The invention relates to the technical field of traffic big data, and discloses a lane-level traffic flow statistical method and device, computer equipment and a storage medium, and the method comprises the steps: obtaining a vehicle moving track; inputting the vehicle moving trajectory into a pre-trained auto-encoder model to obtain vehicle trajectory features; using a preset clustering algorithm to determine a cluster to which the vehicle trajectory features belong; determining a lane where a vehicle to which the vehicle track feature belongs is located according to a corresponding relationship between a predetermined cluster and a lane number; and counting the traffic flow corresponding to the lane according to the preset section and the vehicle running trajectory. The auto-encoder model can extract more advanced and fine trajectory features from the vehicle moving trajectory data, so that the clustering result obtained after clustering based on the trajectory features is more accurate, and the accuracy of lane-level traffic flow statistics is improved.
本发明涉及交通大数据技术领域,公开了一种车道级车流量的统计方法、装置、计算机设备及存储介质,其中,方法包括:获取车辆运行轨迹;将车辆运行轨迹输入至预训练的自编码器模型中,得到车辆轨迹特征;采用预设聚类算法确定车辆轨迹特征所属的聚类簇;根据预确定的聚类簇和车道编号的对应关系,确定车辆轨迹特征所属车辆所在车道;根据预设断面和车辆运行轨迹统计车道对应的车流量。由于自编码器模型能够从车辆运行轨迹数据中提取出更加高级和精细的轨迹特征,从而使得基于轨迹特征进行聚类后得到的聚类结果更加准确,进而提高了车道级车流量统计的准确性。
