The invention belongs to the technical field of vehicle infrastructure cooperation, and particularly relates to a bus signal priority control method and system. Firstly, a bus is controlled to run on a road with a formulated trunk green wave scheme, and the trunk green wave scheme is formulated based on a static trunk timing coordination control strategy; then, when the bus drives to approach a certain intersection, whether the bus can pass the intersection preferentially is predicted according to the real-time position information of the bus and the real-time traffic light information of the intersection; and under the condition that the prediction result is that the bus cannot pass through the intersection preferentially, obtaining a bus control scheme and/or a traffic signal controller control scheme of the intersection by adopting a real-time priority control strategy so as to control the corresponding bus and/or the traffic signal controller, so that the bus can pass through the intersection preferentially. According to the method, dynamic and static are combined, advantages are complementary, the problem that a static or dynamic signal priority scheme is independently applied is effectively solved, the green light passing rate of the bus is integrally improved, and technical support is provided for achieving the minimum bus operation delay.

    本发明属于车路协同技术领域,具体涉及一种公交信号优先控制方法及系统。首先,控制公交车在制定的干线绿波方案的道路上行驶,干线绿波方案是基于静态干线定时协调控制策略制定得到的;然后,在公交车行驶至靠近某一路口时,根据公交车实时位置信息和该路口的实时红绿灯信息,预测公交车能否优先通过该路口;在预测结果为不能优先通过的情况下,采用实时优先控制策略得到公交车控制方案和/或路口的交通信号机控制方案,以控制相应公交车和/或交通信号机,使公交车能够优先通过该路口。本发明的方法动静结合,优势互补,有效解决单独应用静态或动态信号优先方案的问题,整体提高公交车绿灯通过率,为实现公交运营延误最小提供技术支撑。
