The embodiment of the invention discloses a traffic signal control method and device for multiple intersections and a medium, belongs to the technical field of intelligent traffic, and solves the problem of low real-time performance and accuracy of traffic control for multiple intersections. Obtaining driving data of vehicles passing through a specified intersection in the to-be-detected multi-intersection so as to determine a driving data set based on a time sequence corresponding to the specified intersection; dividing the driving data set into a plurality of groups, and inputting the plurality of groups of driving data sets into different traffic state prediction models to obtain traffic data corresponding to the to-be-detected intersection at the next moment; determining a traffic state change type corresponding to the to-be-detected intersection based on the traffic data at the current moment and the traffic data at the next moment; and determining a target state corresponding to each specified intersection based on the traffic state change type, the traffic change data and the road network diagram of the to-be-detected multi-intersection, generating a traffic signal lamp instruction based on the target state, and controlling the traffic signal of the to-be-detected multi-intersection.

    本申请实施例公开了一种多交叉路口的交通信号控制方法、设备及介质,属于智能交通技术领域,解决多交叉路口的交通控制实时性与准确性较低的问题。获取待测多交叉路口中经过指定路口的车辆行驶数据,以确定出指定路口对应的基于时序的行驶数据集;将行驶数据集划分为多组,并将多组行驶数据集输入不同的交通状态预测模型,以得到待测交叉路口对应的下一时刻交通数据;基于当前时刻交通数据与下一时刻交通数据,确定待测交叉路口对应的交通状态变化类型;基于交通状态变化类型、交通变化数据以及待测多交叉路口的道路网络图,确定出各指定路口分别对应的目标状态,基于目标状态生成交通信号灯指令,对待测多交叉路口的交通信号进行控制。
