摘要:

为提高立交桥通行效率,在考虑车辆通过立交桥过程中存在多次分离、交汇行为基础上,利用时延Petri网(timed Petri net, TdPN)建立智能网联车完整通过过程仿真模型;提出基于车辆优先级的速度引导策略,并建立智能网联车协作控制模型,从而组成完整的互通立交TdPN模型。通过仿真予以校验,并与立交桥出口及其衔接区协同控制方法、立交区域内多合流区协同控制方法作对比,结果表明:当交通需求较大时,本文方法控制效果最佳,能进一步提高通行效率,缓解交通压力。

Abstract:

To improve the traffic efficiency of interchange, a simulation model of complete process is built by timed Petri net (TdPN) considering multiple separation and merging behaviors in the process of connected and automated vehicles (CAVs) passing through the interchange. In the light of vehicle priority, a speed guidance strategy is proposed and a CAVs cooperative control model is established, so as to form a complete interchange TdPN model. This method is verified by simulation and compared with the cooperative control method of interchange exit and its connecting area, cooperative control method of multi-merging areas within the interchange. The results indicate that when the traffic demand is large, the control effect of this method is the best, which can further improve traffic efficiency and relieve the traffic pressure.
