California is counting on public transit to help meet its ambitious goals to reduce greenhouse gas emissions and traffic congestion. Yet despite large public investments in bus and rail service, the state’s transit ridership is on the decline. ITS scholars are at the forefront of research into mass transit, from its funding and planning to passenger trends to the rider’s safety and experience, informing policymaking aimed at getting more people on board.

Selected Research Publications

A Taste for Transit? Analyzing Public Transit Use Trends Among Youth
Anne E. Brown, Evelyn Blumenberg, Brian D. Taylor, Kelcie Ralph, Carole Turley Voulgaris — 2016
The past decade has seen a decline in driving among youth. Does this portend an increase in public transit ridership? While young adults are more likely to ride transit than older adults, analyzing patterns of youth transit use show that life cycle, demographic, and locational factors suggest that travel behavior established early in life may not necessarily persist as people age.

Does Transit Mean Business? Reconciling Economic, Organizational, and Political Perspectives on Variable Transit Fares
Allison C. Yoh, Brian D. Taylor, John Gahbauer — 2015
Transit fares can vary by mode, distance, and time to reflect the marginal costs of providing transit service, increasing the efficiency and equity of transit service. Recent advances in smartcard fare collection technologies have reduced the operational obstacles to charging variable fares, yet relatively few transit agencies are doing so. Why are transit managers and their governing boards so reluctant to adopt variable fare policies?

Why Do Voters Support Public Transportation? Public Choices and Private Behavior
Michael Manville, Benjamin Cummins — 2014
Support for transportation sales tax elections is often used as a proxy for public support for transit. But many voters who support such taxes do not support increased transit spending, and many people who support transit spending do not support increased sales taxes to finance it. Transit spending is more correlated with belief in its collective rather than private benefits, as most transit spending supporters do not use transit and are unlikely to begin doing so. Can this collective action problem be solved?

Public Transportation Objectives and Rider Demographics: Are Transit’s Priorities Poor Public Policy?
Brian D. Taylor, Eric A. Morris — 2014
Strong public and political support for mass transit in the U.S. is based on lofty goals, including congestion reduction, economic development, aesthetics, sustainability, and much more. Yet the pursuit of multiple and broad objectives, however worthy, can diffuse efforts and fail to achieve desired results. How can policymakers focus on the needs of transit riders themselves, particularly the poor and transit-dependent?
