Surfaces are graded for small wheels from OpenStreetMap survey data — asphalt, concrete and paving quality, with anything over 30 mph and every A-road excluded, because a road being smooth and a road being safe to skate are not the same thing.
Plus 4 more that OpenStreetMap has no name for — they are on the map with the area they sit in.
