This road-crossing is mapped strangly. The circular road is tagged as turning_circle=yes and there is also a node with junction=yes on the circular road.
It should probably be one of these:
junction=roundabout - a conventional roundabout
highway=mini_roundabout - a smaller roundabout with a traversable/mountable middle
junction=circular - not a roundabout but also round
Can someone tell what would be fitting here?
