【Abstract】 On the basis of the analysis of the domestic and oversea current status of the city traffic query, the spatial data structure of the implementation for the city query software is presented and the intelligent query searching algorithm based on the network topology structure is put forward in this paper. The intelligent query system of the city traffic route is implemented at last by use of artificial intelligence, geographical information, multimedia technology, and so on. The practical test of the system shows that the query system designed in the method presented by this paper has the characteristics of high speed, multimedia display, convenient maintenance, and powerful commonality.更多还原
