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.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 results show that when the CAV permeability exceeds 60%,setting CAV lanes and phases will significantly 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.
