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!
cheers
Richard
