The invention relates to an intersection vehicle queue and signal cooperative control optimization method in a mixed traffic environment, and belongs to the field of road intersection signal control. According to the method, a typical two-way six-lane intersection is considered, the mixed traffic flow comprises a CAV and an HDV, a road section with a certain length of the intersection is set as a vehicle formation area and a vehicle speed regulation and control area, and a control center, an RSU, a vehicle detector and a signal lamp are configured; the RSU can obtain the driving state of the CAV and synchronize vehicle information to the control center; in the vehicle formation area, the CAV guides rear vehicles to form a compact and fast-moving vehicle fleet; and in the vehicle regulation and control area, the control center reserves a passage gap and signal timing for the arriving vehicle to pass through the intersection, and plans a driving track for the CAV to enable the CAV or a guided motorcade to pass through the intersection in the reserved passage gap. According to the invention, the vehicle track and the traffic light passing phase can be optimized at the same time, so that the overall operation efficiency of a traffic system is obviously improved.

    本发明涉及一种混行交通环境下交叉口车辆队列与信号协同控制优化方法,属于道路交叉口信号控制领域。该方法考虑一个典型的双向六车道交叉口,混合交通流包括CAV和HDV,该方法将交叉口一定长度的路段设置为车辆编队区和车速调控区,配置控制中心、RSU、车辆检测器和信号灯;RSU可获取CAV的行驶状态并将把车辆信息同步给控制中心;在车辆编队区,CAV引导后方车辆编入紧凑而快速行进的车队;在车调控区,控制中心为到达车辆预留可通过交叉口的通行间隙和信号配时,并为CAV规划行车轨迹使其或引导的车队能在预留的通行间隙通过交叉口。本发明能同时优化车辆轨迹和信号灯通行相位,从而使交通系统的整体运行效率得到明显提升。
