GPS-GPRS Control and Tracking System for Taxi Vehicle

The market still has a high desire for taxis today. However, a number of problems exist that prevent the taxi industry from growing in a healthy way, including the poor pay of taxi drivers and the growing difficulty in hailing cabs. This paper exploits the speedy development of data communication technology and data processing technology, we can acquire taxi vehicles' real time operation standing through the large-scale taxi GPS trajectories. The system is based on taxi monitoring terminal device which takes STM32 board as the core, combining GPS, GPRS and taximeter was proposed. This solution will show the superiority of STM32 microcontroller, which is high speed, low-power and has rich interface which can send the position of each taxi geographical coordinates as well as other important data in a server connected via Internet. The data collected from this system presents a good analysis of the supply and demand indicators of the taxi industry. As a result, the problems and some solutions for the improvement of this sector are presented.
