Topic: How to tag ways that are grouped in a "zone". Sensible default values Specific default values by country related tags and concepts: zone:maxspeed=[country]:[20/30/40/50/...] zone:traffic=[country]:[urban/rural] living_street Tempo-30-Zone low_emission_zone limited_traffic_zone and so on... / DISCUSSION / althio forum <althio.fo...@gmail.com>: >> (1) proposing tagging for zone like ZTL: Martin Koppenhoefer <dieterdre...@gmail.com> wrote: > there is actually a proposal for this kind of zone, to be mapped as a > polygon, useful e.g. for rendering (with name, ref, etc.), but probably not > very transparent to inherit access-tags to ways from this. > http://wiki.openstreetmap.org/wiki/Proposed_features/boundary%3Dlimited_traffic_zone This is not what I am proposing. My tags are for streets highway=*; not for a polygon. With direct tags and no need for inheritance from polygon to ways. Go beyond my summary and see explanations in my post instead: >> So possible tag for a ZTL in Italy could be: >> highway=IT:limited_traffic_zone (scheme similar to highway=living_street) >> OR >> highway=residential/pedestrian + zone:traffic=IT:limited_traffic_zone >> (scheme similar to zone:maxspeed=FR:30 or zone:traffic=DE:urban) As you mentioned these schemes zone:*=[country]:* follow practical tagging on each street not "zones". It is not the primary tag, just an additional tag "+ zone:*=*" and merely indicates that a particular way belongs to a real-world zone. > 2014-12-03 6:35 GMT+01:00 Friedrich Volkmann <b...@volki.at>: >> highway=ztl >> or >> highway=pedestrian+pedestrian=ztl, and some comment [...] On Wed, Dec 3, 2014 at 12:18 PM, Martin Koppenhoefer <dieterdre...@gmail.com> wrote: > [snip... needlessly harsh tone... snip] > A ZTL is typically defining access restrictions, it has nothing to do with a > road class. Several road classes (from motorway to residential and special road types like pedestrian, living_street...) could benefit from sensible defaults. AFAIK some road classes do already imply defaults. Furthermore these defaults can be country-specific. Access restrictions could similarly be included as defaults in a road class. Hence I guess Friedrich's proposal highway=ztl or mine highway=IT:limited_traffic_zone. > I wouldn't prefix this with IT because this is not something that gets > specified or enabled on a national level. + > these do have nationwide the same rules and conditions, unlike ZTLs. Other countries may have similar features and benefit from the same tagging [limited_traffic_zone], sensible default values could be set globally and for each country [IT/UK/...:limited_traffic_zone]. > you won't gain anything with this tagging, because every ZTL has its own > restrictions, times, exceptions, etc. You could go a long way with the tagging *=*:limited_traffic_zone and some default values like: + motorcar=private/destination + emergency=yes + psv=yes + disabled=yes So back to your scheme: highway=residential + motorcar=private + motorcar:conditional=yes @ (18:30-07:30) + emergency=yes + psv=yes + disabled=yes would be reduced in this ideal case to highway=IT:limited_traffic_zone + motorcar:conditional=yes @ (18:30-07:30) OR highway=residential + zone:traffic=IT:limited_traffic_zone + motorcar:conditional=yes @ (18:30-07:30) Added benefit is that when a contributor is simply tagging "limited_traffic_zone" we have easily and immediately a lot of real-case situations correctly handled. And everything can be refined with further minimal tagging including conditional time and local exception rules. / RANT / Geez... Martin, it would be better if you reply to the full-extent discussions and not to the short statements from a summary. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
