It's a multilane roundabout, but the different directions are separated. It can handle more traffic than a standard multilane roundabout. This is the largest one we have now, though most a just two lanes wide: http://maps.google.nl/maps?f=q&source=s_q&hl=nl&geocode=&q=51.968099,4.456133&aq=&sll=51.969019,4.456179&sspn=0.012519,0.033023&ie=UTF8&ll=51.968097,4.456158&spn=0.001565,0.004128&t=k&z=19 I was wondering if people outside the NL are familiar with the turbo roundabout?

While it serves a local population most of the year, in summer it gets traveled quite a fair bit by tourists headed for the beaches. Even then it fares quite well.

They started to build a few in the 90s but only in the last ten years they became really popular. And, I've never seen one without any kind of barrier in the center. There are lots of regulations how to set up roads and signs by authorities (e.g., using the wrong font or type of arrow on a sign makes it invalid) so it's pretty surprising that this is possible. I guess the problem is that the right-of-way rules are completely different if you don't recognize the roundabout as such by the small blue sign (which is essential). In that case the red triangular sign means to let cars from the left and the right pass which also confuses as that street is much smaller. Roundabouts are a pretty new thing in Germany.

A plus of this design is that long trucks with trailers can still pass the intersection.

I can only imagine what would happen if you put one of those in a city in the US, or better yet a city that gets any kind of snowfall...

More importantly, what is the design of the road leading up to this intersection. People seem to be coming up to it at something like 90 kph. It looks like this design would benefit from some traffic calming on the road below this intersection.
