列车运行途中环境复杂，监控与定位难度较大，由于单一的GPS车载定位会因为地理环境等原因在一定范围和时间内失效或定位不连续，针对这一局限性，采用GPS/DR与电子地图匹配的定位算法不仅克服了GPS信号在盲区间断或失效的缺点，也避免了DR定位误差随时间的不断积累，提高了定位精度和系统的可靠性。可应用于铁路运输安全，为物资押运列车提供优质的监控。

Monitoring and positioning is difficult when Trains is running on the way with complex environment,A single GPS positioning will be discontinuous even disabled because of geographical environment in certain scope, Against the limitations, Using GPS/DR and the positioning of the electronic map matching algorithm, which overcome the faults of interruption or failure for GPS signal in the blind area, also avoid the DR position error accumulated over time, Improves the location accuracy and the reliability of the system. The method Can be applied to the safety of railway transportation, to provide quality monitoring under escort goods train.
