Is Barcelona a 15-minute city?

Digital twins are virtual representations used to test an object or physical process. This advanced practice has been used to check whether Barcelona fulfils the provision of services or facilities in the model for so-called ‘15-minute cities’, through a website platform to analyse the accessibility of public facilities. This is the first result of collaboration with the Barcelona Supercomputing Center- Centro Nacional de Supercomputación (BSC-CNS).

The site allows users to check things such as metro stops within a 10-minute walk before and after the future L8 and L9 lines open, electric charging points, Bicing stations, health facilities, the distribution of green spaces in the city and more.

This is the first stage of a project developed by specialists at the BSC with the collaboration of the Municipal IT Institute (IMI) and Barcelona Regional (BR) as the main expert using the digital twin. It has allowed for simulations of various types of use to make forecasts, test the effects of the application for certain projects and the potential impact for certain public policies.

There are plans to develop a more complex and more robust digital twin project with more interrelated data, moving more reliably towards solutions and decisions that improve people’s lives and which can be used by any city interested in the future.

This second stage, which could produce a first version which operates with some systems in a time frame of 2 to 4 years, comes through collaboration with Bologna (BSC, CINECA Interuniversity Consortium and the University of bologna). This collaboration will develop a new model for evidence-based public policies based on the construction and development of urban digital twins, the goal being to improve public policies in both cities.
