城市公交实时位置手机查询系统设计

针对用户选择公交出行时不能准确获知公交车实时位置等信息的问题，对移动互联网在智能交通中的应用进行了探讨。使用百度地图接口技术设计一种基于移动客户端公交实时位置查询系统，并给出了经纬度数据在电子地图中发生偏移的修正方法。用户使用手机或PDA等网络设备进入此查询系统界面，就能随时查询特定线路上公交车辆的实时位置、数量等信息。经测试，该系统具有一定的可行性。

Design of the real-time bus position inquiry system on smart phone

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.
