Addresses the study of human behavior as a central concern in the design of parks and other public spaces. It turns the act of people-watching into a tool for gathering design-relevant data for playgrounds, campgrounds, neighborhood parks, sitting spaces, urban plazas and teen hangouts, without the need for complicated instruments, highly trained personnel, or big budgets. The findings of behaviorists are translated into practical design steps and highlights common design errors, using hundreds of illustrations and actual examples of behavior-oriented techniques.
