Abstract

Deel I Accident rates and type and with of median. Operating conditions as measured by the average daily traffic volume apparently influence the relative safety of the deterring and non-traversable medians. In the volume range between 15.000 and 130.000 vehicles per day, the deterring type median had the lower accident and injury rate. While the non-traversable median had fewer approach type accidents, the higher rates of overtaking and single vehicle accidents more than offset this advantage. In the volume range of 130.000 vehicles or more per day, the advantage shifted the non-traversable median, which had the lower accident and injury rate. Deel 11 Fatal accidents, full freeways and median barriers geeft een ongevallen analyse van ongevallen naar wijze van deelneming, middenbermongevallen en inhaalongevallen. Geeft een overzicht van ervaringen met verschillende soorten middenberm.
