Smart Cities refer to urban areas that leverage digital technology, data analytics, and interconnected devices to enhance the quality of life for their citizens and improve the efficiency of urban services. These cities use a variety of technologies like Internet of Things (IoT) sensors, artificial intelligence, and big data analytics to collect and analyze data from various sources such as traffic lights, waste management systems, and water supply networks. This data is then used to optimize resources, plan preventive maintenance activities, and address real-time challenges like traffic congestion and energy consumption. By integrating the physical, digital, and human systems in built environments, smart cities aim to create more sustainable and resilient urban spaces that offer a higher level of service to their residents.
