<pre wrap="">My understanding is (was?) that the lane tag indicated how many lanes
there were in each direction, so '1' would indicate a road which was 2
lanes, 1 in each direction.
The definitive answer is rather blank on the matter:

That needed fixing then - Done. Because when originally conceived it was
always intended to apply to the number of physical lanes on the way.

As I'm new to this game, but very impressed by the bredth and depth of
the documentation for OSM, I'm quite surprised that lanes isn't better
described.<br>
<br>
I assumed it was the number of lanes in each direction, and started
tagging normal residential roads as lanes=1, then I found two spots
where there's onyl room for traffic in one direction at a time (over a
narrow bridge and through an ancient arch or folly). I was stumped how
to tag these, but when I saw someone say lanes was the total number of
lanes on that way (so in both directions for a non one way way) thought
this was great.<br>
<br>
Would it be too forward to suggest a Proposed features/lanes page. My
proposal would be that lanes is the total number of lanes on the way,
so ;<br>
<br>
Two Way residential road with one lane in either direction: lanes=2<br>
One way road: lanes=1<br>
individual carriageway for three lane motorway: lanes=3<br>
<br>
With a rationale that this would then clear up confusion, and help with
recording information such as single lane width restrictions, passing
places etc.<br>
<br>
I then assume that some of the highway tags could then assume a lanes
value (residential, unclassified, tertiary: lanes=2)<br>
<br>
I'll happily edit the page, but don't want to step on decorum !<br>
<br>
Thanks<br>
