Haalbaarheid kencijfers voor lagere-orde-wegen en langzaam verkeer. Deel 1: een inventarisatie van kosten en baten. In opdracht van Directoraat-Generaal Rijkswaterstaat, Adviesdienst Verkeer en Vervoer AVV.

For some time, the SWOV Institute for Road Safety Research has had at its disposal key risk indexes that describe the safety level on various road types. Since 1996, these figures have been determined by means of KenPro, a calculation program that contains a sample of main roads located both inside and outside urban areas. Since the greatest percentage of accidents involving road casualties occurs on the more important roads, it was decided to focus primarily on these. Data about `lower-order roads' (residential roads, roads in pedestrian precincts and rural roads) is not represented in the key risk indexes. The same applies to data about slow traffic, limited in this study to bicycle traffic. The study lists the costs and benefits involved in order to arrive at a well-considered choice as to whether or not to determine key risk indexes for the underlying road network and slow traffic. Adding the data associated with slow traffic to KenPro's total sample would cost approximately 200,000 to 250,000 Dutch guilders. For gathering the necessary sample of lower-order roads, an amount of approximately 200,000 Dutch guilders is estimated. For the second part see C 11054 (IRRD 491569).
