The invention belongs to the technical field of intelligent traffic, and particularly relates to a multi-intersection bus priority passage control system and method based on 5G-V2X, and the system comprises an RSU, an OBU and a cloud server. According to the invention, 5G-V2X equipment is used for collecting the driving state (speed, position and the like) of a bus, the distance between the bus and a current intersection, the position of each intersection and the phase of a traffic light in real time; using a genetic algorithm to globally optimize the traffic light phase duration and the bus speed of a plurality of intersections by taking the minimum green time ratio as a judgment basis; the optimized bus driving suggested speed and the optimized front multi-intersection guidance phase are sent to the bus and the intersection signal machine through 5G, multi-intersection priority passing is achieved, and the passing efficiency of the bus at multiple intersections and the punctuality rate of the bus are improved.
本发明属于智能交通技术领域,具体涉及一种基于5G‑V2X的多路口公交优先通行控制系统及方法,该系统包括RSU、OBU以及云服务器。本发明使用5G‑V2X设备实时采集公交车辆的行驶状态(速度、位置等)、公交车与当前路口的距离以及各路口位置和红绿灯的相位;以绿信比最小为判断依据,使用遗传算法对多个路口红绿灯相位时长和公交车车速进行全局优化;优化后的公交车行车建议速度和前方多路口指导相位通过5G发送至公交车和路口信号机,实现多路口优先通行,提高公交车在多个路口的通行效率和公交车的准点率。
