DTs are often composed by several interconnected models, which need to be specifically tailored to fit the DT purposes. The objective of this work is the development of an urban digital twin (UDT) for the city of Matera, following urban intelligence (UI) paradigm. The latter leverages the multi-disciplinary integration and optimization of the city systems and subsystems to develop purpose-driven DTs and support the decision-making process. The UDT is intended to support governance, stakeholders, and citizens, integrating morphological data for the city representation, reliable simulation tools and data-driven methods for the city state prediction (e.g., traffic, solar irradiation), optimization algorithms for planning and emergency response, sensors for vehicle and pedestrian traffic volumes and environmental monitoring (e.g., pollutant distributions), and a participatory data collection process from the citizens. A Data Lake is used to make available to the UDT modules the data produced by the morphological representation, simulations\/data-driven methods, sensors, and the participatory data. The Data Lake provides a standardized approach for the aggregation and extraction of information. Finally, an Urban Sensing Engine supports the decision-making process with artificial intelligence forms of reasoning, to effectively combine the information produced by the UDT components.<\/jats:p>","DOI":"10.1007\/s40860-025-00245-3","type":"journal-article","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T13:58:47Z","timestamp":1740146327000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Digital twins for intelligent cities: the case study of Matera"],"prefix":"10.1007","volume":"11","author":[{"given":"Riccardo","family":"De Benedictis","sequence":"first","affiliation":[]},{"given":"Amedeo","family":"Cesta","sequence":"additional","affiliation":[]},{"given":"Riccardo","family":"Pellegrini","sequence":"additional","affiliation":[]},{"given":"Matteo","family":"Diez","sequence":"additional","affiliation":[]},{"given":"Diego Maria","family":"Pinto","sequence":"additional","affiliation":[]},{"given":"Paolo","family":"Ventura","sequence":"additional","affiliation":[]},{"given":"Giuseppe","family":"Stecca","sequence":"additional","affiliation":[]},{"given":"Giovanni","family":"Felici","sequence":"additional","affiliation":[]},{"given":"Andreas","family":"Scalas","sequence":"additional","affiliation":[]},{"given":"Michela","family":"Mortara","sequence":"additional","affiliation":[]},{"given":"Daniela","family":"Cabiddu","sequence":"additional","affiliation":[]},{"given":"Simone","family":"Pittaluga","sequence":"additional","affiliation":[]},{"given":"Michela","family":"Spagnuolo","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9890-8409","authenticated-orcid":false,"given":"Stefano","family":"Silvestri","sequence":"additional","affiliation":[]},{"given":"Emanuele","family":"Damiano","sequence":"additional","affiliation":[]},{"given":"Mario","family":"Sicuranza","sequence":"additional","affiliation":[]},{"given":"Mario","family":"Ciampi","sequence":"additional","affiliation":[]},{"given":"Gabriella","family":"Tognola","sequence":"additional","affiliation":[]},{"given":"Lucanos","family":"Strambini","sequence":"additional","affiliation":[]},{"given":"Roberto","family":"Malvezzi","sequence":"additional","affiliation":[]},{"given":"Ida G.","family":"Presta","sequence":"additional","affiliation":[]},{"given":"Marialucia","family":"Camardelli","sequence":"additional","affiliation":[]},{"given":"Giordana","family":"Castelli","sequence":"additional","affiliation":[]},{"given":"Emilio Fortunato","family":"Campana","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2025,2,21]]},"reference":[{"key":"245_CR1","doi-asserted-by":"publisher","first-page":"86448","DOI":"10.1109\/ACCESS.2020.2992441","volume":"8","author":"A Kirimtat","year":"2020","unstructured":"Kirimtat A, Krejcar O, Kertesz A, Tasgetiren MF (2020) Future trends and current state of smart city concepts: a survey.
