Thanks a lot for surveying the situaton (wow, that was fast) and even taking some pictures! Now, I would even say, we don't need any restriction there in OSM, because a turn into Rüdersdorfer Straße isn't allowed anyway (access=no + exceptions; in the wiki it says: "There is no need to restrict turning into the wrong way of a one way street." (http://wiki.openstreetmap.org/wiki/Relation:restriction) I think it's quite similar here). But perhaps we could add traffic_sign=* (http://wiki.openstreetmap.org/wiki/Key:traffic_sign). So we could do that, close the note and have a look at it somewhen later when all constructions are done. Do you agree? Or what else do you suggest? Thanks again for surveying - cześć
