Government budgets are tight. Roads are reaching capacity. Motorists complain of congestion. As these macro trends accelerate, forward-thinking cities are beginning to embrace congestion charging schemes to improve system-wide traffic flow, reduce congestion and minimise pollution while optimising the use of limited road infrastructure in urban areas. By strategically developing a "zone" of Automatic Number Plate Recognition (ANPR) cameras around urban centres and charging for entering the zone many governments are preparing their cities for the increased demands of the future.
A congestion fee program involves charging a rate that varies based on the roadway used and the time of day. 3M ANPR technology, when used in a congestion fee charging application, effectively provides accurate and timely information to identify and charge vehicles. 3M ANPR systems may also complement or validate RFID technology, which is frequently used in congestion fee applications.
