Smart cities leverage technology to improve living conditions through data-driven solutions that enhance infrastructure and services. By integrating Internet of Things (IoT) devices, cities can monitor traffic, energy consumption, and public safety in real-time. This data facilitates efficient resource management, leading to reduced congestion, optimized energy use, and improved waste management. Additionally, smart technologies enable better communication between citizens and local authorities, fostering community engagement. By prioritizing sustainability and resilience, smart cities aim to enhance the quality of life for residents while addressing urban challenges such as pollution and overpopulation.
