T-Twin

T-Twin develops a next-generation Digital Twin platform to modernise Sweden’s traffic management. Building on the GEMINI pilot in Kista, the project integrates real-time data, simulation and AI to move beyond today’s local and reactive control systems. By testing coordinated motorway and urban strategies - such as dynamic speed limits and adaptive signal control - on the Södra länken corridor, T-Twin aims to create a scalable DT Sandbox that supports safer, more efficient, and more proactive traffic operations.
