Zusammenfassung:The invention discloses a data fusion method based on the data of various road detectors. The method comprises the steps: constructing a data fusion flow taking an intermodulation station as a core according to the features and meanings of different highway detector data fields; a two-stage fusion method is innovatively provided; station data self-classification is realized by practicing a data driving concept; carrying out fusion quality evaluation by using a site classification re-correspondence method, a flow correspondence method and the like. Therefore, the fusion tasks of core information and intermodulation data of different sites are realized. The site data abnormal values are eliminated. Therefore, a foundation is laid for future road data fusion work while the data integration degree is improved. 本发明公开了一种基于多种公路检测器数据的数据融合方法,根据不同公路检测器数据字段的特征及含义,构建了以交调站为核心的数据融合流程;并创新地提出了两阶段融合方法,在践行数据驱动理念实现站点数据自分类之外,运用站点分类再对应法、流量对应法等进行了融合质量评估,实现不同站点核心信息与交调数据的融合任务,并剔除站点数据异常值,从而在提高数据一体化程度的同时为日后的公路数据融合工作奠定基础。
