As a German I am not sure if I understand what shoulder means.
In Germany we have a traffic_sign "Seitenstreifen nicht befahrbar"
and one with a pictogram:

Dou you think that shoulder means what we call "Seitenstreifen" ?

Betreff: [Tagging] Formalising shoulder tagging

Hi all,

At present there is no documented standard for tagging highway shoulders.

We have http://wiki.openstreetmap.org/wiki/Shoulder with
shoulder=yes|no, which has been in 'draft (under way)' since 2010. In
Australia, cycleway=shoulder appears also to be used.

Taginfo stats are:
        shoulder = *                    7120, of which:
                shoulder = no           3230
                shoulder = yes          2743
                shoulder = right        964
        shoulder:width = *              1794
        shoulder:right = *              1047
        width:shoulder = *              843
        cycleway = shoulder     502

There are several gazillion miles (approximate value) of roads with
shoulders around the world. We should have a way to tag them.

I'd therefore suggest simply formalising the most popular existing usage
and the one on the wiki page - that is, shoulder=yes|no. As a default,
I'd suggest shoulder=yes is presumed as the most common real-world
situation, i.e.:

        "A paved shoulder, wide enough to be used as an emergency
         refuge for cars, and for through passage by bicycles."

(Narrow shoulders can of course be tagged with shoulder:width, gravel
ones by shoulder:surface, and so on.)

There are of course many refinements one could imagine, for peak-hour
shoulder running, buses, etc. But since "the perfect is the enemy of the
good" etc., I'd like to get the basic shoulder=yes|no agreed first.

Speak now or forever hold your peace!
