Abstract:

In daily life, real-time bus position information cannot be accurately acquired, which brings a lot of inconvenience. In order to overcome this problem, the application of mobile internet in the intelligent transportation is discussed, the Baidu map API technique is used to design a realtime bus position inquiry system based on mobile client, and the offset correction method of longitude and latitude data in the electronic map is given. People can use Smart phone or PDA to enter this app to keep track of the location or number information of the bus. This web app is proved to be feasible under test.
