Free Flow Tolling and Security Monitoring on Highways with ANPR

Free Flow Tolling and Security Monitoring on Highways with ANPR

In the world of tolling, two major categories exist: free-flow tolling and stop-and-go tolling. The difference between those two is of course obvious. ANPR is often used for stop-and-go tolling where the driver has to slow down the car and get a ticket of pay for using the road at a toll booth. In those cases many ANR cameras will be capable to read the license plate: The car is perfectly positioned and has stopped moving. Perfect conditions to have the ANPR camera perform its OCR task.

Wikipedia perfectly explains what free-flow tolling is: Open road tolling (ORT), also called all-electronic tolling, cashless tolling, or free-flow tolling, is the collection of tolls on toll roads without the use of toll booths. Cars can move around on the road freely. This solution allows drivers to travel without experiencing hick-ups or traffic queues resulting from the tolling installation. Cameras and other devices at gantries or bridges are used to monitor the traffic and identify the vehicles passing by. You can imagine that having ANPR cameras perform well under these circumstances is sometimes a challenge.
