Abstract

Several studies have suggested that the entry capacity of roundabouts depends on the critical
gap. Accordingly, the assumption in calculating the capacity is that all drivers are homogeneous and consistent; i.e., their behavior does not change over time. This paper examines the accuracy of this assumption; in particular, it evaluates the effect of waiting times on drivers’ critical gaps.
