    • Abstract:
      Mini-roundabouts are a type of roundabout characterized by a small diameter and traversable islands (central island and splitter islands). Mini-roundabouts offer most of the benefits of regular roundabouts with the added benefit of a smaller footprint. As with roundabouts, mini-roundabouts are a type of intersection rather than merely a traffic calming measure, although they may produce some traffic calming effects. They are best suited to environments where speeds are already low and environmental constraints would preclude the use of a larger roundabout with a raised central island. Mini-roundabouts are common in the United Kingdom (U.K.) and France and are emerging in the United States (including states such as Maryland and Michigan), Germany, and other countries. This technical summary focuses on single-lane mini-roundabouts. Because experience with mini-roundabouts is limited in the United States, the information presented here draws primarily upon guidance and experience from other countries with reference to American guidance as appropriate. This technical summary explores the unique characteristics of mini-roundabouts while reinforcing the need to apply the principles-based approach common to all roundabout design. It provides readers with an overview of the key considerations for planning, analysis, and design of mini-roundabouts.
