I bet this situation is not so rare in other countries with a significant amount of 2-wheeled traffic and old urban structures (and not so much regulation). I believe that this kind of way is significantly different from a residential street and should have its own tag (also because it makes using the data for rendering and routing much easier). I'm using (and I know others do as well) highway=service with service=alley for these. They are not the typical service way, because legally they are roads, often the only road to access the buildings along it. If there is maxwidth signposted I obviously add a maxwidth tag as well, but often there isn't (ideally I could measure the narrowest part myself and add this as width, but I typically don't do it, and width is not the only criterion, sharp bends and corners also come into play). cheers, Martin _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
