Abstract Travel Information Service Systems is one of important part of Intelligent Transportation System, In order to solve the problem of fuzzy place name matching in Travel Information Service Systems, The research of cluster analysis in spatial data mining methods was studied, and proposed a model and algorithm for fuzzy place name matching based on CURE clustering method. Finally, We verify the algorithm of this paper based on Guangzhou electronic map, the experiment proved that it can effectively improve the speed of spatial information retrieval and fuzzy place name matching rate.
