There are still few research results on the influence of infrastructural measures on the occurrence of traffic accidents. In particular this applies to the many discussions concerning the woonerf. By means of a before and after study 56 woonerven and 13 other infrastructural measures in redesigned and reconstructed residential areas were studied. The main conclusion from this accident study is that analyses show a big reduction in the number of accidents when such measures were taken. The reduction was the greatest in woonerven but other experimental measures show also a positive effect on traffic safety. The execution of the measures should be as intensive as possible, with the aid of obstacles, road humps, modifications in the longitudinal profile, while the footpaths should be maintained as well as possible. The greatest decrease is in the number of accidents to pedestrians and moped riders.
