In December 2011,
462-535: A city saves time and flexibility by driving, the resultant excessive driving of the community causes traffic congestion and environmental issues . This situation is worsened when public transportation services get little attention due to the use of personal vehicles. Philosophical predecessors of smart cities can be found in utopian works such as New Atlantis (1626). Another was Ebenezer Howard 's 1898 concept of Garden Cities . These were dense, size-limited cities founded in rural areas by private groups, combining
539-439: A conventional "transactional" relationship with its citizens. Yet, the term is open to many interpretations. Many cities have already adopted some sort of smart city technology. Smart city initiatives have been criticized as driven by corporations, poorly adapted to residents' needs, as largely unsuccessful, and as a move toward totalitarian surveillance . Historically, cities functioned as centers of innovation, and
