I have seen nothing documented, but if you look on tagwatch[1], there are 50 instances of people using a key of shoulder, with values of no, yes, narrow, and 46 instances of shoulder:width with values in meters.  So, you could probably formalize something and propose it on the OSM:talk [2] or OSM:tagging list [3], and then on the proposed features page [4]

I don't think there is any formalized way to indicate traffic other than looking at the class of road, (residential, tertiary, secondary, primary, trunk, motorway).  I see many instances of a traffic key on tagwatch, with very complex values, but no idea what it's about, (e.g. traffic:hourly:23:Tu:winter:snow = 376/7:30)

Again, if you have an idea about how to reasonably mark it up, (daily traffic volume, accident rate, etc) propose something for people to comment on.  I, myself, would like to have some way to mark up which streets are better for cyclists.  I know of a street near my home that is marked as a cycle route, but a 3 block stretch of it is so narrow that buses going through in opposite directions will wait for the other to go through before they proceed. So, it really does feel too narrow to be a good cycle route.

The tags that currently exist that would be useful are highway= for the different classes of road, cycleway=lane for bike lanes, maxspeed= for the speed limits, and lanes= for the number of lanes in the road as a measure of traffic.  Unfortunately, I don't think most places have added speed limits or number of lanes.
