What is walking distance?
How far do you walk? 1/2 mile, 1/4 mile, 6 minutes, 30 minutes? What is distance you will walk before you start to think that maybe driving or taking a bus makes more sense?
It turns out that walking distance has more to do with what you are looking at, and less to do with how far you need to go.
Walk Appeal promises to be a major new tool for understanding and building walkable places, and it explains several things that were heretofore either contradictory or mysterious. It begins with the assertion that the quarter-mile radius (or 5-minute walk,) which has been held up for a century as the distance Americans will walk before driving, is actually a myth.
