Design and implementation of real time vehicle tracking system

Tracking systems were first developed for the shipping industries to determine the position of ships and boats in the sea. Initially passive systems were developed to support in tracking and navigation for location-based applications. For the applications that require real time location information of the vehicle, these systems cannot be employed, because they store the location information in the internal storage that can only be accessed when vehicle is available. Recently, Automatic Vehicle Location (AVL) systems are developed and deployed in numerous environments. These systems are capable of transmitting vehicle´s location information in real time. In these systems, the device installed in the vehicle can transmit the location information in real time to a remote data centre, instead of storing into local storage, using some radio network. In this paper, we present the design and implementation of a real time AVL system that incorporates a hardware device installed in the vehicle and a remote Tracking Server (TS).
