Introduction: The Pressures on Modern Cities

Cities around the world are facing unprecedented challenges. Climate change is intensifying heatwaves, floods, and other extreme weather events, putting critical infrastructure at risk. Populations are growing, straining transportation, housing, and public services. At the same time, residents expect faster, more responsive, and more personalized services from their local governments. To navigate these combined pressures, cities are turning to data and artificial intelligence (AI) to support better decisions and bolster operations. The promise is significant: by leveraging connected data, AI, edge computing, and computer vision, cities can turn growing volumes of urban data into smarter, faster decisions and more responsive services. This article explores how these technologies are being applied, the challenges that remain, and the insights from leading experts and case studies that are shaping the future of urban innovation.

Harnessing Data and AI for Smarter City Operations

Connected data and AI can fundamentally improve how cities operate. By integrating data from sensors, cameras, traffic systems, utilities, and citizen feedback, cities can gain a holistic view of urban life. AI algorithms can analyze this data in real time to identify patterns, predict problems, and recommend actions. For example, predictive analytics can forecast traffic congestion and optimize signal timing, reducing commute times and emissions. AI can also detect anomalies in water or energy networks, enabling proactive maintenance before failures occur. Beyond operational efficiency, these technologies can enhance citizen engagement. Chatbots and virtual assistants can provide 24/7 information and services, while participatory platforms can gather input on urban planning. Crucially, data and AI can break down departmental silos. When data is shared across agencies, decisions are no longer made in isolation. A transportation department can coordinate with public works and emergency services during a major event, ensuring a unified response. However, achieving this requires robust data governance, interoperability standards, and a culture of collaboration.

The Role of Edge Computing and Computer Vision

Edge computing and computer vision are two technological pillars enabling smarter city operations. Edge computing processes data near the source—such as at a traffic camera or a sensor—rather than sending it to a distant cloud data center. This reduces latency, allowing for real-time decision-making. For instance, an edge-enabled traffic camera can instantly detect an accident and alert emergency services, or adjust signals to reroute traffic. Computer vision, a field of AI that enables machines to interpret visual information, is particularly powerful when combined with edge computing. It can analyze video feeds from thousands of cameras to monitor traffic flow, detect illegal parking, identify safety hazards, or even assess infrastructure damage. In public safety, computer vision can help locate missing persons or detect suspicious behavior, though such applications raise important privacy and ethical considerations. When deployed responsibly, these technologies can make cities more efficient, safe, and sustainable.

Global Summit to Explore Intersection of Climate and Smart Cities

As cities confront the combined pressures of climate change, infrastructure resilience, and digital transformation, a major global smart cities summit in 2026 will bring together urban leaders and partners during London Climate Action Week. The event aims to explore how these agendas intersect—and how cities can translate strategy into practical action. The summit will feature keynote speeches, panel discussions, and workshops on topics such as net-zero urban planning, resilient infrastructure, and AI-driven governance. By convening policymakers, technologists, and community leaders, the summit seeks to accelerate the adoption of solutions that address both climate goals and digital ambitions. London Climate Action Week itself is a key moment for global climate leadership, and the integration of smart city technologies into the climate agenda reflects a growing recognition that digital innovation is essential for achieving sustainability targets.

Malaysia is positioning itself as a leader in AI-powered urban innovation. The first Southeast Asian Smart City Expo in Kuala Lumpur will showcase how Malaysian cities are using AI, IoT, and big data to improve urban services. From smart traffic management in Kuala Lumpur to digital health initiatives in Penang, Malaysia is embracing technology to address rapid urbanization. The expo will bring together startups, multinational corporations, and government agencies to share best practices and forge partnerships. Malaysia’s approach emphasizes inclusive growth, ensuring that smart city benefits reach all citizens, including those in rural areas. The event is expected to attract thousands of visitors and serve as a catalyst for further AI adoption across the region.

Singapore and Sunderland: Case Studies in Smart City Development

Singapore continues to build its reputation as one of the smartest nations in the world. A recent city profile highlights its comprehensive approach to smart city development, including a national digital identity system, smart nation sensors, and AI-powered healthcare. Singapore’s success stems from strong government leadership, investment in research and development, and a focus on citizen-centric services. For example, the city-state uses AI to predict dengue outbreaks, optimize energy consumption in buildings, and manage traffic congestion. Meanwhile, Sunderland in the United Kingdom is repositioning itself as a leading smart city. Using digital infrastructure and low-carbon innovation, Sunderland aims to build a resilient, future-focused economy. The city has deployed smart sensors to monitor air quality, invested in electric vehicle charging networks, and created a digital twin to simulate urban development scenarios. Both Singapore and Sunderland demonstrate that smart city transformation is not limited to megacities; mid-sized cities can also leverage technology to improve quality of life and drive economic growth.

Expert Insights: AI Moving from Pilots to Real-World Impact

Professor Jung Hoon Lee, a leading expert on smart cities, recently discussed how AI is moving from pilots to real-world impact in cities worldwide. In a podcast interview, he talked about the latest Global Smart City Index, the emerging “AI super gap” between cities, and why the next phase of urban innovation depends on data platforms, AI-ready infrastructure, and effective governance. The AI super gap refers to the widening disparity between cities that have successfully integrated AI into their operations and those that are still experimenting. Professor Lee argues that without robust data platforms—which enable data sharing and interoperability—cities will struggle to scale AI solutions. AI-ready infrastructure, including edge computing and 5G connectivity, is also essential. Finally, effective governance is needed to address ethical, privacy, and security concerns. Professor Lee’s insights underscore that technology alone is not enough; cities must also invest in human capital, policy frameworks, and public trust.

Improving Indoor Safety with Smart Sensor Networks

Smart sensor networks are increasingly used to improve indoor safety. By detecting risks early, such as smoke, gas leaks, or structural anomalies, these networks can prevent accidents and save lives. They also improve situational awareness for building managers and first responders, allowing for faster evacuation or targeted intervention. Beyond safety, smart sensors contribute to healthier, more secure, and sustainable buildings. For instance, they can monitor air quality, temperature, and humidity, adjusting ventilation systems to optimize comfort and energy efficiency. In the wake of the COVID-19 pandemic, demand for such technologies has surged, as building owners seek to assure occupants of safe indoor environments. As sensor costs decline and connectivity improves, adoption is expected to grow rapidly in offices, schools, hospitals, and homes.

Urban AI Applications: Evolution and Impact

Gareth Tang, President of Urban Solutions at ST Engineering, explains how urban AI applications are set to evolve. In an interview, he detailed projects where AI is already making significant impact.
