The Evolution of Roundabout Planning & Design

Roundabouts continue to be a popular intersection choice for many agencies in the U.S. Much experience has been gained in the past decade regarding the design and performance of roundabouts in the U.S.

This presentation will give transportation engineers and planners a solid overview of current analysis and design practices related to roundabouts based on the presenters’ experience and involvement as a member of the Transportation Research Board’s Roundabout Committee. Topics to be discussed: 

  • Go-to U.S. planning and design guidance and resources
  • Recent and ongoing research that will influence roundabout policy and practices
  • Current and draft federal ADA rules for pedestrian crossings
  • Common crash patterns at multi-lane roundabouts 
  • Roundabout capacity analysis options and the strengths and weaknesses of each
  • Important considerations when conducting studies that compare the potential benefits, impacts, and costs of roundabouts to other intersection options
  • Roundabout myths and misunderstandings
  • Some entertaining quotes from social media and public surveys related to roundabouts
