A Walk across Europe: Development of a high-resolution walkability index.

Summary: Not moving enough makes people sick, but it can be hard to get everyone to walk more. To help fix this, scientists made a special, highly detailed map of Europe to show how easy it is to walk in different places. They looked at things like street length, parks, hills, buses, and what kinds of buildings are nearby. They used satellites and computers to make the map very accurate, breaking the land into tiny squares. They found that big cities like Paris, Berlin, and Barcelona are the best for walking. This new map will help leaders and city planners build healthier, easier-to-walk towns for everyone.
