Context:

Recently, The National Highways Authority of India (NHAI) has signed an agreement with ICICI Bank to implement the country's first comprehensive Multi-Lane Free Flow (MLFF) tolling system at Choryasi Fee Plaza in Gujarat on NH-48. This landmark agreement marks a significant milestone in the evolution and modernization of tolling in India.

About Multi-Lane Free Flow (MLFF):

The Multi-Lane Free Flow (MLFF) tolling system is a barrier-free, electronic toll collection method that eliminates the need for vehicles to stop at toll plazas.

·        It uses RFID technology, FASTag, and ANPR (Automatic Number Plate Recognition) cameras to identify vehicles and automate toll payments.

·        It can also function without tags, using only video-based license plate recognition, as implemented in Stockholm for congestion charging.

Key Technologies used: 

• RFID (e.g., FASTag): A passive tag on the vehicle’s windscreen is read by gantry-mounted RFID readers. The toll amount is automatically deducted from the linked bank account or wallet, enabling seamless, contactless tolling.
• ANPR: High-resolution cameras capture the vehicle's license plate. Optical Character Recognition (OCR) software converts this image into text to identify the vehicle. ANPR is crucial for detecting non-FASTag vehicles or enforcing violations in open-road tolling setups.

How It Works:

• Gantry-Based System: Overhead gantries with RFID readers and ANPR cameras are installed on highways.
• Vehicle Identification: RFID scanners read the vehicle’s FASTag, and ANPR cameras verify the license plate.
• Automated Deduction: The toll is automatically deducted from the FASTag-linked account without requiring the vehicle to stop.
• Free Flow Movement: Vehicles continue moving at highway speeds, creating a seamless tolling experience.

Benefits:

• Reduces traffic congestion and travel time
• Improves fuel efficiency and lowers emissions
• Increases transparency in toll collection
• Supports smart, tech-enabled infrastructure development

NHAI will roll out MLFF at 25 toll plazas in FY 2025–26.

Conclusion:

The implementation of MLFF will pave the way for its adoption nationwide, transforming the way tolls are collected on Indian highways. With this innovative system, India is taking a significant step towards a more efficient and technologically advanced transportation network
