一种车流量自适应交通灯控制系统的实现

The implementation of an adaptive vehicle flow traffic light control system

介绍了一种基于555定时器和74L S161计数器的流量自适应交通灯控制系统,该系统采用车流量检测电路实现交通灯亮灭持续时间的自适应控制,较好地解决了当前多数交通灯控制系统存在的不能根据道路上车流量的情况自适应调节的缺点。该系统经组装、调试,并在路口试验,效果良好。

This paper introduces a flow auto-adapted traffic light control system, which is based on the 555 timer and the counter 74LS161 logical device. The system mentioned above uses traffic flow detection electronic circuit to control the traffic lights adaptively. It solves the problem effectivety that many current traffic lights control systems are not able to adjust themselves according to the road traffic situation. And the results are good when the system, assembled and debugged, is tested in a street intersection.
