What is GNSS Tolling? GNSS vs FASTag, Advantages, Disadvantages and More

As India prepares to roll out a GNSS-based electronic toll collection (ETC) system, the country is eager to make toll collection on its vast road network more efficient and hassle-free. Harnessing the power of Global Navigation Satellite System (GNSS) technology, this cutting-edge solution enables vehicles with GNSS tags to pass through toll booths without stopping. But how does this satellite-based system differ from the existing FASTag system? Let’s explore the differences.

What are GNSS charges?

GNSS Toll Collection is a satellite-based electronic toll collection system that uses Global Navigation Satellite System technology to track and collect tolls from vehicles. Vehicles equipped with GNSS-enabled tags transmit location and speed data to a central system that calculates tolls based on distance traveled and speed. The technology eliminates physical toll booths, reducing congestion and errors while increasing efficiency and revenue. It provides a seamless, hassle-free travel experience, making it an ideal solution for toll collection agencies around the world.

GNSS-based toll collection system and FASTag system

Satellite toll collection uses GNSS technology and will introduce virtual toll booths on roads and highways, monitoring the distance travelled and location of GNSS-enabled vehicles. These virtual toll booths will also capture vehicle details including type, license plate number and bank account information. In contrast, FASTags requires physical toll booths to track and collect tolls on vehicles, while GNSS-enabled vehicles will enjoy a seamless, toll booth-free experience.

Advantages of charging for GNSS systems

The implementation of a GNSS-based Electronic Toll Collection (ETC) system aims to significantly reduce waiting times, cutting the average waiting time from 714 seconds to just 47 seconds, thereby improving operational efficiency. This significant reduction will minimize travel times, streamline traffic flow and improve the overall driving experience. Here are some of the benefits of GNSS-based tolling:

  • Real-time tracking: GNSS enables real-time vehicle tracking, enabling efficient toll collection and monitoring.
  • Reduced infrastructure costs: GNSS-based toll collection eliminates the need for extensive physical infrastructure such as toll booths and gantries.
  • Improved convenience: GNSS charging enables seamless, hassle-free travel, reducing congestion and waiting times.
  • Improved traffic flow: By reducing the need for physical tolling infrastructure, GNSS tolling can improve traffic flow and reduce congestion.
  • Enhanced User Experience: GNSS toll collection provides drivers with a convenient, hassle-free experience, without the need to stop or interact with toll collection devices.
  • Increased revenue: GNSS charging can help reduce toll evasion and increase revenue for toll collection agencies.
  • Scalability: GNSS charging can be easily scaled to accommodate growing traffic volumes and expanding road networks.
  • Interoperability: GNSS is a standardized technology that enables interoperability between different toll systems and regions.
  • Data analytics: GNSS charging provides valuable data insights into traffic patterns, helping authorities optimize traffic management and planning.
  • Environmental benefits: By reducing the need for physical infrastructure and minimizing congestion, GNSS charging can help reduce environmental impact.
  • Cost-effective: GNSS charging is a cost-effective solution for toll collection agencies, reducing operating and maintenance costs.

By adopting this forward-looking approach, traffic congestion will be significantly alleviated, and a smooth and continuous flow of vehicles will be achieved without the need to add toll lanes. In addition, the elimination of physical toll booths will simplify the billing process, allowing users to pay only according to the distance traveled, thereby reducing toll booth maintenance and construction expenses, thereby saving costs.

Disadvantages: GNSS system charges

Although GNSS-based systems are a significant improvement over the existing FASTag system, some challenges remain, especially in areas with poor signal reception, such as in rural areas or rugged terrain. Here are some of the disadvantages of GNSS (Global Navigation Satellite System) when it comes to charging:

  • Signal multipath: GNSS signals can be affected by multipath interference, resulting in inaccurate position data.
  • Satellite geometry: Poor satellite geometry can lead to reduced accuracy and reliability.
  • Atmospheric interference: Ionospheric and tropospheric delays affect GNSS signal accuracy.
  • Limited coverage: GNSS signals may be weak or unavailable in urban canyons, tunnels, or dense tree cover.
  • Dependence on satellite signals: GNSS charges rely on satellite signals, which can be easily interfered with or disrupted.
  • High initial investment: Implementing GNSS charging requires significant upfront investment in infrastructure and technology.
  • Privacy issues: GNSS tracking raises privacy concerns as it can be used to monitor vehicle movements.
  • Technical complexity: GNSS toll collection systems require complex technology and expertise to install and maintain.
  • Potential for signal jamming: GNSS signals may be intentionally jammed, disrupting toll collection services.
  • Compatibility issues: Different GNSS systems (e.g. GPS, GLONASS, Galileo) may have compatibility issues, thus affecting interoperability.

To ensure a seamless transition to this cutting-edge charging technology, it is critical to address these technical hurdles and user privacy concerns, paving the way for a successful implementation in India.
