Multi-lane free-flow tolling gantry
Multi-Lane Free Flow

Zero-stop tolling with auditable transaction confidence.

MLFF removes booths and barriers. RITAIS adds the missing engineering depth: multi-sensor fusion, edge processing, OFC backhaul, AI operations and clearing integration.

Core promise

No barriers. All lanes. Multi-modal. Automated.

This page is the MLFF overview. Detailed pages own the deep technical material: LiDAR, 4D radar, sensor fusion, transactions, enforcement, field cabinets and use cases.

1

No barriers

Vehicles pass at full highway speed without toll plazas.

2

All lanes

Every lane is tolled simultaneously under a gantry.

3

Multi-modal

Cars, trucks, motorcycles and commercial vehicles are handled.

4

Automated

AI-driven transaction generation with reduced human intervention.

Sensor suite

Four sensing technologies on the gantry.

RFID reads account identity, ANPR captures the plate, 4D radar tracks motion and LiDAR generates 3D geometry. The fusion engine converts these inputs into one legally defensible vehicle record.

Integrated architecture

MLFF is not only a gantry. It is a three-tier operating system.

RITAIS connects field devices to regional operations and national clearing so every vehicle event can become an auditable transaction, operational alert or analytics signal.

Why RITAIS MLFF
Why RITAIS MLFF

Proven sensor stack, all-weather operation and standards readiness.

The MLFF architecture is designed around four ideas: no single point of sensor failure, radar fallback in adverse weather, standards-compliant interoperability, and AI-native digital-twin operations.
