行进车队的地图匹配技术研究

根据车队行进的特点，提出了基于多种路况条件的行进车队地图匹配技术。利用行进车队的整体性和连续性、实际路网的拓扑特性以及车队长径和车队定位点的投影距离、方位角等信息，将行进车队准确地匹配到道路上，解决行进车队在电子地图上的定位跟踪问题。通过实验分析，行进车队的地图匹配技术可适用于不同的路段，并保证了车队定位的实时性和准确性。

Research of map-matching technology for moving fleet

According to the characteristics of moving fleet,the paper proposes the map matching technology for a variety of road conditions.Fully considering the integrity and continuity of the moving fleet,the topological characteristic of the actual road networks,the length of the fleet,and the projected distance and azimuth of the fleet＇s locating point,the technology can have a precise match between the moving fleet and the road.It solves the problem of locating and tracking of the moving fleet on the electronic map.The experiment demonstrates that not only can it be applied into different road sections,but also it guarantees the real-time property and accuracy of the fleet locating.
