The invention provides a regional signal control strategy optimization method, device and system, and the method comprises the steps: obtaining a lane-level store-and-forward model which is used for describing the process that the number of vehicles on each lane in a region continuously changes along with the entry of upstream vehicles and the exit of downstream vehicles, the area comprises at least one intersection; on the basis of the store-and-forward model, obtaining expected passing time lengths of all lanes in the area; based on the expected passing duration of all lanes in the area, the phase duration of each phase in the area is determined, and the phase duration is used for representing the green light duration of the phase; and generating an optimized signal control scheme based on the phase duration of each phase in the region, the optimized signal control scheme being used for controlling traffic signal lamps in the region. The optimized signal control scheme obtained by the technical scheme can optimize the traffic condition in the area and reduce the congestion of the intersection in the area.

    本申请提供一种区域信号控制策略的优化方法、装置和系统,该方法包括:获取车道级的存储转发模型,所述存储转发模型用于描述区域内各个车道上的车辆数随着上游车辆的驶入和下游车辆的驶出持续变化的过程,所述区域内包括至少一个交叉口;基于所述存储转发模型,获取所述区域内所有车道的期望通行时长;基于所述区域内所有车道的期望通行时长,确定所述区域内各相位的相位时长,所述相位时长用于表征所述相位的绿灯时长;基于所述区域内各相位的相位时长,生成优化后的信控方案,所述优化后的信控方案用于对所述区域内交通信号灯进行控制。该技术方案得到的优化后的信控方案可以对区域内的交通状况进行优化,减少区域内交叉口的拥堵。
