Implementing Multi-Lane Roundabouts in Urban Areas

An explosion of multi-lane roundabout projects has recently occurred in central Ohio. This paper discusses four transportation improvement studies for which multiple multi-lane roundabouts were chosen as the preferred solution. The projects include: 1) a high volume partial cloverleaf interchange design that will include high-capacity roundabouts at the ramp terminal intersections and other intersections within the corridor; 2) a six-mile extension of a suburban/rural four-lane principal arterial that will include six roundabouts along its length; 3) two closely spaced, high capacity, roundabouts in a densely developed area, near two schools; 4) roundabouts utilized for access improvements in a future office/commercial growth corridor. This paper includes a description of these projects and a discussion of how the choice of mult-lane roundabouts in transportation planning decisions at these locations will reduce delay and vehicle emissions and air pollution while also improving safety, aesthetics, and access management. The analysis presented in this paper is highly abbreviated. Please contact the author for additional information of the analysis.
