📌 Summary:
- NHAI has begun rollout of the Multi-Lane Free Flow (MLFF) Tolling System at Gharaunda Toll Plaza on the Panipat–Jalandhar section of NH-44
- MLFF enables toll collection without vehicles stopping or slowing, using Electronic Toll Collection (ETC) with high-performance sensors and cameras on overhead gantries that auto-identify vehicles and deduct fees via FASTag
- Benefits: zero waiting time, reduced congestion, and savings in fuel and travel time by removing repeated braking and idling at plazas
- Key features: gantry-based collection (5.5–6.0 m vertical clearance); decongested tolling zones with no parking/encroachment within 200 m on either side; enforcement via Route Patrol Vehicles (RPVs)
- Marks a shift from conventional barrier-based toll plazas toward seamless, technology-driven highway travel
🎯 UPSC Relevance: GS3 Economy (Infrastructure) — technology-led road infrastructure reform improving logistics efficiency and ease of mobility.
