摘　　要：随着社会经济的快速发展以及人们生活水平的提高,机动车数量也在急剧增加,交通问题逐渐成为人们关注的重点对象。本设计主要是针对主副干道十字路口交通灯进行了智能化设计,可根据车流量的大小改变指示通行的时长。采用AT89C51单片机作为中心控制器,可控制红灯、绿灯、黄灯按时间交替变换,并附加了倒计时读秒功能。在此基础上,通过传感器对车流量进行实时数据采集,通过A/D转换器将采集的数据传送给控制中心,进行分析比较。根据比较的结果,控制指示灯的时长,从而达到交通信号灯可根据车流量智能调节的目的,提高了交叉口的通行效率。With the rapid development of social economy and the improvement of people＇s living standard, the number of motor vehicles is increasing rapidly. The traffic problem has gradually become the focus of attention. This design mainly aims at the main and the main road intersection traffic light to carry on the intellectualized design, may according to the traffic flow size changes, indicated the passage time length. Using AT89C51 microcontrolter as the central controller, which can control the red, green and yellow lights to transform time alternately, and added the countdown function. On this basis, real-time data acquisition of traffic flow is carried out through sensors, and the collected data is transmitted to the control center through the A/D converter for comparison and analysis. According to the result of comparison, the length of the control indicator lamp is controlled, so that the traffic signal lamp can improve the traffic efficiency of the intersection according to the intelligent regulation of the traffic flow.
