Abstract

Smart cities, driven by Artificial Intelligence (AI), are transforming urban living by enhancing efficiency, sustainability, and human well-being. This review explores the integration of AI in six key smart city domains: governance, economy, mobility, environment, living, and people. AI enables real-time decision-making, predictive analytics, and improved public services through interconnected digital systems. Drawing on scholarly research from the past two decades, the paper examines AI’s role in optimizing urban infrastructure and addressing socio-environmental challenges. Case studies from different regions are also reported, demonstrating practical applications of AI in shaping sustainable urban development. It highlights the potential of AI to promote inclusive and resilient cities, while also addressing ethical, infrastructural, and policy-related challenges essential for sustainable urban development.
