The invention provides a traffic light total period mining method and device, and relates to the technical field of big data, in particular to the technical field of map navigation. A specific embodiment of the method comprises the steps of extracting a target trajectory feature set based on a historical trajectory data set of vehicles passing through an intersection; based on the target trajectory feature set, determining candidate periods of traffic lights in the intersection; based on the candidate period of the traffic light, determining an intersection candidate period; and determining the traffic light total period of the intersection based on the red-green conflict of the intersection candidate period.
本公开提供了一种红绿灯总周期挖掘方法和装置,涉及大数据技术领域,尤其涉及地图导航技术领域。该方法的一具体实施方式包括:基于经过路口的车辆的历史轨迹数据集,提取目标轨迹特征集;基于目标轨迹特征集,确定路口内的红绿灯的候选周期;基于红绿灯的候选周期,确定路口候选周期;基于路口候选周期的红绿冲突,确定路口的红绿灯总周期。
