[MissoulaGov] Arthrur 5th roundabout?

[Russ Fletcher]

"Chaos," said Portland traffic engineer Scott Batson, "seems to be 
coming back as a way to control traffic."    Drivers behave more 
responsibly when faced with uncertainty, becoming more aware of others. 
The evidence from Holland shows crashes are now far less serious, mostly 
because open-range roundabouts have taken the place of stop signals and 
signs.   http://matr.net/article-36567.html
