摘要
Many countries and governments consider smart cities a solution to global warming,population growth,and resource depletion.Numerous challenges arise while creating a smart city.Digital twins,along with the Internet of Things,fifth-generation wireless systems,blockchain,collaborative computing,simulation,and artificial intelligence technologies,offer great potential in the transformation of the current urban governance paradigm toward smart cities.In this paper,the concept of a digital twin city(DTC)is proposed.The characteristics,key technologies,and application scenarios of a DTC are elaborated upon.Further,we discuss the theories,research directions,and framework regarding DTCs.
