The invention provides a method for bus arrival identification and bus uplink and downlink shift division. The method comprises the following steps: S1) obtaining bus GPS data, known bus route stationattribute data and GPS and bus route corresponding relation table data; S2) carrying out data cleaning; S3) clustering the GPS data of the bus stops, and setting auxiliary parameters for buffer judgment; S4) carrying out centroid selection on the single-cluster GPS data; S5) determining shift sequences of the whole bus route in two directions, sorting the bus shift set according to the time sequence, and excluding a non-ascending order set; and S6) verifying whether each shift contains the arrival time of all stations of the line, and if not, supplementing by using an interpolation method. The method has the advantages that the arrival time of the bus can be quickly and accurately identified, the operation direction and shift segmentation of the bus can be effectively determined, and thedata integrity can be better ensured by using the interpolation method.

    本发明提供一种公交车辆到站识别以及车辆上下行班次划分的方法,包括以下步骤:步骤S1)获取公交车辆GPS数据、已知公交线路站点属性数据和GPS与公交线路对应关系表数据;步骤S2)进行数据清洗;步骤S3)将公交站点GPS数据聚类,设定辅助参数进行缓冲判定;步骤S4)对单簇GPS数据进行质心选取;步骤S5)确定整条公交线路两个方向的班次序列,按照时间序列对公交车班次集合进行排序,排除非升序集合;步骤S6)验证每个班次中是否包含线路所有站点的到站时间,如缺少站点,则用内插法进行补充;本发明的优点在于:快速准确的识别公交车辆到站时间,且能有效的确定车辆运营方向及班次切分,运用内插法更能确保数据完整性。
