Mini-Roundabout CMF Development


The mini-roundabouts are best suited to environments where speeds are already low and geometric constraints would preclude the use of a larger roundabout with a raised central island. The safety benefits associated with mini-roundabouts are not well documented and must be evaluated for engineers to consider for more mini-roundabout installations. The main objective of this research is to compute crash modification factors (CMFs) for mini-roundabouts based on before and after crash data and cross-sectional design.
