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).
