-- Bellevue, WA

"At first, I was a little apprehensive-wondering how they would work to slow traffic ... Overall, I'm very pleased with the way they've slowed traffic down. Traffic in general is traveling at a much slower rate in front of our school than it was prior to the roundabouts."

Quotes from Government or Other Agencies:

"Roundabouts reduce serious traffic accidents, and they eliminate the cost of signal equipment and electric energy costs to run them"
-- Hennepin County Board Chair Randy Johnson

 

"Where roundabouts have been installed, motor vehicle crashes have declined by 40 percent, and those involving injuries have been reduced by 80 percent. Crash reductions are accompanied by significant improvements in traffic flow, thus reducing vehicle delays, fuel consumption, and air pollution."
-- Insurance Institute for Highway Safety

[The roundabouts planned in Richfield] are expected to eliminate serious and life-threatening accidents.  Since vehicles approach roundabouts more slowly and crosswalks are placed slightly away from the circle, pedestrian safety is improved.
-- Richfield Mayor Martin Kirsch
