摘　　要：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。Based on the long-range transportation RTS system development of Alberta state,canada,an analysis of the factors affecting matching performance,according to the idea of partitioning the road net,the continuity of the vehicle movement combing the historical data,a kind of integrated algorithm based on high precision digital map is proposed.This algorithm can realize the accurate positioning,and the computation load of the algorithm is small,so it can be used in the embedded real-time system.The effectiveness and applicability of this matching algorithm is demonstrated by real road experiments.
