I like the idea. And although I like the simplicity, I think it might be worth somehow taking account for seasonable variability. There a number of quiet roads in the Lakes etc. atm that I wouldn't want to walk down in the summer. Perhaps the simplest approach would be using traffic:note to say when the last survey was made, allowing another user to average/update in an informed way.
Might there also be existing sources of this data (for some roads) 'owned' by local authorities or highways agencies; these are guesses, I don't know who does this kind of surveying. > I think in my part of the SW the large majority of highway=unclassified would be <=1 car a minute average so just from a tagging perspective > it would be a lot easier just tagging those few that are busier. I agree, working with assumed values based on way classification would make it a lot easier.
