In essence, the research aims to answer the question, \"What role does a city's built environment play, if any, in the sustainability of its mobility system?\" To answer this question, I first derive an operational definition of sustainable mobility: maintaining the capability to provide non-declining accessibility in time. Providing non-declining accessibility depends on our ability to maintain net capital (natural, human-made, social) stocks, or, at least, the capability of these stocks to provide current levels of accessibility to future generations. In other words, we can think of a more sustainable mobility system as one that provides more welfare per unit of throughput, with welfare measured by accessibility and throughput measured by mobility. This is a normative framework. It can only indicate relative levels of sustainable mobility. Within a specific city, this framework can allow us to measure which parts of the city produce more sustainable mobility patterns. To employ this framework, I utilize a utility-derived accessibility measure.","abstract_html":"This dissertation examines the concept of sustainable mobility within an urban context.
