Optimizing the detection of tollable vehicles on toll roads

摘要

Disclosed is a method for optimizing the detection of vehicles liable to pay tolls on toll roads of a road network. The method includes using a vehicle-mounted position determining unit connected to a vehicle external management unit. Toll roads are overlaid in an electronic image of the road network by detection zones (E), and the position determining unit, upon determining vehicle positions (PE) within the detection zones, determines toll-related data and sends the data to the management unit. Monitoring zones (K) are also provided in the image, and are assigned to and extend beyond their assigned detection zone. The position determining unit, upon determining journeys exclusively within the monitoring zone and outside the detection zone, sends position data (P-K-) of the journeys to the management unit. The management unit then performs a retrospective check of the position data (PK-) to determine whether the detection zone should be adjusted, and adjusts if necessary.
