For unpaved roads with well-established ruts, I count the number of
ruts and divide by 2 to get the lane count.  This is useful to figure
out things like how difficulty it would be to pass oncoming traffic.

Tagging the width is useful in a different way: ruts two meters apart
that pass between a pair of boulders also two meters apart are far more
restrictive of who can drive there than ruts two meters apart on a way
that's been cleared an additional meter on either side.

highway=track.  There's no lanes, so leave that tag off.  Never heard of
narrow=yes before.

[Tagging] narrow=yes, vs lanes=1, vs width

2020-07-27 Thread Rob Savoye
 My entire county is contained within a national forest, and most of the
roads through residential areas are a single lane dirt road maintained
(sort-of) by the homeowners themselves. Often at the last house the road
becomes an unmaintained jeep trail, usually gated, and goes a really
long way into the forest. We use these for wildland fires and rescues
frequently.

  The question is how to tag the change in the road. Usually it becomes
"smoothness=very_bad", etc... The question is since it's now more of a
track used by jeeps, should it be narrow=yes, still lanes=1, or should I
use width=2m ? To me, lanes= seems to apply more to non 4wd_only tracks.
They're also usually narrower than the single lane highway too. The
width of the "highway" is important if you're trying to figure out what
size fire truck to bring to the wildland fire...
