AVI (Automatic Vehicle Identification) is a technology used to automate the identification of vehicles. Here’s how it works and its key applications:
- System Components: AVI systems typically consist of an on-board transponder (a small electronic device installed in the vehicle) and roadside receivers. The transponder communicates with the receiver as the vehicle passes by, enabling the system to identify the vehicle automatically.
- Applications:
- Electronic Toll Collection: AVI is widely used in electronic toll collection systems, allowing vehicles to pass through toll booths without stopping. The toll fee is automatically deducted from the driver’s account based on the vehicle’s identification.
- Stolen Vehicle Detection: Law enforcement agencies use AVI systems to identify and track stolen vehicles. When a vehicle equipped with a transponder passes a receiver, its identification information is checked against a database of stolen vehicles.
AVI systems improve efficiency in various transportation applications, enhancing convenience and security.
