Research and application of digital twin technology in smart city

Digital twin is a forward-looking notion in digital governance and the development direction of smart cities. Digital twin technology, as a novel technological means, offers favorable support for decision-making and prediction in smart city construction by simulating real-world information. This paper commences from the concept formation of digital twin smart cities, elaborates on the research and application of its technology based on practical practices, and provides application strategies in traffic management, energy systems, environmental protection detection, and public safety. This approach can achieve real-time monitoring and optimization of urban operational status, promote intelligent and efficient urban management, and offer a new concept for the development and construction of smart cities.
