Becoming a ‘smart city’ is not a goal, but rather a necessity. The current world population of 7.6 billion is expected to reach 8.6 billion in 2030, 9.8 billion in 2050, most of whom will live in cities.
Smart cities use different types of electronic sensors to collect data to manage assets and resources efficiently. The associated technologies are aimed at making cities data-driven to meet citizens’ needs; allowing systems and services to be responsive and act on data in real time. Smart cities are, in fact, complete ecosystems devoted to creating sustainable and resilient urban areas for the benefit of society and the local and global economies.
