abstract="New and improved versions of the old fashioned traffic circle are gaining acceptance among traffic planners looking for newer, less costly and safer ways to handle increasing traffic. Now called a &quot;roundabout&quot;, this low-cost, high-capacity concept has been popular in Europe for decades but is only recently gaining acceptance in the U.S. Several elements define a modern roundabout including: flared and tapered add lanes; deflected entry lanes; yield-at-entry traffic regulations; and good visibility. All of these aspects tend to keep speeds down, avoid tie-ups, and increase efficiency of the intersection. One success story involving roundabouts is Vail, Colorado, where nine roundabouts are now in service in a space of nine miles.<p />",
