City using integrated information and communication technology From Wikipedia, the free encyclopedia
A smart city is an urban area that uses digital technology to collect data and to operate/provide services.[1][2] Data can be collected from citizens, devices, buildings, cameras. Applications include traffic and transportation systems,[3] power plants, utilities, urban forestry,[4] water supply networks, waste disposal, criminal investigations, information systems, schools, libraries, hospitals, and other community services.[5][6] The foundation of a smart city is built on the integration of people, technology, and processes, which connect and interact across sectors such as healthcare, transportation, education, and infrastructure, etc.[7] Smart cities are characterized by the ways in which their local governments monitor, analyze, plan, and govern the city. In a smart city, the sharing of data extends to businesses, citizens and other third parties who can derive benefit from using that data.[8][9] The three largest sources of spending associated with smart cities as of 2022 were visual surveillance, public transit, and outdoor lighting.[10]
Smart cities integrate information and communication technology (ICT), and devices connected to the Internet of things (IOT) network to optimize city services and connect to citizens.[11][12] ICT cab be used to enhance quality, performance, and interactivity of urban services, to reduce costs and resource consumption and to increase contact between citizens and government.[13] Smart city applications manage urban flows and allow for real-time responses.[14] A smart city may be more prepared to respond to challenges than one with a conventional "transactional" relationship with its citizens.[15][16] Yet, the term is open to many interpretations.[17] Many cities have already adopted some sort of smart city technology.
Smart city initiatives have been criticized as driven by corporations,[18][19] poorly adapted to residents' needs,[20][21] as largely unsuccessful,[citation needed] and as a move toward totalitarian surveillance.[22]
Historically, cities functioned as centers of innovation, and the advent of the digital era presented opportunities and challenges to apply technology to create urban environments that are more efficient, sustainable, and livable.[23][24][25][26][how?][27]
The shift to smart cities necessitates a comprehensive restructuring of city management and operations, leading citizen participation, and methods of public service delivery.[26]
Cities seek to upgrade their infrastructure and service delivery, to promote social inclusion, technological adoption, and economic development.[27][28][29][26]
The transformation into a smart city involves modifications in planning, management, and operational processes.[30] This data can subsequently be analyzed to identify areas for improvement and optimize urban services.
The concept of smart cities emerged from cities' adoption[31] of information and communications technologies.[32][33]
ICTs present challenges given financial limitations, technical obstacles, and privacy and security concerns. ICTs are also not uniformly accessible across communities, contributing to the digital divide.[27]
No commonly accepted definition of "smart city" has emerged.[23][34]: 71 Evaluating smart city initiatives becomes difficult without agreement on parameters. It also hampers the ability to compare projects and identify best practices.[35][36][30]
Deakin and Al Waer list four factors that contribute to the definition of a smart city:[37]
Deakin defines the smart city as one that uses ICT to meet the demands of the market (the citizens of the city), based on community involvement.[38] Studies of smart city projects can be used as an alternative to difficult-to-define broad definitions in order to clarify what smart cities are.[23][39]
Notable disparities among smart city definitions include the relative focus on economic advantages versus environmental or social benefits and specific technology choices.[27]
Smart city definitions include:
The main issues surrounding smart city research include:[43]
An important motivation for smart cities is projected population growth. The UN forecasts global population to reach 9.6 to 13.2 billion by 2100, with cities absorbing 80% of this growth.[44]
An important goal of smart city initiatives is to use ICTs to address the tragedy of the commons problem.[how?] This phenomenon occurs when individuals acting in their own self-interest deplete a communal resource. For example, while each individual driver in 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.[45]
Philosophical predecessors of smart cities can be found in utopian works such as New Atlantis (1626).[46] Another was Ebenezer Howard's 1898 concept of Garden Cities.[43] These were dense, size-limited cities founded in rural areas by private groups, combining the benefits of the city and the country.[47] Other conceptions include those of Edward Bellamy, Frank Lloyd Wright, and Le Corbusier.[43][47] Critics of smart cities draw parallels between the weaknesses of these utopian visions and the weaknesses of smart cities today.[43]
The concept of "smart cities" emerged from global cities' recent adoption of information and communications technologies for urban use, which can be used to improve efficiency, sustainability, and livability in urban environments.[31][32][33] Some of the earliest interventions in urban planning include the use of computational statistical analysis by the Community Analysis Bureau in Los Angeles in the late 1960's[48] and the establishment by Singapore of the National Computer Board in 1981.[49]
The smart city concept experienced a major surge around 2005. Tech companies sought to create information systems to enhance operational efficiency for cities.[50][51][52][53]
A global movement emerged advocating smart cities.[citation needed]
IBM launched its Smarter Planet marketing initiative in 2008,[54] which included the IBM Smarter Cities Challenge. In 2010, Cisco Systems, with $25 million from the Clinton Foundation, established its Connected Urban Development program in partnership with San Francisco, Amsterdam, and Seoul. In 2011, a Smart City Expo World Congress in Barcelona attracted 6000 people from 50 countries. The European Commission in 2012 established the Smart Cities Marketplace, a centralized hub for urban initiatives in the European Union.[55] The 2015 Chancellor’s Budget for the United Kingdom proposed to invest £140 million in smart cities and IoT.[56] Smart city competitions were launched in the 2010s by Bloomberg Philanthropies, the Rockefeller Foundation, and the United States Department of Transportation.[19] In 2016, AT&T launched an alliance with Cisco, Deloitte, Ericsson, General Electric, IBM, Intel, and Qualcomm, with municipal partners Atlanta, Georgia; Chicago, Illinois; and Dallas, Texas.[19]
Key characteristics that define innovative urban environments include:[57]
It has been suggested that a smart city (or other community) uses information technologies to:[citation needed]
They evolve towards a strong integration of all dimensions of human intelligence, collective intelligence, and also artificial intelligence within the city.[69]: 112–113 [70] According to Mitchell, the intelligence of cities "resides in the increasingly effective combination of digital telecommunication networks (the nerves), ubiquitously embedded intelligence (the brain), sensors and tags (the sensory organs), and software (the knowledge and cognitive competence)".[71]
The physical components of IT systems are crucial to early-stage smart city development. Wired infrastructure is required to support the IoT and wireless technologies central to more interconnected living.[72] A wired city environment provides general access to continually updated digital and physical infrastructure. The latest in telecommunications, robotics, IoT, and various connected technologies can then be deployed to support human capital and productivity.[73][74]
Intelligence in smart cities has been demonstrated in three ways:[citation needed]
Examples of instrumentation intelligence are those implemented in Amsterdam.[77] This is realized through:[14]
Smart cities use data and technology to create efficiencies, improve sustainability, create economic development, and enhance quality of life factors for people living and working in the city.[citation needed] A variety of different datasets may need to be integrated to create a smart energy infrastructure.[78] Employment of smart technologies enables the more efficient application of integrated energy technologies in the city allowing the development of more self-sustaining areas or even positive energy districts that produce more energy than they consume.[79][how?]
A smart city is powered by "smart connections" for various items such as street lighting, smart buildings, distributed energy resources (DER), data analytics, and smart transportation. Amongst these things, energy is paramount; this is why utility companies play a key role in smart cities. Electric companies, working partnership with city officials, technology companies and a number of other institutions, are among the major players that helped accelerate the growth of America's smart cities.[80]
According to David K. Owens, the former executive vice president of the Edison Electric Institute, two key elements that a smart city must have are an integrated communications platform and a "dynamic resilient grid."[81]
Smart grids are an important technology in smart cities. The improved flexibility of the smart grid permits greater penetration of highly variable renewable energy sources such as solar power and wind power.[citation needed]
Energy Data Management Systems (EDMS) can help to save cities energy by recording data and using it to increase efficiency.[82]
For a smart city to function, it is necessary for it to manage an enormous amount of data collected through the embedded devices and systems in its environment.[83] This is also important for the cities growth and security.[84] Smart cities use a variety of data collection, processing, and disseminating technologies, in conjunction with data security and privacy measures, in attempting to encourage innovation and improve citizens' quality of life.[83] This can relate to topics including utilities, health, transportation, entertainment and government services.[83]
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.[85][86]
Electronic cards (known as smart cards) are another common component in smart city contexts. These cards possess a unique encrypted identifier that allows the owner to log into a range of government provided services (or e-services) without setting up multiple accounts. The single identifier allows governments to aggregate data about citizens and their preferences to improve the provision of services and to determine common interests of groups. This technology has been implemented in Southampton.[37]
Cognitive technologies, such as artificial intelligence and machine learning, can be trained on the data generated by connected city devices to identify patterns. The efficacy and impact of particular policy decisions can be quantified by cognitive systems studying the continuous interactions of humans with their urban surroundings.[87]
Bicycle-sharing systems are an important element in smart cities.[88]
Intelligent transportation systems and CCTV systems are also being developed.[89]
Retractable bollards allow to restrict access inside city centers (i.e. to delivery trucks resupplying outlet stores). Opening and closing of such barriers is traditionally done manually, through an electronic pass[90] but can even be done by means of ANPR cameras connected to the bollard system.[91]
According to McKinsey, smart city initiatives can have measurable positive impacts on the quality of life of its citizens and visitors.[92] The human framework of a smart city – its economy, knowledge networks, and human support systems – is an important indicator of its success.[93]
For example, arts and culture initiatives are common focus areas in smart city planning.[94][95] Innovation is associated with intellectual curiosity and creativeness, and various projects have demonstrated that knowledge workers participate in a diverse mix of cultural and artistic activities.[96][97]
Since mobility is a key area of smart city development, building a capable workforce through education initiatives is necessary.[93][clarification needed] A city's learning capacity includes its education system, including available workforce training and support, and its cultural development and exchange.[98]
Numerous Smart city programs also focus on soft infrastructure development, like increasing access to voluntary organizations and designated safe zones.[99] This focus on social and relational capital means diversity, inclusion, and ubiquitous access to public services is worked in to city planning.[74]
The development of a knowledge economy is also central to Smart city projects.[100] Smart cities seeking to be hubs of economic activity in emerging tech and service sectors stress the value of innovation in city development.[74]

Mobile devices (such as smartphones and tablets) are a key technology allowing citizens to connect to the smart city services.[101][102][103]
Smart cities also rely on smart homes and specifically, the technology used in them.[104][105][106][107][108]
Digital libraries have also been established in several smart cities.[109][110][111][112][113][114]
Additional supporting technology and trends include remote work,[115][116][117] telehealth,[118][119] the blockchain,[120][121] online banking technology,[122]
A "ubiquitous city", one concept of a smart city, provides access to public services through any connected device. U-city is an extension of the digital city concept because of the facility in terms of accessibility to every infrastructure.[123]
Criticisms of smart cities include:[18]

The United States allocated more than $160 million toward smart city initiatives. Challenges include traffic congestion, economic growth, crime, climate change, and public services.[citation needed]
The "smart communities" movement took shape as a strategy to involve more users in IT.[98] Primary issues included traffic congestion, school overcrowding and air pollution.[98]
EU members began working on smart city developments and ICT initiatives in the mid 2010s. The Digital Agenda for Europe framework emphasizes harnessing ICTs. The 2014-15 budget of the Horizon 2020 Research and Innovation program, included approximately 200 million Euros to expedite smart cities.[146][147]: 337–355 [148]
As of 2024 Estonia had proceeded furthest towards digitizing public services.
The African Union Commission pledged to utilize ICTs to advance sustainable urban development.[citation needed]
ASEAN Smart Cities Network (ASCN) is a collaborative platform to advance smart city efforts across ASEAN by catalysing bankable projects, and securing funding and support from ASEAN's external partners.[citation needed]
The Smart Cities Mission is a retrofitting and urban renewal program spearheaded by the Ministry of Urban Development.[149]
The New Urban Agenda emphasized the importance of smart city development, establishing a fundamental commitment for the UN's 193 member states.[150][151][152]
The most common characteristics of a "smart city" are networked infrastructure; emphasis on business-led urban development; social inclusion of various resident groups; and an emphasis on the environment.[23][27]
Smart city initiatives require collaboration and involvement from government agencies, businesses, community organizations, academia, and citizens. Collaborating with businesses and academia brings technical know-how and research capabilities.[153][154][155]
Collaborations with community organizations can improve equity and inclusivity.[27]
