Many drivers are apprehensive to accept a roundabout as a viable form of intersection, but their
safety and mobility benefits are increasing their popularity among designers. This thesis is an indepth study of a specific approach at a roundabout in Bangor, Maine. The location was
previously two separate “T” intersections, one of which was a high crash location. The reduction
in reported crashes at this location after installation of the roundabout warrants a performance
evaluation that not only looks at all the drivers using the intersection as a whole, but also focuses
on different groups of users to determine, if there is a problem, where it may lie within the
