Modern traffic management systems requires the integration of such facilities as traffic signal control system, information release system, video frequency monitoring system as well as communication network and traffic management center to realize ordered, safe, quick, comfortable and sustainable development. Realization of real-time traffic management and environment control require more facilities such as PLC, traffic controller, LED display screen, IP telephone and video frequency camera. Most of modern intelligent traffic systems use the TCP/IP network communication as the main approach for equipment communication, of which, the advantage lies in the low installation cost and high degree of system integration. The redundant ring Ethernet topological structure aims to ensure the uninterrupted operation of the system.
