[OSM-newbies] Pavements, pedestrian crossings, road widths, house numbers, parking restrictions, speed limits, public transport timetables

One more thing...

Another aspects to pedestrian routing is "is it safe to walk along 
there, even though I know that there isn't a pavement at the side of the 
road"?

This post:

(and its followups) was a discussion about how to get traffic levels 
recorded.

There's also "is this road lit at night":

I believe that at least one online map uses "lit" data.
