The invention belongs to the technical field of data processing, and particularly relates to a vehicle space-time trajectory data processing method based on a smart city, and the method comprises the following steps: S100, obtaining trajectory coordinate points, and forming a moving trajectory; step S200, track denoising: performing judgment according to the moving track of the object, and identifying and removing noisy points in the moving track; step S300, track segmentation: segmenting according to the de-noised moving track of the object; step S400, track map matching is carried out; step S500, obtaining real-time road network traffic conditions according to the matching track and the track segmentation information; according to the method, the noisy points of the vehicle moving track collected by the GPS can be effectively removed, the moving track of the vehicle is more accurate, meanwhile, the moving track of the vehicle is segmented, the moving track is matched with the road network, and therefore the real-time traffic condition of the road network is effectively known.

    本发明属于数据处理技术领域,具体涉及一种基于智慧城市车辆时空轨迹数据处理方法,包括有以下步骤:步骤S100:获取轨迹坐标点形成移动轨迹;步骤S200:轨迹去噪,根据该对象的移动轨迹进行判定,识别并去除移动轨迹中的噪点;步骤S300:轨迹分段,根据该对象的去噪后的移动轨迹进行分段;步骤S400:轨迹地图匹配;步骤S500:根据匹配轨迹和轨迹分段信息,获得实时的道路路网交通状况;本发明能够有效的去除GPS采集的车辆移动轨迹的噪点,使车辆的移动轨迹更加准确,同时将车辆的移动轨迹进行分段,并将移动轨迹与道路路网进行匹配,从而有效的获知实时的道路路网交通状况。
