Kittelson & Associates, Inc. is a national leader in the planning, design, and operations of roundabouts. Our firm has been involved in the feasibility study, peer review, and/or final design of over 200 potential or constructed roundabouts throughout the United States and Canada.
We provide ongoing on-call services in each of these areas to several state departments of transportation, including Maryland State Highway Administration, Kansas Department of Transportation, and Iowa Department of Transportation. We led the development of FHWA's Roundabouts: An Informational Guide; prepared supplements to that document for the States of Arizona, Kansas, and Maryland; and are currently active in updating the Manual on Uniform Traffic Control Devices and the Highway Capacity Manual.
We have also led the most comprehensive research study of roundabouts in the United States (NCHRP 3-65, Applying Roundabouts in the United States), which gives us a particular sensitivity to how American roundabout users operate roundabouts and how they might use roundabouts differently than what is seen internationally.
