Design of Traffic Signal Controller Based on Network

In the paper, a traffic signal controller based on network was designed after analyzing the development and actuality of traffic signal controllers. The controller consisted of Server, Network Bus and IP Nodes. Power line carrier communication module was designed as the medium of network communication, which could meet the requirements of traffic control network for network bandwidth and communication distance. The software based on Firework computing paradigm can achieve efficient data processing and improve the coordination and optimization ability of traffic control system. With precise actual control effect, the controller can reduce equipment cost, lower difficulties of upgrading and maintenance, and provide complete data support for collaborative optimization of traffic network.
