The Surgeon General announced the numerous and profound health benefits that Americans can gain simply by walking more. He made a Call to Action for more walking, but also for better walkability which means environmental conditions that makes walking safe, convenient, and enjoyable. “Walkability” is used in different ways. City planners refer to walkability as designing neighborhoods so people can walk from their homes to common destinations like shops and schools. There is much research showing that people of all ages do walk more for transportation in walkable neighborhoods, but the layout of communities is very difficult to change.
