Transportation infrastructures are indispensable for urban life. For instance, without mobility infrastructures, individuals would not be able to reach jobs and access food, education and healthcare. Similarly, without stable and efficient systems for transporting people and goods, firms would not have access to the materials, workers and customers they require to be successful. But transportation networks also have other impacts: they make social life possible, they are spaces for cultural exchange, and are sites and objects of political struggle. In this course we will study urban mobility from a multidisciplinary perspective and analyze transportation infrastructures as complex socio-technical systems focusing on three key questions: 1) How do mobility systems impact economic, social and environmental dimensions of urban life? 2) What are the politics behind transportation planning decisions? and 3) How can transportation infrastructures help produce more inclusive cities? The course draws from classic transportation planning and policy literature as well as new and critical scholarship on urban mobility and urban politics from a variety of disciplines, including geography, sociology, anthropology and urban planning. This is a seminar plus course that will include field trips and guest presentations by transportation experts. Assignments will include individual and group research focused on transportation projects and policies in the US and across the globe.
