The invention discloses an intersection vehicle track point data two-stage joint denoising method based on driving characteristics. The method comprises the following steps: acquiring original track point data of vehicles at a road intersection through data acquisition equipment; track point data in the original track point data are preprocessed; grouping the preprocessed track point data according to vehicle IDs, and associating each vehicle ID with a group of data so as to determine the track point data of each vehicle; for the trajectory point data of each vehicle, a two-stage combined denoising method is adopted for denoising.

本发明公开了一种基于行驶特征的交叉口车辆轨迹点数据两阶段联合去噪方法，包括：通过数据采集设备采集道路交叉口车辆的的原始轨迹点数据；将所述原始轨迹点数据中的轨迹点数据进行预处理；对预处理后的轨迹点数据按照车辆ID进行分组，每个车辆ID关联一组数据，从而确定每个车辆的轨迹点数据；针对每个车辆的轨迹点数据，采用两阶段联合去噪方法进行去噪。
