Give me a museum and I'll fill it. (Picasso) Give me a forum ...
I much prefer traffic circles over standard intersections, but that’s old news.
Our move to NC has introduced us to diverging diamond interchanges for highway interchanges and overpasses. At first it felt strange and [-]unsafe[/-] counterintuitive. But between the traffic flow and traffic lights, they work very well and reduce accidents by about 50%! There are construction and (less) land benefits too.
I am sure some of you have seen these before. Just interesting and new to us. If I was in a community proposing DD’s, I’d support it!

The Diverging Diamond is based on the idea that if you can eliminate the need for left-turn arrows, then signals will have maximum efficiency, fewer conflict points, and be able to serve more traffic with better safety and less congestion.
Mr. Don Saiko, MoDOT Project Manager, reports that in survey's conducted after opening, 97% of respondents believe the projects made the area seem safer, 95% believe it is less congested, and 87% believe it is easier to drive than it was before. Mr. Saiko also notes that crash data collected in the first six months suggest a 50% overall reduction.
Fear that drivers would be confused and make mistakes in moving to the "wrong side of the road" have proven unfounded. Having driven this one in Utah, good channeling and signage make the transition very natural. You can hardly tell that anything unusual is happening. Hooray that DOTs across the country are finally taking this concept seriously!
