Design And Implement Of Bus Query System Based On Web

With the rapid economic development, there are more and more cars. The speed of cities'road construction is far behind the speed of the process of urbanization. Thus, traffic jams have become one of constraints which affect the development of cities. And public transportation has the advantages of wide coverage, economy and celerity. Therefore, in order to relieve the pressure of the traffic, it is necessary to develop public transportation, promote the level of public transport services, encourage and attract citizens to travel by public transportation. Based on the purpose above, we develop a web-based public transportation system, which provides detailed and comprehensive information for passengers and improves the level of public transport services.this report covers the following aspects: requirement analysis of bus query system through research on passengers'travel activities; general design on system development environment, system objects, design process, functional design ,module design and database design; building mathematic models of bus network through abstracting the sites and lines in the bus network, based on which introduces optimal path algorithms of bus query suitable for three different situation; detail design of query system on requirement analysis, general design and query algorithms of bus network which bases on best network path ; applying three network path algorithms to transfer query of the system successfully; achieving the functions of maintenance of net line, line query, site query and query of landmark locations; testing the system's functions with the experiment statistics of 25 lines and 400 sites in WuHan; analysis of the time and results of bus network path algorithm. And the experiment has justified that the system is user-friendly and the functions of the system are perfect.
