The invention discloses a green wave coordination control method and device, equipment and a medium. The method comprises the following steps: in response to a green wave coordination indication, determining a plurality of coordination paths contained in a target path and coordination priorities of the plurality of coordination paths according to steering flow of each intersection in a target area; multiple rounds of iteration are carried out on the multiple coordination paths, in each round of iteration, the maximum number of coordination vehicles serves as a constraint, the coordination paths are split based on the priorities of the coordination paths and the steering flow, split to-be-processed paths and corresponding path priorities are obtained, and on the basis of the path priorities and the reference phase differences of all intersections, the coordination paths are obtained. And determining a candidate phase difference of each intersection. And then, taking the candidate phase difference output by the previous round of iteration as the reference phase difference participating in the operation of the next round of iteration again until the iteration is performed for a preset number of times, so as to improve the overall green wave coordination effect of the road network region.
本申请公开了一种绿波协调控制方法、装置、设备及介质。该方法中,响应于绿波协调指示,根据目标区域内各个路口的转向流量,确定目标路径包含的多条协调路径,以及多条协调路径的协调优先级。对多条协调路径进行多轮迭代,每轮迭代中以协调车辆数量最大为约束,基于协调路径的优先级和转向流量对协调路径进行拆分,得到拆分后的待处理路径以及对应的路径优先级,并基于路径优先级和各个路口的参考相位差,确定各个路口的候选相位差。然后,以前一轮迭代输出的候选相位差作为下一轮参与运算的参考相位差重新迭代,直至迭代预设次数,以提高路网区域的整体绿波协调效果。
