His work focuses on the social contexts of urban transportation systems, explored in three ways: 1. the effects on social equity of current transportation planning practices – how people participate in planning, and who wins and loses from transportation plans, 2. planning, research and advocacy in support of alternatives to the automobile (especially public transportation and bicycles), and 3. the historical roots of automobile dependence in the United States. At PSU, Dr. Golub teaches courses on urban transportation policy, planning research methods, transportation finance and public transportation.
