Virtuocity is a unique programme for city simulation and co-design. It provides an immersive, “human in the loop”, simulation and visualisation facility – “powered” by academic models and industry software, and delivered by an interdisciplinary team of academics with decades of expertise between them. Virtuocity provides a world-leading technical platform and leverages research and innovation expertise from across the University of Leeds (including the Institute for Transport Studies – itself an internationally-recognised centre for transport research). Virtuocity also links to a wide range of external partners and stakeholders – making Leeds a world player in simulation and virtual prototyping of solutions to future challenges in urban mobility and urban dynamics.
