Synthesis of North American Roundabout Practice

TAC has just released the Synthesis of North American Roundabout Practice featuring current practices and experiences with roundabouts. It forms an expanded counterpart to National Cooperative Highway Research Program (NCHRP) Synthesis 264, "Modern Roundabout Practice in the United States", published in 1998. Not to be confused with older traffic circles or rotaries, roundabouts are a more compact, safe and efficient form of intersection control being constructed in Canada in increasing numbers as an alternative to stop control or traffic signals. The TAC synthesis provides a review of literature, research and case studies, and is supplemented with selected international experience. An outline of responses from a web-based survey of public road agencies in Canada and the United States on roundabout planning, design and operating practices is included, and resulting conclusions and best practices are summarized.
