Turning circle is normally reserved for areas either at the end of the highway or along the highway which are enlarged enough for a car to turn: they are usually mapped with a node (the 115 which are not are likely errors https://taginfo.openstreetmap.org/tags/highway=turning_circle). This is something different it is a oneway loop at the end of the road.

Thank's, I think I've done this a few times...
Btw.: how would one map such a circular highway, which is neither a roundabout nor a turning_cycle. Simply map it as highway=residential/*? Oneway yes or no? -

Maybe what you have in mind is a https://wiki.openstreetmap.org/wiki/Tag:highway%3Dmini_roundabout ?

Comment from zehpunktbarron
According to the wiki a mini_roundabout should be mapped with a node and not using a circular road, as in this case.
Any ideas how this case (wich occured quite often in the mapRoulette chalange) should be mapped? -
Comment from Hjart
Ah, I guess I had better get some fresh air and a bit of sleep :-)
I've edited it now the way I usually do these.
Maybe a new tag should be invented to prevent the maproulette challenge from flagging it again? -
Comment from SK53
Operationally roundabouts determine priority at a junction: they typically need a minimum of 3 incoming & outgoing roads to be at all useful (of course there are cases with 2 roads whilst a 3rd is being built). These loops at ends of roads present no problems of this sort. I'd suggest the Maproulette challenge should add a test for numbers of input/output roads & if <3 then assume it is not a roundabout.
