Abstract

:
Smart cities employ technology and data to increase efficiencies, economic development, sustainability, and life quality for citizens in urban areas. Inevitably, clean technologies promote smart cities development including for energy, transportation and health. The smart city concept is ambitious and is being refined with standards. Standards are used to help with regulating how smart cities function and contributing to define a smart city. Smart cities must be officially recognized by national and international authorities and organizations in order to promote societal advancement. There are many research and review articles on smart cities. However, technical standards are seldom discussed in the current literature. This review firstly presents the study of smart city definitions and domain. The well-known smart city standards will be presented to better recognize the smart city concept. Well-defined standards allow meaningful comparisons among smart cities implementation. How smart city initiatives make a city smarter and improve the quality of life will be discussed for various countries. This review highlights that technical standards are important for smart cities implementation. This paper serves as a guide to the most recent developments of smart cities standards.

1. Introduction

By 2050, it is expected that 66% of the global population will dwell in urban regions [1]. The challenge will be to supply these populations with essential resources including sufficient energy, clean water, and safe food while simultaneously warranting complete economic, social, and environmental sustainability.
Several cities today have aspirations of transforming into the smart cities of tomorrow. However, the challenges to be overcome to accomplish this include the planning of a complicated plan that comprises public and private participants, product vendors, and information technology infrastructure providers. A smart city needs the foundation of standards-based information technology infrastructure that fulfils and supports a wide range of requirements and can adapt to novel technologies, such as advanced sensors, measurement and analytics tools, and solutions driven by machine learning and artificial intelligence. Smart city development requires support from public organizations, citizens, state and local government, and private enterprises. The benefits of a smart city include the creation of major prospects for sustainability, disaster prevention, business, public safety, and quality of life enhancements. However, there are key challenges that need to be addressed for a smart city including:
Commodification: As discussed by Gandy and Nemorin [2], a major concern regarding the smart cities’ development is the motivation to support this worldwide initiative, from the pursuit of new markets by transnational corporations. Corporate organizations are keen to mine personal data, such as biometric data [3]. Data brokers could create consumer profiles including biometric information, and identities can be located and tracked as citizens move in a smart city. These profiles can also intensify commodification by mining the freshly available sources of data, with the ubiquity of sensors as dynamic data collection points.
Social and digital exclusion: In designing smart cities solutions, it is important to use suitable means to engage and empower population groups which are hard to reach, such as citizens living in poverty and/or social exclusion, migrants, younger and older people, or people with disabilities [4]. Smart city technologies should be made affordable and able to be accessed by all groups of consumers. A smart city should be an age-friendly environment. The World Health Organization defines age-friendly environments as ones which “foster health and well-being and the participation of people as they age” [5]. These environments are accessible, equitable, inclusive, safe and secure, and supportive. Senior citizens may experience negative attitudes and discrimination based on their age. Creating age-friendly environments acknowledges diversity, fights ageism, and ensures that everyone has the opportunity to fully participate.
Privacy and surveillance: Privacy becomes a major concern when the data collected could lead to linking or identifying an individual, especially when gathered from numerous information sources. Data storage by governments is generally non-transparent. The likelihood for cross-sharing data within government services could lead to third parties to have access to the data, where the provider has no intention for it to happen. Zoonen [6] constructed a four-quadrant privacy framework to theorize if and how smart city technologies and urban big data produce privacy concerns among the people in these cities. The framework is developed according to two recurring dimensions in research towards people’s concerns about privacy: one dimension signifies that people see specific data as more personal and sensitive than others, the other dimension signifies that people’s privacy concerns vary according to the purpose for which data is gathered, in contrast to the surveillance and service purposes which are the most dominant. The work concludes that the smart technology options and the use of specific data and analytic tools are important factors to comprehend people’s privacy concerns in smart cities, as well as to their awareness of what type of data to use to serve a purpose. A smart city should address (1) an applied need to substantiate the empirical relation between purpose, and technologies, and; (2) to produce a theoretical and situated comprehension of people’s privacy anxieties in smart cities.
In addition, building a smart city is a gigantic task as there are several working parts and components involved, namely the smart cities domains [7]. Many smart cities are not constructed from scratch or all in a single attempt. Smart city development is a gradually evolving process that witnesses the city becoming smarter, bit by bit. As time progresses, the individual regions of smartness develop together and interconnect, but on the condition for them using the same consistent technical rules that are stipulated by technical standards.
Several researchers have reviewed smart city projects from different perspectives. Camero and Alba [8] explored the computer science and information technology used for a smart city. There is no agreement on a smart city definition and in fact, several definitions are being developed. One explanation is for the iterative process where cities become smarter as time progresses. There are very few studies on the inclusion of policy and urban planning recommendations in information technology and computer science literature.
Caird and Hallett [9] examined the creation of appropriate, valid, credible, and valuable approaches to smart city evaluation by studying conceptual, measurement, and evaluation challenges for five UK smart city projects. Caird and Hallett [9] identified that a critical challenge for evaluation design is in creating standardized smart city development and performance indicators that give useful citizen and city-centered evaluations. There is a significant amount of work on standardization and smart urban metrics driven by international standards organizations. Specifically, the Smart and Sustainable Cities and Communities Coordination Group advises on European interests and requirements concerning standardization on Smart and Sustainable cities and communities. The International Organization for Standardization (ISO) has concurred on standards for ‘Smart Community Infrastructures’ performance metrics. ISO Technical Report 37150:2014 (Smart community infrastructures—Review of existing activities relevant to metrics) [10] reports community infrastructures including water, energy, waste transportation, and Information and Communications Technology (ICT). The standard concentrates on the technical features of current activities which are available. Political, societal, or economic aspects are not studied in this standard. ISO Technical Report 37151:2015 (Smart community infrastructures—Principles and requirements for performance metrics) [11] details the principles and stipulates requirements for the definition, identification, optimization, and harmonization of community infrastructure performance metrics, and gives recommendations for analysis, including smartness, interoperability, synergy, resilience, safety, and security of community infrastructures. Funded by the European Union HORIZON 2020 program, the CITYkeys project [12] is an important European Commission EUROCITIES initiative that aims to create acceptable city performance measurement frameworks: Key Performance Indicators. The initiative creates standardized data collection processes to increase the adoption rate of smart city solutions. It is anticipated that comparable, scalable, and replicable smart city solutions can be achieved across cities. The authors concluded that standardized smart urban metrics and indicators are not widely adopted by cities while the development of standards is at the early stages.
Hasija [13] examined the current global advancements in smart city initiatives. The study was categorized into three themes, namely data access and collection, end-user utility, and economic feasibility of different solutions. The economic viability is crucial to the success of a smart city initiative. The potential ideas to enhance city operations could not be delivered if it they are economically unsustainable. For business strategies, prudent analysis is required to examine the trade-offs that determine the efficacy of such initiatives. A bike-sharing scheme is an affordable and convenient mode of transportation in China. However, not all bike-sharing companies are successful. Some of the issues contribute to the failure of bike-sharing initiatives include (1) no regulation: bikes could end up in different places and be dumped along city streets; (2) lack of operational sustainability: many bike-sharing platforms do not need a security deposit; (3) no optimization: lack of consideration for how and where the bikes should be located to maximize utilization and to avoid bikes piling up on streets.
Anthopoulos [14] examined twenty smart cities projects of various scales in different countries and continents. Furthermore, the review documented the challenges that the cities meet as they work towards being a smart city. The review examines smart cities in relation to climate change, sustainability, natural disasters, and community resiliency. A smart city project is complex and expensive. Anthopoulous [14] firstly examined the project management guidelines and frameworks for agile and complex projects, including a smart city. ISO 21500:2012 Guidance on project management is an international standard that can be used by private or public organizations for all kinds of projects. The aim is to provide a guide to project managers on how to apply project management disciplines into a business environment to increase the possibilities for enhanced business results and project success. An important aspect is the use of the common language and processes by all project stakeholders, which enhances communication and cooperation. ISO 21500 gives a high-level description of concepts and processes to create good practices in project management. The cities reviewed focuses on the project management perspective including scope, organization, time, cost, quality, risk, and procurement. The smart city projects are well documented with great detail in the project development. However, there is a lack of discussion on technical standards of the smart city projects apart from project management.
Van Winden and Van den Buuse [15] analyzed the procedures of upscaling, concentrating on smart city pilot projects where numerous stakeholders with dissimilar missions, agendas, and incentives work together. If technical standards can be smoothly adapted to fit with the geospatial context, then the solution becomes more attractive to many cities. Numerous works on smart cities have been conducted and review literature for smart cities exists. However, most recent literature lacks discussions on an important topic of international standards for smart cities. International standards are technical standards developed by international organizations. International standards can greatly assist tailor-made solutions development for bespoke conditions of a city. Standards stipulate the anticipated level of performance and technologies compatibility. Standards are generic metrics that allow solutions to be benchmarked and compared. Section 2 presents the definitions and domains of smart cities. As international standards are the basis of building a smart city, Section 3 exhibits international standards for a smart city. Section 4 describes the current smart city projects for various countries and the standards adopted. The conclusion is given in Section 5.

2. Smart City Definitions and Domains

One of the reasons behind the lack of unified definitions of a smart city is because of the various entities involved and the functions the smart city provides. Hence, existing definitions can vary greatly. There are several definitions for a smart city which are defined by various organizations and stakeholders.
The most common consensus is that the smart city employs various kinds of digital and electronic technologies to transform the living environments with ICTs [16,17]. Deakin [18] labeled the smart city as a city that employs ICT to meet the market (the citizens’) needs. There is a need for larger community involvement to achieve a smart city. A smart city does not simply contain ICT technology but has also developed the technology to achieve positive impacts to the local community. Some definitions for a smart city from major professional organizations and government agencies are given as follows:
  • Association of Southeast Asian Nations [19]: “A smart city in ASEAN harnesses technological and digital solutions as well as innovative non-technological means to address urban challenges, continuously improving people’s lives and creating new opportunities. A smart city is also equivalent to a “smart sustainable city”, promoting economic and social development alongside environmental protection through effective mechanisms to meet the current and future challenges of its people, while leaving no one behind. As a city’s nature remains an important foundation of its economic development and competitive advantage, smart city development should also be designed in accordance with its natural characteristics and potentials”.
  • British Standard Institution [20]: A smart city is an “effective integration of physical, digital and human systems in the built environment to deliver a sustainable, prosperous and inclusive future for its citizens”.
  • Department for Business, Innovation and Skills, UK [21]: “A Smart City should enable every citizen to engage with all the services on offer, public as well as private, in a way best suited to his or her needs. It brings together hard infrastructure, social capital including local skills and community institutions, and (digital) technologies to fuel sustainable economic development and provide an attractive environment for all”.
  • European Commission [22]: “A smart city is a place where traditional networks and services are made more efficient with the use of digital and telecommunication technologies for the benefit of its inhabitants and business. A smart city goes beyond the use of ICT for better resource use and less emissions. It means smarter urban transport networks, upgraded water supply and waste disposal facilities and more efficient ways to light and heat buildings. It also means a more interactive and responsive city administration, safer public spaces and meeting the needs of an ageing population”.
  • Innovation and Technology Bureau, Hong Kong [23]: “Embrace innovation and technology to build a world-famed Smart Hong Kong characterised by a strong economy and high quality of living”.
  • Institute of Electrical and Electronics Engineers Smart Cities Community [24]: A smart city gathers government, technology, and society to achieve a minimum of the following factors: smart mobility, a smart economy, a smart environment, smart cities, smart governance, smart people, and smart living.
  • International Electrotechnical Commission [25]: “A smart city is one where the individual city systems are managed in a more integrated and coherent way, through the use of new technologies and specifically through the increasing availability of data and the way that this can provide solid evidence for good decision making”.
  • Japan Smart Community Alliance [26]: The expression “Smart Community” is more widespread than “Smart City” in Japan [22]. “A smart community is a community where various next-generation technologies and advanced social systems are effectively integrated and utilized, including the efficient use of energy, utilization of heat and unused energy sources, improvement of local transportation systems and transformation of the everyday lives of citizens”.
  • Ministry of Housing and Urban Affairs, India [27]: “The conceptualisation of Smart City, therefore, varies from city to city and country to country, depending on the level of development, willingness to change and reform, resources and aspirations of the city residents. A smart city would have a different connotation in India than, say, Europe. Even in India, there is no one way of defining a smart city”.
According to the above, the similarity and differences in smart city definitions can be summarized as follows:
  • Similarities:
    Enhancement of living standards by making informed decisions with advanced technologies to collect, process, and evaluate data.
    Systems are integrated to exchange information.
    Citizens are better informed about their surroundings.
    Sustainability and environmental conservation should be maximized.
  • Differences:
    Smart city domains or elements e.g., transport, energy, and health (explained in the following section) can be different due to regional interests.
From the above summary, it is shown that for a city to become smart, multiple sources of data from a range of urban activities and domains must be connected to reveal opportunities to bring innovation to today’s connected citizens. Deloitte [28] stated that a smart city is driven by the innovation success of six key domains including:
  • Energy and environment: Sustainable growth is created by technology and cities make better use of resources from electronic sensors that monitor leakages, as well as gamification and behavioral economics to support citizens to conduct considerate decisions on resource utilization [29]. Renewable energy including solar and wind will be important sources of energy generation [30,31,32]. Data analytics will be used to enhance energy and power system operation [33];
  • Economy: The economy will be affected by digitization and disruptive technologies, which will change the needs of several types of jobs. Smart cities need to create strategies to adopt future jobs that will power Industry 4.0 and beyond [34];
  • Safety and security: As criminals will make use of technology to commit advanced crimes, public safety and security authorities will also use technology for crime prevention by assessing multiple streams of social and crowdsourced information, including super-resolution images [35] and image fusion [36];
  • Health and living: The lives of citizens are enhanced with technology and connectivity. Connected communities are achieved with smart buildings. Enhanced social programs and innovated health care sector are data-driven [37];
  • Mobility: The integrated mobility systems include autonomous vehicles and shared mobility services achieved with the Internet of Things (IoTs). The concept of IoTs occurs when devices are communicating with other devices on behalf of people and will dominate the future of Internet communications [38]. Advanced analytics allow citizens and goods to travel in ways that are safer, cheaper, cleaner, and faster [39];
  • Education and government: Technological advancement will aid government procedures and give a seamless experience to businesses. Smart cities use analytics to assist authorities to create insight-driven policies, monitor performance and outcomes, allow constituent engagement, and enhance government efficiency. Data and analytics will also assist next-generation teachers to familiarize their counselling and teaching for greater student achievement. More creative and personalized education plans can be created such as virtual learning environments [40].
Similarly, Giffinger et al. [41] described the smart city as having six domains, including:
  • Smart economy: Consists of features surrounding economic competitiveness including entrepreneurship, innovation, flexibility, the productivity of the labour market, trademarks, and participation in the global market.
  • Smart people: Concerns not only the level of qualification or education received by citizens but also additional social interactions and perceptions of public life.
  • Smart governance: Concerns political involvement, citizen services, and administration functions.
  • Smart mobility: Includes local and global accessibility with the presence of ICTs and sustainable and relevant transport systems.
  • Smart environment: Concerns attractive natural conditions including green space, less extreme climate, reduced pollution, resource management, and working to achieve environmental protections.
  • Smart living: Includes many features of quality of life composed of health, housing, culture, tourism, and safety.
It is worth noting that there are other domains including:
Smart water [42,43]: Smart water systems employ IoT enabled sensors to collate real-time data. With precise and reliable data, smart water systems can drive great transformations in water sector transparency and accountability. There will be governance improvements, risk reductions, water quality control and eventually a novel business cases for water sector investment [43]. The data allows water facilities optimization by detecting leaks or observing how water is distributed in the water network. The optimization model empowers citizens to make better decisions about water management. Smart sensors can detect water pipe leaks and quickly inform engineers to take action and resolve the issue. Smart water is critical as an estimated 3.3 billion litres of water is wasted daily in Wales and England due to leaks in water networks [42].
Smart health [44,45]: The European Commission [44] described smart health permits healthcare providers to reduce illnesses occurrence, to care for patients more efficiently, and to cure illnesses more effectively. Smart health also reduces healthcare expenditure in the growing aging population. Smart health solutions consist of technological developments in portable and mobile devices, sensor technology, application development, mobile data connectivity, cloud computing, and big data analytics, with new ideas on patient co-management, health tracking of remote neighborhoods, and minimizing unhealthy lifestyles. Deloitte [45] stated that smart health consists of five features, including to: (1) empower proactive health and well-being management to make choices that can proactively improve health, well-being, and quality of life to reduce adverse health outcomes in the future; (2) foster a sense of community and well-being with virtual and in-person community meetings; (3) enable digital technology and behavioral science with mobile applications for users to enter and track data and seek information, e.g., fitness tips and recipes, and deploy the use of coaching and guide to support adherence and uptake of behaviors associated with healthy, active living; (4) meaningfully use data to improve outcomes and allow users to track their progress. Consent would be requested from users to share and use data, to enhance the program and for it to make improved recommendations; (5) enable new and innovative ecosystems to consist of the collaboration of businesses with all kinds of organizations e.g., government agencies and academia to align on health outcome measures and coordinate on investments in communities.
Smart waste [46,47]: Interreg Europe [47] described smart waste as being used “to improve public policy instruments supporting innovation within waste management procedures. The final result? Smarter, more effective, sustainable, and cost-efficient waste management, benefiting all territorial stakeholders”. In the UK, illegal waste activity including fly-tipping costs the UK economy approximately £600 M annually [46]. The present systems for monitoring commercial and household waste are out-of-date and mainly paper-based. Smart waste employs technology including blockchain [48], electronic chips, and sensors for monitoring waste, waste containers, and waste vehicles. Smart waste is an element of smart living and smart environments.
In summary, a smart city is an ambitious and crucial transformation of many cities worldwide. Benefits include improved living conditions are reaped from several sectors/domains. However, a smart city consists of the development and application of novel technologies. There is a need for standardized uniform engineering or technical criteria, methods, processes, and practices. The next section examines how international standards help to build a smart city.

3. International Standards for Smart City

The International Organization for Standardization (ISO) has described standards as “the first step towards the holy grail of an interoperable, plug-and-play world where cities can mix and match solutions from different vendors without fear of lock-in or obsolescence or dead-end initiatives” [49]. International standards are best practice created by global experts. Standards can be used to benchmark functional and technical performances. Standards make sure that technologies deployed in cities are efficient, safe, and well-integrated.
The largest and most well-established international standards organizations include ISO [50], the International Electrotechnical Commission (IEC) [51], and the International Telecommunication Union (ITU) [52] which were founded between 50 and 150 years ago. The description of these organizations are as follows:
  • ISO is a non-governmental and independent global organization with 164 national standards bodies as members. The standards body for each country (e.g., Bureau de Normalisation (NBN) in Belgium and Ghana Standards Authority (GSA) in Ghana) works directly with ISO and aims to minimize diversity in technical definitions. ISO standards are applied in various fields including quality management, environmental management, IT security, energy management, health and safety, and food safety [50].
  • IEC is the world’s forefront organization for the groundwork and publication of international standards for electronic, electrical, and relevant technologies, i.e., “electrotechnology” [51]. IEC described technical and international standards as reflecting “agreements on the technical description of the characteristics to be fulfilled by the product, system, service or object in question. They are widely adopted at the regional or national level and are applied by manufacturers, trade organizations, purchasers, consumers, testing laboratories, governments, regulators and other interested parties”. Standards help researchers, industry, regulators, and consumers globally to achieve an optimal experience and meet mutual needs for various countries. Standards establish one of the vital bases for the elimination of technical obstacles to trade.
  • ITU is the United Nations bespoke agency for ICTs and enables global connectivity of communications networks [52]. ITU manages international satellite orbits and radio spectrum, creates the international standards that allow technologies and networks to be continuously interconnected, and aims to enhance ICT access for global communities.
The above organizations have developed standards to specify and establish definitions and methodologies for a set of smart cities indicators. For example, ISO 37122:2019 (Sustainable Cities and Communities—Indicators for Smart Cities) [50] intends to give a holistic set of indicators to evaluate advancement in developing a smart city. The standard includes multiple domains including education, energy, economy, environment and climate change, finance, governance, health, housing, population and social conditions, recreation, safety, solid waste, sport and culture, telecommunication, transportation, urban/local agriculture and food safety, urban planning, wastewater, and water. The World Council on City Data is a prominent initiative in using standardized city data to create smart cities [53]. The initiative hosts a network of innovative cities dedicated to refining quality of life and services with open city data and delivers a reliable and holistic platform for standardized urban metrics. The World Council on City Data is an international hub for international organizations, education partnerships across cities, corporate partners, and academia to expand innovation, envisage alternative futures, and construct enhanced cities. The initiative developed the first city data standards, namely, ISO 37120 (Sustainable development of communities: Indicators for city services and quality of life).
The IEC has identified over 1800 standards that already impact smart cities [54]. The SyC Smart cities promote the coordination of standards efforts of several IEC committees and other organizations, including ISO, to promote the development of standards to achieve integration, interoperability and effectiveness of city systems. SyC Smart City is presently developing IEC 63152 as the best practice tool for city planners. Considering the higher frequency of natural disasters and destruction in some urban areas, IEC 63152 proposes guidelines to sustain several city services after a disruption occurs. IEC 63152 provides the fundamental concepts of how several city services can cooperate to uphold the supply of electricity.
ITU established Study Group 20 and United for Smart Sustainable Cities to develop standard activities in supporting the utilization of ICTs in a smart city [55]. These standards focus on terminologies for the IoTs and smart cities, high performing ICT infrastructures requirements, and the interoperability between various ICT or IoT networks. The ICT standard consists of four layers, namely the “application and support layer”, “data layer”, “communication layer”, and “sensing layer”.
In addition to the above three organizations, the Institute of Electrical and Electronics Engineers (IEEE) also develops international standards for smart cities. One of the most well-known IEEE standards is the IEEE 802 family, which was established in the early 1980s and covers local area networks and metropolitan area networks [56]. In recent years, IEEE has established the IEEE Smart Cities Community, which “brings together IEEE’s broad array of technical societies and organizations to advance the state of the art for smart city technologies for the benefit of society and to set the global standard in this regard by serving as a neutral broker of information amongst industry, academic, and government stakeholders” [57].
In 2017, the IEEE P2784 (Smart City Planning Guide) [58] was proposed to develop a framework that mentions the processes and technologies for planning the smart city transformation. A smart city requires a unified process planning framework to use IoTs to guarantee agile, interoperable, and scalable solutions that can be used and supported sustainably. The framework is a method for technology and cities integrators to plan for technology and innovative solutions for smart cities. Some of the most recent and first-of-a-kind standard initiatives from IEEE are presented in Table 1, Table 2, Table 3, Table 4 and Table 5.
In summary, this section has presented the need for international standards in smart city research and development. Some of the emerging standard projects are presented for various smart city domains. The next section examines the different smart cities projects worldwide and focuses on the standards examined and adopted.

4. Smart City Pilot Projects

Having examined the importance of international standards and the emerging ones, the following section presents some of the smart cities pilot projects from various countries. The focus is on the application of international standards. Following the alphabetical order of the continents, the smart cities pilot projects in Africa and Asia are presented in Table 6 and Table 7, respectively.
In Australia, the Australian Government established the Smart Cities Plan in 2016 [92]. The Plan highlights the Government’s vision for productive and habitable cities that boost innovation, upkeep growth and generate jobs. The Plan embodies a framework for a cities policy at the federal level. City Deals are the important drivers for executing the Smart Cities Plan. They are partnerships between the three levels of government and the community to strive for a shared vision for liveable and productive cities. Standards Australia is the country’s leading independent, non-governmental, not-for-profit standards organization [93]. The organization is actively participating in national and international discussions on smart cities, including being involved in the ISO Technical Management Board United Nation Sustainable Development Goals Taskforce. The task force will: revisit the mapping of ISO standards to the Sustainable Development Goals; identify the importance of Sustainable Development Goals for ISO, leading to the design of a database that can be used by businesses and organizations to determine the useful standards in promoting Sustainable Development Goals; create guidance for committees on how to proactively identify the right partnerships including the United Nations and other international organizations; offer recommendations for which organizations including ISO should work in standards promotion to support Sustainable Development Goals.
The smart cities pilot projects in Europe, and North America and South America are presented in Table 8 and Table 9, respectively.
In summary, the review on some smart cities developments from various countries and international standards shows:
  • There is a lack of discussions on the use of international standards in implementing smart cities. It is important to acknowledge the currently available standards in development when structuring and developing a smart city.
  • With standards and technologies are swiftly evolving, many cities need to avoid getting locked into one vendor’s integrated solutions, which makes it more difficult for the city to share data with citizens, developers, and other cities.
  • International standards should be developed to address some of the most pressing challenges in a smart city, including potential solutions to a pandemic such as COVID-19 [112]. In combating COVID-19, ISO has made some standards freely available to the public, including ISO 13688:2013 (Protective clothing—General requirements) and ISO 19223:2019 (Lung ventilators and related equipment—Vocabulary and semantics) [113]. Simultaneously, IEC also decided to make some standards and most relevant normative references for critical care ventilators free of charge to industries who are creating products or converting their existing assembly lines to ventilator production [114]. In the current pandemic, many organizations and governments are sharing or publishing data. For example, government health agencies are publishing data concerning regional cases and deaths; symptom trackers are distributing data with researchers and making data public; technology companies are obtaining mobility data which can help us to understand the impact of the coronavirus on our lives. Standards need to support data interoperability, the ability of services and systems that create, exchange, and use data to have clear, shared expectations for the contents, context, and meaning of that data [115,116].

5. Conclusions

Smart cities are intelligent and sustainable cities. It is well-known that a smart city requires the use of novel technologies, including robust ICT infrastructures and sensor devices. First, this paper has revisited and identified some of the new smart city definitions. The definition of a smart city is continuing to evolve, and one must accept that different terminologies exist due to the different scope considered, e.g., the region and community involved. This paper then examines the smart city from the view of international standards. It is identified that numerous international standards are currently in development to develop a smart city and the old standards are being revised to become relevant to address current society needs. Six smart city domains were identified including smart energy, smart health, smart education, smart mobility, smart economy, and smart governance. There is a need for researchers and city developers to acknowledge the different kinds of standards currently available and in development, in order to build a city that is functional and sustainable. The review identified that international standards are by no means as yet pervasive: there is a need for smart city projects to present details on the international standards adoption, and its implications for a smart city. Well-defined standards allow meaningful comparisons among smart cities implementation. With the presence of many standard bodies, challenges exist if international standards are not agreed on by standards developers and users. This paper serves as a guide on international standards for smart city researchers and developers.
