With more than half of the world population now residing in cities and their sizes ever increasing, the concept of Smart Cities has recently emerged in order to better manage the challenges of dense urban living. Smart Cities use a variety of inputs and sensors to collect, process and interpret data in order to manage assets and resources efficiently. Data can be collected from citizens, devices, and assets to monitor and manage systems as diverse as traffic and transportation systems, power plants, water supply networks, waste management, law enforcement, information systems, schools, libraries, hospitals, emergency services and electrical grids.
Over 700 cities today aspire to be Smart Cities, including Singapore, Barcelona, Stockholm, and New York City. Each of these are exploring different approaches to find solutions that best serve their citizens.
