基于电子车牌的交叉口感应信号控制方法研究

The Research of Intersection Sensor Signal Control Method based on Electronic License

提出了一种基于电子车牌的交叉口感应信号控制方法,该方法通过设置在交叉口处的阅读器与装有有源电子标签车辆互动,得到路段区间上的车辆信息。以车辆密度作为感应控制绿灯是否延长的评价标准,车辆密度高于阈值则绿灯延续,反之,切换相位。通过仿真对比分析表明,改进后的感应控制策略能够在高饱和度路口实现实时有效交通信号控制,克服了以车辆间隔时间作为绿灯延长标准的感应控制在高饱和度下失效的弊端,提高了城市交叉口绿灯利用率。

Propose a sensing signal intersection control method with electronic license based on the design by setting the intersection readers to interact with active electronic tags equipped vehicles,vehicle information is obtained on the road section.The vehicle detection sensor may control based on the green density as evaluation criteria,and it is extended when the vehicle is higher than the threshold,otherwise the control phases will be switched.Analysis shows the improved control strategy can achieve real-time traffic signal control effectively in higher saturation intersection,whice overcome the traditional sensor control failure at high saturation drawbacks and improve the utilization of urban intersection comparative analysis by simulation.
