Moreover, in the digital age, untapped potential exists for using disruptive technologies in urban planning to enhance evidence-based decision-making. This study explored the promotion of age-friendly environments through the transformative potential of Local Digital Twins (LDTs) by integrating geographic information system (GIS) data, data analytics, and artificial intelligence. Tested in the European Commission-funded URBANAGE project, this study presents a digital twin-based Long-Term Urban Planner tool with simulation capabilities that allow for a comprehensive analysis and modelling of the effects of urban interventions. Two use cases are showcased: one suggesting public space intervention and the other tackling future demographic trends. The main contribution of this study is the definition and development of an LDT using a modular-component-based approach that facilitates reuse and adaptation. Unlike isolated approaches, it provides a holistic solution that integrates social and technological domains. This study advances the understanding of the use of LDTs to create inclusive neighbourhoods by assessing neighbourhood age-friendliness and proposing informed urban interventions while underscoring the importance of robust data governance and capacity building among civil servants.eng© 2024 The AuthorsAge-friendly citiesArtificial intelligenceGISLocal Digital TwinSmart citiesUrban planningjournal article2025-03-03
