[Talk-GB] Trunk vs green-sign routes in the UK
Hi, This is kind of a tagging question, but is UK-specific and pretty straightforward so I thought I'd post it here -- apologies happy to re-post if felt inappropriate. I've noticed a couple of roads in the UK being downgraded in OSM from trunk to primary on the basis that they are not trunk in the County Council / DfT maintenance sense. They are, however, green-sign primary routes and are clearly of greater importance than your average white-sign route. The ones I've noticed are the A354 (Salisbury-Blandford) and A22 (Greater London boundary to E Grinstead). Strictly speaking these changes are correct, as trunk in the UK implies being run by the DfT rather than local councils (N.B. a large number of former trunk routes have been devolved in the past 10 or 20 years). But the OSM Wiki says to use the trunk tag for primary A road (green signs), and this would certainly make more sense from the road-user perspective. Is there a consensus on this? If not, might it be a good idea to introduce a new tag signifying a UK green-sign route, and for these to be rendered as such in Mapnik (i.e. in green, the same as trunk routes)?

the wiki is the long-accepted approach: use highway=trunk for green signs - ie the primary (sorry) route network On Mon, Apr 22, 2013 at 2:44 PM, David Fisher djfishe...@gmail.com wrote: Hi, This is kind of a tagging question, but is UK-specific and pretty straightforward so I thought I'd post it here -- apologies happy to re-post if felt inappropriate.

Yes, there has been a consensus for at least the last six and a bit years now that trunk in the OSM sense means green signed primary A road and primary means white signed secondary A road. Which is why the wiki says what it does. Tom -- Tom Hughes (t...@compton.nu) http://compton.nu/ ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb

Ok. So I guess I should message users Trubshaw (re A354) and UltimateKoopa (re A22), then. Thanks guys.

Re: [Talk-GB] Trunk vs green-sign routes in the UK
Yep, as others have noted, the Green Sign = Trunk Road is the age old convention. If you want to add details about who maintains the road you can use operator=Highways_Agency (the second highest use of the operator tag apparently [1]). We don't have a tag for indicating that the signs are green (hence it would be nice if people stick to the convention).
