The accelerated urbanization process in the 21st century has necessitated faster implementation of smart city solutions that deploy digital solutions and promote efficiency, sustainability, and well-being of the population. One of them, the concept of digital twin (DT), has turned out to be a game-changer. A computer simulated physically stimulable and controllable systems or processes A digital twin is the computer simulation of a real-world physical asset. The urban simulation enables DTs to furnish city planners and policymakers with realistically detailed information on how they might maximize resource use, resiliency, and sustainability. The current paper is a systematic review of digital twin technologies in smart cities, specifically, how these technologies can be used in the domains of energy management, transportation, infrastructure monitoring, citizen engagement and public safety. The paper is a review of the academic and business studies, their advantages and disadvantages. Internet of Things (IoT), artificial intelligence (AI), and 5G networks are the technologies that may facilitate the adoption of DTs in the field of predictive maintenance of utilities, traffic optimization, and disaster management. The second interpretation of the results is that the digital twins will enable the adoption of data-driven governance and urban development. Other issues, however, still limit it, including high cost of implementation, interoperability, data privacy, and non-standardized frameworks. The paper develops the case study of the approach strategy of the multidisciplinary approach that presupposes the technical innovation, regulation and collaboration of the separate participants of the procedure in order to get as much as possible out of the potential of DTs. The proposed trends include lightweight and scaled DT forums, artificial intelligence to provide predictive analytic models, solutions to privacy issues and citizen demands are the way to go. Overall, the next-generation digital-twin-based smart cities can support a viable and robust urban ecology that is friendly to humans.
