An urban region fully advanced in the infrastructure, communication, sustainable real estate and market viability sector is known as a 'smart city'. The main infrastructure is the information technology, which provides services to the residents. The economic development and activity is maintainable and incremental depending on the supply and demand. The focus of the smart city is improving the standard of living, economic growth, service efficiency and meet residential needs using urban technology and informatics. The sectors such as transportation and traffic management, government services, healthcare, energy, water, waste management, and advanced urban agriculture are expected to adopt the smart city technology. The smart city programs and technologies have been implemented in Southampton, Madrid, Stockholm, Amsterdam, Milton Keynes, and Barcelona so far.
