基于单片机的智能交通灯控制系统的研究与设计

摘要

针对道路交通拥挤、交叉路口经常出现拥堵的情况,本系统采用单片机作为核心控制器,组成一个集车流量采集、处理、自动控制为一身的闭环控制系统。通过仿真本设计能模拟基本的交通控制系统还能进行倒计时显示,车流量检测及调整,交通违规处理和紧急处理等功能。%In view of heavy traffic flow on the roads and increased congestions at intersections,this system adopts MCU as its core controller,this system is a closed-loop control system integrating traffic flow acquisition,processing and automatic control functions.This design can simulate the basic traffic control system.It uses red,green and yellow lights to respectively represent stop,pass and wait signals,and also provides such functions as countdown time display,traffic flow detection,traffic violation disposal and emergency treatment.
