This report is part of the project 'Accident patterns and accident rates per road type'. This project focuses on the relation between the various road types in the Netherlands and certain accident and rate patterns. With an accident pattern we mean the distribution of accidents among various accident types (crash opponents, manoeuvres). This study examined whether differences in the safety of road types can be explained by differences in combinations of road features. A distinction was constantly made between a traffic engineering approach and a traffic psychological approach. From both lines of approach, hypotheses have been formulated about the relations between road surroundings and/or road behaviour and accidents. With these hypotheses, the traffic engineering and the traffic psychological approaches then appraised the safety of different road stretches. The hypotheses were then tested by comparing the conclusions of the road appraisals based on the hypotheses, with an objective measurement for road safety: the number of accidents. This
