The invention provides a vehicle-road cooperation method based on edge calculation, and the method comprises the steps: obtaining an urban traffic network map, and obtaining road section information through a sensor; calculating a road combination coefficient of each intersection through an edge calculation node according to the road section information; calculating an intersection road combination weight according to each intersection road combination coefficient; a system used in the method comprises a road section information acquisition module, a road combination coefficient calculation module, a road combination weight control module and a control module, the traffic flow change condition can be accurately mastered in real time through the method and the system, the time of the traffic light is controlled according to the road combination coefficient and the road combination weight, and the traffic flow change condition can be accurately controlled according to the road combination coefficient and the road combination weight. The method is more suitable for actual traffic demands, so that the efficiency and safety of traffic operation are improved. The traffic light is connected with the main power supply line and the standby power supply, thereby effectively guaranteeing the power supply stability of the traffic light, reducing the power waste, and improving the energy utilization rate.

    本发明提出了一种基于边缘计算的车路协同方法,所述方法包括:获取城市交通网地图,通过传感器获取路段信息;根据所述路段信息,通过边缘计算节点计算各个路口路合系数;根据各个路口路合系数计算路口路合权重;根据路合权重控制交通灯,此方法用到的系统包括路段信息获取模块、路合系数计算模块、路合权重控制模块和控制模块,通过此方法和系统能够实时准确地掌握交通流量变化情况,并根据路合系数和路合权重来控制交通灯的时间,使其更加适应实际的交通需求,从而提高交通运行的效率和安全;通过将红绿灯连接主供电线路和备用电源,能够有效地保证红绿灯的供电稳定性,减少电力浪费,提高能源利用率。
