Understanding how individuals define their walking environment is key to measure the role played by the built environment in (dis)encouraging walking and other active transport modes. This presentation discusses how walkability has been traditionally studied in the scientific literature and proposes a model for the "Perceived Walking Neighborhood". The model is estimated over data from Santiago, Chile. Results show how socioeconomic characteristics and land use attributes influence the shape of the walking neighborhood, opening the possibility to estimate individual-specific accessibility curves. Further research in this subject, such as the inclusion of factors accounting for residential self-selection and spatial dependency, is proposed and discussed.
Ricardo Hurtubia is Assistant Professor at Pontificia Universidad Cat�lica de Chile, with a dual appointment to the School of Architecture and the Department of Transport Engineering and Logistics. He is Associate Researcher at the Centre for Sustainable Urban Development (CEDEUS) and Invited Researcher at the Complex Engineering Systems Institute (ISCI). He completed his PhD at EPFL (Mathematics) in 2012, under the supervision of Professor Michel Bierlaire. His research is focused on location choice models, integrated transport and land use models, accessibility indicators as tools for project and policy evaluation and the use of discrete choice models to analyze and improve the design of public spaces and infrastructure through the understanding of user behavior.
