Transport Truths

Planning Methods and Ethics for Global Futures

Ideal for researchers and practitioners looking for fresh approaches to transport problems, this book combines cutting-edge qualitative and qualitative knowledge to inform transport futures. It uses engaging case studies of the Banjul Airport Expansion in The Gambia, and the Interstate 35 development project in Austin, US to show how and why a transdisciplinary approach can result in better planning decisions.

As cities grow, shrink and re-organize, with access provided by transport infrastructure, this book demonstrates the value of critical realism to create lasting, positive impacts on society and the environment.

  • "This book offers a crucial perspective for transport professionals who are increasingly called upon to make ‘data-driven’ or ‘evidence-based’ recommendations. Greg Griffin invites us to consider the full variety of sources of and uses for knowledge that can guide action towards more just and sustainable transport systems."

  • “This book shines a light on upstream approaches to transportation project challenges—which can perpetuate the ‘solutions’ that not only never quite work, but often make the problems worse.”

    Marc Schlossberg, University of Oregon

  • "Using engaging case studies, Transport Truths reveals that transportation solutions will not come solely through data and modeling and offers researchers and practitioners a more holistic approach better fitting today’s complex world."
