"This report consists of nine chapters. Chapter 2 describes the effects of technology on transportation in general, the innovative services relevant to this report, what is known about the use of these services, and their potential impacts. Chapter 3 explains the existing regulatory structure of the taxi, sedan, and limousine industries and the challenges to that existing structure presented by the rise of TNCs. Chapter 4 presents an economic framework for address- ing those challenges. Chapters 5 through 8 then review specific issues facing shared mobility services: Chapter 5 examines labor and employment issues; Chapter 6 addresses personal security for drivers and passengers and safety for the public; Chapter 7 reviews insurance issues; and Chapter 8 looks at issues of access and equity. Chapter 9 presents the overall conclusions resulting from this study and the committee’s recommendations for policy makers and regulators who must consider whether and how to regulate these new services to serve public policy goals, and outlines research needs."

In the last ten years transit use in Southern California has fallen significantly. This report investigates that falling transit use. We define Southern California as the six counties that participate in the Southern California Association of Governments (SCAG) – Los Angeles, Orange, Riverside, San Bernardino, Ventura and Imperial. We examine patterns of transit service and patronage over time and across the region, and consider an array of explanations for falling transit use: declining transit service levels, eroding transit service quality, rising fares, falling fuel prices, the growth of Lyft and Uber, the migration of frequent transit users to outlying neighborhoods with less transit service, and rising vehicle ownership. While all of these factors probably play some role, we conclude that the most significant factor is increased motor vehicle access, particularly among low-income households that have traditionally supplied the region with its most frequent and reliable transit users.
