The invention discloses an ETC door frame track data complementing method, which overcomes the problem of low timeliness and accuracy of highway vehicle inspection work caused by easy missing of ETC door frame data in the prior art, and comprises the following steps: obtaining a vehicle driving ETC track group, and identifying a missing track from the track group based on an isolation forest algorithm; for the missing track, key node information in the missing track data is extracted, and a key node track set is obtained; based on a shortest path search algorithm, traversing and filling the missing hub node information between adjacent nodes in the key node track set to obtain a hub node track set; and based on a road section toll station and gate information data table, searching and complementing missing portal data between two adjacent nodes in the hub node track set to obtain vehicle driving complete ETC track data. Complete driving track data of the expressway vehicles can be accurately and efficiently obtained, and the timeliness and accuracy of the expressway vehicle inspection work can be improved.

    本发明公开了一种ETC门架轨迹数据补全方法,克服现有技术中存在的ETC门架数据易缺失,导致高速公路车辆稽查工作的时效性和准确性低的问题,包括以下步骤:获取车辆行驶ETC轨迹组,基于隔离森林算法从轨迹组中对缺失轨迹进行识别;针对缺失轨迹,抽取缺失轨迹数据中的关键节点信息,得到关键节点轨迹集合;基于最短路径搜索算法,遍历并填补关键节点轨迹集合中相邻节点间缺失的枢纽节点信息,得到枢纽节点轨迹集合;基于路段收费站和卡口信息数据表,检索并补全枢纽节点轨迹集合中相邻两节点间缺失的门架数据,得到车辆行驶完整ETC轨迹数据。准确、高效地得到高速公路车辆行驶完整轨迹数据,提高高速公路车辆稽查工作的时效性和准确性。
