What is Automatic Vehicle Identification (AVI)?

Automatic Vehicle Identification (AVI) is a contactless system used to identify vehicles electronically as they pass through toll plazas or designated monitoring points. These systems use technologies like RFID tags, license plate recognition cameras, and sensors to read data from vehicles without requiring them to stop or slow down.

In Florida, AVI technology is at the core of electronic tolling systems like SunPass and Toll-by-Plate, allowing for seamless toll collection and smarter road management.

 

How Florida Uses AVI for Tolling

Florida’s tolling system has been undergoing a major shift toward cashless tolling over the last decade. This shift is heavily powered by AVI systems that enable:

  • Real-time reading of vehicle data

  • Linking toll usage to driver accounts (SunPass, Toll-by-Plate)

  • Reducing traffic congestion at toll booths

  • Automatic billing based on plate number or transponder data

Major toll roads like Florida’s Turnpike, SR 528, and I-95 Express Lanes use AVI to streamline travel for millions of drivers each year.

 

Key Benefits of AVI for Florida Drivers

Faster, Cashless Travel

Drivers no longer need to carry cash or stop at toll booths. AVI systems automatically register the toll and charge the appropriate account, making commutes faster and more convenient.

Fewer Errors in Toll Processing

With accurate vehicle tracking and plate recognition, there’s less room for human error or lost tickets. It also improves the consistency of billing, especially when transponders are used.

Safer Roads

Reducing the need to stop at toll plazas decreases the risk of rear-end collisions and improves the overall flow of highway traffic.

Better Enforcement and Tracking

AVI systems help detect toll violators by capturing clear images of license plates and matching them to DMV databases. This allows for faster enforcement and collection of unpaid tolls.

Support for Dynamic Pricing

Some toll roads now use variable toll pricing based on real-time traffic. AVI systems allow this to happen efficiently by instantly tracking vehicle volume and speed.

 

Challenges and Concerns

Privacy

Some drivers are concerned about how much data is collected through AVI systems. While the data is primarily used for billing and traffic management, transparency about data usage remains important.

Incorrect Toll Charges

Errors can occur if a license plate is misread or a transponder fails. These can lead to incorrect bills, especially under Toll-by-Plate systems. That’s why it's important for drivers to keep their information up to date with both SunPass and the DMV.

Increased Surveillance

AVI also enables more detailed tracking of vehicle movements, which raises concerns about surveillance and civil liberties. However, these systems are governed by state regulations to prevent misuse.

 

What Florida Drivers Should Know

  • Make sure your SunPass account is linked to your current license plate and vehicle

  • If you receive a Toll-by-Plate bill, pay promptly to avoid fines

  • Report stolen plates or transponders immediately to prevent misuse

  • Review your toll history online periodically to check for billing errors

  • Consider using tamper-proof plate screws to prevent theft or cloning of your license plate
