摘要

文中提出了面向HDV/CAV混行交叉口的车道组织与信号控制协同优化模型,支持交叉口CAV专用车道及相位协同优化.以典型城市道路交叉口为例,分析了不同CAV渗透率下交叉口车道配置及信号控制策略的变化规律.结果表明:当CAV渗透率超过60％时,设置CAV专用车道及相位将显著降低交叉口车均延误.且CAV渗透率在70％～90％时,车均延误降幅超过30％;当CAV渗透率在60％～80％时,HDV车辆的延误降幅更为明显.

Abstract

A cooperative optimization model of lane organization and signal control for HDV/CAV mixed intersections was proposed to support the cooperative optimization of CAV lanes and phases at intersections.Taking a typical urban road intersection as an example,the changing law of intersection lane configuration and signal control strategy under different CAV permeability was analyzed.The re-sults show that when the CAV permeability exceeds 60％,setting CAV lanes and phases will signifi-cantly reduce the average vehicle delay at intersections.And when the CAV permeability is 70％～90％,the average vehicle delay decreases by more than 30％.When the CAV permeability is 60％～80％,the delay of HDV vehicles will decrease more obviously.
