Is your city designed for cars or for people? Jan Gehl has spent his career trying to convince cities to think on the scale of human experience: not only creating physically safe spaces for people to bike, walk, and sit, but also making those places inviting. In his classic book Cities for People, he offers the wisdom of forty years spent revolutionizing urban planning, including a toolbox of practical reference material.
