With the development of the social and scientific technological level, traffic control system also develops towards the more intelligent, more efficient direction. Based on the careful analysis on the existing traffic control system, this paper designed a project, which has the emergency lights pattern by Micro Controller Unit. This project is easy, simple, and can be used in Actual production and life. Traffic intelligent control system consists of AT89C51, nixie tube countdown display, LED lights direction, emergency traffic disruption button pattern. In addition to prove theoretically, I also use STC89C58 Micro Controller Unit, MAX202 level conversion, serial ports download programming burning software and USB power supplied for making of objects, making the theoretical solution into reality, and further demonstrated the reliability of the system.. This design work mainly divided into the following several aspects: first, design the whole system, drawing principle diagram to realize functions such as countdown display, vehicles going straight and turning, emergency traffic; Second, perfect every function, sure device paramet
