FACTS

The public will never accept roundabouts.

 

In many cities, proposals to construct modern roundabouts have been met with a public outcry. Follow up surveys have universally found that most people change their mind after they get used to modern roundabouts.

In Anchorage, the first roundabout at Washington Avenue and Southport Drive, was blasted by some of the public. Many supported the roundabout from the beginning. Go to Southport comments for a full transcription of the public's calls to the Municipality of Anchorage. In fact, while many voiced a dislike of the roundabout, more residents expressed support for them. See the Anchorage Daily News web site for letters with titles like "Just Adjust! Roundabouts are really efficient and kind of fun to drive" or "Is driving in a circle that difficult for Anchorage motorists?" or "Southport Drive roundabout has made for a much safer intersection."

One of the other cities with similar experiences is Seattle. According to the Seattle Times article in June 2002, a demonstration roundabout built in a residential neighborhood at Inglewood Hill Road and 216th Avenue Northeast has also gained public acceptance. The accident reduction in Seattle is not unique. Similar results were recorded in Maryland. The article noted that since the roundabout opened in January 2002 only one accident, involving a drunk driver, has occurred at the intersection. The article also noted that in the prior 16 months, police logged 19 crashes at that intersection.

The following table shows similar accident experience at a roundabout in Maryland extracted from an October 2001 "Maryland Roundabout Safety Experience" summary. The summary covered 8 roundabout locations-all of which experienced reductions in crashes after installation of the roundabout.
