Samuel Speroni

Sam Speroni is a doctoral student in the UCLA Department of Urban Planning and a researcher with the UCLA Institute of Transportation Studies and UCLA Lewis Center for Regional Policy Studies.  He completed his master’s degree in Urban and Regional Planning, also at UCLA, in June 2020.  Sam is advised by Dr. Evelyn Blumenberg and Dr. Brian D. Taylor.

Sam’s primary research interest lies at the intersection of transportation, education, and new mobility, where he looks for ways to improve equitable access to educational opportunities for vulnerable and disadvantaged student populations.  His research extends to many other aspects of travel behavior and transportation systems, all with an emphasis on equity.  Sam’s recent applied planning research project analyzing high school students’ ridehail trips to school for HopSkipDrive (full report | policy brief) received the national Neville A. Parker Award for outstanding master’s capstone in transportation policy and planning from the Council of University Transportation Centers (CUTC).

Sam is a Future Leaders Development fellow of the Eno Center for Transportation in Washington, D.C., and in 2020 he was named the Pacific Southwest Region University Transportation Center (PSR UTC) outstanding student of the year.  He is also the recipient of the Dwight D. Eisenhower Transportation Graduate Fellowship (2019 and 2020) and the Intelligent Transportation Systems California / California Transportation Foundation joint graduate scholarship (2020).

Prior to UCLA, Sam was a high school English teacher and school administrator in Charlotte, North Carolina, through Teach for America.  Originally from New England, Sam grew up in Massachusetts and earned his bachelor’s degree in Urban Studies with honors from Brown University in 2011, where he was also captain of the varsity swimming & diving team.

Brian D. Taylor

Brian Taylor is Professor of Urban Planning and Public Policy, and Director of the Institute of Transportation Studies at UCLA.

Professor Taylor’s research centers on transportation policy and planning – most of it conducted in close collaboration with his many exceptional students. His students have won dozens of national awards for their work, and today hold positions at the highest levels of planning analysis, teaching, and practice.

Professor Taylor explores how society pays for transportation systems and how these systems in turn serve the needs of people who – because of low income, disability, location, or age – have lower levels of mobility. Topically, his research examines travel behavior, transportation economics & finance, and politics & planning.

His research on travel behavior has examined (1) the social, economic, and spatial factors explaining public transit use, (2) ways to cost-effectively increase public transit use, (3) how and why travel patterns vary by race/ethnicity, sex, age, and income, (4) the emerging travel patterns teens and young adults, (5) gender divisions of household labor and travel, (6) the effect of travel experience on how people perceive opportunities, (7) the role of walking, waiting, and transferring on travel choices, and (8) the equity implications of new shared mobility systems.

A principal focus of his research is the politics of transportation economics & finance, including (1) alternative ways to evaluate the access and economic effects of traffic congestion on people, firms, and regional economies, (2) the history of freeway planning and finance, (3) emerging trends in pricing road use, (4) the equity of alternative forms of transportation pricing and finance, (5) linking of subsidies to public transit performance, and (6) measuring equity in public transit pricing and finance.

The politics of planning practice inform Professor Taylor’s teaching, which regularly includes courses on Transportation and Land Use: Urban Form, Public Transit and Shared Mobility, Transportation Economics, Finance, and Policy, courses in research design for planners, and, occasionally, the Comparative International Transportation Workshop. Prior to joining the UCLA faculty, Professor Taylor was a planning faculty member at the University of North Carolina at Chapel Hill, and before that he was a planner with the Metropolitan Transportation Commission in the San Francisco Bay Area.
