Operational Mechanisms of a GPS-Based Toll Collection System
Real-time Vehicle Tracking:
Using GNSS technology, vehicles are tracked in real-time as they pass through tolling points. GNSS receivers installed in vehicles communicate with satellites to precisely determine the vehicle’s location at any given moment. This enables transportation agencies to monitor traffic flow and track vehicle movements along tolled roads without the need for physical toll booths.
Automated Toll Calculation:
Toll charges are automatically calculated based on the distance traveled by vehicles on tolled roads. The GNSS technology enables accurate measurement of the distance covered, allowing toll agencies to apply the appropriate toll rates according to the specific sections of the road network traversed by each vehicle. This automated toll calculation process eliminates the need for manual intervention and ensures fairness and accuracy in toll collection.
Instant Digital Payment:
Upon exiting the tolled road or highway, vehicles are automatically billed for the toll charges incurred during their journey. The toll charges are deducted digitally from the linked payment account or prepaid balance associated with the vehicle’s GPS-based toll collection system. This seamless and instantaneous payment process enhances convenience for motorists and reduces congestion at tolling points, as there is no need to stop or wait in line to make toll payments.
Automatic Number Plate Reader (ANPR)
The integration of Automatic Number Plate Readers with GPS-based toll collection enhances accuracy in identifying vehicles. ANPR technology captures and reads vehicle license plates, ensuring precise toll calculations and reducing the chances of errors.
FASTags rely on Radio Frequency Identification (RFID) technology, where passive tags on vehicles are used to make toll payments directly from linked accounts. On the other hand, Automatic Number Plate Recognition (ANPR) technology utilizes cameras to capture images of license plates, enabling automated vehicle identification for toll collection purposes. While both technologies offer automated toll collection capabilities, ANPR technology may provide additional flexibility and compatibility with existing tolling infrastructure.
