"Transportation affects how we live, work, and play, but not many books explain how the whole system actually fits together. This is a practical, easy-to-read resource for professionals, students, and anyone who wants to understand how transportation shapes our communities. Honestly, it's the kind of book our industry needs." --Veronica O. Davis, PE, civil engineer and author of Inclusive Transportation "If you have anything to do with designing transportation or cities, this book should be on your desk. When I was a young engineer, I was taught that bigger means better. It doesn't. We'd all be better off if designers understood the geometry of each transportation mode and how those limits shape our cities.

" --Wes Marshall, PhD, PE, professor at the University of Colorado Denver, cohost of the Look Both Ways with David & Wes podcast, and author of Killed by a Traffic Engineer "Distilling the essentials from other noted urbanists, Spieler, Copeland Loredo, and Chapa offer a primer on the role for each mode of transportation and how they work together to make--or damage--great cities. Their main point is critical: functional urban transport is not about ideology but geometry. They help us explore a timeless question: How should we design cities' limited street rights-of-way to best move people and goods and achieve our economic, social, and environmental goals?" --Jeffrey Tumlin, former executive director of the San Francisco Municipal Transportation Agency "Every page of this book is a lesson, conveying important concepts in a clear and visually engaging way. It should be on the desk of any elected official, city leader, professional, student, or community member who wants to make their transportation system work better for people." --Jennifer Dill, Portland State University.
