摘要：This paper establishes a dynamic route service framework based on windows socket and .net remoting technology, which ensures the update of extended route service data in time. To improve the quality of urban travel navigation service, the route analysis is extended in several means, including the integration of route service with time information and improving the algorithm in different travel modes. Using the principles of space–time prism concept as a source reference, the problem for choosing the appropriate facility in restrained time cost is discussed. Potential path area model of space-time prism is simplified to find the appropriate facility with a high speed
