NHAI Invites Expressions of Interest for GNSS-based Toll Collection

Context

NHAI has invited expressions of interest (EoIs) from around the world for the implementation of GNSS-based (satellite-based) electronic toll collection to provide a seamless and barrier-free tolling experience for National Highways users.

About GNSS-based Electronic Toll Collection (ETC) System:

• The GNSS-based Electronic Toll Collection (ETC) system is a barrier-free electronic toll collection method that leverages Global Navigation Satellite System (GNSS) technology to monitor vehicles and compute tolls based on the distance traveled on tolled highways.

Working Mechanism:

• Satellite Tracking:
  • The system uses satellites or satellite constellations to track vehicle movements and calculate tolls according to the distance covered on tolled highways.
• OBU Technology:
  • Vehicles equipped with GNSS-enabled On-Board Units (OBUs) are charged based on the distance they travel on tolled stretches.

Implementation Plans:

• The National Highways Authority of India (NHAI) aims to integrate the GNSS-based ETC system with the existing FASTag ecosystem. Initially, a hybrid model will be used where both RFID-based ETC and GNSS-based ETC will function simultaneously.

Significance

• Efficiency:
  • Facilitates smooth vehicle movement on National Highways by eliminating physical barriers at toll booths.
• User Experience:
  • Offers a barrier-less, free-flow tolling experience, making travel hassle-free.
• Cost-Effective:
  • Implements distance-based tolling, ensuring users are charged only for the distance they travel.
• Enhanced Collection:
  • Improves toll collection efficiency by minimizing leakages and reducing toll evasion.
