I was surfing on the City of Carmel, Indiana, website and came across this page explaining the safety and environmental benefits of roundabouts. For those unfamiliar with roundabouts, it's a nice little primer that includes both a presentation and an animation on "How to Negotiate a Roundabout" (sourced from the City of Clive).As an Indianapolis native, I've frequently encountered the roundabouts in Carmel (they currently have over 40 with dozens more planned) and I've got to say they work really well! Traffic flows much better through these European-style intersections than more traditional stop signs and traffic signals.
They've worked so well that Carmel is converting an expressway with signalized intersections into a sunken expressway with roundabout interchanges for exiting/cross-street traffic, with construction starting this year and continuing throughout the next few construction seasons. Project site is located here.
Anybody else have experiences with roundabouts? Any places you think Los Angeles could use some more (PCH has one in Long Beach)?
