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)?
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
