Hello cserpell. I originally noticed that there was a missing oneway around the way feature (https://www.openstreetmap.org/way/862983432/history) but after further reading into the OSMwiki I saw that the feature on the ground met the criteria for a highway=turning_loop which has “a non-traversable traffic island in the middle,” (https://wiki.openstreetmap.org/wiki/Tag:highway%3Dturning_loop), which I placed on the end node here, as I thought a simpler modeling seemed best. A turning_loop meets that description more than junction=circular since there is not multiple road intersections there (https://wiki.openstreetmap.org/wiki/Tag:junction%3Dcircular). I agree however that it doesn’t meet the criteria of turning circle which has “either there is no central island or the island is traversable” (https://wiki.openstreetmap.org/wiki/Tag:highway%3Dturning_circle). Just for clarity’s sake, I wanted to point out that I did not tag this feature as a turning circle. Is that how you understand the OSMwiki Policy as well?
Curious about your thoughts on this. Thanks for your feedback.
