional control system, the system has the following characteristics: the duration time of traffic signal can be smartly set according to the number of road vehicles; a priority of lane can be assigned according to the actual demand when a vehicle is rarely at night, etc. Therefore, the traffic signal's duration time can be smartly and intelligently adjusted according to the real time road traffic flow information.
