Implementing a new GPS-based toll collection system, here’s how

The Indian government has approved a GPS-based toll collection system that allows drivers to pass through toll booths without stopping. The system uses Global Navigation Satellite System (GNSS) technology to track vehicles and automatically calculate tolls. To encourage usage, the government has allowed a grace period of up to 20 km of free travel on national highways. Drivers can travel 20 km in either direction without paying tolls. However, vehicles with national licenses do not have this grace period. After the first 20 km, drivers will be charged per kilometer based on the exact distance traveled. The system covers all national highways, bridges, bypasses and tunnels.

How does the system work?

India is moving to a more efficient toll collection system using GPS technology. Currently, vehicles stop at toll booths to pay, causing traffic jams. The new system will solve this problem by charging vehicles based on the distance they travel.

Vehicles equipped with an on-board unit (OBU) or compatible tracking device will automatically pay tolls. Advanced technologies such as digital image processing and CCTV surveillance will verify the location to accurately calculate the toll. The OBU transmits the vehicle’s location data to satellites. Using GPS and GNSS technology, the system will calculate the distance traveled and determine the toll.

GNSS-based toll collection systems face several challenges. Signal interference caused by multipath reflections can lead to inaccurate location data. Signals can be weak or intermittent in areas such as tunnels and elevated roads. Bad weather can also interfere with satellite signals.

The system will be rolled out first on some highways and expressways. Drivers can purchase and install the in-vehicle device from the government portal, similar to FASTag. In the future, new cars may come pre-installed with the in-vehicle device.

The GPS-based toll collection system aims to reduce traffic congestion, simplify the toll collection process and make driving more convenient.
