Why in News Union Minister for Road Transport and Highways Nitin Gadkari inaugurated India’s first Multi-Lane Free Flow (MLFF) barrier-less tolling system at the Chorayasi Toll Plaza on NH-48 (Surat-Bharuch section), Gujarat on May 1, 2026. The Ministry on May 11, 2026 confirmed the end-2026 rollout target for MLFF across the National Highway network.

Background: India’s Tolling Evolution

Phase Year Mechanism
Manual cash tolling 1990s-2014 Operator-collected cash, paper receipts
FASTag introduced 2014 RFID-based electronic toll collection (ETC)
FASTag mandatory February 2021 All vehicles required to use FASTag at toll plazas
Hybrid FASTag + cash 2021-2025 Mixed lanes; long FASTag queues during peak
MLFF launched May 1, 2026 Barrier-less; ANPR + FASTag

FASTag transformed toll collection but still depended on physical barriers and stop-go interactions. A 2024 IIM-Bangalore study estimated that even with FASTag, the average vehicle lost ~7 minutes per major toll plaza during peak hours.

What is MLFF?

Multi-Lane Free Flow is a tolling architecture where:

  • There are no physical barriers – vehicles do not slow down or stop
  • Tolls are deducted automatically as the vehicle drives through under a gantry
  • Two parallel identification systems are used:
    1. FASTag (RFID) – the existing NPCI-managed electronic toll system
    2. Automatic Number Plate Recognition (ANPR) – cameras read the number plate; the system queries the VAHAN database to identify the vehicle
  • For vehicles without a valid FASTag balance or wallet, an E-Notice is issued to the registered owner via the Parivahan portal
Component Function
Overhead gantry Hosts cameras and antennas
ANPR cameras Read number plates as vehicle passes
RFID antenna Reads FASTag, deducts toll
Central toll processor Matches plate to FASTag account; processes payment
E-Notice system Issues invoice for missed payments

The Chorayasi Pilot: Day-1 Numbers

Parameter Detail
Location Chorayasi, NH-48 (Surat-Bharuch), Gujarat
Inaugurated by Nitin Gadkari, Minister of Road Transport and Highways
Date May 1, 2026
Day-1 vehicle throughput ~41,500 vehicles
Average passage time Continuous flow (no stop)
System uptime Day-1 Near 100% reported

NH-48 is the busiest National Highway corridor in India – connecting Delhi to Mumbai (and onward to Chennai as NH-48 was renumbered from the older NH-8 and NH-4 system in 2010).

The Rollout Plan

Phase Timeline Scope
Phase 1 2026 25 NH toll plazas with MLFF – mostly high-traffic golden quadrilateral and expressway plazas
Phase 2 FY 2026-27 ~200 plazas under MLFF; spans North-South and East-West corridors
Target End of 2026 MLFF operational across the entire NH network

Implementing agency: National Highways Authority of India (NHAI) – a statutory body under the NHAI Act, 1988, functioning under the Ministry of Road Transport and Highways (MoRTH).

Why MLFF Matters

1. Travel Time and Fuel

A NITI Aayog 2023 brief estimated that ~Rs 1.45 lakh crore is lost annually in India due to traffic congestion. Toll-plaza idling alone contributes significant fuel burn and emissions.

2. Logistics Cost Competitiveness

India’s logistics cost is ~13-14% of GDP (vs ~8% in OECD economies). The National Logistics Policy 2022 targets bringing this to single digits by 2030. Smoother tolling is part of that ecosystem – alongside PM Gati Shakti, dedicated freight corridors, and multi-modal logistics parks.

3. Emissions

NH-48 alone reportedly accounts for over 3 lakh tonnes/year of CO2 at toll-plaza idling under the older system. MLFF should cut this substantially.

4. Compliance and Revenue

Toll evasion – through unregistered vehicles, expired FASTags, or queue-jumping – is harder under ANPR-backed MLFF. The E-Notice system creates a legally enforceable post-pay path.

Concerns and Implementation Issues

Concern Detail
Privacy ANPR creates a passive movement record. Data protection under the DPDP Act, 2023 needs explicit governance.
ANPR error rate Worn or non-standard plates can cause misreads. Day-1 reports suggest a low but non-zero error rate.
Dispute redress E-Notice recipients must have a smooth appeal mechanism, especially for vehicles wrongly identified.
Cyber security Centralised database = high-value target.
FASTag balance Drivers may not know they have insufficient balance until they receive an E-Notice.

UPSC Relevance

GS Paper 3 – Economy and Infrastructure

  • National Highways and transport infrastructure
  • Logistics cost competitiveness; National Logistics Policy 2022
  • PM Gati Shakti National Master Plan (2021)

GS Paper 2 – Governance

  • NHAI as a statutory body
  • DPDP Act, 2023 and government surveillance powers
  • Public service delivery digitisation

Mains Angles

  1. “Reducing logistics cost is critical for India’s manufacturing competitiveness.” Discuss with reference to recent reforms.
  2. Examine the privacy implications of large-scale ANPR-based road infrastructure.
  3. Evaluate the rollout of PM Gati Shakti and its convergence with other infrastructure schemes.
