Measuring Urban Form and Its Effects on Urban Vitality in Seoul, South Korea: Urban Morphometric Approach

초록

Urban vitality is a core feature of sustainable cities and neighborhoods. Acknowledging the significant role of the spatial and physical attributes of built urban landscapes in influencing urban vitality, scholars and planners in the field of urban studies have meticulously examined the relationship between urban morphology and variations in urban vitality. While most previous studies have primarily focused on a narrow range of factors when analyzing urban form, often neglecting its multifaceted nature, this study utilizes urban morphometrics using Python's Momepy library to offer a comprehensive typology. It integrates diverse urban components from individual buildings and streets to entire neighborhoods into a unified, holistic framework, providing a more integrated understanding of urban form's influence on urban vitality. Our spatial econometric models identified higher building floor areas, taller and narrower streetside buildings, diversely aged buildings, and higher building coverings on lots as favorable urban form settings for urban vitality. Measuring urban morphology with advanced methods and identifying their relationship to urban vitality provides insightful implications for urban planners and designers for creating vibrant cities and neighborhoods. © 2024 American Society of Civil Engineers.
