My understand is that highway=primary/secondary/unclassified/etc. is based
on function. It says nothing about the physical configuration, other than
it is suitable for a 2-track vehicle. See my comment below about unpaved
roads in many parts of the world.

I am willing to change my mind, but I would like:
1) Internal consistency within a definition.
2) Consistency over time (from week to week, month to month, etc. obviously
things can evolve over time, but we don't want to "ping-pong" back and
forth) I don't like having the same discussion over and over again. I
asked this same question about a trail in a nearby park (Natural Area) a
couple of weeks ago on this list and received a largely different answer
from the one I am receiving today. Perhaps it is just that different
people are reading this list today.
3) Precise. It can't be something like "a driveway is highway=service,
service=driveway, unless it is too long or too rough, or *seems* like a
track, in which case it is highway=track" One mapper I corresponded with
via change set comments literally told me he mapped a driveway as a track
because it seemed track like to them.

if it goes to a barn or a house! But I can’t tell without trespassing, how
can I map it?
I can generally tell the difference between a barn and a house based on

look exactly like a track. Mappers in all the areas I’ve looked at will tag
a way that is unpaved and about the width of a four wheeled vehicle as a
track regardless of current use. Maybe it is being used as a driveway.
Maybe it is being used as a bicycling/hiking/equestrian trail. Maybe it
accesses a field. Maybe it hasn’t been used for a while and just hasn’t
decayed or been overgrown into nothing. Who knows? But it looks like a
track. Saying that the way “isn’t for forestry or agricultural use” so it
can’t be a track is worthless: Real world mappers have voted otherwise with
In many parts of the world, higher classified roads (primary, secondary,
unclassified, residential, service) are going to be unpaved and somewhat
rough. That includes some parts of the US I am familiar with.
