For the first time in half a century, real transformative innovations are coming to our world of passenger transportation. The convergence of new shared mobility services with automated and electric vehicles promises to significantly reshape our lives and communities for the better—or for the worse.

The dream scenario could bring huge public and private benefits, including more transportation choices, greater affordability and accessibility, and healthier, more livable cities, along with reduced greenhouse gas emissions. The nightmare scenario could bring more urban sprawl, energy use, greenhouse gas emissions, and unhealthy cities and individuals.

In Three Revolutions, transportation expert Dan Sperling, along with seven other leaders in the field, share research?based insights on potential public benefits and impacts of the three transportation revolutions. They describe innovative ideas and partnerships, and explore the role government policy can play in steering the new transportation paradigm toward the public interest—toward our dream scenario of social equity, environmental sustainability, and urban livability.

Many factors will influence these revolutions—including the willingness of travelers to share rides and eschew car ownership; continuing reductions in battery, fuel cell, and automation costs; and the adaptiveness of companies. But one of the most important factors is policy.

Three Revolutions offers policy recommendations and provides insight and knowledge that could lead to wiser choices by all. With this book, Sperling and his collaborators hope to steer these revolutions toward the public interest and a better quality of life for everyone.

Dr. Daniel Sperling is Professor of Civil Engineering and Environmental Science and Policy, and founding Director of the Institute of Transportation Studies at the University of California, Davis (ITS-Davis). The Institute has over 150 faculty, staff and student researchers.

He has led ITS-Davis to international prominence by building strong partnerships with industry, government, and the environmental community, integrating interdisciplinary research and education programs, and connecting research with public outreach and education.

In June 2013, he was named a recipient of the Blue Planet Prize from the Asahi Glass Foundation. The prize has been described as the Nobel Prize for the environmental sciences. He was recognized for his unique ability to bring together the top thinkers and strategists in academia, government and industry to develop new vehicle- and fuels-policy approaches that are models for the world.

In February 2007, Governor Schwarzenegger appointed him to the “automotive engineering” seat on the California Air Resources Board. His appointment was confirmed by the California Senate in January 2008. His chief responsibilities are oversight and design of the state’s climate change, alternatives fuels, vehicle travel and land use, and zero emission vehicle programs. He also served as co-director of the California Low Carbon Fuel Standard study, requested in the Governor’s January 2007 Executive Order. In 2008 he was appointed chair of the “Future of Mobility” Council of the Davos World Economic Forum.

Dr. Sperling is recognized as a leading international expert on transportation technology assessment, energy and environmental aspects of transportation, and transportation policy. He has testified 10 times to the US Congress and state legislatures, and provided keynote presentations and invited talks in recent years at international conferences in Asia, Europe, and North America. In the past 25 years, he has authored or co-authored over 200 technical papers and 11 books, including Two Billion Cars (Oxford University Press, 2009). He has made 500 professional presentations in his career, including many keynote talks in the past few years.

Sperling is an international expert on transportation technology, fuels and policy, with a focus on energy and environment. His research is directed at accelerating the global transition to cleaner, more efficient transportation and energy, and mitigating climate change. The award recognizes Sperling for his unique ability to bring together the top thinkers and strategists in academia, government and industry to develop new vehicle- and fuels-policy approaches that are models for the world.
