<p>+1 here too, and a little bit of the same concerns expressed by
Andy (<a class="moz-txt-link-freetext" href="https://xkcd.com/927/">https://xkcd.com/927/</a>)</p>
<p>BTW, in the Italian mailing list there is currently a thread
discussing if and how we should tag highways according to what are
the official categories in the Italian Traffic Code (<i>Codice
della Strada</i>) are.</p>
<p>There the concern is most about how to tag an official
classification (<i>something that is implicit in the tag value in
UK, if I'm not mistaken</i>) instead of a "descriptive
classification".</p>
<p>But other concerns are emerging too (<i>at least in my head!</i>),
like the administrative responsibility under which a given road
falls (<i>state, region, province, municipality, private</i>) and
ad-hoc values as input for the router (<i>s</i><i>peed limits,
traffic density, etc. *OR* a comprehensive "preference"value </i>).</p>
<p>Keep on going!</p>
<p>Cheers,</p>

I think we should decorrelate the attributes of a road : its
administrative class, its importance in the road network (at
least 5 levels), its physical characteristics (motorway-like,
two large lanes, link=yes ...), possibly its traffic
characteristics.
<br>
<br>
So we can tag a secondary motorway or a primary road through a
residential area or an official motorway with pedestrians
actually walking on it.
<br>
<br>
So that we’ll unify osm road classification through the world
(remember the highway=trunk issue ;-))

It's a noble aim, but unfortunately the first thing that springs
to mind is <a class="moz-txt-link-freetext" href="https://xkcd.com/927/">https://xkcd.com/927/</a> :)
<br>
<br>
However, some of the stuff on
<a class="moz-txt-link-freetext" href="https://wiki.openstreetmap.org/wiki/User:Djakk/new_tagging_scheme_for_roads">https://wiki.openstreetmap.org/wiki/User:Djakk/new_tagging_scheme_for_roads</a>
I definitely agree with, and in some cases actually do do myself -
like trying to capture the physical characteristics wherever
relevant.
