The race to make cities sustainable and citizen-focused is accelerating. This episode explores how science and technology can help cities boost their attractivity, resilience, and innovation in the face of growing challenges – environmental, natural disasters, mobility, public health and safety. How do you connect cities ecosystems with new tools and skills such as the 3D virtual twin model and 3DEXPERIENCE platform and help all stakeholders work within a common framework to identify needs, explore potential scenarios, use predictive modelling to plan and execute projects to offer the best quality of life and experience possible for all citizens.
