摘　　要：针对交叉口车辆启停问题,提出一种面向出行路径的车辆绿波速度控制方法。该方法以路网交通状态为基础,从出行路径角度出发,通过求取全局最优速度为车辆提供行驶速度建议并对其动态更新,实现车辆不停车经过路径上的所有交叉口到达目的地。仿真结果表明,绿波速度控制方法能大幅减少交叉口的停车次数,车辆通行效率提高超过30%,同时车辆的燃油消耗、CO 2、VOC和NO x的排放量减少约50%,对于提升交通运行效率、减少能源消耗,降低污染排放具有重要意义。To tackle the problem of start-stop at intersections,this paper proposes a green wave speed control model from the perspective of path.The model considers the traffic conditions of road network and dynamically calculates the globally optimal speed for vehicles,enabling them to smoothly pass through all intersections along their paths without stopping.Simulation results confirm that the model effectively reduces the number of stops at intersections,resulting in a remarkable improvement of over 30%in travel efficiency.Besides,the model reduces energy consumption and emissions,with fuel consumption,CO 2,VOC,and NOx emissions decreasing by nearly 50%.The findings validate the promising potential of the proposed model to enhance transportation efficiency and mitigate both energy consumption and pollution emissions.
