Roundabouts, traffic flow and public opinion

Overall, 36 percent of drivers supported the roundabouts before construction compared with 50 percent shortly after construction. Roundabouts had very positive effects on traffic flow. Average intersection delays during peak hours at the three sites were reduced by 83-93 percent. Traffic congestion, as measured by the vehicle-to-capacity ratio, was reduced by 58-84 percent. These results provide further evidence that roundabouts can improve traffic flow and that public support for roundabouts increases after they are in place. (A)
