What is AVL?

An automatic vehicle locator (AVL) is a device that makes use of the Global Positioning System (GPS) to enable a business or agency to remotely track the location of its vehicle fleet by using the Internet. These devices combine GPS technology, cellular communications, street-level mapping, and an intuitive user interface, with the ostensible goal of improving fleet management and customer service. For example, a company using an AVL system is able to pinpoint the longitude, latitude, ground speed, and course direction of a given vehicle. The vehicle's location can be quickly found and it could be rerouted to provide timely delivery to a nearby customer. AVL systems also enable companies to structure delivery routes more efficiently by compiling a database of vehicle information, including location of customers in relation to established delivery routes.

How Does AVL work

AVL systems generally include a network of vehicles that are equipped with a mobile radio receiver, a GPS receiver, a GPS modem, and a GPS antenna. This network connects with a base radio consisting of a PC computer station as well as a GPS receiver and interface. GPS uses interactive maps rather than static map images on the Web. This means users can perform conventional GPS functions such as zoom, pan, identify and queries.

Why use AVL?

AVL systems can be used to increase the accountability of field personnel and boost the efficiency of a company's dispatching procedure. Dispatchers can get a real-time snapshot of driver adherence to a route, provide customers with an estimated time of arrival, and communicate directly with drivers. Public safety agencies, such as police department or fire departments, can use AVL technology to improve response times by being able to dispatch the closest vehicles for emergencies. Typical uses of AVL technology include the following:

  • Routing
  • tracking location, speed, stops
  • monitoring vehicle functions like engine temperature, use of cargo doors, oil pressure
  • communicating with drivers by text, voice, and data transfer
  • verifying employee time cards
  • creating employee accountability
  • discouraging unauthorized use of vehicles
  • decreasing overtime
  • discouraging excessive speeding
  • cutting fuel costs
  • recovering lost or stolen vehicles
  • monitoring hours of operation

Who would benefit from AVL?

Anyone who manages a fleet of vehicles or who wants to keep track of valuable assets would benefit from an AVL system. This includes service vehicles, delivery vehicles, semi-trucks, rental vehicles, heavy equipment, and trailers.
