Iowa goes roundabout
In recent years, roundabouts have been used in the United States to reduce crashes, traffic delays, fuel consumption, air pollution, and construction and maintenance costs.
Roundabouts often move more traffic and enhance intersection beauty. They have also been used to control speed in residential neighborhoods and are accepted as one of the safest types of intersection designs.
The Iowa Department of Transportation and other communities in Iowa have started using roundabouts in certain situations to enhance safety and reduce delays encountered by the motoring public.
Roundabouts have been used effectively throughout the world for many years.
