State-Of-The-Art in U.S. Roundabout Practice

Roundabout practice in the United States has evolved considerably over the past fifteen years since the first modern roundabout was built in the United States in 1990. Professionals guiding the early years leaned heavily on experience gained in other countries, principally Australia and the United Kingdom. In the late 1990s, FHWA guided the development of its document, Roundabouts: An Informational Guide. This document was more than merely a synthesis of existing international documents; it introduced new concepts and began to define an American roundabout practice. Since its publication, a wide variety of activities have influenced roundabout design in the United States, including the construction and evaluation of many roundabouts across the United States, the active development of supplemental guidance materials by several States, increased awareness and research on the accessibility of roundabouts to pedestrians with vision disabilities, and so on. This paper presents the author’s view on the current state of practice in the United States, including a vision of where things may be heading in the coming years.
