Which system lists the estimated real-time locations of emergency response units within a service area for dispatch?

• A. Digital map
• B. USNG
• C. AVL system
• D. ANI/ALI

Answer: (C)

Tracking where responders are in real time is the job of the Automatic Vehicle Location system. AVL uses GPS or other reporting from each vehicle to continuously update a map or CAD screen with every unit’s position, status, and sometimes speed, so dispatchers can assign the closest unit, monitor progress, and estimate arrival times. A digital map is just the geographic display and may show units if it’s tied to AVL, but it doesn’t by itself provide real-time tracking. USNG is simply a standardized way to reference locations on a map, not a live tracking system. ANI/ALI handle caller identification and location information for telephone calls, not vehicle tracking. So AVL is the system designed to list estimated real-time locations of emergency response units for dispatch.
