The invention discloses a road experience speed determination method, and belongs to the field of data processing. The method comprises the following steps: according to a road ID of each track point, extracting a road section through which a track adjacent to each track point passes, and obtaining a road ID sequence corresponding to each track point; grouping and sequencing the speed values of the track points corresponding to the track point IDs associated with the road center points according to the road ID sequences to obtain a speed value list of the track points corresponding to the road center point IDs and the road ID sequences; and carrying out screening statistics on the speed values in the speed value list to obtain the experience speed of the road. According to the method, the concept is simple, the experience speed can be applied to all roads, the experience speed can also be applied to vehicles when only road-level positioning exists, and advanced deceleration, stable speed jump and smooth speed change during acceleration and deceleration are achieved before ramp entering, left turning and right turning, and the track utilization rate is high; and meanwhile, the influence of track points such as parking, traffic jam and slow speed on the empirical speed is also reduced.

    本申请公开了一种道路经验速度确定方法,属于数据处理领域。该方法包括根据每个轨迹点的道路ID,提取与每个轨迹点相邻近的轨迹所经过的道路段,得到每个轨迹点对应的道路ID序列;对道路中心点相关联的轨迹点ID对应的轨迹点的速度值按照其道路ID序列进行分组排序,得到与道路中心点ID和道路ID序列对应的轨迹点的速度值列表;对速度值列表中的速度值进行筛选统计,得到该段道路的经验速度。本申请概念简单,所有道路均能够用上经验速度,并且在只存在道路级定位时,车辆也能使用经验速度,实现在进匝道、左转、右转前提前减速,速度稳定跳变少,加减速时速度平滑变化,轨迹利用率高;同时还降低了停车、堵车、慢速等轨迹点对经验速度的影响。
