![]() The third application may be the most important: getting buy-in and participation from the public. A second layer of specific applications translates the constant stream of raw data into alerts, insights, and action. According to a recent report by McKinsey, the first layer is a technology base that includes a critical mass of smartphones and sensors connected by high-speed communication networks. Within each of those subjects, three layers work together to make a smart city operate. Multiple agencies, consultants, and private firms track the development of smart cities, and there are eight generally recognized subjects that combine to make a city smart: Perhaps more so, smart cities require leaders with a long-term vision and people committed to collaboration.

What makes a city smart? Generally, it requires intelligent IoT solutions that optimize infrastructure and government to better engage citizens in the management of services. After about 10 years, they are entering a new developmental phase as digital solutions are harnessed to deliver real-time information to users and providers through connected applications. Much of this work is in its infancy, as cities build a “smart” foundation. Politicians and urban planners have been laying the groundwork to leverage technology to meet the demands of residents and provide greater efficiencies in delivering services in the quest to create these smart cities. How will all of these residents move through and around cities, and how will cities provide energy, water, sanitation and other basic needs? By leveraging technology based on the Internet of Things (IoT) and integrating an online population into new systems that make a city work-a new and evolving smart city. ![]() Global cities now account for more than half of the world’s population, and the United Nations projects the number to balloon to 68 percent by mid-century. As more people surge into urban areas around the world, the swelling population strains infrastructure and services. ![]()
