NHAI Successfully Launches Multi-Lane Free Flow Tolling System at Manoharpura Toll Plaza on the Delhi-Jaipur Section of NH-48

---

1. At a Glance

• Multi-Lane Free Flow (MLFF) is a barrier-less electronic tolling model that allows vehicles to pass through toll plazas at highway speed without stopping — eliminating conventional boom-barriers and manual lanes. [1]
• It integrates Automatic Number Plate Recognition (ANPR) with FASTag-based Electronic Toll Collection (ETC) for fully automated, contactless fee deduction. [1][2]
• UPSC relevance: sits at the intersection of GS-III (Infrastructure, Transport, Technology) and digital governance; tests knowledge of FASTag ecosystem, GNSS, and NHAI's mandate under the National Highways Act.
• India's rollout trajectory — Gujarat → Delhi → Rajasthan — signals a nationwide shift away from physical toll booths, with ~25 plazas targeted in FY 2026-27. [3]

2. Why in the News

• 1 July 2026: NHAI launched MLFF at Manoharpura Toll Plaza on the Delhi-Jaipur section of NH-48, Rajasthan — the second MLFF plaza on this corridor. [1]
• 19 June 2026: NHAI had launched Rajasthan's first MLFF at Daulatpura Toll Plaza on the same NH-48 corridor. [4]
• 2 May 2026: India's first MLFF system launched at Chorayasi Toll Plaza, Surat-Bharuch section of NH-48, Gujarat, recording ~41,500 vehicles on Day 1. [2]
• NHAI also plans to transition Shahjahanpur Toll Plaza (third on the Delhi-Jaipur section) to MLFF imminently. [1][4]

3. Background & Evolution

Year	Milestone
Pre-2014	Manual cash-based toll collection; long queues; leakage
2014–16	Introduction of FASTag (RFID-based) under NHAI/IHMCL; hybrid FASTag lanes
2021	100% FASTag mandate from 16 Feb 2021 for four-wheelers — all lanes declared FASTag lanes
2022	NHAI invites global Expression of Interest (EoI) for GNSS-based ETC within FASTag ecosystem [5]
2023	Union Minister Nitin Gadkari emphasises GNSS technology for modernising toll collection [6]
2026 (May)	India's first MLFF operational at Chorayasi, Gujarat (NH-48) [2]
2026 (Jun)	Rajasthan's first MLFF at Daulatpura, NH-48 [4]
2026 (Jul)	Second Rajasthan MLFF at Manoharpura, NH-48 [1]

• Predecessor systems: Manual toll → Dedicated FASTag lanes → Hybrid lanes → 100% FASTag mandate → MLFF (next generation).
• NHAI's MLFF rollout occurs within the broader GNSS-based ETC framework, where a hybrid model (RFID + GNSS) is envisaged simultaneously. [5]

4. Core Static Facts

Definitions & Terminology

• MLFF (Multi-Lane Free Flow): Tolling without physical barriers; vehicles transact at normal highway speed.
• ANPR: Camera-based system that reads vehicle number plates for identity verification.
• FASTag: RFID tag affixed to windshield, linked to prepaid/bank account; deducted automatically at toll.
• E-Notice: Electronic notice issued if FASTag balance insufficient at the time of passing; 72-hour window to pay, else double toll penalty applies. [1][2]
• GNSS-based ETC: Satellite navigation-based tolling (planned parallel track) — vehicles charged based on distance travelled on National Highways. [5]

Implementing Authority

Parameter	Detail
Nodal Ministry	Ministry of Road Transport & Highways (MoRTH)
Implementing Agency	NHAI (National Highways Authority of India)
Enabling statute	National Highways Authority of India Act, 1988; National Highways Fee Rules, 2008
Payment redressal portal	nhfeenotice.parivahan.gov.in; Rajmargyatra App [1]

Key Numbers

• Day-1 traffic at Chorayasi (India's first MLFF): ~41,500 vehicles [2]
• Penalty for non-payment: 2× normal toll rate (after 72-hr E-Notice period) [1]
• FY 2026-27 target: ~25 National Highway fee plazas to be converted to MLFF [3]
• Current operational MLFF plazas: Chorayasi (Gujarat), Mundka Bakkarwala (Delhi), Daulatpura (Rajasthan), Manoharpura (Rajasthan) [4]

Highway

• NH-48: Delhi–Mumbai Expressway corridor; Delhi-Jaipur section is among India's busiest inter-state highway stretches.

5. Multi-Dimensional Analysis

Economic

• Eliminates idle-time fuel burn at toll plazas → direct savings for truckers and commuters; reduces logistics costs. [1]
• Reduced infrastructure cost: No boom-barrier hardware, fewer toll booth staff, lower maintenance overheads for NHAI. [1]
• Faster vehicle turnaround improves effective road capacity without adding lane-km.

Technological / Scientific

• Core stack: ANPR cameras + RFID (FASTag) in current MLFF; future convergence with GNSS-based distance-based charging. [5]
• GNSS model (planned): Vehicles fitted with On-Board Units (OBUs) charged proportionally to NH distance — moves away from fixed-plaza model entirely. [5][6]
• System uses real-time number-plate cross-matching with vehicle registration database (Parivahan) to identify defaulters and issue E-Notices automatically.

Environmental

• Zero idling at toll plazas → reduced vehicular emissions (CO₂, NOx, PM₂.₅) at toll locations. [1]
• Supports India's commitments under NDC (Nationally Determined Contributions) to reduce emissions intensity of GDP.
• Improved fuel efficiency at fleet scale has measurable aggregate impact on transport-sector carbon footprint.

Governance / Administrative

• Enhances transparency: Digital audit trail for every transaction; reduces scope for manual fee leakage. [1]
• E-Notice + penalty framework is a shift from physical enforcement to digital compliance enforcement.
• Phased rollout (pilot → corridor → network) follows test-before-scale governance approach.
• Federalism angle: NH management is a Union subject (Entry 23, Union List); States facilitate but NHAI executes.

Legal / Constitutional

• National Highways are a Union List subject (Entry 23); NHAI operates under the NHAI Act, 1988.
• Fee collection authority: National Highways Fee (Determination of Rates and Collection) Rules, 2008.
• Double-penalty for non-payment has statutory backing under fee rules; E-Notice is the procedural mechanism.

10. Common Errors / Trap Areas

1. MLFF ≠ GNSS tolling: Current MLFF uses ANPR + FASTag (RFID). GNSS-based ETC is a separate, future initiative for distance-based charging — often confused in MCQs. [5]
2. Wrong "first" location: India's first MLFF was in Gujarat (Chorayasi, NH-48) on 2 May 2026 — NOT Rajasthan or Delhi. Daulatpura was Rajasthan's first, not India's. [2][4]
3. Wrong highway number: NH-48 was previously numbered NH-8 before renumbering; some older sources cite NH-8 for the Delhi-Jaipur-Mumbai corridor — both refer to the same highway.
4. Ministry confusion: MLFF is under MoRTH (Ministry of Road Transport & Highways), not Ministry of Electronics & IT (MeitY), despite its digital nature.
5. Penalty timeline: Non-FASTag users face double toll at barrier-equipped plazas; under MLFF, double toll applies only after the 72-hour E-Notice window lapses — a procedural distinction exams may probe.
