Turns out that the wiki page I mentioned isn't exactly how it's currently done in Belgium... On the NGI maps I have the rules they use to classify roads are almost the same as OSM, but they're using them much more strictly than us (I'm not talking about motorways or trunk roads here): NGI rules: N#, N##, R#, R##: primary N###: secondary Road numbers with letter suffixes use same classification as if the number didn't have the suffix. other important roads: tertiary OSM Belgium guidelines: N#, N##: primary N###: secondary Road numbers with suffix: primary or secondary whatever makes most sense R#, R##: primary or secondary, whatever makes most sense given the other roads that cross the R-road primary roads within an R-road become secondary primary/secondary changes possible if they make sense other important roads: tertiary N- and R-roads can be downgraded to unclassified or residential if they're really just a local road. So, drop all the "making sense" bits in the OSM rules, and we get the NGI rules :-) But the wiki page should be adjusted to get the above rules, as that's how almost all of Belgium is currently mapped...
