yes, it's all, historically (without traffic lights) and currently (with traffic lights) a full featured roundabout (or at least it was until 10 years ago, don't know the current situation). > > > A solution could probably to improve the destination tagging on the > outgoing roads in sync with the directional signposts, so the instructions > can be "fork into Marchstraße towards Wedding". > yes, the particular situation of those big roundabouts is about the lane to choose when inside. You would want to be towards the inside where you don't exit and have to be towards the outside where you leave it. I believe your second example is a roundabout > > (Kottbusser Tor) No, it is not.

Most traffic is going straight and there's the subway above you when you turn, so it's generally a situation of low transparency (subway columns, shadow, etc.) and it doesn't really matter whether it's circular or not (you'll typically wait at the red light if you turn, so there's a lot of time to re-orient, IIRR). Großer Stern makes it easy to count incoming traffic / outgoing traffic I believe, it's so huge with many lanes and cars immitting that you can hardly miss a crossing road, even in the inner ways.
