About the research

This Toolbox to Evaluate the System Impacts of Roundabouts on a Corridor or Roadway Network was developed to assist transportation agencies with assessing the impacts of roundabouts on a corridor or system in terms of transportation planning, corridor and network mobility, land use, flow conditions, access management, and other planning considerations (e.g., pedestrians, emissions). The Toolbox will allow agencies to consider the “big picture” rather than assessing the safety and/or operational impacts of isolated roundabouts.
