The invention relates to a vehicle track credible extraction method and system based on ETC portal data, and belongs to the technical field of expressway ETC portal data development and utilization. A database is constructed firstly, and then the similar distance between the target license plate number of a target vehicle of which the track is to be extracted and other license plate numbers in the database is calculated; the method comprises the following steps: acquiring a target license plate number to determine similar license plate numbers of the target license plate number, further constructing a first data set and second data sets, then selectively fusing the first data set and the second data set corresponding to each similar license plate number to obtain a fused data set, and finally performing single travel data splitting on the fused data set to obtain a single travel data set. And a plurality of single travel tracks of the target vehicle in the analysis time period are obtained, so that the vehicle track is credibly extracted, the vehicle moving track path is accurately identified, and a data processing technical basis is provided for improving the charging auditing precision and realizing ETC data development and utilization.
本发明涉及一种基于ETC门架数据的车辆轨迹可信提取方法及系统,属于高速公路ETC门架数据开发利用技术领域,先构建数据库,再分别计算待提取轨迹的目标车辆的目标车牌号与数据库中的其他车牌号的相似距离,以确定目标车牌号的相似车牌号,进一步构建第一数据集合和第二数据集合,然后对第一数据集合和每一相似车牌号对应的第二数据集合进行选择性融合,得到融合后数据集合,最后对融合后数据集合进行单次出行数据拆分,得到目标车辆在分析时段内的若干条单次出行轨迹,从而对车辆轨迹进行可信提取,精准识别车辆运行轨迹路径,为提高收费稽核精度、实现ETC数据开发利用提供数据处理技术基础。
