| 摘 要： | 基于超声测距原理,以MSP430单片机为控制核心,设计了根据道路实时车流量来动态调节各路口通行时间的智能交通灯控制系统。通过相关算法将超声测距模块的输出回响信号转换成车辆信号,计算出某时刻车道在一段固定距离内的车辆数,并动态分配车道车辆的通行时间,从而提高了交通路口通行效率,有效缓解交通拥堵。系统引入手动遥控模块,可以应对严重交通堵塞。

| Abstract: | Based on the theory of ultrasonic ranging,this article introduced an intelligent traffic light control system that can dynamically adjust the passing time according to the real-time traffic flow.The system uses MSP430 singlechip as its control core.According to the related algorithm,it converts the output signal of the ultrasonic ranging module into vehicle signal,calculates out the traffic flow in a driveway of a fixed distance at that time and dynamically adjusts the passing time.In this way,the efficienc... |
