Hi all, been following the thread, just hadn't yet taken the time to write.
Part of the confusion is the lack of a 'definitive' wiki page. Here are some links, partly contradicting each other: https://wiki.openstreetmap.org/wiki/United_States_roads_tagging https://wiki.openstreetmap.org/wiki/United_States_Road_Classification https://wiki.openstreetmap.org/wiki/US_highway_signs If we can direct some of the energy exposed in this thread in consolidating / cleaning up these pages, then perhaps this discussion won't recur as much in the future. Here's my take, mostly reiterating what is already mentioned by some before: * Relations using network= and ref= are the preferred way of capturing route information, not ref= on individual ways. The relation pages[1] can help. * The hierarchy used in network= is US:I for interstates, / US:[2 letter state ISO] for state routes, and US:[2 letter state ISO]:[County / parish / borough name] for county level routes. * the ref= on relations only contains the number. Any data consumer composes the full route shield / name from the network and the ref tags. * We don't quite know how to deal with bannered routes yet. * Renderers affect how people map whether we like it or not, so ideally we should have a very visible renderer that follows these conventions. Once things settle down after SOTM US, I am willing to commit some more time to getting a really nice US tile server up and visible on map.openstreetmap.org (or something similar).
