Seamless Road Tolling

Automating payment, reducing or eliminating waiting times, saving cost on infrastructure and personnel. Just a few of the benefits of having automatic license plate recognition integrated into your tolling project. The Carmen® ANPR/ALPR software is powerful and versatile enough to fit any tolling project, from small private roads to multi-lane highways.

Fast, Touch-Free, Automated Tolling

Integrating Carmen® is the first step in creating fully touchless, pay-by-plate tolling systems that run license plate information against databases related to vehicle categories, payment, and more. The software recognizes and analyzes plates from around the globe with speed and accuracy. Single-lane roads to multi-lane highways, the Carmen® license plate recognition software handles them with the same efficiency.

With add-ons like Carmen® MMR (Make and Model Recognition with Color and Category data), and the automatic dangerous goods recognition (ADR/E-ADR, IMO) engine, you can create alerts for bridge/tunnel/ferry operators when vehicles requiring special attention, like an overweight truck or an LPG car, is approaching the gates.

Practical Uses of CARMEN® in Tolling

Projects You Can Build on ANPR/ALPR Technology:

  • Highway tolling
  • Automatic road toll payment
  • Private road usage
  • Vehicle categorizing
  • Tolling for bridges/tunnels
  • Tolling for ferries
