Moving to Germany and traveling throughout Europe, I noticed (over and over again) the use of traffic circles and/or round-abouts and the minimal usage of STOP signs (the town I live in has ONE, yes only one, stop sign and it was added only a year ago at a blind turn). While the Europeans use lots of YIELD signs, they also use traffic circles/round-abouts at most intersections and they are fabulous, not to mention you RARELY EVER see traffic accidents.
After driving in America once again (at these ridiculously slow speed limits - oh Autobahn, how I miss you so), I have noticed the lack of traffic circles/round-abouts while at the same time, noticing the extreme amount of traffic accidents. Coincidence? I think not. Want proof? Read the article below.
Round-abouts are newsworthy: http://www.annarbor.com/news/data-shows-roundabouts-improve-safety/ - Ann Arbor's addition of roundabouts prove that they work, successfully minimizing traffic accidents and improving safety. Why is America the only country not using round-abouts?!
