Walkably

How walkable one street spot in Europe is (31 countries). Give an address, or lat and lon. Returns the Walkably score from 0 to 100 (60% reach, 40% street quality; a street quality under 40 caps the score at 69; the score is never more than 10 points above reach), the reach and street-quality parts, the share of the country's places it beats, minutes on foot along real streets to each of eight daily needs (groceries, food and drink, shops, health, school, parks, culture, transit) with the nearest place and a Europe-wide verdict, and a link to the spot on the map. Each score covers a six-sided street cell about 95 m across. Addresses are looked up with Photon (komoot), a free OpenStreetMap address search.

A city's typical Walkably score (0 to 100, for where people live), its rank among the cities of the same country with a Walkably page (for example rank 1 of 36 cities in Spain), the median walk to each of eight daily needs, and the five best and five least served areas of the city, exactly as on its walkably.org city page. 477 cities in 31 European countries.

For a city with a district ranking page (today Vienna, Hamburg and Rome): every district that has a score on that page, ranked by Walkably score, with reach, street quality and minutes on foot to eight daily needs for each. For any other city: the five best and five least served areas from its city page, and it says so.
