Design And Implementation Of Bus Query System Based On Android Platform

At present,urban public transport system is taking an improtant role in our daily life.which is a universal and applicable demand for public transportation information system,and the mobile phone is more and more popular,and it is feasible and convenient to use mobile phone to inquire public transportation information.In this paper,it provides users with faster query speed,higher quality bus information query service.Android smart phone as a platform to design a small private query system for mobile phone query public transport information,basically meet the convenience needs of public transit information access,while the system provides support for public transport services,to encourage and attract people to choose to travel by bus.This paper is based on the UML use case diagram and activity diagram to analyze the demand of public transport information.It designed in the aspect of system objectives,function design,database design,design process and the system development environment.The design of the several aspects of the system,including the bus station,bus transfer query,bus route query,and the corresponding background management.The system transfer times algorithm is a key different from other bus query system in this paper.In this paper,the design of the data has been a unique design,using the adjacency list and view,based on this system to provide support for more than two transfer algorithm.By testing the function of the system,the test results show that the system has friendly interface,perfect function,high use value,and has a huge potential user groups and a broad application prospects.
