Toolbox to Evaluate the Impacts of Roundabouts on a Corridor or Roadway Network

This toolbox provides information to assist transportation agencies in utilizing roundabouts while evaluating traffic control at adjacent intersections, thereby avoiding adverse impacts on corridor performance. The information was developed by summarizing available information and conducting several evaluations. The toolbox addresses roundabouts as they relate to and/or impact the areas of comprehensive planning, mobility, unbalanced traffic flows, access management and other planning considerations.
