The Design of Real-Time Traffic Flow Control System Based By PLC
Abstract:The object of study of the real-time traffic flow control system is a typical traffic intersection, the purpose is to improve the security situation for people to travel and goods to transport, and improve traffic utilization. Traffic intersection is a randomness and uncertainty system, through the establishment of a traffic model for the analysis of the state, the use of the inductive sensor detects vehicles through signal detection area and enter the programmable logic controllers, treated after the output terminal of the programmable logic controller controls the traffic lights at the time. Simulation results show that the design can meet the real-time control of traffic lights according to the number of real-time traffic flow. Control system is flexible, and it has a certain practical value.
