Agree partly. It's not meaningless, but it get's ambiguous very often.
Take traffic signals as one example where the direction might be used:
Besides an intersection someone could add the traffic lights on the four
individual ways (instead on the intersecting node itself).
This matches the installation of the individual lights and the stop
positions, but it produces wrong results without a direction tag.

The drawback of that is, that someone crossing the intersection straight
meets two traffic lights, which is wrong of course. The mapper therefore
might decide to add direction-tags to them, as each traffic light node
is relevant and applied only for one of the two directions.

Looks perfect now - all four traffic lights are mapped separately where
they are, routing for cars works great (provided that the direction tag
is known and supported by routers).

Enter of the next mapper: He want's to add the footways and cycleways
that cross the streets using the pedestrian traffic lights integrated in
the traffic lights mentioned above.
As a result the nodes previously mapped with a direction are shared by
two ways, and it's hard to determine what the direction tag refers to,
as of course crossing for pedestrians is possible and meaningful for
both directions.

 I haven't examined any
 uses of the tag on a node, but I can imagine, for instance, that a node
 in a way with a direction attribute might be used to represent a
 road-sign that applies only to traffic on the way passing that node in a
 particular direction.
For other traffic signs it's the same, and that's why we usually map the
road signs meaning on the road that is affected by it. (The sign itself
may be mapped as such, as an obstacle and a physical object next to the
street), while maximum speed, maximum dimensions (width, height,
weight), oneway access, access restrictions and so on are mapped on the
where they hold.

Here the direction is useful (look at the oneway=yes tag), meaningful
and not ambiguous; on nodes it is or get's very lightly without tagging
mistakes.

Ok, we can take a split between unconnected nodes on the
left-/right-hand-side of the road and nodes being part of a way. The
first are less ambigious but you still need to know the driving
directions where as the latter ones just won't work properly with
forward/backward.

To make it less ambigious and easier I would deprecate forward/backward

 completely for nodes and advice to use cardinal coordinates for all nodes.

I think that would be ok for traffic_sign:direction=*,
but not for traffic_signals:direction=* or direction=* when used with
highway=stop/give_way, because it wouldn't be as easy to know to which
highway's direction the highway=traffic_signals/stop/giveway applies to.

IMHO we should use relations for cases like this (see turn restrictions,
 via nodes, for reference)

Hmmm. The examples I've seen on the map and as I recall the traffic_signals 
portion of the wiki for complex intersections the traffic signal node is not 
placed where the signal is but rather where a vehicle must stop for the signal.

That is prior to the crosswalk. So if a second mapper comes along and adds 
footways then those footways should not go through the vehicle traffic signal 
nodes. I haven't seen an example but it seems to me that the pedestrian signal 
should be on the new footway where a pedestrian should wait. So there should be 
no confusion as to the meaning of a traffic_signals:direction=forward/backward 
tag.

At least for the case of traffic_signals:direction=forward/backward, the use 
should be unambiguous as they are currently defined.

Cardinal directions could work but I wonder about errors and ambiguity that 
might crop up in the consumers of this data. I suppose that there might be some 
very detailed map renderers that wish to show all signals, signs, etc. But I've 
assumed that this information was primarily intended to make routing more 
accurate. Forward/backward along the direction of a way is information any 
routing algorithm has immediately at hand. But what about a road that makes an 
sharp bend just before the intersection? We sometimes have these here where two 
roads come in at an angle and the traffic engineers decided to make the 
intersection as close to a right angle as possible for safety reasons. I can 
see a human mapper assuming the tangent the road has before and after the 
intersection as the cardinal direction but routing software might not easily 
figure that out.

Is there anyone following this thread that is doing work that consumes these 
tags? If so what is easier and less error prone to process?

Regarding using relations, given the multitude of human errors introduced into 
existing relations by people making changes, I'd argue that very good support 
for traffic signal relations be built into all editors if this is the direction 
people wish to take. That does not seem to be the case currently for many types 
of relations, even simple ones like route relations.

Martin, throught you wrote something different about benches last week
on talk@osm

If we proper define the direction, there is not problem with direction=*
on nodes. E.g. directions for benches are taken from a sitting position
and in general the wiki talks about facing the direction which in my
understanding would be the opposite direction of your looking/driving
direction.

  Yes, it does make sense and is useful for benches and
 traffic_signals.

   Hey
  
   As I had much fun with the last subject (noexit), I just can not
 hold
   myself back to jump into another bee nest.
  
   I read on the wiki page [1], that direction=forward/backward are
  valid
   values also for nodes.
  
   Could someone please explain me, how this can work.
  
   I only find some major reasons not to do that:
   * You always have to look at the parent object to determine the
   direction
   * There is no editor supporting this tag when reverting a way
   direction
   * I am not allowed to split a way at this point which is another
   unneeded burn and once again you need special editor support
 which is
   not present.

 I have never used this key before because of the drawback you mentioned:
 There is no editor supporting this tag when reverting a way direction,


Does anyone else think that the reverse tool should be removed from
editors? There's no real use for it, and it only gives us problems when new
mappers use it. If someone really needs it, they can download a JOSM plugin.

Have to disagree here. There are plenty of real uses for reversing a
way, and not everyone uses JOSM.

i agree as well. i use the reverse tool, well, not all the time, but
frequently enough
that i think it definitely belongs in the editors.
