 But they nearly all run nearer to one of those directions than they do
 to any of the others. If you want to say that a North East road is one
 way, you can call it North or East - there is no contradiction. Pick the
 one it is closest to, or either if the road is really exactly at 45
 degrees.


Umm... What happens if the road is not straight, but in fact winds around
quite a bit? Then left and right are still unambiguous, but cardinal
directions are definitely not.

 I think it depends on the perspective you take. To me, the nodes and ways
should follow the physical world as much as possible--the road didn't change
just because the speed limit changed, so why chop it up? Either way we go,
it's going to require good editor support for this, but to me, it's easier
to manage one long way than to hunt down and select each constituent way if
I want to change some aggregate property (I've done some editing of the
TIGER data). I think it also does more to encourage an iterative,
incremental approach to data refinement--first get the physical tracks down,
then add speed limits, lanes, surface information, etc. I know, it would be
great if all that stuff was done at once, but putting an emphasis on getting
the physical ways in place first does more to expand OSM coverage and make
visual progress to the renderers, and makes OSM more useful to more people,
sooner.

I am not really sure about this. Just splitting the ways seems
less complex?

An obvious problem with your proposal seems that it does not
specify what happens with conflicting segmentations (ie,
way A-B-C-D-E and segmented relation X says from A till D is
90kmp maxspeed and segmented relation Y says from B till E is
70kmp maxspeed.

 In Canada and the US, Avenue is usually meaningless. Sometimes
 Avenue is exclusively used to refer to roads that go in a certain
 direction (like north/south in New York City) but in Toronto Canada,
 roads of all types are arbitrarily called street, avenue,
 boulevard, drive, etc. with no rhyme or reason. It definitely has
 nothing to do whether there are trees in the middle.

 Perhaps this is true in the UK but it definitely isn't true in Canada or the 
 US.

The same generally applies in the UK, although minus boulevard.

Hehe. The last time I said on #osm we got rid of segments, now
let's get rid of ways I met stiff resistance :)

But moving to relationship will not help you getting rid of
direction : to represent a way you need to order your nodes and
order implies direction.

 (a) the direction is too easily changed, sometimes by mistake

That is a problem with the editors. I think we are in a good position
to improve on this.

well, I' quite new to this kind of things, but in my opinion a line of
trees is quite a more important landmark than a concrete shoulder.. If I
was to give direction, I would for sure say take the avenue with the
trees, while of course I wouldn't in the other case. There is even an
italian expression, viale alberato which specifically describes an
avenue with tree lines..

and, I agree, a 3d map view with rendered trees would be very cool ^_^

A bigger question.

I see someone has already proposed landuse=tree_row
   http://wiki.openstreetmap.org/index.php/Proposed_features/tree_row

I wanted a tag for miscellaneous bits of open grass with trees and shrubs
http://wiki.openstreetmap.org/index.php/Proposed_features/Misc._urban_open_space

but the most common comment on the mailing list was I don't understand 
what the difference is between this and a park (though no one has put 
that in the wiki page). So I gave up, even though I think they are very 
different. I've tagged my bits of open space as parks even though they 
aren't.

Maybe I should resurrect this.

David

  err... is a line of trees a park?

 it ususally is just a line of trees.

I'm used to see wider green areas as part of big avenues (between the main 
road and the aux. road). See:

All those should use a leisure=park area, IMHO (and it will, as soon as I have 
some time to do so).

If it's *just* a tree line, with no noticeable green area... I guess that the 
proposed landuse=tree_row would apply better.

 Any suggestion about how to render all this? Even an example of an
 already done similar object could be useful.

Make one way per type of way in the avenue. E.g.:


-- -- -- -- --   highway = service
Tree Tree Tree Tree   amenity = park
- -    highway = primary
- -    highway = cycleway
- -    railway = tramway
 - -   railway = tramway
 - -   highway = cycleway
 - -   highway = primary
Tree Tree Tree Tree   amenity = park
-- -- -- -- --   highway = service

*If* the central way does *not* have a division between the lanes, then join 
the two ways, and specify oneway=false.

Just a suggestion, though.
