With the road traffic congestion problems become more and more serious, and the current traffic lights don’t possess the function of revising timely and flexible, it can't meet the requirements of real-time controlling and make the traffic in intersection more efficient. The design of Microcontroller-based traffic signal controller fixes this problem. It based on STC90C51 as CPU solutions; LED lights and digital pipe were used as display module; 8 independent keyboards were used as the only manual input device; Software used the C programming language. The intelligent traffic light system covered the multi-phase and multi-period. So we could choose two-phase/four-phase/six-phase according to the particular road and traffic condition. Besides, it took the special status of emergency vehicles into account. It also had a manual input keyboard so that you could adjust the signal at any time. This design can effectively improve the traffic congestion problem.
