' k( e' P/ U+ dWith the construction of socialism, the city scale in expanding constantly,urban traffic is also in constant improvement and improvement, traffic flow restriction of socialist construction has become one of the important factors. The system USES the monolithic integrated circuit ATAT89S52 to design and realize the traffic light controller can according to actual traffic through the mouth AT89S52 chip set red, green P1 burning time function; Traffic lights circulation lighted, with 5 seconds countdown yellow lights flashing warning. This system is practical, simple operation and function expansion is strong.4 m# M. H) ]3 |+ k1 T/ U
