As I am against always changing the subject line of discussions, I
resent with the original one.
But it's also to add that, in my opinion, the tagging must respect the
categories that the national law defines (our code de la route). There
is no point in trying to forcefully adapt foreign concepts if they do
I don't think there's a concept of built-up area in the Belgian law and
I don't think there's a difference in the definition of an agglomération
whether it resides in a city or in a village (even if rural sounds like
village, this is not poetry).
This all, obviously, doesn't prevent a specific tag like a lower speed
limit overriding the global one.

Great finding From Lauri indeed !!!
But regarding this, where is the complete zone:traffic=BE:* list? (just
In Belgium, we have more than urban/rural/motorway/etc.
route pour automobile=*?*
zone de rencontre=*?*
chemin réservé à la circulation des piétons, cyclistes et cavaliers=*?*
rue réservée aux jeux=*?*
Abords d'école= Zone 30=*?*
Each with their regulations details.
I was lately "sent" to map an alleged Zone30 area and there was no Zone
30 but a /*zone résidentielle*/ which is equivalent maxspeed-wise but
not other-wise (other-regulations-wise).
If we had a tag such as *INCLUDE:BE:...:urban* etc. with which the
programs would fetch all the relevant tags like *maxspeed* per zone type
from a well known per country or WW (world wide) database object (1)
then we would have a clear list and we could tell the government that
they can change details any time without sending us to work everywhere.
How could otherwise programs that are supposed to use the OSM data make
sense of a such ever changing global notions without breaking them down
to well-defined concepts such as speed, bicycles, etc...
That would please both the global view and the piecewise one.
Wouldn't that stop the zonebabel?
(1) for example some well-known BE relation that would contain a
role=*zones* or *traffic* member to a relation that would similarly
contain rural, urban, etc. pointers to nodes that would contain the tags
