GNSS-based toll collection in India

Highway infrastructure is undergoing a significant transformation with the introduction of GNSS-based toll collection in India. This revolutionary approach promises to eliminate congestion at toll plazas, reduce fuel consumption, and create a more equitable “pay as you use” model for highway users. As the Ministry of Road Transport and Highways moves forward with implementation plans, understanding this technology and its implications becomes crucial for vehicle owners and logistics companies.

India’s Current Toll Collection System and Its Challenges

India’s national highway network spans approximately 1.4 lakh kilometers, with toll collection operational on about 45,000 kilometers. The current toll collection infrastructure relies primarily on FASTag, an electronic toll collection system that uses radio frequency identification (RFID) technology. While FASTag represented a significant improvement over manual toll collection, the system still faces several limitations.

Despite the widespread adoption of FASTag, several challenges persist in the current toll collection system:

• Physical toll plazas create bottlenecks, leading to traffic congestion even with electronic payments
• Fixed toll rates regardless of actual distance traveled on the highway
• Manual exemption processes for local residents living within 20 km of toll plazas
• Infrastructure and maintenance costs for physical toll plazas
• Limited scalability to accommodate increasing traffic volumes

These challenges have prompted the government to explore more advanced solutions that can provide seamless travel experiences while ensuring fair toll collection based on actual usage.

Understanding GNSS Technology and Its Transportation Applications

Global Navigation Satellite System (GNSS) refers to a constellation of satellites that provide geospatial positioning with global coverage. This technology enables users with a compatible receiver to determine their location, velocity, and time by processing signals from satellites in orbit around Earth.

Key GNSS Systems Relevant to India

NAVIC (Navigation with Indian Constellation): India’s indigenous satellite navigation system developed by ISRO, providing positioning services primarily for the Indian subcontinent. The government has confirmed that NavIC will be utilized for the new toll collection system.

GPS (Global Positioning System): Operated by the United States, GPS is the most widely used GNSS system globally and serves as a complementary system for positioning services in India.

GNSS Applications in Transportation

GNSS technology has already transformed various aspects of transportation globally:

• Fleet management and vehicle tracking for logistics companies
• Navigation systems for personal and commercial vehicles
• Traffic management and congestion monitoring
• Emergency response vehicle routing
• Distance-based road pricing and toll collection

The application of GNSS for toll collection represents a natural evolution of this technology, allowing for more precise, fair, and efficient charging based on actual road usage.

How GNSS-based Toll Collection Works in India

The GNSS-based toll collection system in India represents a paradigm shift from fixed toll points to dynamic, distance-based charging. This system utilizes satellite technology coupled with on-board units (OBUs) installed in vehicles to track movement and calculate toll fees based on actual distance traveled.

On-Board Units

Non-transferable GNSS-OBU devices installed in vehicles that communicate with satellites to track movement and distance traveled on highways.

Virtual Gantries

Digital checkpoints that replace physical toll plazas, marking entry and exit points on highways for toll calculation purposes.

Centralized Toll Charger

Backend software that receives data from OBUs, calculates toll fees based on distance traveled, and processes payments through linked accounts.

The Toll Collection Process

1. The GNSS-OBU in the vehicle continuously communicates with satellites to determine precise location.
2. When a vehicle enters a tolled highway section (marked by virtual gantries), the system registers the entry point.
3. As the vehicle travels, the OBU tracks the exact distance covered on the tolled section.
4. Upon exiting the tolled section, the system calculates the fee based on distance traveled and vehicle category.
5. The toll amount is automatically deducted from the user’s linked account (initially using the existing FASTag ecosystem).
6. Users receive SMS notifications confirming toll deductions and journey details.

Key Features of India’s GNSS Toll System

• Pay-as-You-Use Model: Users pay only for the actual distance traveled on highways, ensuring fair pricing.
• 20 KM Free Travel: Automatic exemption for travel up to 20 kilometers in each direction, once per day.
• Hybrid Implementation: Initial rollout will feature dedicated GNSS lanes at existing toll plazas, gradually transitioning to a fully virtual system.
• Phased Deployment: Starting with commercial vehicles (trucks and buses) by June 2025, expanding to all vehicle categories by 2026-27.

Benefits of GNSS-based Toll Collection in India

The transition to GNSS-based toll collection offers numerous advantages for highway users, infrastructure operators, and the environment. These benefits extend beyond mere convenience to create substantial economic and ecological value.
