I've been doing vast amounts of rural TIGER fixup over the past couple of years and this is what broadly seems to be what I've seen, bearing in mind standard practice in other developed countries and the idea that the highway= tag combines the importance in the highway network with some assurance of construction quality: * highway=motorway: interstate or other long-distance restricted-access road * highway=trunk: fast, busy State Highway or US Highway, often NHS/STRAHNET * highway=primary: major State Highway or US Highway * highway=secondary: other State Highway or major County Road * highway=tertiary: other through route, often a County Road, usually paved with centreline * highway=unclassified: rural minor route, sometimes a County Road, paved unless tagged otherwise * highway=residential: minor public road intended for residential access rather than through route, paved unless tagged otherwise (N.B. currently not safe to assume paved in rural areas where tiger:reviewed=no) * highway=track: ungraded or rough, but usable by some four-wheeled vehicles There are many, many variations, especially because the US doesn't have a single nationwide system like most European countries, but if I had to sum it up in a few words I'd choose the above. cheers Richard -- View this message in context: http://gis.19327.n8.nabble.com/NJ-mass-road-demotions-tp5894719p5897836.html Sent from the USA mailing list archive at Nabble.com. _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-us
