Description: 近年来随着科技的飞速发展，单片机的应用正在不断深入，同时带动传统控制检测技术日益更新。在实时检测和自动控制的单片机应用系统中，单片机往往作为一个核心部件来使用，仅单片机方面知识是不够的，还应根据具体硬件结构软硬件结合，加以完善。
十字路口车辆穿梭，行人熙攘，车行车道，人行人道，有条不紊。那么靠什么来实现这井然秩序呢？靠的就是交通信号灯的自动指挥系统。交通信号灯控制方式很多。本系统采用MSC-51系列单片机ATSC51和可编程并行I/O接口芯片8255A为中心器件来设计交通灯控制器，实现了能根据实际车流量通过8051芯片的P1口设置红、绿灯燃亮时间的功能；红绿灯循环点亮，倒计时剩5秒时黄灯闪烁警示（交通灯信号通过PA口输出，显示时间直接通过8255的PC口输出至双位数码管）；车辆闯红灯报警；绿灯时间可检测车流量并可通过双位数码管显示。本系统实用性强、操作简单、扩展功能强。 -Software Development
