摘　　要：路网数据融合是路网数据更新以及提升数据质量的重要方法之一。而路网数据融合的关键技术在于路网匹配。结合路网数据源的特点,提出了一种顾及路段和结点拓扑关系,基于语义、几何和拓扑多种相似度量指标的路网匹配算法。通过实验表明,该算法能在不同尺度的路网数据中准确识别出互相匹配的路段,具备可操作性和实用性。Road network data fusion is one of the important methods, which can be used to improve data quality and update data. And the key technology of road network data fusion is the road network matching. According to the characteristics of network data sources, a road network matching algorithm based on geometry, topology and semantics multi similarity measure criteria is proposed, which takes into the consideration of topological relations between the road arcs and the nodes. Experiments show that the algorithm can ac- curately identify the matching road arcs in different scales, and it is operable and practical.
