Why Roundabouts? Yes. They’re worth the dizziness! Studies show that roundabouts are safer and more efficient than stop sign or signal-controlled intersections Reduction in fatal collisions! Reduction in Collisions Graph shows reductions in collisions when traditional intersection controls are replaced by a roundabout Source: WSDOT Roundabout Benefits Why else do we love them? Reduces Delay Roundabouts reduce delays by as much as 89%. Total vehicle stops are reduced by 56%. Lower Cost Although initial construction costs may be comparable, the long-term maintenance and operation costs of a roundabout are significantly cheaper. Smaller Footprint Although the footprint of a roundabout may be larger than a typical intersection, the total area needed for the approaches to the intersection are reduced because traffic moves through the intersection more smoothly. Where Should They Be Located? High crash rate locations Intersections with traffic delays Complex intersection geometry Frequent left-turn movements www.mackaysposito.com Sources: Washington State Department of Transportation US Department of Transportation
