I made Walkably, a free walkability map for 31 European countries.

Streets, paths and places come from OpenStreetMap contributors (ODbL). Every street gets a score from 0 to 100.

How the score uses OpenStreetMap

• Reach is 60% of the score: the real walk on streets and paths to eight daily needs, such as groceries, parks and public transport. A shorter walk scores more, and the second and third option nearby count too.
• Street quality is 40%: traffic, busy roads nearby, summer shade and slope.
