1、 I 毕业设计 课 题 名 称 基于车流量的智能交通灯控制系统的设计 II 摘要 随着现代社会对交通运输的日趋依赖， 交通灯成为了人们生活中不可或缺的一部 分。传统的交通灯控制系统虽然在一定程度上可以满足指挥路口交通的需要，但随着 城市规模的不断扩大，原有的交通灯控制系统已经表现出明显的缺点：红绿灯时间相 对固定，不能伴随车流量的改变而调整红绿灯的显示时间。本论文以中、小城市区域 交通控制为研究对象，以交通工程基本理论为基础，结合当前的单片机应用技术，对 智能交通灯控制系统进行了分析和研究。 文章论述了基于 AT89C51 单片机的交通灯控 制系统，该系统能根据路口车流量变化而改变交通灯闪亮时

2、间，达到智能控制交通的 目的。该系统具有实用性强、操作简单、扩展性好等特点。 关键词：车流量；交通灯；智能控制 I ABSTRACT With increasing reliance on transportation in modern society,Traffic lights have become an important part in pepoles daily lives. To some extent, traditional traffic control systems can meet the needs of the traffic junction, however

3、, with the continuous expansion of city scale, the traditional traffic lights control systems have showed obvious shortcomings: a relatively fixed display time of traffic lights, which can not change as the different traffic flow at the crossing. In this thesis, according to basic traffic engineerin

4、g theory, combined with current technology and application of microcotroller, which does detai analysis and research on intelligent traffic lights control system. This article discusses traffic lights control systems based on AT89C51 microcontroller, which can display different time of traffic lights in accordance with the actual traffic flow, and achieve the purpose of intelligent control of traffic. Key words:Traffic flow; Traffic lights; Intelligent control 1 目 录 摘要. II ABSTRACT II 目录. 1 第
