Drachten received international attention for a traffic experiment known as shared space, a concept pioneered by Hans Monderman. Almost all traffic lights and signs have been removed in the town's centre in an effort to improve traffic safety, based on the theory that drivers pay more attention to their surroundings when they cannot rely on strict traffic rules. Previously the town's centre had an average of 8 accidents per year. In the first two years after the system was introduced, yearly accidents were reduced to 1.
