タイトル：Revisiting the N-Minute City: Big Data Evidence from New York City and Singapore
概要：The concept of the N-minute city—centered on neighborhood self-sufficiency—has gained prominence in urban planning, particularly in response to the COVID-19 pandemic, which has encouraged shorter-distance travel and greater adoption of remote work. This talk revisits ongoing debates on the N-minute city by addressing two key questions: (1) Can N-minute city indices be more effectively constructed using a dynamic choice framework that captures spatiotemporal variations in residents’ preferences for amenities and locations—by incorporating the geographic distribution of amenities with varying quality levels and travel costs weighted by resident attributes—rather than relying solely on the density of predefined points of interest (POIs)? (2) Do planning parameters such as the balance between commercial and residential land use serve as more meaningful indicators for assessing the potential realization of N-minute city ideals in planning practice than POI density alone? Drawing on big data from mobile phone-based mobility patterns in New York City and subway ridership in Singapore, this talk offers new insights into more robust ways of measuring and applying N-minute city principles across diverse metropolitan contexts.
