“The Science of Cities Is Revolutionizing Urban Planning” by Ramon Gras

What can we learn from Boston’s advanced urban planning?

The understanding of urban planning as a harmonious synthesis of art and science has led to extraordinary theoretical and practical advances over the past decade, particularly by research teams at universities such as Harvard, MIT, and Northeastern, as well as by the most cutting-edge design teams. A deeper understanding of the universal cause-and-effect relationships between urban and architectural morphology and patterns of socialization, design criteria, and access to services, as well as the identification of the ingredients and dynamics that enable the success of economic strategies, has been validated by the analysis of more than 100 global metropolitan areas using 90 analytical indicators. The revolutionary approach of the Science of Cities transforms our understanding of urbanism, reduces uncertainty in decision-making, anticipates problems, overcomes decades of methodological stagnation, and ultimately provides a sound response to global urban challenges with a vision that is in step with the times.

How can the Barcelona metropolitan area benefit from advanced urban planning?

The Barcelona Metropolitan Digital Twin is a software tool that has been under development since 2024, thanks to the support of the Torras Foundation and Barcelona Global, and Aretian’s analysis and design methodology. The Digital Twin enables the development of territorial assessments, the identification of objectives, scenario simulations, and recommendations, and includes five use cases such as addressing the challenge of providing 475,000 quality housing units, identifying urban design criteria for 42,000 vacant lots, guiding the economic strategy for 11 cutting-edge fields of knowledge to drive widespread prosperity, as well as ensuring a sustainable mobility and logistics model.

The metropolitan digital twin has already generated positive social impact in Barcelona, Sant Feliu, Badalona, Esplugues, L’Hospitalet, Viladecans, and Sant Boi. The recent addition of tech giants such as Nvidia and Lenovo to the project allows for the expansion of its potential and the aspiration to become the most sophisticated and cutting-edge model of advanced urban planning in the world, continuing the precious legacy of Cerdà, Jujol, and Gaudí.
