This report documents the findings from an international study on turbo roundabouts undertaken as part of the Federal Highway Administration’s Office of International Program’s Global Benchmarking Program. The study was motivated by the growing domestic interest in and installation of turbo roundabouts to combat the disproportionate number of property damage only (PDO) crashes at some U.S. multi-lane roundabouts. The report summarizes international experiences with turbo roundabouts to provide information on the benefits and challenges of their implementation, to determine the availability and applicability of design guidance, and to identify opportunities for further turbo roundabout implementation in the U.S. The study identified many examples where the visited countries implemented turbo roundabouts with positive results that will inform implementation in the U.S.
