Why is it in the News?

Road Transport and Highways Minister Nitin Gadkari said in Parliament in February that the government plans to implement a new highway toll collection system based on the global navigation satellite system before the model code of conduct for the 2024 election kicks in.

What is the Global Navigation Satellite System (GNSS)?

• GNSS refers to a constellation of satellites providing signals from space that transmit positioning and timing data to GNSS receivers.
  • The receivers then use this data to determine location.
• Examples of GNSS include Europe’s Galileo, the USA’s GPS, Russia’s GLONASS and China’s BeiDou

How will the GNSS-Based Toll System work?

• The system will use an automatic number plate recognition (ANPR) system through cameras installed on highways and deduct tolls based on the distance traveled by a vehicle.
• The device monitors the movements while driving, accurately marking the entry and exit points on tolled segments. By analyzing travel distance, it computes the charges accordingly.
• This eliminates the uniformity of fixed tolls at booths, ensuring fairness for drivers traversing shorter distances.

Difference between FASTags and ANPR technology:

• FASTags streamline electronic toll payments at toll plazas equipped with scanners, enabling vehicles to pass through without stopping.
• Conversely, GNSS-based systems utilize ANPR technology to deduct tolls based on distance traveled, rendering traditional toll plazas unnecessary.

What are the Challenges?

• Detection of Non-Compliance: Without physical barriers, detecting non-compliant vehicles, such as those without an On-Board Unit (OBU) or engaging in fraudulent activities, poses a challenge.
• Infrastructure Requirements: Deploying gantry-mounted Automatic Number-Plate Recognition (ANPR) systems along highways is essential for capturing violations and enforcing toll payments.
• License Plate Quality: The effectiveness of ANPR systems relies on the quality of license plates; subpar plates hinder accurate recognition and enforcement efforts.
• Data Privacy and Security: GNSS-based toll systems entail collecting and processing sensitive location data, necessitating robust privacy and security measures.
