Smart city/Overview of Smart Cities

false Encyclopedic articles belong at Wikipedia Overview A smart city is an urban area that uses digital technology, data, and connected infrastructure to improve how services are delivered while making the city more livable, efficient, and sustainable. It represents the strategic use of technology and modernized infrastructure to ensure that a city operates more efficiently, sustainably, and remains livable for its residents. Increasingly, the measure of an intelligent city is how effectively technology, infrastructure and public services improve everyday life for residents. By 2050, nearly 70 percent of the world's population will live in urban areas, placing enormous pressure on roads, power grids, and other urban systems, which is why smart city approaches have gained global attention. Definition One well-accepted definition describes a smart city as a city that connects the physical infrastructure, the information-technology infrastructure, the social infrastructure and the business infrastructure to leverage the collective intelligence of the city. More simply, a smart city can be understood as an urban center with technologies that use digital data to deliver better public services and more effective uses of resources. It focuses on efficiency, sustainability, and connectivity through integrated digital solutions. A smart city leverages advanced technologies and data-driven solutions to manage resources, services, and infrastructure efficiently. Core Concepts A smart city is comprised of several interconnected layers that work together. The Physical Layer includes the hard infrastructure such as roads, pipes, and buildings, but retrofitted with intelligence, involving smart meters for real-time power usage and automated waste collection systems. The Digital Layer acts as the nervous system of the city, consisting of sensors, cameras, and connectivity such as 4G, 5G, and fiber that collect and transmit data. The Service Layer is where the citizen interacts with the city, including online portals for government services that reduce the need for physical queues, and apps that provide real-time bus locations or allow reporting of broken streetlights. The Cognitive Layer involves the Integrated Command and Control Centers which are the brains where data from various departments is synthesized to make real-time decisions, such as adjusting traffic signal timings based on current congestion levels. Other key characteristics of a smart city include the use of the Internet of Things, big data, and artificial intelligence, which play a significant role in organizing urban infrastructure and managing resources. A smart city consists of six major components including smart governance, smart economy, smart citizens, smart mobility, smart environment, and smart living. It leverages interconnected devices and intelligent systems to enhance efficiency, promote sustainability, and address complex urban challenges effectively. Examples Singapore's Smart Nation Initiative represents one of the most comprehensive national-level smart city programs, integrating digital technologies across government services, transportation, healthcare, and urban planning. Songdo in the Republic of Korea serves as a purpose-built smart city where autonomous urban systems manage services with minimal human intervention. Valencia in Spain has implemented AI-driven autonomous urban systems for traffic management, public safety, and environmental monitoring. Shenzhen in China has developed autonomous public transportation systems including self-driving buses and smart traffic management. Dubai has launched a self-driving transport strategy aiming to make 25 percent of all trips autonomous by 2030. In India, Guna in Madhya Pradesh is on a journey towards becoming an autonomous city with integrated smart infrastructure. Beijing and Shanghai feature extensive networks of smart traffic lights adjusted based on real-time traffic, electronic toll systems, and AI-powered ride-hailing services. Zurich consistently ranks among the smartest cities in the world for infrastructure, technology, governance and quality of life. Category:Smart city
