Samenvatting
An account is given of speed management experiments carried out in The Netherlands on four 2-lane rural roads with a speed limit of 80 km/h. The experiment involved an information campaign, warning signs and a radar camera system. Fixed signs advised a speed of between 60 and 80 km/h and an automatic sign was activated when drivers exceeded 80 km/h. Preliminary results of the experiment are given including speed measurements and accident rates.
