The embodiment of the invention provides a bus midway station position detection method and system, and the method comprises the steps: enabling the station position in a to-be-detected bus line to bemapped to a bus track grid according to the line information of the to-be-detected bus line; and obtaining a retardation probability corresponding to each specific grid contained in the bus track grid, and screening out stations with correct positions in the to-be-detected bus line based on the retardation probability, wherein the retardation probability is used for indicating the proportion of the bus staying on the specific grid. The confirmed correct original bus stop position is selected out through the retardation probability, the bus midway stop station with the wrong position is efficiently and cheaply detected, and the possible correct station position is recommended so that measures are taken for correcting the station with the wrong position, and the accuracy of line network data is ensured.

    本发明实施例提供一种公交中途站点位置检测方法及系统,该方法包括:根据待检测公交线路的线路信息,将待检测公交线路中的站点位置映射到车辆轨迹网格中;获取车辆轨迹网格所包含的每个特定网格对应的阻滞概率,基于阻滞概率筛选出待检测公交线路中位置正确的站点;其中,阻滞概率用于指示公交车辆在特定网格上停留的比例。本发明实施例通过阻滞概率筛选出确信正确的原有公交站点位置,高效廉价的检测位置错误的公交中途站点,并推荐出可能正确的站点位置,以便对位置错误的站点采取措施进行纠正,保证线网数据的准确性。
