Intersection Lay-out, Priority Rules and Traffic Safety

This paper reports on the accident-research carried out as part of a large project on priority-rules at intersection, started in 1983. For this accident-research an inventory was made of a large number of intersections. Recorded were lay-out features, accident data and traffic volumes. On a subset of these intersections detailed traffic counts were made. This paper deals with the preparations for this activity, the analysis and the results. The initial conclusions will be presented.
