Research on Real-time Control of Induced Signal at Intersection Based on Internet of Things Technology

为实时、合理控制交叉口感应信号,提出了基于物联网技术的交叉口感应信号实时控制方法。采用RFID技术采集干线交叉口到达流量、支线交叉口到达流量,根据流量转移的交叉口感应信号控制方法预测交叉口未来流量转移值,获取交叉口感应信号需要控制的周期数,解决交叉口拥堵问题,完成交叉口感应信号控制。实验结果表明,设计方法的交叉口车辆排队长度和排队时间得到了大幅度缩短,提升了车辆拥堵情况解除实时性,可实现对交叉口感应信号的实时、合理控制。

In order to control the intersection inductive signal in real time and reasonably,a real-time control method of intersection inductive signal based on internet of things technology is proposed.RFID technology is used to collect the arrival flow of main line intersections and branch line intersections.The future flow transfer value of intersections is predicted according to the intersection sensing signal control method of traffic transfer,so as to obtain the cycle number of intersection induction signal to control,solve the intersection congestion problems,and complete the intersection induction signal control.The experimental results show that the queue length and queuing time of vehicles at the intersections are greatly reduced,the real-time performance of vehicle congestion is improved,and the real-time and reasonable control of intersection induced signals can be realized.
