Title: A Behavioral Lane Changing Model for Roundabout Design
Abstract: In recent years, intersections planned with roundabouts have had a remarkable diffusion, especially in urban areas. Compared to conventional intersections, this system is suitable to improve road safety. In Italy, in spite of many positive experiences that have been made, still there is no defined norm and regulation for roundabouts. This research can give guidelines for norms and roundabout design, through the development of a generalized behavioral model. In particular, the proposed model simulates user’s lane changing choices inside the roundabout. In this paper, a behavioral Nested Logit model is proposed. Preliminary results, obtained through application on some urban roundabouts, showed that roundabouts perform depending not only on the flow in the weaving area and the length of the weaving area, but also on the speed of vehicles changing lanes and critical gaps.
