Abstract

The increasing use of roundabouts for plane junctions calls for an evaluation of the potential accident rate for this kind of intersection. This gives a further element for the choice between alternative typologies of intersection for the requalification and the adjustment of road junctions. This paper presents a model for the potential accident rate evaluation in large and medium roundabouts. The model is based on dynamical considerations and on the user’s behavior crossing the intersection. The model’s response to the traffic conditions in the intersection and to capacity formulations is also analyzed.
