Bottom line is it is subjective. Be friendly, make a compromise and have
This is something that has shown up a few times that I recall. What I
remember from that is primary rely on "ground truth" but it can be adjusted
for map consistency and other extenuating factors. Unfortunately that
comes under the judgment of the mappers.
Examples: I remember there are Interstates that are actually unpaved in
places, but tagged like all the rest of the interstates with perhaps
surface=unpaved ect. I think Alaska might be good examples of this but
haven't checked into it myself. Another is where the road conditions
change for a mile or two before reverting back. Especially if this happens
several times in a row it is usually desirable to keep one classification
instead of going back and forth. Relative conditions of the area also come
into play. It isn't always a question of the road at that specific point
meeting a set of requirements.
Specifically for your example of US 7 and route 2. Both seem to connect
the center of burlington to other major roads and populations centers, not
just a local road.
My answer that isn't an answer.... :p
