<div dir="ltr"><div><div>Thank you, Minh, for the in depth discussion of all the interconnected issues with highway classification. There is definitely a lot to consider and I think your assertion "that this isn't a simple <br>
matter conducive to simple solutions" bears repeating. <br><br>As a fellow Vermonter, I agree with Adam's assessment of the NHS in our state. It seems like quite a good basis for the higher level OSM classifications here. However, I'm not surprised to hear that there is significant variation and in some states it may be much less useful. It seems to me that a matrix taking both the highway system (Interstate, US, state, etc) and the FHWA functional class into account would at least be a good starting point in the decision tree for how a road should be classified in OSM. Waze has something like this in their classification guide: <a href="https://wazeopedia.waze.com/wiki/USA/Road_types#Quick_reference_chart">https://wazeopedia.waze.com/wiki/USA/Road_types#Quick_reference_chart</a><br></div>I took a stab at creating a similar chart for OSM classification here:<br><a href="https://docs.google.com/spreadsheets/d/1UQpA8pDqiJ6HL3Z96zmjSNAg9CVwEYxJiZnSj4KA5wI">https://docs.google.com/spreadsheets/d/1UQpA8pDqiJ6HL3Z96zmjSNAg9CVwEYxJiZnSj4KA5wI</a></div><div>I'd be interested to hear what people think of this approach. I'm sure it would need to be adjusted and made more detailed. I would also only consider a chart like this an initial guideline to allow for edge cases and exceptions where roads could be upgraded or downgraded as appropriate.</div><div><br></div><div><br></div><div><div><div><div><div><br><br></div></div></div></div></div></div>
