Why are roundabouts being utilized more at intersections?

A roundabout is typically the optimum solution for any intersection (up to 50,000 vehicles per day). Engineered to maximize safety and reduce traffic congestion, roundabouts reduce fatal and injury crashes, ease traffic congestion, and reduce energy costs. Since 2008, the Federal Highway Administration encourages public agencies, such as cities, counties, and state highway departments to use roundabouts.
