"""To read Human Transit, Revised Edition is to grasp not just what makes an effective bus route or rail line, but to also understand the geometry, economics, and human values that shape cities--and that enhance or diminish them. How we respond to the vital questions in this book will help us address the urgent climate, safety, health, economic, equity, and mobility challenges that cities face.""--Janette Sadik-Khan, Principal, Bloomberg Associates, Former Commissioner, NYC Dept. of Transportation"
