Hi Kovoschiz,

thank you for your responses. I think we need to find a solution for this in general.

If a place where I can turn around is mapped as a full road (for example https://www.openstreetmap.org/way/111301056) I would follow the wiki:

"Draw a closed highway=* way around the traffic island and connect it to the main road, giving it the same name. If traffic is required to flow in a particular direction around the traffic island, add oneway=yes. This method is preferred for large turning circles, because navigation applications decide whether the user is on- or off-route based on their distance from the roadway. This method also makes it possible to accurately map features inside the loop, such as parking spaces, trees, or a flagpole." Source: https://wiki.openstreetmap.org/wiki/Tag:highway%3Dturning_loop

I know that the wiki is not an absolute authority but it is at least a very good orientation. In this situation the description in the wiki matches most of the useage worldwide. Hong Kong is basicly the only area with ways tagged as turning_circle or turning_loop (https://overpass-turbo.eu/s/1wdZ). To be fair, there were a small amount of roads tagged similar to how you proposed, that I already edited. But at no point that was widly used.

I think we should folow the wiki here and don't use something like turning_loop=yes on ways. Because a road that loops around is just a road and does not need to be labeled as a turning_loop. Only if the turning_loop is tagged as a single node there needs to be an information that shows that we have a turning_loop here. My opinion is the same about the turning_circle tag.

I think both of us just want to improve the quality of the map. Do you know what I mean?

I would realy like to also read someone elses opinion on this topic. Maybe I am totaly wrong in which case I would of cause undo my last changes.
