Application of Intelligent Traffic Control Based on PLC

Abstract

we know, the transport system is a complex system of ambiguity, randomness and uncertainty . It is very difficult to establishthe mathematical model and sometimes it is impossible to use the existing mathematical methods to describe it. At the current inside the country the traffic lights at crossroads is generally controlled by the timing switch. At present domestic urban transport is commonly used in the timer traffic lights to control the passage of vehicles, with the occurrence of uncertainties and the ground conditions often changing. According to the difference of the vehicles stagnation flow and the traffic lights time lengths of holdup at any each intersection, to use the Siemens S7-200 programmable control system automatically adjusts traffic lights and vehicles circulation. The application of the system will greatly alleviate the traffic congestion, improve the efficiency of road, and make a contribution to energy conservation and emission reduction. In the future we will be living in the era with the smooth traffic flow, the good environment and social sustainable development. Keywords-stagnation flow; PLC; Intelligent control
