Abstract:

To better monitor the vehicles traveling on roads, and save cost, this article describes a vehicle locating and monitoring system based on the hybrid GPRS/Bluetooth scheme. The system integrates GPS, GIS, the communications technology and the computer technology, and is a mobile vehicle service system . The paper introduces the main technology of integrating GPRS and Bluetooth in the monitoring model. Meanwhile the paper proposes a buffer-based GPS da  ta path matching algorithm,which behaves well in practical engineering applications.

Key words: GPS, vehicle monitoring, GPRS/bluetooth, GIS, map matching
