Making cities walkable again

Walkable cities are marvelous creations. They give us freedom from cars, freedom from sprawl, and freedom to walk our cities, as urban planner Jeff Speck says. Speck gave a TED Talk where he explained four planning principles to transform sprawling cities “into safe, walkable oases full of bike lanes and tree-lined streets.” His main point is that if you want to have a walkable city you can’t start with the sprawl model, you need the bones of an urban model and then build on it (runtime 18:37).
