Multi-lane free-flow tolling systems (MLFF) are designed to keep traffic moving! TollChecker^freeflow is a future proof toll enforcement system with a unique design. Unlike any other system worldwide TollChecker^freeflow requires just a single gantry per location and operates without the need for in-road equipment such as loops and sensors.

This means that the system can be installed and maintained with minimum costs and disruption to road users. Precise 3D vehicle classification calculates the correct fee regardless of the speed/direction of the vehicle. Even vehicles driving parallel, overtaking, tailgating or changing lanes are identified. Vehicles not fitted with an OBU/tag can be verified using ALPR, minimizing revenue loss.
