GNSS-based Electronic Toll Collection (ETC) system

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

The GNSS-based Electronic Toll Collection (ETC) system is a barrier-free method of electronic toll collection that uses Global Navigation Satellite System (GNSS) technology to track vehicles and calculate tolls based on the distance travelled on tolled highways.
Working: The system uses satellites or constellations of satellites to track vehicles’ movements and calculate tolls based on the distance travelled on tolled highways.
Vehicles equipped with GNSS-enabled On Board Units (OBUs) are charged on the distance they have travelled on tolled highway stretches.
NHAI plans to implement the GNSS-based electronic toll collection (ETC) system within the existing FASTag ecosystem, initially using a hybrid model where both RFID-based ETC and GNSS-based ETC will operate simultaneously.

Significance:

Facilitates smooth vehicle movement on National Highways.
Provides barrier-less, free-flow tolling for a hassle-free experience.
Implements distance-based tolling, charging users only for the distance travelled.

Enhances toll collection efficiency by reducing leakages and curbing toll evasion.

Q1. What is a FASTag?

A FASTag is an electronic toll collection system used in India. It is a rechargeable RFID passive tag that allows drivers to pay tolls electronically without stopping at toll plazas. The tag is affixed to the windscreen of vehicles and uses Radio Frequency Identification (RFID) technology to deduct toll fees from linked bank accounts or prepaid wallets.
