This is overloading the maxwidth tag - sometimes it means legal, sometimes it means physical. This distinction needs to be crystal clear as it can be a matter of life and death (emergency vehicles can ignore legal limits but not physical ones...) so making its semantics so context-dependent is not a good idea...
maxwidth:physical is being used to tag the actual available width - which by the way is not the same as the distance between the kerbs or the width of the whole carriageway including paths/grass etc. That may be better tagged using width=* but the description of that in the wiki is not particularly clear. http://wiki.openstreetmap.org/wiki/Key:maxwidth:physical http://wiki.openstreetmap.org/wiki/Key:width --colin On 2015-09-08 08:44, Volker Schmidt wrote: > I use "maxwidth" to map the max width road signs, which represent a legal > access restriction, not necessaryly a physical acess restriction. > > I use "width" to tag the physical width of a road. > > If there is an object on the road that physicslly limits the width of the > vehicles you can use the tag barrier=block like this > > barrier=block > material=concrete > maxwidth=2 > vehicle=yes > foot=yes > Replace concrete with metal and you have a tag for your metal-pole width > restrictor > > Volker > Padova, Italy > > _______________________________________________ > Tagging mailing list > Tagging@openstreetmap.org > https://lists.openstreetmap.org/listinfo/tagging
