The City Science Initiative at the MIT Media Lab is exploring technologies to help develop cities that facilitate the creation of desirable urban features, such as shared electric vehicles, adaptable living environments, and flexible work spaces. Our goal is to design urban cells that are compact enough to be walk able and foster casual interactions, without sacrificing connectivity to their larger urban surroundings. These cells must be sufficiently autonomous and provide resiliency, consistent functionality, and elegant urban design. Most importantly, the cellular city must be highly adaptable so it can respond dynamically to changes in the structure of its economic and social activities.

Massachusetts Institute of Technology (2014) 6 Academic Tracing the genealogy of the word smart in the label smart sustainable city can contribute to an understanding of how the term smart is being loaded. In marketing language, smartness is cantered on a user perspective. As a result of the need for appeal to a broader base of community members, smart serves better than the more elitist term intelligent. Smart is more user‐friendly than intelligent, which is limited to having a quick mind and being responsive to feedback. Smart Sustainable City is required to adapt itself to the user needs and to provide customized interfaces. User perspective, user friendly, responsive, adaptability. Nam et al. (2011)
