This paper analyses several aspects of the Dutch experience of speed enforcement, and presents the results of some speed management experiments in The Netherlands, using automatic warning of speeders and enforcement of speeding. Traditional approaches to manage speed there have not resulted in satisfactory speed behaviour by drivers, so that new and more efficient methods for handling the speed problem are being sought. The new approach, now being tested, is based on the advantages of reduced car speeds and of high objective and subjective detection rates through efficient and effective automatic warning and enforcement. A local speed warning system was tested at an urban intersection in The Hague and a rural intersection in Friesland. Four experiments were conducted on two-lane rural roads with an 80 kph speed limit. There were two types of speed measurements, aiming to reduce: (1) high and low speeds on two roads closed to slow vehicles; and (2) high speeds on two roads also open to tractors. A speed enforcement project in Friesland was recently started on 38 stretches of rural roads, with a speed limit of 80 kph, with great potential for accident reduction.
