In order to meet the requirement of regional coordination intelligent transportation system , this paper proposes a kind of traffic lights control terminal based on the application of single-chip microcomputer. This traffic light control terminal can exchange information with the intelligent coordinating central control system, feeds back information of traffic flow, adjust the working of the traffic lights according to the requirement of the central control system. The terminal adopts the mode of double MCU signal validation and applies the watch-dog technology, which can correct possible errors that may occur during run time. Moreover, with an additional alerting unit and automatic switchover standby module , the terminal can raise alarm in response to errors and automatic switchover to the stand-by controller when goes into failure. The traffic lights control terminal can greatly guaranteed safety and stable running of the traffic system.
