Urban Structure and Sustainability: Chicago and Los Angeles Metro Areas
*Names in bold indicate Presenter
This paper addresses the challenge of defining an integrated method to delimitate metropolitan areas and their internal composition. The methodology developed of the Interaction Value simultaneously allows delimiting these two levels of urban structure: the metropolitan system as a whole and the subsystems articulated around sub centers. At the same time, the IV assesses the degree of polycentrism beyond the simple identification of sub centers developed in the literature. And, so, support the hypothesis that the polycentric city structure is more efficient, from an environmental perspective, than the monocentric. In this sense, and taking the cases of Chicago and Los Angeles MA as examples of different types of urban structure, the efficiency of their metropolitan systems will be evaluated from the dual perspective of land consumption and sustainable mobility.
