The invention provides a data processing method and system for vehicle passing information, and the method comprises the steps: carrying out the extraction and cleaning of the tracks of all historical passing vehicles in a leak detection interval, and obtaining the historical vehicle tracks which completely pass through the leak detection interval; matching the obtained historical vehicle tracks which completely pass through the leak detection interval with alternative paths of the leak detection interval, obtaining real driving tracks of all vehicles with complete tracks through matching, and adding track labels of samples into an original data set; performing calculation according to a feature extraction method reflecting vehicle similarity, and then performing normalization processing on all features to obtain feature spaces of all samples; and constructing a sample set based on vehicle similarity by combining the actual driving path label obtained by matching, and taking the sample set as a data basis of a track discrimination model based on KNN.
本发明提出了一种车辆通行信息的数据处理方法及系统,包括:对漏检区间内所有历史通过车辆的轨迹进行提取和清洗,获取完整经过漏检区间的历史车辆轨迹;将得到的完整经过漏检区间的历史车辆轨迹与漏检区间备选路径相匹配,通过匹配获取所有轨迹完整车辆的真实行驶轨迹,并将样本的轨迹标签添加到原始数据集中;按反应车辆相似性的特征提取方法进行计算,然后将所有特征进行归一化处理,得到所有样本的特征空间;结合匹配得到的实际行驶路径标签,构建出基于车辆相似性的样本集,作为基于KNN的轨迹判别模型的数据基础。
