As professor of Transport Policy, Bert van Wee has written an article in the ‘Algemeen Dagblad’ (Dutch national paper) about the efficiency of scan cars and why they will only be used more and more in the future. He explains that the average number of scans per hour – of a scan car – is approximately 2,000, while an on-street enforcer manually scans approximately 70. In addition to that, the number of parking fines has tripled in some municipalities, which increases income for the municipality.
Many Dutch municipalities are described in the article, including municipalities which use the Brickyard scan cars as a solution.
