Four EU flagship CitiVerse projects bring the CitiVerse vision into practice through real-world pilots and use cases at Smart City Expo World Congress 2026, 3 to 5 November.
The 3DxVERSE, x-CITE, SENSE and European Citiverses Uniting for Inclusiveness projects, co-funded by the European Union’s Digital Europe Programme, will showcase how the European CitiVerse vision is being put into practice through real-world pilots, use cases and citizen engagement. Coordinated by ERTICO – ITS Europe, 3DxVERSE contributes to this shared European effort by developing AI- and XR-powered digital twins for sustainable mobility and smart urban living.
The four projects come together in one shared CitiVerse booth within the European Twinning & Citiverse Plaza pavilion (Hall 3, Stand D71).
Connecting the physical through the digital
The CitiVerse is an emerging European digital ecosystem where cities can connect, collaborate and co-create solutions to real urban challenges. At its heart are Local Digital Twins: digital representations of cities and urban environments that let citizens, planners, businesses and policymakers explore scenarios, test ideas and support decisions on mobility, climate resilience, public space, accessibility and urban development.
By bringing together artificial intelligence, extended reality, geospatial data and participatory tools, the CitiVerse aims to give cities of every size access to advanced digital capability while strengthening Europe’s digital sovereignty and competitiveness.
Each project has its own focus, and together they contribute to the wider CitiVerse ecosystem:
- 3DxVERSE develops AI- and XR-powered digital twins for sustainable mobility and smart urban living, helping optimise transport, energy use and public services in Aruba, Almelo, Timișoara and Hamburg.
- x-CITE turns complex urban plans and data into interactive 3D experiences, so citizens can explore, understand and help shape their city, with use cases in Flanders, Rotterdam and Tampere.
- SENSE helps cities create interactive, interoperable and real-time digital twins, where citizens and municipalities can jointly explore, test and improve urban spaces. Its pilots run in Cartagena and Kiel, with Arezzo, Valongo, Murcia and Thessaloniki as follower cities.
- European Citiverses Uniting for Inclusiveness explores how Local Digital Twins and AI can support accessibility and inclusiveness, applying Universal Design principles in its Gothenburg pilot.
The four EU flagship CitiVerse projects collaborate to exchange knowledge, align approaches and maximise collective impact. Together, they bring the CitiVerse to life on the ground, testing technologies and approaches in real urban environments, engaging citizens and local stakeholders, and exploring how their results can contribute to interoperable, reusable and scalable solutions across Europe.
3DxVERSE in Barcelona
Alongside the joint sessions, 3DxVERSE will have its own programme at the European Twinning & CitiVerse Plaza pavilion, offering opportunities to discover the project, meet its partners and explore how its digital twin solutions contribute to the European CitiVerse vision. Join our colleagues Ralf Willenbrock, 3DxVERSE project coordinator and Dr Eusebiu Catana, Head of Transport for Logistics, in some of these sessions.
