This paper explores the utilisation of knowledge graphs to enhance urban resilience and accessibility in city planning. We expand The World Avatar (TWA) dynamic knowledge graph to support comprehensive decision-making in disaster response and urban planning. By employing an agent-based implementation approach and integrating diverse data sources—including flood data, geospatial building information, land plots, and open-source data—through sets of ontologies, we demonstrate disaster response in a coastal town in the UK and various aspects relevant to city planning for a mid-sized town in Germany using TWA. In King’s Lynn, our agent-based approach facilitates holistic disaster response by calculating optimal routes, avoiding flooded segments dynamically, assessing infrastructure accessibility before and during a flood, identifying inaccessible population areas, guiding infrastructure restoration, and conducting critical path analysis. In Pirmasens, for city planning purposes, the knowledge graph-driven isochrone generation provides evidence-based insights into current amenity coverage and enables scenario planning for future amenities while adhering to land regulations. Additionally, it facilitates cross-domain correlation analysis and provides demographic insights through the representation of building information, isochrones, and population density using ontologies.
