AI as a Game-Changer for Urban Living
The study emphasizes AI’s potential to transform cities into smarter, more efficient, and sustainable places. As urban populations grow—projected to reach 5.2 billion by 2030—cities face issues like traffic jams, air pollution, and resource strain. AI offers solutions by enabling cities to manage services autonomously. For example, AI can optimize traffic flow, monitor air quality in real-time, and reduce energy waste in buildings. These advancements aim to improve residents’ quality of life while tackling environmental challenges, such as the fact that cities contribute 60-80% of global greenhouse gas emissions.
The researchers highlight AI’s role in areas like smart transportation, where it predicts traffic patterns, and environmental monitoring, where it tracks pollution sources using sensors. AI also powers energy-efficient buildings and supports urban planning by simulating how city layouts affect air quality. However, the study notes challenges, including privacy concerns and ethical issues, such as ensuring AI systems do not discriminate in service delivery.

A Surge in AI-Smart City Research
The study conducted a bibliometric analysis, examining 4,719 research papers from 2006 to 2024, sourced from the Scopus database. This analysis reveals a sharp rise in interest, with publications increasing from just a few per year before 2017 to 1,105 in 2023 alone. This growth reflects global recognition of AI’s importance in urban development. The research spans disciplines, with computer science leading at 33%, followed by engineering (22%) and mathematics (8%). Social sciences and environmental studies also contribute, showing AI’s broad impact.
Key institutions driving this research include King Saud University (Saudi Arabia) with 64 publications, followed by other Saudi and Indian universities. China’s National Natural Science Foundation funded 313 studies, underscoring the country’s investment in AI. Journals like IEEE Access and Sensors are major outlets, publishing work on AI’s integration with technologies like the Internet of Things (IoT).

Global Contributions and Collaboration
India leads with 1,055 research articles, followed by China and Saudi Arabia, reflecting significant investments in AI for urban innovation. The study notes strong international collaboration, with countries like the U.S. and EU members funding projects through programs like Horizon 2020. This global effort highlights the shared goal of using AI to create sustainable cities.
The researchers propose a future research agenda, urging studies on AI’s ethical implications, such as ensuring fairness in automated systems. They also call for integrating AI with technologies like 5G and drones for advanced urban solutions. Addressing regulatory concerns, like data privacy, is another priority to ensure AI’s benefits are equitable.
