Digital Twins of Sustainable City

With the constant acceleration of digitization process, Digital Twins technology plays a more and more vital role in the development and construction of Sustainable Cities with some core advanced computer technologies, including Big Data, Artificial Intelligence, Cloud Computing, and Edge Computing. The research is aimed to study the application of Digital Twins in cities and its development prospect based on the construction of Smart Cities. Besides, Digital Twins technology is discussed based on the systematic construction of digitization of urban smart public service facilities. The intelligence of public facilities is investigated in terms of urban public drainage facilities, public lighting systems, and intelligent traffic systems. Finally, the integration of the above facilities with future Digital Twins technology is prospected. By combining communication technology and information technology, the analysis is carried out from the social, economic, and environmental perspectives of sustainable development. This work has reference value for the subsequent intelligent and systematic development of infrastructure of smart city and sustainable city.
