As an important part of urban transportation system, urban public transportation system is acting a key role in human living, in social production and in transportation domain .But the inquiry system of public transportation developments in our country is in a comparatively backward level. The general passengers have less way to obtain the information. In order to solve this kind of problem, an inquiry system of public transport based on J2EE is designed.The thesis has introduced the realized functions of entire system in detail. Firstly, the system has realized many inquiry functions. The system can search bus route by the name of business mansion, the number of public transport, ordinary bus station and two arbitrary stations. Secondly, the system uses the shortest path algorithm to find the shortest travel routes between any two stations. Finally, the system provides the functions of consumer message, the bus number managing on the backstage and the consumer managing. The function of consumer message mainly collects suggestions from consumer to modify and perfect the system functions. The function of user managing is to delete user information mainly and revises the fundamental user information. The functions of bus nu
