What technology does Automatic Vehicle Location (AVL) primarily use?

Automatic Vehicle Location (AVL) primarily relies on GPS tracking technology to determine the precise location of vehicles in real-time. GPS, or Global Positioning System, utilizes a network of satellites that send signals to GPS receivers installed in vehicles. By triangulating these signals, the system can accurately calculate the vehicle's geographic position, speed, and direction of travel.

The use of GPS in AVL systems enables a variety of applications, such as fleet management, route optimization, and real-time traffic monitoring. This technology facilitates improved operational efficiency and safety by providing timely data about vehicle locations and movements.

While alternatives like RFID, Wi-Fi positioning, and Bluetooth beacons have their own applications in tracking and location services, they do not offer the same level of accuracy and real-time capability for larger geographic areas as GPS does in the context of vehicle location tracking. Thus, GPS tracking is the most suitable technology for Automatic Vehicle Location systems.
