The invention discloses a vehicle track data processing method. The method comprises the following steps: S1, collecting vehicle track data through a vehicle-mounted GPS device; s2, preprocessing the vehicle trajectory data to obtain corrected vehicle trajectory data; s3, associating the road network data, the traffic element information and the regional POI information with the corrected vehicle trajectory data to obtain geographic space data; s4, performing gridding slicing on the geographic space data, and performing matching and fusion on slices and vehicle track points to obtain vehicle track information; according to the method, the vehicle track data are corrected and associated with other feature information, so that the vehicle track information with rich features is constructed, and the abnormal driving behaviors of the vehicle can be analyzed and recognized conveniently.
本发明公开了一种车辆轨迹数据处理方法,包括以下步骤:S1、通过车载GPS设备采集车辆轨迹数据;S2、对车辆轨迹数据进行预处理,得到修正车辆轨迹数据;S3、将路网数据、交通要素信息和区域POI信息与修正车辆轨迹数据关联,得到地理空间数据;S4、对地理空间数据进行网格化切片,将切片与车辆轨迹点进行匹配和融合,得到车辆轨迹信息;本发明通过对车辆轨迹数据进行修正,并关联其他特征信息,构建成特征丰富的车辆轨迹信息,便于对车辆异常行驶行为进行分析和识别。
