Automated vehicle location (AVL) systems

Definition

Automated vehicle location (AVL) systems are technologies that use GPS, cellular networks, or other positioning methods to track the location of vehicles in real-time. These systems collect data on vehicle positions and can transmit this information to central databases for analysis and monitoring, providing crucial support for incident detection and response efforts.
