Design of Intelligent Traffic Light Controller
Abstract: In view of the present city traffic light management system shortcomings is not flexible, this design proposes using AT89S51 as the core MCU to design the traffic light controller, alternating with hardware circuit simulation of traffic signal, implementation cycle traffic lights lit, with LED digital tube as the countdown indicator. At the same time, the system increases the vehicle flow detection circuit, using the fuzzy control algorithm to adjust the traffic lights time, purpose is to guarantee the traffic safety at the same time the maximum improve the traffic rate, can reduce traffic accidents, save the consumption of resources, has the important practical significance.
