The invention relates to an expressway network vehicle card inconformity auditing method in the technical field of traffic information. The method comprises the steps of collecting RSU antenna flow data and portal license plate recognition data of an ETC portal regularly every five minutes; respectively acquiring a vehicle license plate number and vehicle characteristic information data, and grouping and comparing the vehicle license plate number and the vehicle characteristic information data according to vehicles to obtain a data set with inconsistent vehicle characteristic information; carrying out cartesian product operation processing, and list data of inconsistency of the same license plate number being listed; for N continuous ETC portals, repeatedly processing each portal in sequence; setting an inconsistent abnormal threshold value, removing the vehicle data which does not reach the set threshold value times, retaining the vehicle data which reaches or exceeds the threshold value, transmitting the abnormal vehicle data to a storage database, and storing the abnormal vehicle data in the storage database. The highway network vehicle card inconformity auditing method providedby the invention has the advantages that the tedious manual searching and comparison of auditing is reduced, the information effectiveness is strong, and the auditing work efficiency can be improved.
本发明涉及交通信息技术领域的一种高速公路路网车卡不符稽核方法,对ETC门架每间隔五分钟定时采集门架的RSU天线流水数据和门架车牌识别数据;再分别获取车辆车牌号和车辆特征信息数据并按车辆进行分组比对,得到上述两者存在车辆特征信息不一致的数据集;再作笛卡尔乘积运算处理,并罗列出同一车牌号不一致列表数据;对连续的N个ETC门架,对每个门架均依次重复处理;设置不一致异常门限阀值,去除未达设置阀值次数的车辆数据,保留达到或超过阀值的车辆数据,将异常车辆数据并将稽查结果传输至存储数据库,本发明能够提供一种减少稽查人工查找比对繁琐、信息实效性强且可提高稽查工作效率的高速公路路网车卡不符稽核方法。
