Research on Bus Priority Control Strategy Based on RFID in Vehicle Electronic Tags

摘要:

针对现有的信号控制系统不能对达到交通流做出精准预测,只能被动适应交通流达到而无法主动引导交通流；提出基于RFID车载电子标签车路通信环境,引导公交车辆适时到达并通过交叉口；以交叉口总延误最小化为目标,综合考虑当前交通流运行状态,建立公交信号优先控制模型,最大限度降低交叉口的车均延误,减少平均停车次数,使绿灯的利用率最大化；仿真实验表明,控制模型的控制效益明显提高,实现公交优先目标。

Abstract:

In view of the existing signal control system can't achieve traffic flow to make accurate forecasts, the current state is:passively adapt to traffic flow, not actively guide the traffic flow. RFID-based vehicle electronic tag build car-communication environment, and guide timely arrival of buses through the intersection. In the intersection objective of minimizing the total delay, considering the current state of traffic flow, establish bus signal priority control model, to minimize the intersection average delay, reduce the average number of stops, in order to maximize the utilization of green. Simulation results show that the control model of control efficiency has improved significantly, to achieve public priorities.
