Re: [Tagging] traffic=fast
There's two things that distinguish HSLs/LGVs/NBSs: high maxspeed (typically 250-320, though some would include the new lines in Switzerland, which are only 200), and a lack of slow traffic (freight, stopping passenger services) because they have alternative routes. In some cases, you can get pretty high speeds without providing a second pair of lines, if traffic is sparse (upto 200kmh in the UK, upto 230kmh in Germany), so I think the presence/absence of a parallel slow route is something that can usefully tagged explicitly.

Re: [Tagging] traffic=fast
As every track segment has a maximum speed, why not just apply the existing maxspeed=* tag to the tracks? It is not clear to me whether your intention with traffic=fast refers to some attribute of the track itself, or the use to which it is put. Is it some official designation (from Network Rail)? I recall also seeing things like service=main_line (from memory) to distinguish main line from local tracks.

Hi tagging list, the Extended Conditions proposal has been shot down by a majority, and therefore there is still no official way of tagging quite a lot of things.

Re: [Tagging] Everybody is hiding?
While I agree with Frederik almost completely, the absence of a tagging scheme for conditions will have some unwanted side effects. A current example in my opinion would be this great and completely intuitive n2/n3 tagging that was just invented. It was already documented in the german access article, giving the impression that this is an accepted tag. If we would have a tagging scheme for conditions this could have been prevented.

I have a better one: why not stuff everything we ever want to tag into one big note tag, that would make all editors a *lot* simpler.

Re: [Tagging] traffic=fast
There's usage=main and usage=branch, but that is pretty crude. You might use that to reproduce the old BR network map (before Railtrack/NR went and made all the lines the same width). The norm on four track railways is for two of the lines to be designated the fast lines (or main lines on Great Western) and two to be designated the slow lines (or relief lines on Great Western). The naming isn't as clear if the pairs of lines diverge (eg the lines that bypass Redhill on the way to Brighton), but the idea is basically the same.

What I have seen from different people: - allows for an almost infinite number of keys: existing tagging shows that keys tend to cluster, e.g. maxspeed:(22:00-06:00) is in use 395 (!) times with 6 different values (putting this into perspective: meagre 4494 occurences of maxspeed:backward). Those clustering effects become even stronger with increased usage. - kills PostgreSQL database performance: when you preprocess your routing data, you have to do a linear scan over all tag hstores anyway. - difficult because of special chars: the only situation where this actually matters is when you search inside your editor – and in that case the ':' already requires you to quote your key, at least in JOSM - difficult to parse for computers: every programmer can tell you in a second that this is plain wrong - difficult to parse for humans: so far, everybody I talked to about this was able to grasp the meaning of maxspeed:(22:00-06:00) = 100 in a split second And – of course – my favourite: - un-OSM-y, don't like it Eckhart ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
