Intelligent vehicle GPS position terminal came in order to solve the traffic problems, which is an important component of intelligent bus system. Under the advantageous background of urban traffic, we must forcefully develop public transport business in order to alleviate the congestion of urban traffic. The construction of intelligent bus system can improve the managing methods of the bus company and improve the operating efficiency and service levels of the public transportation system which is an important development step for urban public transport.In this paper, referring to a lot of literatures and designs and combinating of advanced technology on GPS, GPRS, bus terminal design and implementation controlled by MCU are proposed, including hardware design, software code writing, debugging machine and so on. The function of the terminal is described in detail.the corresponding design and a specific hardware design schematics are gram flow chart are drawn thoroughly in software design.the main modules function is proposed.Finally, the terminal is tested.This design is stable and easy to use with real-time information be sent continuously to the monitoring center to locate t
