<div>Currently, with place=* and their relative info on a closed
way. I have written a proposal which aims to change this tagging
scheme: [1]<br>

<div>However, on a second thought, what you talk about is probably
a different concept. An agglomération has precise entry and exit
points, marked by the city limit sign - in Italy it's the same.
I know that many mappers don't want to have this defined by a
polygon, arguing that this would force consumers to do a spatial
query to understand what the speed limit is; however, the legal
constraint also involves other restrictions (e.g., no honking),
and a dedicated tag would work better in this sense. <br>

Hello everybody,<br>
<br>
According to my explanation (well, my government's definition), an
agglomération is just a set of roads and hence not an area nor a
multipolygon (there's no speed limit or parking restrictions in the
meadows ;-)) but, as I stated it, a plain relation. Yet, for larger
cities (without meadows ;-)) a multipolygon could be used to gather
already made subareas the day OSM will go recursing (nesting), but
what's outside the roads is undecided.<br>
The idea is that with a 30 driving rules list applying to an
agglomération (some 10 practically), you'd better have a global idea
of where it spans (e.g. highlight all its roads), entry/exit you
speak of, rather than ask yourself and OSM the question for every
new street you traverse.<br>
As well as for exceeding the speed limit, you can be booked in
agglomérations for parking partly on the roadside, or on the wrong
alternated side, not letting a bus leave its stop point, etc...<br>
Should there be a country-dependent agglomération tag, should the
driving rules be tagged one by one and should they be tagged on
every road or on a relation?<br>
Finally, should we try to tag everything or rather go and swim or
play tennis?<br>
<br>
Cheers, <br>
