Abstract: When the vehicle passes through the intersection, it will be delayed due to traffic signal control. A speed guidance strategy at signalized intersections in a cooperative vehicle-infrastructure environment was proposed. Considering the guided vehicle and the ordinary vehicles behind it as a fleet, the purpose of the vehicle passing through the intersection without stops under the guidance of speed guiding strategy could be achieved by analyzing the speed and position of the vehicle and judging whether the vehicle under different driving states can pass. The proposed speed guidance strategy was analyzed and evaluated in the established simulation environment based on the microscopic traffic simulator VISSIM and MOVES emission model. The simulation results show that the proposed speed guidance strategy can significantly reduce delay and queue length, improve vehicle travel efficiency, and reduce vehicle pollution emissions.

摘要： 车辆在通过城市道路交叉口时会因为信号灯控制造成一定延误。通过提出一种车-路协同环境下的信号交叉口速度引导策略，将被引导车辆及其后的普通车辆视为一个车队，并对车辆的速度和位置进行分析，对车辆不同行驶状态能否通过交叉口进行判断，以达到车辆在速度引导下能够不停车通过交叉口的目的。基于微观交通仿真软件VISSIM和MOVES排放模型，在构建的仿真环境中对该速度引导策略进行分析和评估。仿真结果表明：所提出的速度引导策略能显著减少延误和车辆排队长度，提高车辆行驶效率，并显著降低车辆污染及排放。
