Modern Chinese cities, which have developed at a rapid speed and on a massive scale for about thirty years, are confronted with many challenges to becoming more livable, healthy and sustainable. Among a variety of design principles this book suggests that walkability is the fundamental principle to improving quality of life. A walkable city provides a convenient and comfortable walking and cycling environment for all local residents. This book attempts to explore the design innovation of creating a walkable city and to propose solutions within the high-density cities Shenzhen and Shanghai. Selected cases include an urban village in Shenzhen and the CBD and a workers' community in Shanghai as different spatial examples to which to apply specific design strategies for a livable, healthy and sustainable city.
