A Design of the Traffic Lights Intelligent Control System Based on ARM and Zig Bee

With the rapid development of economy, Road traffic environment is changing slowly, the efficiency of the people and car traffic is becoming more and more aroused people's attention, As one of important infrastructure of road network, traffic lights have a great impact on traffic efficiency. In the traditional traffic lights control system, the control of people and Car traffic was through relatively reasonable fixed lights switch time, after the traffic statistics, analysis of the history of road intersections. This can lead to reduce the traffic efficiency, such as, there is a large flow in the red light direction but a small flow in the green light direction at the same time, Besides, The traditional control system adopts embedded wire method on the system arrangement mostly, This means the high cost in maintenance and maintenance. On the basis of retain fixed switching time, This design scheme based on ARM, Zig-bee wireless network technology and magnetic sensors to improve the traffic efficiency through the real-time collection, analysis on the road traffic, according to the results of real-time adjust the traffic lights control strategy.
