Smart technologies significantly impact city infrastructure by enabling data-driven solutions that enhance urban living. They facilitate the integration of IoT devices for efficient resource management, transport optimization, and energy conservation. For example, smart traffic systems can reduce congestion by analyzing real-time data, while energy-efficient grids can adjust power distribution based on demand. This proactive approach to urban management leads to sustainable development, improved quality of life, and increased operational efficiency throughout the city, making it more resilient against challenges.
