Recent French Studies on Capacity and Waiting Times at Rural Unsignalized Intersections

Several studies have been undertaken in France during these last years in the field of capacity and delays at unsignalized intersections, in order to provide the engineer with some aids to design. This research, starting from an extensive comparison of the possible approaches, has led to the development of a microscopic simulation program (OCTAVE). Besides, a capacity formula for rural roundabout entries has been derived from measurements. This paper summarizes the main results of these studies.
