The invention discloses an expressway flow feature extraction method and system, a medium and electronic equipment, and the method comprises the steps: obtaining and preprocessing historical vehicle charging track data in a preset time period on an expressway where charging nodes are missing, and obtaining to-be-analyzed historical vehicle charging track data; according to the to-be-analyzed historical vehicle charging track data, calculating node correlation parameters of each charging node on the expressway and the spatially adjacent charging node of the charging node; according to the node correlation parameters, performing secondary data completion processing on the historical vehicle charging trajectory data to be analyzed to obtain target historical vehicle charging trajectory data; and calculating a flow distribution set of each toll collection node on a path in the target historical vehicle toll collection track data, and taking the node correlation parameter of each toll collection node and the flow distribution set as the flow characteristics of the expressway. Therefore, by adopting the embodiment of the invention, the accuracy and comprehensiveness of the flow data can be improved, and accurate data support is provided for traffic control measures.
本申请公开了一种高速公路的流量特征提取方法、系统、介质及电子设备,方法包括:获取并预处理存在收费节点缺失的高速公路上预设时间段内的历史车辆收费轨迹数据,得到待分析历史车辆收费轨迹数据;根据待分析历史车辆收费轨迹数据,计算高速公路上每个收费节点与其空间相邻收费节点的节点相关性参数;根据节点相关性参数,对待分析历史车辆收费轨迹数据进行二次数据补全处理,得到目标历史车辆收费轨迹数据;计算目标历史车辆收费轨迹数据中路径上的各收费节点的流量分布集合,将每个收费节点的所述节点相关性参数与流量分布集合作为高速公路的流量特征。因此,采用本申请实施例,可提高流量数据的准确性和全面性,为交通管控措施提供精准数据支撑。
