The design and use of bicycle facilities at roundabouts in North America has been largely based on guidance provided in NCHRP Report 672: Roundabouts in the United States, Second Edition. In the past few years, the state-of-the-practice design for bicycle facilities in the United States has been significantly updated, especially for intersection treatments, but the design for bicycle treatments for roundabouts is still lagging. Consequently, practitioners have begun looking towards bicycle facility design guidance in other countries and at other intersection types. This presentation reviews bicycle facility design standards and practice at roundabouts both in North America and abroad, and looks at recent bicycle facility design guidance developed for signalized and stop-controlled intersections, and evaluate their relevance at roundabout intersections. A case study at the Inman Square intersection in Cambridge, Massachusetts will be presented, highlighting an example of how protected intersection treatments can be applied to a roundabout design in a constrained urban environment.
