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
