The invention provides a map data processing method and device, equipment, a storage medium and a program product, and the method comprises the steps: obtaining a sample data set of a target intersection, the sample data set comprising driving tracks of vehicles corresponding to traffic lights in at least two directions of the target intersection; according to the sample data set, acquiring a lamp changing moment of a traffic signal lamp corresponding to the driving direction of the vehicle; according to the lamp changing time of the traffic signal lamp corresponding to the driving direction of the vehicle and the lamp changing period of the traffic signal lamp in the target time period, the lamp changing deviation time of the vehicle corresponding to the traffic signal lamp is obtained; and obtaining the phase difference between the traffic lights of the target intersection in the target time period according to the lamp changing deviation moment of the vehicle corresponding to the traffic lights. According to the method provided by the invention, the acquisition difficulty of the phase difference can be reduced, the phase difference acquisition efficiency is improved, and the availability of the map data processing method is improved.

    本申请提供一种地图数据处理方法、装置、设备、存储介质及程序产品,包括:获取目标路口的样本数据集,样本数据集包括:目标路口的至少两个方向的交通信号灯对应的车辆的行驶轨迹;根据样本数据集,获取车辆对应其行驶方向的交通信号灯的变灯时刻;根据车辆对应其行驶方向的交通信号灯的变灯时刻,以及,该交通信号灯在目标时间段的变灯周期,获取车辆对应该交通信号灯的变灯偏移时刻;根据车辆对应该交通信号灯的变灯偏移时刻,获取目标路口的交通信号灯之间在目标时间段的相位差。本申请提供的方法可以降低上述相位差的获取难度,提升相位差获取效率,以及,地图数据处理方法的可用性。
