GS-3: Infrastructure: Roads.

Context: Recently, the Union Ministry of Road Transport & Highways launched India’s first Multi-Lane Free Flow (MLFF) barrier-less tolling system at the Chorayasi Toll Plaza on the Surat–Bharuch section of NH-48 in Gujarat.

About MLFF (Multi-Lane Free Flow)

• MLFF is a next-generation digital tolling system that enables barrier-free movement, faster traffic flow, and efficient highway operations. 

• It is an upgrade over the FASTag-based Electronic Toll Collection (ETC) introduced in 2014.

• Vehicles do not stop at toll plazas; tolls are collected while vehicles remain in motion. 

• It uses FASTag (RFID-based system) and ANPR (Automatic Number Plate Recognition) for automatic toll deduction. 

• The system is integrated with the VAHAN (National Vehicle Registry) for verification and enforcement. 

• It generates electronic transaction records and notifications, ensuring transparency. 

• Implemented by National Highways Authority of India through Indian Highways Management Company Limited.

Key Features of MLFF

• Barrier-less & Continuous Movement: Eliminates toll booths and boom barriers, ensuring uninterrupted vehicle flow without stoppage. 

• Dual Identification & Validation: Combines FASTag (RFID) and ANPR-based number plate recognition for accurate and reliable vehicle identification. 

• Real-Time Automated Toll Collection: Enables seamless toll deduction with instant transaction recording and user notification. 

• Integrated Technology Framework: Links toll collection system with VAHAN database for vehicle verification and enforcement. 

• Automated Violation Detection & Enforcement: 

o Detects invalid FASTag, mismatched vehicle registration number (VRN), or non-payment cases 

o Issues e-notices with violation details 

o Provides 72-hour window for payment (only base toll applicable) 

o Beyond 72 hours → double toll penalty 

o Includes grievance redressal mechanism with time-bound resolution 

• Regulatory Support Measures: 

o Mandatory High Security Registration Plates (HSRP) for accurate ANPR functioning.

o “One Vehicle, One FASTag” policy to prevent misuse.

• Reduced Manual Intervention: Minimises human involvement, reducing errors and improving efficiency.

Significance of MLFF

• Improved Traffic Flow & Reduced Congestion: By eliminating stoppages at toll plazas, MLFF significantly reduces bottlenecks and improves highway traffic movement. 

• Enhanced Time, Fuel Efficiency & Environmental Benefits: Continuous vehicle movement reduces travel time, lowers fuel consumption, and minimizes delays caused by toll queues; reduced idling at toll plazas leads to lower vehicular emissions, contributing to environmental sustainability. 

• Better User Convenience & Ease of Living: MLFF improves commuter experience by reducing waiting time and creating a smoother, stress-free travel environment. 

• Boost to Logistics & Ease of Doing Business: Faster and more predictable movement of goods enhances logistics efficiency, benefiting transporters, fleet operators, and businesses. 

• Improved Toll Revenue Efficiency: The system reduces leakages, enhances compliance, and ensures accurate toll collection through digital monitoring. 

• Digital Governance & Future-Ready Infrastructure: Aligns with global best practices and supports development of smart highways. 

• Scalable Nationwide Expansion: Planned rollout across all four-lane and above highways, with nationwide implementation targeted by March 2029.
