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.[n 1]

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.[n 2] The terms 'intelligent city' and 'digital city' are also used.[n 3]

The European Union (EU) has devoted constant efforts to devising a strategy for achieving 'smart' urban growth for its metropolitan city-regions.[n 4][1]

Arup estimates that the global market for smart urban services will be $400 billion per annum by 2020.[n 5] Notably 'smart' cities include Chicago, Boston, Barcelona and Stockholm.[n 6]

Theories about smart cities are somewhat lacking as everything in the city might be informed by information technologies, but a useful review of this perspective was produced as part of the FuturICT initiative in 2012.[2][3]


The term smart city is still quite a fuzzy concept and is used in ways that are not always consistent. Here are a number of definitions:


It has been suggested that a smart city uses information and communication technologies (ICTs) to:

Three dimensions[edit]

Intelligent cities (communities, clusters, regions) were defined as multi-layer territorial systems of innovation that bring together knowledge-intensive activities, institutions for cooperation in learning and innovation, and digital spaces for communication and interaction in order to maximize the problem-solving capability of the city. The distinctive characteristic of an intelligent city is the high performance in the field of innovation, because innovation and solving of new problems are main features of intelligence.[n 10][n 11]

Intelligent cities evolve towards a strong integration of all dimensions of human, collective, and artificial intelligence in a city. They are constructed as multi-dimensional agglomerations combining three main dimensions (Komninos 2006, 17-18; Komninos 2008, 122-123).

Thus the concept of ‘intelligent city’ integrates all the three aforementioned dimensions of the physical, institutional and digital spaces of an agglomeration. Consequently, the term ‘intelligent city’ describes a territory with

Sensor networks and data management[edit]

Sensor networks, including wireless sensor networks and in the Internet of Things technologies are used to monitor many aspects of a city in real time,[16] including traffic, power networks, street lighting and water/sewage systems.[17][18][19]

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. Examples include Xively and Wikisensing.[20][21]


The main arguments against the superficial use of this concept in the policy arena are:[n 8]

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."[n 8]

  1. ^ 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"
