Below is a complete bibliography of the 150+ source documents that provided much of the raw material for the four scenarios of mobility in U.S. metro areas in 2030. Over the last year, our research team has conducted a comprehensive horizon scan of current debate over the nature and impact of new technological innovations. These documents include research articles, case studies, news reports, and opinions and essays – produced by transportation experts, technology experts, journalists, and amateur observers.  From these source materials we have identified many more new technologies, new scientific discoveries, forecasts and speculation, and emerging conflicts. Some of these documents helped us identify patterns in the emerging discourse and speculation around trends in transportation, others provided expert insights and recent research findings with major impacts for future cities.
