Urban Public Transportation Travel Query System is an important subject of Intelligent Transport System. Meanwhile, it is also the future of development trend of Traffic Management system. In order to improve the efficiency of urban public transportation travel query especially in the query of vehicle and driver file information in the city of Harbin, the author using the advanced design concepts and developing technologies to establish a set based on B/S (Browser/Server) structure of urban public transportation travel query system.The article first analyses the two important aspects, namely deck building cars and public transport network constructions, which hinder the rapid development of public transport system of Harbin. At the same time, the article proposed the core idea of building urban public transportation travel query system. This paper puts into the details of theories that related to the process of building a urban public transportation travel query system. It distinguishes the differences between development methods that based on the C/S (Client/Server) and B/S about information architecture in details.Secondly, from the perspective of users, the paper makes an analysis on the needs of Urban Public Transportation Travel Query System in details by using the Object-oriented analysis methodology and then puts out the five basic functional modules. Meanwhile, the paper uses the UML Unified Modeling Language to model use case for the system and then to abstract the classes in the system based on the use case modeling. The relationships and attributes between members within the system are determined by static modeling and dynamic modeling.Finally, the article identifies the system development strategy based on the detailed research and analysis of system that is the system development framework of Struts+Tomcat+MyEclipse+MySQL. The detail functions of Urban Public Transportation Travel Query System are designed and implemented by using this framework. The paper gives the system's directory structure and designing flow chart as well as the system source code of the development process. The development steps and processes of Urban Public Transportation Travel Query System are introduced in details by two samples of subsystems that are the management of vehicle and driver file information subsystems and the bus enquiries subsystems. For the bus enquiries subsystems, the paper describes the traditional shortest path query Dijkstra algorithm deeply. Meanwhile, it also points out the lack of Dijkstra algorithm that is used in the public transport query system and proposes a new matrix improved algorithm based on the Dijkstra algorithm. The computation time in program based on the matrix algorithm is verified faster than traditional Dijkstra algorithm by MATLAB. In order to ensure the safety and reliability of the system, the paper designs the users'rights and verification framework for different users and makes validation tests on the Urban Public Transportation Travel Query System at last.
