| Abstract | The integration of digital twin (DT) technology within smart city frameworks is becoming increasingly significant in today's digital age. As urban areas evolve into smart ecosystems characterized by interconnected devices and data-driven management systems, digital twins provide a dynamic approach to managing these smart cities. This paper delivers an in-depth exploration of the role of digital twins in advancing smart city frameworks, surveying recent research, methodologies, and case studies that highlight their applicability in urban management, including sectors like mobility, healthcare, energy management, and environmental monitoring. Additionally, the paper delves into the foundational concepts of digital twins and digital twin smart cities, presenting a multilayered structure that emphasizes the role of each layer in creating a comprehensive urban digital twin platform. We also examine the ongoing global digital twin projects based on their development maturity, discuss the challenges of deploying these systems, and explores emerging tools such as synthetic sensing for areas with limited sensor infrastructure. By summarizing the state of the art, identifying research gaps, and discussing future directions, this review serves as a foundational reference for researchers and practitioners seeking to harness digital twin technology for more sustainable, efficient, and resilient smart cities. |
