摘要: This report reviews current research and practice on modern roundabouts, both in the United States and other countries. The report compares the advantages and disadvantages of roundabouts, summarizes safety implications, and discusses pedestrian and bicyclist considerations. Guidance from other states on the geometric design of roundabouts is reviewed, as are studies and formulas used to evaluate roundabout performance, measuring capacity and delay. Software models for roundabouts are reviewed. The report makes recommendations for considering and using roundabouts in Oregon, as well as identifying further research needs in this area.
