I could see there being less accidents of the left-turn variety being exchanged for more less-dramatic accidents.
Aren't we better of just using roundabouts? or http://en.wikipedia.org/wiki/Roundabout#Turbo_roundabouts??
I live in a town of spectacularly bad drivers so I may be jaded, but I just can't believe folks will "figure this out". People where I live have a hard enough time figuring out what lane they should be in on a straight two lane road let alone merging, signalling, stopping at intersections, one-lane roundabouts, etc.
You might think so, but everyone says this everywhere in the world. For example, this is the top argument that people use against the implementation of the generally-safer, higher-throughput modern roundabouts. Without fail, every time a modern roundabout is installed, the exact same thing happens: congestion is eased, the incidence of fatal accidents falls some 90%, and a multitude of people say things like "well, I…

Something for everyone: overpass, circle, and jug handles:

Massachusetts has the worst drivers in the the country - that is a fact - MA has the highest accident rate in the US. I blame the roads. Every intersection in MA is unique - there are no idioms.

A high accident rate is not proof that Massachusetts "has the worst drivers in the country". I've lived in Massachusetts (and New Jersey, California, and a bunch of other places that like to call themselves the "worst drivers"), but everywhere I go, it seems apparent to me that road conditions and layout account for the huge majority of deviations from place to place.
For example, in New Jersey there are a ton of highways that don't have onramps (or about 15 feet of it). Because of this, there are a lot more (I mean a LOT more) collisions on the "onramp" and people generally are used to swerving in front of 65-mph traffic from a complete stop.
In California you have just as many people (or maybe more) who swerve in and out of lanes at unreasonable speeds, but since there are so many lanes and since they're all so fantastically wide, that sort of behavior doesn't get punished as it might, say, on the Mass Pike or the Garden State Parkway. At the same time, city roads in California (at least in OC) tend to have much higher speed limits. This causes a marked increase in fatal collisions at these types of intersections...not because the people are inherently more aggressive, but because the roads shape their behavior.

What is it? Bad driver, or bad driving conditions?
I didn't get very much sleep last night, but it seems like a more complicated solution than just using "jug handles".
"New" ?? This was discussed 410 days ago:: http://news.ycombinator.com/item?id=1437430 Also just recently re-submitted: http://news.ycombinator.com/item?id=2833446 In particular, here's the WikiPedia article about the design: http://en.wikipedia.org/wiki/Diverging_diamond_interchange
New to most people; I haven't driven through one yet. And on the timescales of road engineering, pretty much anything novel in the past 20 years that's not yet widespread is still 'new'.
