The invention discloses a suspected fake-licensed vehicle portraying method based on ETC (Electronic Toll Collection) portal data, which belongs to the technical field of expressway traffic management and comprises the following steps of: S1, extracting a main data field from a database generated by an ETC portal; s2, according to the time sequence of the recorded data of the vehicles with the same license plate, a track recording sequence of the vehicles is formed, and then the track recording sequence is judged to be in an abnormal sequence condition or a normal sequence condition according to the upstream and downstream portal association relation; and S3, distinguishing three types of equipment failure, normal vehicles and suspected fake-licensed vehicles to form a suspected fake-licensed vehicle portrait. According to the method, highway traffic big data is fully mined, the method is applied to illegal fake-licensed vehicle identification and portrait, the effectiveness of mass data is realized, the initiative of traffic management and monitoring can be improved, and the limitation of traffic police routine inspection and the labor cost are reduced.

    本发明公开了一种基于ETC收费门架数据的疑似套牌车辆画像方法,属于高速公路交通管理技术领域,包括以下步骤:步骤S1、从ETC收费门架生成的数据库中,提取主要数据字段;步骤S2、依据同一牌照车辆的记录数据的时间先后顺序,形成该车辆的轨迹记录序列,然后根据上下游门架关联关系将轨迹记录序列判断为顺序异常或顺序正常两类情况;步骤S3、区分设备故障、正常车辆和疑似套牌车辆三种类型,形成疑似套牌车辆画像。本发明充分挖掘高速公路交通大数据,应用于对违法套牌车辆识别和画像,实现了海量数据的效用性,能够提高交通管理和监测的主动性,减轻交警例行检查的局限性和人工成本。
