A digital twin is a digital replica or representation of a system, process or place which mimics its real-world behaviour. OR It’s a real-time updated collection of data, models and algorithms allowing for better real-time analysis of assets.

1. Create a cloud and HPC enabled Digital Twin approach for collaborative policy making 2. Test Digital Twin approach for more effective policy experimentation 3. Ensure wider sustainability and impact through the scalability and transferability of outcomes

1. Brings all the different datasources & assets of the city together in one digital replica of the city. 2. Predictive functionalities of the digital twins. 3. Governance will be able to make decisions based on cross-domain simulations. All data available in a city can be used as an input for models to support governance in simulating different scenarios for urban planning.

In Athens, Greece - The digital twin of DUET will create an interactive pool of data included in the digital replica of Athens. This will be dynamically updated, open, robust and usable for evidence-based decision making. DAEM pilot will launch the Athens digital twin in order to facilitate the exploration and experimentation targetting polution reduction and city planning with the final goal to explore solutions and decision that can boost the quality of life in Athens. Flanders region, Belgium - The DUET digital twin will help the region to provide a better view on the interactions in between evolutions in the city and on the effect of decisions over multiple policy domains (eg. mobility, environment, spatial planning etc.). Moreover the digital twin can help developing cities and communities as a smartcity Governments - digital twins can be used for evidence based decision making. It will be easy to take decisions based on what is going on in the city rather than data of a few years. Forecasts in the impact of the decision and being able to simulate different scenarios is one of the key benefits of using digital twins for governance.
