I like this type of motorway exit. I think it is a simple and fast way to get in/out of the motorway.

A similar roundabout in Slovakia, on D1, near Liptovsky Mikulas:

It looks more like 0 than O.

It isn't the same turbo-roundabout that the one in Pijnacker? (Which is also near Rotterdam)

Here's another zero-shaped roundabout in Huesca:

But this potato-shaped roundabout in Girona is really if you want to turn around:

We've got the first roundabout with traffic lights before and in it in Slovenia. It's actually reconstructed Tomačevo roundabout in Ljubljana between the H3 and G104 expressways, which was added another 4-lane entry/exit road for a new stadium. Here's a simulation:

Interesting design. It's basically a traffic light controlled, multi-lane turbo roundabout.

New roundabout in Szeged(Hungary), spiced with tramways...





This video shows how the traffic lights, cateyes are being programmed:

I like that new roundabout in Szeged. I drove through it for the first time on Wednesday and I saw it has LED lights that are on even during day light, not only in the evening. You can also see that roundabout here (at 9:05). If you want I can upload that part of the video at normal speed.

The in road LED's look really nice, but if a road is busy enough need traffic lights IMO you're better off going with a tradtional four way intersection.

Really quick view of the roundabout! But nice trip, thank you for the video!

Another video about the roundabout in the night:

This video shows how the traffic lights, cateyes are being programmed:
Why does this need to be circular when the signal phasing work exactly like a 4-phase split for each approach with protected turning, and the long queues.
This could have been done just like a traditional "+" intersection, with shorter travel distance.

Unless there is some other reason, may be the tram, otherwise, I don't see the point.

One more thing, what was that white car doing in the tramway in the picture?
Some one was confused and drove into where s/he shouldn't be in. lol

Also those turbo roundabouts seem to work against two of the main advantages of roundabouts. Deflection, a collision between a circulating vehicle and an entering one would be a ninety degree angle hit instead of the softer deflected hit in a standard roundabout. Secondly the gap acceptance would need to be as big as a normal road because of the size of the area to cross.

Turbo roundabouts are nice, but one thing you can't do with them that you can do with a normal roundabout is drive around in endless circles. Hell, it's even conceivable that someone could get their car going around a roundabout in a circle, put a small weight on the gas, then jump out and let the car just keep going and going on its own, and run off and let the police deal with it. (Or you could stick around with a camera, and risk a reckless driving at the very least)

(I saw an episode of COPS from the 1980s with a car in a parking lot driving around around in circles without anyone inside - a cop had to chase it around and jump inside to get it stopped)
