“Just imagine a post-Sandy, post-Katrina or post-Andrew world where recovery funds were put to work building resilient, sustainable modern roundabouts instead of rebuilding fragile, polluting signalized intersections,” Mr. Sides, the visitors engineer, mentioned.

The United States has been gradual to undertake fashionable roundabouts, although that’s altering considerably. By one rely, they now quantity about 7,900 countrywide, with a whole bunch added every year. Still, hesitation stays.

Mr. McBride, who, as Carmel’s metropolis engineer for 13 years, oversaw the development of practically 80 roundabouts, mentioned roundabout-curious municipal leaders usually requested how one can win over the public.

“You can spit out fact-based data, but at the end of the day most of the general population is scared of things that are new and different,” Mr. McBride mentioned.

Roundabouts put choice making in the palms of drivers, in contrast to a lot of the U.S. roadway system, which, Mr. McBride mentioned, “doesn’t put a lot of faith in the driver to make choices.”

“They’re used to being told what to do at every turn,” he mentioned.

More than half of all severe crashes occur at intersections, in line with the Federal Highway Administration, which has been pushing the development of contemporary roundabouts for 20 years and offers funding for them via freeway security, congestion mitigation and air high quality enchancment packages.

In the course of selling roundabouts, Mr. Brainard visited Sarasota, Fla., in 2009, the place he mentioned he was met with a roomful of angry people. Among their fears: roundabouts have been dangerous for pedestrians and would trigger uneven put on on tires. But Mr. Brainard’s spiel about Carmel’s experiences evidently hit residence. Sarasota now has a dozen roundabouts, with one other in development and 5 extra deliberate, and simply this yr received the Innovative Roundabout of Merit Award.
