Source-This post on GNSS-based Electronic Toll Collection (ETC) System has been created based on the article “NHAI Invites Global Expression of Interest for Implementation of GNSS-Based Electronic Toll Collection in India” published in “PIB” on 7 June 2024.

Why in News?

The Indian Highways Management Company Limited (IHMCL), promoted by the National Highways Authority of India (NHAI), has issued a global call for Expressions of Interest (EOI) to develop and implement a GNSS-based Electronic Toll Collection (ETC) system on India’s National Highways.

About GNSS-based Electronic Toll Collection (ETC) System

1.  The GNSS-based ETC system utilizes Global Navigation Satellite System technology to facilitate electronic toll collection without physical toll barriers.

2.  By using satellites or satellite constellations, the system accurately tracks vehicle movements and calculates tolls based on the distance traveled on tolled highways.

 Key Features of the System

1. Vehicles must be equipped with GNSS-enabled On Board Units (OBUs) to be part of this toll collection system.

2. The NHAI plans to integrate this system within the existing FASTag ecosystem, starting with a hybrid model that supports both RFID-based and GNSS-based ETC simultaneously.

Significance of the GNSS-based ETC System

1. The system is designed to ensure smooth vehicle movement along National Highways by eliminating physical toll booths.

2. It offers a barrier-free tolling experience, significantly reducing congestion and wait times.

3. It implements distance-based tolling, where users are charged solely for the segments of the highway they use.

4.  it aims to enhance toll collection efficiency by minimizing revenue leakages and preventing toll evasion.

About Global Navigation Satellite System (GNSS)

1. About: The Global Navigation Satellite System (GNSS) is a constellation of satellites orbiting Earth, continuously transmitting radio signals with precise time and orbital information.

2. Components of GNSS: It consists of satellite and a receiver.

i) Satellites: Orbit the Earth, transmitting time-stamped signals.

ii) Ground Control Stations: Monitor and manage the satellite constellation.

iii) Receivers: Devices that capture satellite signals to determine precise location.

3. Applications of GNSS

i) Navigation: Used in aviation, maritime, and road transport.

ii) Mapping and Surveying: Provides precise geospatial data for mapping and land surveys.

iii) Agriculture: Enables precision farming techniques.

iv) Disaster Management: Assists in emergency response and disaster relief operations.

v) Telecommunications: Synchronizes networks and systems.
