Жилая зона (residential area) is a territory in settlements, the beginning and end of which are indicated by road signs 5.21 and 5.22. (Look section 17 of traffic rules)
Велосипедная зона (cycling zone) is an area designated for movement of bicyclists, the beginning and end of which are indicated respectively by signs 5.33.1 and 5.34.1.
Дворовая территория (courtyard area) is not official definition in traffic rules. It means a space bounded by buildings around the perimeter, inside which can be located playgrounds, places for recreation, green spaces, local driveways to houses, schools, kindergartens, etc. Unlike the residential area, it isn’t indicated by road sign 5.21. And it haven’t road network, only local driveways.
So Жилая зона (residential area) is highway=living_street
Ah, so are motor vehicles allowed “as guests” in a Велосипедная зона (cycling zone)? Or are they not, unless signed otherwise? If it is bicycles-only, it is bicycle_road=yes, if it is otherwise, it is cyclestreet=yes
Then, I guess Дворовая территория (courtyard area) would be tagged with highway=service
Say, because of an ongoing discussion about the highway=service tags and possible subtags, do you have any (street view) photos of such courtyards (Дворовая территория )? I can’t imagine like this would look.
