Smart Integration of Information Technologies for City Digital Twins

Background: With rising urbanisation and shrinking undeveloped areas, the role of city planning has reached new heights. Incorporating current information technology into city administration provides a path ahead, and the notion of digital twin cities appears as a possible alternative for effective urban planning.Objective: The core objective of this study is to describe the process of constructing city digital twins using modern information technology. Understanding and depicting the transition from essential Building Information Modeling (BIM) to sophisticated City Digital Twins (CDT) is required.Methods: A thorough six-IT-level pyramid is introduced to represent this progression. Beginning with BIM, the model proceeds to incorporate BIM-enabled GIS simulations, Internet of Things (IoT), integration of BIM with Big Data, and Artificial Intelligence, culminating at Level 6 as City Digital Twins. The possibility and technique for developing a CDT information system integrator are also considered.Results: The combination of the IT mentioned above creates comprehensive digital twins for specific buildings and urban areas. This helps with effectively maintaining these buildings and lays the way for the larger goal of smart cities to be realised.Conclusion: The current study highlights the need for a systematic, technology-driven approach to urban planning. The incorporation of sophisticated IT into city planning, namely the notion of City Digital Twins, emerges as a critical instrument in the design and administration of future smart cities.
