How Multi-Lane Free Flow Works.

Detection, identification and transaction technologies work together while vehicles continue moving through the tolling zone at highway speed.

MLFF Operational Sequence Six connected stages—from detection to confirmation
Barrierless Cashless Contactless
Vehicle detected by radar while entering an MLFF tolling zone
01 Radar

Vehicle Detection

Radar detects a vehicle entering the configured multi-lane tolling zone.

Vehicle presence detected
FASTag RFID reader capturing vehicle tag information
02 RFID / FASTag

FASTag Reading

The RFID reader captures the vehicle’s FASTag information while it remains in motion.

Contactless identification
ANPR camera capturing a vehicle registration plate
03 ANPR Camera

ANPR Capture

The ANPR camera captures the vehicle registration plate for identification and verification.

Key Benefits

Built to Keep Traffic Moving.

Multi-Lane Free Flow removes conventional stopping points from the tolling journey, supporting smoother traffic movement and more efficient highway operations.

Zero Traffic Bottlenecks

Vehicles continue through the tolling zone without stopping at physical booths or barriers.

Lower Emissions & Fuel Savings

Reduced stopping, idling and acceleration can support lower fuel usage and vehicle emissions.

Cost Efficiency

Automated transactions and barrierless infrastructure support more efficient tolling workflows.

High-Speed Detection

Radar, RFID and ANPR technologies support vehicle detection and identification while traffic remains in motion.
