CityNexus is an innovative urban digital twin application designed to assess the environmental, social, and economic impacts of changes in road networks, mobility, and urban space design.

The platform is designed to respond to the needs of the Local Council of Amager Vest, a district of the city of Copenhagen, primary end-user of the project, providing policymakers a collaborative platform to experiment with various strategies and solutions, considering diverse factors and variables crucial for successful and sustainable urban interventions, thereby facilitating a coordinated approach to decision-making.

The CityNexus platform aims to facilitate evidence-based decision-making at the municipality level by providing capabilities to evaluate a comprehensive set of Key Performance Indicators (KPIs) and by implementing an interactive system for assessing the impact of infrastructural and mobility changes on the target KPIs through policy-relevant, user-defined ‘what-if’ scenario simulations.
