A smart city (also smarter city) uses digital technologies to enhance performance and wellbeing, to reduce costs and resource consumption, and to engage more effectively and actively with its citizens. Key 'smart' sectors include transport, energy, health care, water and waste. A smart city should be able to respond faster to city and global challenges than one with a simple 'transactional' relationship with its citizens. Other terms that have been used for similar concepts include ‘cyberville, ‘digital city’’, ‘electronic communities’, ‘flexicity’, ‘information city’, 'intelligent city', ‘knowledge-based city, 'MESH city', ‘telecity, ‘teletopia’’, 'Ubiquitous city', ‘wired city’.
Interest in smart cities is motivated by major challenges, including climate change, economic restructuring, the move to online retail and entertainment, ageing populations, and pressures on public finances. The European Union (EU) has devoted constant efforts to devising a strategy for achieving 'smart' urban growth for its metropolitan city-regions. Arup estimates that the global market for smart urban services will be $400 billion per annum by 2020.
The term smart city is still[when?] quite a fuzzy concept and is used in ways that are not always consistent. Here are a number of definitions:
- Giffinger et al. 2007: "Regional competitiveness, transport and Information and Communication Technologies economics, natural resources, human and social capital, quality of life, and participation of citizens in the governance of cities."
- Smart Cities Council[when?]: "A smart city is one that has digital technology embedded across all city functions."[full citation needed]
- Caragliu and Nijkamp 2009: "A city can be defined as ‘smart’ when investments in human and social capital and traditional (transport) and modern (ICT) communication infrastructure fuel sustainable economic development and a high quality of life, with a wise management of natural resources, through participatory action and engagement."
- Frost & Sullivan 2014: "We identified eight key aspects that define a Smart City: smart governance, smart energy, smart building, smart mobility, smart infrastructure, smart technology, smart healthcare and smart citizen."
- Institute of Electrical and Electronics Engineers Smart Cities: "A smart city brings together technology, government and society to enable the following characteristics: smart cities, a smart economy, smart mobility, a smart environment, smart people, smart living, smart governance."[when?]
- Business Dictionary: "A developed urban area that creates sustainable economic development and high quality of life by excelling in multiple key areas; economy, mobility, environment, people, living, and government. Excelling in these key areas can be done so through strong human capital, social capital, and/or ICT infrastructure."[when?]
- Indian Government 2014 : "Smart City offers sustainability in terms of economic activities and employment opportunities to a wide section of its residents, regardless of their level of education, skills or income levels."
- Department for Business, Innovation and Skills,UK 2013: "The concept is not static, there is no absolute definition of a smart city, no end point, but rather a process, or series of steps, by which cities become more 'liveable' and resilient and, hence, able to respond quicker to new challenges."
It has been suggested that a smart city (also community, Business cluster, urban agglomeration or region) use information technologies to: 1) Make more efficient use of physical infrastructure (roads, built environment and other physical assets) to support a strong and healthy economic, social, cultural development. 2) Engage effectively with local people in local governance and decision by use of open innovation processes and e-participation with emphasis placed on citizen participation and co-design. 3) Learn, adapt and innovate and thereby respond more effectively and promptly to changing circumstances.
They evolve towards a strong integration of all dimensions of human intelligence, collective intelligence, and also artificial intelligence within the city. The intelligence of cities "resides in the increasingly effective combination of digital telecommunication networks (the nerves), ubiquitously embedded intelligence (the brains), sensors and tags (the sensory organs), and software (the knowledge and cognitive competence)". Some major fields of intelligent city activation are:
|------- Innovation economy -------||------- Urban infrastructure -----||----------- Governance -----------|
|- Innovation in industries, clusters, districts of a city||- Transport||- Administration services to the citizen|
|- Knowledge workforce: Education and employment||- Energy / Utilities||- Participatory and direct democracy|
|- Creation of knowledge-intensive companies||- Protection of the environment / Safety||- Services to the citizen: Quality of life|
Platforms and technologies
The rise of new Internet technologies promoting cloud-based services, the Internet of Things (IoT), real-world user interfaces, use of smart phones and smart meters, networks of sensors and RFIDs, and more accurate communication based on the semantic web, open new ways to collective action and collaborative problem solving.
Online collaborative sensor data management platforms are on-line database services that allow sensor owners to register and connect their devices to feed data into an on-line database for storage and allow developers to connect to the database and build their own applications based on that data.
The city of Santander in northern Spain has 20,000 sensors connecting buildings, infrastructure, transport, networks and utilities, offers a physical space for experimentation and validation of the IoT functions, such as interaction and management protocols, device technologies, and support services such as discovery, identity management and security
University research labs have developed prototypes and solutions for intelligent cities. MIT Smart Cities Lab  focuses upon intelligent, sustainable buildings, mobility systems (GreenWheel Electric Bicycle, Mobility-on-Demand, Citycar, Wheel Robots); the IntelCities  research consortium developed solutions for electronic government, planning systems and citizen participation; URENIO has developed a series of intelligent city platforms for the innovation economy  focusing on strategic intelligence, technology transfer, collaborative innovation, and incubation, while is offering, through its portal, a global watch on intelligent cities research and planning; the Smart Cities Academic Network  is working on e-governance and e-services in the North Sea region.
Large IT and telecommunication companies such as CISCO, IBM, MS have developed new solutions and initiatives for intelligent cities as well. CISCO, launched the Global Intelligent Urbanization initiative  to help cities around the world using the network as the fourth utility for integrated city management, better quality of life for citizens, and economic development. IBM announced its SmarterCities  to stimulate economic growth and quality of life in cities and metropolitan areas with the activation of new approaches of thinking and acting in the urban ecosystem.
Major strategies and achievements related to the spatial intelligence of cities are listed in the Intelligent Community Forum awards from 1999 to 2010, in the cities of Suwon (South Korea), Stockholm (Sweden), Gangnam District of Seoul (South Korea), Waterloo, Ontario (Canada), Taipei (Taiwan), Mitaka (Japan), Glasgow (Scotland, UK), Calgary (Alberta, Canada), Seoul (South Korea), New York City (USA), LaGrange, Georgia (USA), and Singapore, which were recognized for their efforts in developing broadband networks and e-services sustaining innovation ecosystems, growth, and inclusion.
The main arguments against the superficial use of this concept in the policy arena are:
- A bias in strategic interest may lead to ignoring alternative avenues of promising urban development.
- The focus of the concept of smart city may lead to an underestimation of the possible negative effects of the development of the new technological and networked infrastructures needed for a city to be smart.
As a globalized business model is based on capital mobility, following a business-oriented model may result in a losing long term strategy: "The 'spatial fix' inevitably means that mobile capital can often 'write its own deals' to come to town, only to move on when it receives a better deal elsewhere. This is no less true for the smart city than it was for the industrial, [or] manufacturing city."

Hackathons bring together the good hackers in an organized competition to see who can make the biggest contribution to the community in 24 hours or less.
- Dept Business(2013) Page 7 "As consumers of private goods and services we have been empowered by the Web and, as citizens, we expect the same quality from our public services. In turn, public authorities are seeking to reduce costs and raise performance by adopting similar approaches in the delivery of public services. However, the concept of a Smart City goes way beyond the transactional relationships between citizen and service provider. It is essentially enabling and encouraging the citizen to become a more active and participative member of the community"
