Abstract
The topic of this paper is the evaluation of the Stimulation Plan "Actie -25%" for municipalities in The Netherlands. The SWOV Institute for Road Safety Research was assigned to conduct the evaluation study. Two central questions were at issue: (1) Did "Actie -25%, for instance, did the extra (municipal) activities resulting from "Actie -25%", lead to fewer road accident casualties?; and (2) in which ways did the organisation of "Actie -25%" lead to extra (municipal) activities? Can one expect changes in organisation and implementation to lead to increased or better participation of municipalities?
