CITYNEXUS is an urban digital twin platform that supports municipalities in evidence-based decision-making for mobility, environmental quality, and resilience. It integrates high-resolution geospatial data, machine learning, and modeling frameworks to create a virtual laboratory where stakeholders can test and compare interventions in a risk-free environment, reducing uncertainty and supporting robust urban planning.

CITYNEXUS PRO integrates now new data sources, enhancing simulation and visualization, and improving scalability. New key features include differential NO₂ modeling, flood-aware mobility analysis, and interactive scenario definition. These upgrades expand its applicability from traffic and air quality management to flood resilience and broader urban planning challenges.
