Being able to speak each country's highway lingua franca would make it a lot easier for OSM to become the Rosetta Stone of maps simply from ease of classification. > This info is probably worth recording, > but legal status should go into a separate tag. > Legal status of roads in the US isn't quite as clearcut as it is in the UK, where the highway=* tag is literally equal to that country's legal classification, plus private roads with significant public passage and/or reach. Off the top of my head we have 1 country, 2 states, 34 tribes, 77 counties and 597 towns, plus MacQuarie Group Australia running the turnpikes and the Boy Scouts of America, Phillips 66, ConocoPhillips, or some combination of the three, and potentially scores more private entities, operating extensive networks of publicly accessible roads and highways in Oklahoma. And I generally consider myself lucky I have it *this* straightforward in the US. Texas likely has similar situations but throw in the fact that they have 7 different state highway systems before you get into at least 3 more (regional? state? private? unclear...) competing turnpike networks, sometimes running side by side on the same right of way (consider TX 121 with the George Bush Turnpike operated by the North Texas Transportation Agency running down the median). Simply starting with the HFCS and expanding from that (particularly on the freeway/expressway distinction, and having more levels between secondary and unclassified) would be a fantastic boon to dealing with this mess in a more concise fashion as it changes highway=* tagging from almost entirely subjective to subjective but within a limited range. Establish wiki pages describing how each region works and let the consumers sort it out from there. At an absolute minimum, we really need to establish values lower than tertiary yet above unclassified, and we definitely do need to make the freeway/expressway distinction.
