Design and Realization of Multi-Stage Traffic Signal Controller of Variable Phase

Abstract:

The present traffic controllers are most run in 2,3 or 4 phase mode at single point intersections, but the transition of different phase modes during traffic controlling is not flexible. In view of this deficiency, a multi-stage traffic signal controller of variable phases was designed and realized. It is equipped with a single chip microcomputer as the core, signal lights driver circuit, real-time clock, keys and LCD display modules etc. By means of physical simulation, the results show that this controller can run reliably according to system parameters and achieve automatic transition of 2, 3 or 4 phase mode in different stages, thus it also is proved that this controller is more flexible and efficient to control traffic flow.
