I'm for verbal description rather than a number - easier to understand.
If I come across a road marked 'smoothness=medium' and later come across 
a road with worse smoothness I can see which way to go with the verbal 
value, if the value was a simple number I'd nave no idea..and may skip 
the data entry due to time limits, laziness and added complexity.

Some decades ago I looked at road classifications .. for 'off road' 
vehicles, I was after erosion problems at the time ... I think there may 
be some classification system for smoothness .. certainly there was for 
the load bearing of a terrain. Some US military publication had some 
tech data in it .. amonst some 40 odd publications I skimmed through at 
the time. Might try to look that up? Depends on how easy it is to find 
it in the library catalogue ... it is better than google .. but they 
have a different system of course.

Photos help ... but I'd like some word guidance too.
