基于加拿大亚伯达省政府远程运输RTS系统开发，在分析影响地图匹配性能因素的基础上，提出了一种基于高精密

数字地图的综合地图匹配算法，融合了几何匹配算法和路网拓扑结构，充分利用车辆行驶的连续性，结合历史行驶数据选

取投影道路，实现准确定位，且算法计算量小，可用于嵌入式实时系统。通过实际跑车试验证明该匹配算法精度高、效率

好，具有较好的实用价值。-Canada' s Alberta government based on long-range transportation RTS system development, analysis of map-matching on the basis of performance factors, a high-precision digital map based on a comprehensive map-matching algorithm, the integration of the geometric matching algorithm and network topology full use of the continuity of vehicles, combined with historical traffic data selected projection path, to achieve accurate positioning, and the algorithm computation, can be used for embedded real-time systems. Through the actual car tests show that the matching accuracy, efficiency is good, has good practical value.
