Decide better.

DUET Digital Twins provide virtual city replicas which make it easy to understand the complex interrelation between traffic, air quality, noise and other urban factors. Powerful analytics model the expected impacts of potential change to help you make better evidence-based operational decisions and longer term policy choices.

What is a Digital Twin?

A Digital Twin is a new concept consisting of a continuously learning digital copy of real-world assets, systems and processes that can be queried for specific outcomes.


DUETs Digital Twins consume open data and data models from different sources within the city and integrate them with new technology capabilities including High Powered Computing (HPC), Artificial Intelligence (AI) and Advanced Analytics  to provide a replica city environment where policy experimentation can safely take place.


By predicting asset behaviour and capacity to deliver on specific outcomes within given parameters and cost constraints, the Digital Twin provides a risk-free experimentation environment to inform policy makers and operations managers what they need to do with the assets in the real-word in order to both achieve the most effective long-term policy outcomes, and short-term operational decisions.

Benefits of a Public Sector Digital Twin

Secure Icon - Blue

Improved Operations

Make service decisions based on a unified view of city processes with real-time information and predictive impact simulations

Yellow 3D Euro Sign

Increased Value for Money

Experiment with different policy options online, exploring impacts across multiple domains, rather than running multiple costly on-the-ground pilots


Better Citizen Experience

Act quickly and seamlessly on citizen real-time needs and help people understand why certain planning or operational decisions have been made

Meet DUET at Upcoming Events

  • 29 Jun, 09:30 – 01 Jul, 16:30
    Groningen, Groningen, Netherlands
    The 9th Living Knowledge Conference aims to bring together all those involved in doing or supporting research with and for communities. What can we learn from each other’s approaches? How can we collaborate? Which links have been forged and which could we still make?
  • 29 Jun, 12:00 CEST
    In this webinar, Gert Vervaet, co-coordinator DUET project, and Thomas Adolphi, of VCS, offer a recap of the DUET project as well as an outlook on what lies ahead. An open discussion session will round off the webinar.
  • 02 Nov, 09:00 GMT – 04 Nov, 17:00 GMT
    Larissa, Larissa, Greece
    Opportunity to share latest government innovations and experiences in an open and friendly atmosphere. The annual conference, workshops, webinars and social networks are key enablers for collective growth.


"From air and noise pollution to traffic congestion and physical inactivity, our urban areas and the people living within them are facing a lot of challenges. Designing and agreeing upon solutions to these challenges is difficult. But, the DUET digital twins and COMPAIR projects are offering a cool new way to visualise and explore potential solutions quickly and effectively. Beyond visualisation, these projects are also offering a way for a range of people to work together to make more informed choices about what works best for them and their local areas."
