A speed campaign in the South East of the province of Friesland

SWOV has carried out an evaluation study (R-98-46) of which the objective was to ascertain the effect of a long and repetitive campaign on speeding, offences and attitude of drivers on a network of rural roads with a speed limit of 80 km/h. A campaign was conducted in South East Friesland, part of a northern province in the Netherlands, during a period of 2.5 years.

The aim of the campaign was general prevention, that is to reduce speeds driven, irrespective of time and place. The campaign consisted of: publicity, enforcement using a radar car and camera (speeders were not stopped), a feed-back sign downstream the radar car ("Your speed has been checked"), and a survey among drivers.

The main results were that although the percentage of speeders on two intensely controlled roads was reduced, the percentage of speeders was still high: 68% on one road and 41% on the other. There was almost no spreading effect on the neighbouring ioads.
