近年来，随着科技的飞速发展，电子器件也随之广泛应用，其中单片机也不断深入人民的生活中。
本模拟交通灯系统利用单片机AT89C51作为核心元件，实现了通过信号灯对路面状况的只能控制，从一定程度上解决交通路口堵塞、车辆停车等待时间不合理、急车强通等问题。
系统具有结构简单、可靠性强、成本低、实时性好、安装维护方便等有点，有广泛的应用前景。
本模拟系统由单片机/软件系统，两位8段数码管和LED灯显示系统等组成，较好的模拟了交通路面的控制。

The simulation traffic light system using single chip microcomputerAT89C51 as the core element, achieved through the lights on the road can only control, from a certain extent, solve the traffic intersection congestion, vehicle parking waiting time is not reasonable, nasty car problems. System has a simple structure, high reliability, low cost and good real-time performance, installation, maintenance is convenient wait for a bit, have broad application prospects.This simulation system by single chip computer/software system, two section 8 of digital tube and the LED display system and so on, better simulated the road traffic control.Key Words:The traffic lightSingle chip microcomputerDigital tubeLED lights目录第一章前言........................................ 错误！未定义书签。
