The invention relates to a parking analysis method based on a vehicle track, and belongs to the technical field of intelligent traffic, and the method comprises the steps: marking the vehicle passing data of each intersection according to a path coordination direction, and obtaining a plurality of vehicle track data; repairing and complementing the vehicle track data according to the vehicle speed and the vehicle passing data of two intersections adjacent to the missing intersection; extracting the number of intersections through which the same vehicle passes from the two groups of vehicle track data in the adjacent time periods, and performing track connection on the two groups of vehicle track data when the number of the intersections meets a set effective track data volume threshold value to obtain optimal vehicle track data; according to the optimal vehicle track data, the parking condition of each intersection is analyzed in combination with the obtained intersection equipment type and the non-stop passing time of different road sections, and the path parking rate and the intersection continuous traffic rate in the path coordination direction are obtained. According to the invention, the accuracy of two groups of data including the path parking rate and the intersection continuous traffic rate is greatly improved.
本发明涉及一种基于车辆轨迹的停车分析方法,其属于智能交通技术领域,方法包括:将各个路口的过车数据按照路径协调方向进行标记,获得若干车辆轨迹数据;依据车辆速度和与缺失路口相邻的两个路口的过车数据,对车辆轨迹数据进行修复补全;从相邻时段的两组车辆轨迹数据中提取同一辆车通过的路口数量,并在该路口数量满足设定的有效轨迹数据量阈值时,将该两组车辆轨迹数据进行轨迹衔接,获得最优车辆轨迹数据;根据最优车辆轨迹数据,结合获取到的路口设备类型和不同路段的不停车通行时间,对每一路口的停车情况进行分析,获得路径协调方向上的路径停车率和路口连续通车率。本发明极大地提高了路径停车率和路口连续通车率这两组的数据的准确性。
