Re: [Tagging] agglomération
Simone Saviolo: if you need to tag the maxspeed anyway, then what's the point of that tag? It's not about the maxspeed, but the area that supposed to be considered urban, and interesting in itself. The rural/urban distinction affects other rules, even outside of the traffic code. Here the traffic rule differences are, at least the following: - no honking in urban areas, except in case of danger - no unnecessary(!) driving in urban areas - no parking on marked priority roads in rural areas. - in rural areas, only marked junctions (guideposts or a traffic sign) forbid overtaking - different rules for lights in parked cars - stricter rules about distances between slow vehicles in rural areas Examples of non-traffic implications include - dogs always on leash in urban areas, and one must collect the poop (with conditions). - (disruptive) drinking forbidden in urban areas - smaller traffic signs allowed in urban areas, with less spacing between them, and between them and the road Even the state funding for municipalities depends somehow on the population within the urban area, among many other things. -- Alv ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

Re: [Tagging] agglomération
Had forgotten the horn one, although the rule says 'except to avoid an accident', and there are really few other valid uses for the horn. I did look up the full beam rule, and cannot find one. All I can find is a rule that says 'you must not use lights in a way to dazzle or cause discomfort to other road users, including pedestrians, cyclists and horseriders.

Re: [Tagging] agglomération
Hi, 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 not match. 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.

So I was glad I finally learned how it could/should be done in one of the many discussions started by Papou. zone30 are mostly within built-up area, zone50 and zone70 aren't. I think it's important to distinguish between zoneXX and built-up area as they occur mostly independent from each other, so the namespaces also ought to be independent. We could use source:maxspeed=BE:zone30 instead of source:maxspeed=zone30, but since a street already gets zone:traffic=BE:urban/rural, the BE seems less important in the source:maxspeed tags.

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? Cheers, André.

Re: [Tagging] agglomération
What I'm doing right now is tag the roads inside this zone with maxspeed=50 and source:maxspeed=city_limit. This doesn't fit entirely, as it doesn't only influence maxspeed. Maybe adding a tag city_limit=yes would be more appropriate? Besides there is a conflict when inside those city limits there is a zone30. I'm tagging those with maxspeed=30 and source:maxspeed=zone30. The zone30 also has some extra consequences, besides maxspeed though. Would it be more correct to use zone30=yes? We also have zone50 and zone70. I have been tagging the location of city_limit signs for several years now, but since we didn't have a tag for it, I simply used note=city limit or bebouwde kom (nl). I hope a proper way of tagging them will come from this discussion.

An agglomération is more than that, and I don't think there currently is an agreed way to tag them...

When a new tag is created, chances are that no software will reconize it right away, but by explaining somewhere how you tagged it in a clear (and unambigous) way then everyone doing a software will know how to recognize it.
