Abstract

:
Infrastructure, service delivery, governance, and digital transformation stand as indispensable cornerstones, playing pivotal roles in the establishment of intelligent and sustainable urban centers. While the extant literature has underscored the significance of each of these elements, their interconnected and symbiotic relationship demands a more profound exploration. Grounded in a systematic review of the existing literature and relevant case studies, this paper explored the intricate interplay between digital transformation, infrastructure development, service delivery, and governance in contemporary society, all in the pursuit of cultivating smart sustainable cities. It contends that by collaboratively working together, these four pillars possess the transformative potential to turn cities into smart and sustainable cities. Digital transformation emerges as the catalyst, propelling innovation and efficiency, while infrastructure forms the bedrock for the seamless delivery of services. Effective governance, in turn, ensures alignment with the evolving needs of citizens. In essence, this study underscores the transformative power of combined action, asserting that the interdependent elements within can transform cities beyond merely having smart or sustainable status to become smart sustainable cities. This paradigm shift harmonizes technological advancements with the foundational goals of sustainable development, steering towards a holistic and inclusive urban future.

1. Introduction

The shift in discourse towards sustainable development has evolved from singular environmental concerns to a comprehensive focus on environmental, social, and economic development [1]. The notion of sustainable cities emerged as a response to growing concerns about environmental degradation, efficient use of scarce resources, and the imperative to create inclusive and resilient urban spaces [2]. This evolution led to the United Nations formally incorporating the development of sustainable cities and communities as one of its Sustainable Development Goals (SDG 11).
Sustainable cities, defined as inventive urban centers with a triple-bottom-line approach, prioritize social, economic, and environmental impact [3]. They aim to provide a sustainable and resilient habitat for the existing population while ensuring the potential for future generations to enjoy a similar quality of life [4,5,6,7]. The United Nations SDG 11 outlines these cities as dedicated to achieving environmental, social, and economic sustainability, with inclusivity, safety, and resilience.
In practical terms, sustainable cities commit to fortifying societies and economies, cultivating employment and entrepreneurial opportunities, and providing accessible and affordable housing. These cities focus on inclusivity and sustainable economic growth, minimizing resource consumption, waste, and emissions. Moreover, they prioritize investments in public transportation, the creation of green public spaces, and participatory governance, planning, and decision making [4,5,6,7,8].
Lately, running parallel to the sustainable cities movement is the emergence of smart cities, defined diversely based on attributes and contexts [9,10]. According to one perspective, smart cities employ technologies, pervasive computing, and digital tools to govern and manage information and resources, fostering real-time engagement with places, activities, and people [11]. They are characterized by economic efficiency, environmental sustainability, distinctive urban identity, favorable living conditions, and inclusive governance [8,9,10,12,13,14,15,16,17]. For example, smart cities prioritize intelligent infrastructure, energy conservation, enhanced mobility, and advanced waste management facilitated by smart technology [12,13,14,15]. Another perspective characterizes smart cities by six key attributes: a smart economy, smart people, smart mobility, smart environment, smart governance, and smart living [16,18,19,20,21]. This perspective focuses on smart humans, encompassing social innovation, smart citizenry, knowledge capital, and inter-organizational collaboration.
While the term ‘sustainable city’ has traditionally been favored, ‘smart city’ has gained momentum and is increasingly becoming the leading driver of urban sustainability and regeneration initiatives [22]. However, both models pose challenges and engender issues in alignment with the foundational goals of sustainable development [23]. The smart city concept, in particular, has faced criticism for being a technocentric approach to sustainability [24,25,26,27].
Numerous studies explored sustainable and smart cities separately, unveiling critical nuances for each type [8,24]. In response to the challenges of each concept, recent research focuses on integrating sustainability into smart city approaches and making sustainable city models smarter [4,5,6,7,23,24,26,28,29,30]. Beyond ‘smart’ and ‘sustainable cities’, the concept of ‘smart sustainable cities’ was introduced by the United Nations Economic Commission for Europe (UNECE). Scholars argue that these innovative urban centers leverage Information Communication Technologies (ICTs) to enhance the quality of life across economic, social, environmental, and cultural dimensions [4,5,6,7,8,27].
In recent years, research on the intersection of concepts of smart and sustainable cities known as smart sustainable cities has emerged. For example, Freeman (2017) probed into the origin and implementation of the smart sustainable city concept [23], while Bibri and Krogstie (2019) proposed a novel model for future smart sustainable cities [24]. Trindade et al. (2017) contributed a theoretical basis, emphasizing the relationship between sustainable urban development and smart cities [31]. Ahvenniemi et al. (2017) explored the difference between smart and sustainable cities, underlining that technologies in smart cities should enable sustainable development [32]. Martin et al. (2018) examined tensions in the visions and practices of smart sustainable cities, advocating for empowerment and inclusion [27]. Ibrahim et al. (2018) offer a roadmap for transforming a city into a smart sustainable entity [33].
However, three prominent challenges emerge concerning smart sustainable cities. Firstly, the impact of digital technology on environmental and social sustainability remains marginal [34,35,36,37]. Secondly, the fragmented approach to smart city development lacks inclusivity and consideration for local contexts [38,39,40,41,42]. Thirdly, existing research on smart sustainable cities primarily focuses on philosophies and conceptualization, neglecting to explore the models and relationships between foundational city elements—infrastructure, technology, service delivery, and governance [16,26,43,44]. While acknowledging the importance of the first two aspects, which have been explored to a certain extent both philosophically and empirically, this study focuses on addressing the third challenge. This is because there exists a significant research gap in understanding how the four vital city elements—infrastructure, digital technology, service delivery, and governance—synergize to transform a city into a smart sustainable entity. Consequently, this study explored the symbiotic relationship among these four key aspects to drive the development of smart sustainable cities, departing from the current trend in research in the field. In this context, the study initially conceptualizes the smart sustainable city, followed by delineating the roles of infrastructure, service delivery, governance, and digital transformation, along with their alignment. Furthermore, it analyzes the symbiotic linkages among these aspects, unravelling how these relationships manifest within the context of smart sustainable cities. For this purpose, the key research questions explored are as follows:
  • How is a smart sustainable city conceptualized in the wake of existing two categories such as smart city and sustainable city?
  • What roles do infrastructure, serviced delivery, digital transformation, and governance play in ‘smart cities’ and ‘sustainable cities’?
  • What are the interconnectedness and symbiotic relationships between the four aspects—infrastructure, service delivery, governance, and digital transformation—in the context of smart sustainable cities?
The novelty of this paper lies in elucidating how digital transformation, serving as a catalyst for innovation, can enhance infrastructure efficiency to facilitate effective and seamless service delivery, as well as foster effective governance. It is thus theorized that these aspects collectively contribute to the transformation of cities into smart sustainable entities.

2. Materials and Methods

The research adopted a qualitative methodological approach, with an extensive exploration of the extant literature and case studies to unravel the complexities inherent in smart sustainable cities. Given the interdisciplinary nature of the field, the sources of the literature span a diverse range, encompassing scholarly journal articles, books, book chapters, conference proceedings, reports, news articles, web articles, etc. The imperative was to gather the most pertinent literature from these varied sources, tailored to the study’s focus.
This investigation involved the formulation of a thorough search strategy, the curation of scholarly sources, the establishment of inclusion and exclusion criteria, the systematic organization of literature based on thematic elements, and the subsequent application of thematic analyses.

2.1. Search Strategy and Scholarly Sources

A comprehensive exploration of scholarly literature was undertaken to investigate published works centered on the primary domains of smart cities, sustainable cities, and smart sustainable cities, along with their associated elements. Given the study’s specific focus on the interplay between infrastructure, service delivery, governance, and digital transformation, the search was extended to encompass these interconnected facets within the aforementioned primary domains.
While scholarly peer-reviewed journal articles constituted the primary sources, valuable insights were also derived from diverse sources such as conference proceedings, books, reports, and online articles. Multiple databases, including Elseveie (Science Direct, Scopus), Wiley Online, Taylor and Francis/Routledge, Sage, Springer, EbscoHost, Google Scholar, Research Gate, Academia.edu, etc., were meticulously explored. Scholarly articles from the above-mentioned sources were systematically gathered, categorized, and subjected to critical assessment.
The search employed a strategic use of keywords, such as sustainable cities, smart cities, smart sustainable cities, ICT use in cities, Artificial Intelligence (AI) application in cities, digital transformation, infrastructure, service delivery, city flow, smart governance, strategies for smart sustainable cities, and opportunities and challenges of smart sustainable cities, to ensure a comprehensive and targeted retrieval of the relevant literature. While compiling the articles, four criteria—authenticity, credibility, representation, and meaning [45]—were employed to assess the quality of the articles.

2.2. Inclusion and Exclusions

The inclusion and exclusion criteria were guided by the research questions posed in this study. The inclusion criteria encompassed diverse dimensions of smart cities, sustainable cities, and smart sustainable cities. Additionally, it considered elements such as ICT use, digital transformation, infrastructure, service delivery, city flow, smart governance, dimensions, indicators, factors, challenges, opportunities, strategies, and other relevant aspects for the three city types—smart city, sustainable city, and smart sustainable cities.
Conversely, aspects that did not directly contribute to the investigation of interconnectedness and symbiotic relationships, as outlined in the research questions, were excluded. This entailed excluding considerations of economic, environmental, social, and cultural aspects from the scope of the study.

2.3. Organisation of the Literature

The initial search, involving screening keywords and abstracts, yielded over 500 articles. Following a scrutiny of the articles based on inclusion and exclusion criteria, and their subsequent organization under themes and subthemes, 184 articles emerged as pertinent and were selected for the final review and analysis. These chosen articles comprise 65.82% peer-reviewed journal articles, 6.63% conference proceedings, 8.67% books, 5.61% book chapters, 12.76% reports, and 0.51% theses (Table 1).
Furthermore, the selected articles were categorized according to the type of cities such as smart, sustainable, and smart sustainable cities. In addition to this, articles were categorized under various aspects such as infrastructure, service delivery, governance, and digital transformation. However, it was observed that many of the articles investigated multiple and overlapping aspects. However, a breakdown of the articles was conducted on the seven aspects mentioned above irrespective of the fact that an article might have investigated overlapping or multiple aspects. Figure 1 presents the distribution of articles across different elements/aspects of smart sustainable cities. An aspect-wise breakdown reveals that articles belonging to aspects related to smart cities, sustainable cities, and smart sustainable cities are 16.84%, 10.20%, and 8.16%, respectively. Infrastructure and service delivery were covered in 30.61% and 27.04% of articles, while digital transformation and governance were examined in 27.04% and 11.73%, respectively. This indicates a reasonable distribution of articles from varied authentic sources; therefore, the results are suitable for review and further analyses.

Moreover, the thematic analyses derived from the literature review were substantiated with evidence and examples drawn from case studies on symbiotic relationships observed in five countries: Singapore, Estonia, India, the UK, and Rwanda. Although no specific examples from individual cities were identified, the interdependent and symbiotic relationships observed across various sectors in the aforementioned countries demonstrated how their implementation at the city level could catalyze the transformation of cities into smart sustainable entities.

3. Conceptualizing a Smart Sustainable City

3.1. Smart Cities

The global discourse on smart cities lacks a universal consensus due to varying interpretations rooted in context and function. One perspective defines a smart city through the lens of ICT utilization, AI use, universal connectivity, extensive data use, social capital, business innovation, intelligent communities, and ecological sustainability [10,14,46]. Within this paradigm, a smart city is envisaged as an interconnected, instrumented, and intelligent urban space optimizing functionalities through ICT and advanced technologies such as AI [10,14,47,48,49]. Another viewpoint adopts a holistic approach, suggesting a city is smart if it excels in one or more of six key attributes: economy, mobility, people, environment, governance, and living conditions [16,18,19,20,50,51]. Cities in Europe and North America exemplify smartness by fostering entrepreneurship, innovation, ICT usage, connectivity, mobility, participatory governance, sustainability, and resident empowerment [33,52,53].
In the Global South, two distinct smart city models have emerged. One prioritizes specialized cities with ICT connectivity, sustainable infrastructure, and advanced transportation to foster entrepreneurship and economic activities [10,16,48,54]. The second model focuses on improving existing cities by enhancing infrastructure, services, transportation, environmental sustainability, and overall quality of life, emphasizing ICT connectivity, energy efficiency, an entrepreneurial ecosystem, aesthetic urban environments, and participatory governance [9,10,48,55].
Essentially, smart cities might have six characteristics that include smart governance, smart people, smart mobility, smart economy, smart environment, and smart living. However, the overarching and catalytic role of shaping these characteristics in a city is performed through the ubiquitous use of ICT. Thus, a smart city seamlessly integrates technologies, ubiquitous computing, and digital instruments into urban life [11,25,56]. This integration enables real-time precision in managing functions, processes, and engagements, resulting in enhanced economic efficiency, improved environmental sustainability, enhanced quality of life, effective service delivery, and distinctive urban images [32,56,57,58]. Moreover, smart cities are governed by participatory and inclusive governance models [9,14,16,17,18,33,55,59].

3.2. Sustainable Cities

The conceptualization of a sustainable city is diverse, with varying definitions [44,60]. The sustainable development of a city has been a primary focus in the last decades. Rogers (1998) defines a sustainable city as an urban area where an enhanced quality of life coexists with policies effectively curbing demands on external resources [61]. It evolves into a self-sufficient economic, social, and environmental system. Brugmann (1997) [62] and Meadows (1999) emphasize environmental performance, prioritizing measurement, and reduction in pollution, greenhouse gas emissions, energy, water consumption, and land loss, while improving water quality, recycling rates, green-space ratios, and forest preservation [63].
Contrastingly, Rode and Burdett (2011) advocate for socio-economic aspects, emphasizing social equity and a greener living environment for sustainable city development [64]. They argue for proximity, density, and variety to foster productivity and innovation. In essence, a sustainable city is environmentally safe, socially inclusive, and economically productive, enabling citizens to meet their needs without degrading the natural world [65,66]. The sustainable city advocates a systematic approach, recognizing vital relationships between people, socio-economic activities, and the environment [32,67]. Thus, a sustainable city has to achieve a dynamic balance among economic, environmental, and socio-cultural development goals, framed within a local governance system characterized by greater citizen involvement and inclusiveness [68]. Consequently, the sustainable city can be conceptualized in terms of four dimensions: environment, economy sociocultural, and governance. These dimensions given their interdependence, synergy, and equal importance should work in tandem to enable the attainment of sustainable city goals. This holistic perspective underscores the interconnectedness of ecological, social, and economic factors in sustainable urban development.

3.3. Smart Sustainable Cities

The term ‘smart sustainable city’ gained prominence in urban development around 2015 [26,44,69]. Despite the abundance of discourse on ‘smart’ and ‘sustainable cities’, specific studies on ‘smart sustainable cities’ are relatively scarce in academic journals. However, notable contributions from Scandinavian countries, especially Sweden and Norway, have emerged [26,43,44].
Investigations in this field, notably the scholarly contributions of Bibri and Krogstie (2017), have primarily focused on formulating precise definitions and enhancing the conceptual framework, specifically probing the intricate landscape of the smart sustainable cities field [44]. Höjer and Wangel (2015) envisage smart sustainable cities as an aggregate concept, asserting that smartness, sustainability, and urbanity must coexist for a city to qualify as smart sustainable [26]. This implies that cities can be sustainable or incorporate smart technologies independently, emphasizing the necessity for their amalgamation to define a smart sustainable city. Another approach combines sustainable development with ICT infrastructure and smartness in an urban environment, giving rise to the idea of a smart sustainable city [26,67,69]. Consequently, the dimensions of a smart sustainable city include the dimensions of a sustainable city performed and managed by digital technologies.
In the context of sustainability of smart cities, the focus of smart cities is on utilizing clean, climate-friendly technology to mitigate carbon emissions, a significant contributor to climate change and environmental degradation [34,35,36]. However, this emphasis on carbon reduction often overshadows other ecological concerns such as habitat loss, water scarcity, and ecosystem disruptions [36]. Despite technological advancements and reduced carbon emissions, the overall environmental impact of smart cities remains marginal. Additionally, challenges related to the supply chain influence the environmental sustainability of smart cities. For example, the development of smart devices needs the extraction of a wide range of resources (such as raw materials, minerals, metals, etc.) and the use of large amounts of oil and gas for energy production to power processes of production and distribution. The impact of such processes on the environment is enormous; moreover, it destabilizes the ecosystem.
While smart city initiatives prioritize economic and partially environmental factors, they often neglect social aspects [36]. Critics argue that smart cities and ICTs fail to address environmental and social challenges; instead, they contribute to them [37]. Moreover, it was argued that the sustainability of cities adopting smart technologies may be contingent upon the exploitation of resources and livelihoods elsewhere [37].
Furthermore, smart city initiatives typically adhere to a homogenous, systematic approach in theory but exhibit heterogeneity and fragmentation in practice, particularly in the Global South [38,39]. Many projects are implemented on a small scale, resulting in isolated urban bubbles that exacerbate socio-spatial struggles [40]. This fragmented development often lacks coordination and comprehensive planning, leading to a lack of inclusivity and consideration for local contexts [39,41,42].
Also, administrative geography significantly influences the deployment of smart city technologies, resulting in disparities in service accessibility among people [41]. In other words, local contexts and demands play a crucial role in shaping smart sustainable cities. Moreover, the integration of smart technologies with neoliberal urbanism presents sustainability challenges, as it prioritizes monetizable activities over holistic development [39]. Achieving sustainability in smart cities requires addressing economic, social, and environmental factors while considering local contexts and challenges. Thus, an effective high-level overview roadmap is crucial for planning this transformation process [67].
Nevertheless, a joint definition by the United Nations Economic Commission for Europe (UNECE) and the International Telecommunication Union (ITU) describes a smart sustainable city as an innovative urban center using ICTs to enhance the quality of life, improve urban operations and services, and boost competitiveness across economic, social, environmental, and cultural dimensions [23]. Transforming cities into smart sustainable cities requires an efficient process, considering city context, local interests, citizen well-being, readiness for change, and delivery of smart and sustainable solutions at all levels [33].

3.4. A General Conceptual Framework for Smart Sustainable Cities

Figure 2 presents a conceptual framework for a smart sustainable city. The major considered determinants of a sustainable city are economy, environment, socio-cultural aspects, and governance. On the other hand, infrastructure, service delivery, and governance all enabled and managed by digital technology are pivotal for smart cities. Despite the environmental and social sustainability challenges of smart cities [37,38,39], infrastructure, service delivery, governance, and digital technology contribute to both the sustainability and smartness of the cities [9,10,16,32,48,54,55,67,68]. Therefore, in this framework, it was considered that city infrastructure serves as the backbone, influencing socio-economic functions and impacting the environment. Efficient service delivery is essential for urban life’s smooth flow. Effective governance manages the economy, society, city dynamics, and service delivery. Digital transformation acting as a catalyst becomes a vital factor in enhancing the efficiency of these dimensions to benefit society. Thus, the study theorized that a symbiotic relationship exists between infrastructure, service delivery, governance, and digital transformation in crafting a smart sustainable city. However, since the focus is on infrastructure, service delivery, and governance enabled by digital technologies, the conceptualization of smart sustainable cities was kept within the context of the four above-mentioned aspects and detailed discussion on the environmental and social sustainability and impact of fragmented approach was kept out of the scope of the study.

4. Role of Infrastructure, Serviced Delivery, Governance, and Digital Transformation in ‘Smart Cities’ and ‘Sustainable Cities’

The scholarly literature emphasizes the pivotal roles of infrastructure, service delivery, governance, and digital transformation, in shaping ‘sustainable’ and ‘smart cities’ [70,71]. The United Nations (2018) [72] underscores infrastructure as crucial for economic growth and improved urban quality of life, emphasizing its role in minimizing environmental impact and enhancing resilience against climate change [73].
Given the importance of efficient service delivery, emphasizing its impact on citizen satisfaction and social equity within urban areas has been highlighted [74,75,76]. Governance plays a critical role in sustainable urban development [77,78,79,80] with stakeholder engagement, adaptive management, and collaborative decision-making contributing to resilient and sustainable cities [81].
The realm of digital transformation is increasingly acknowledged as a catalyst for sustainability in cities [81,82,83,84]. Meng et al. (2023) emphasize digitalization competitiveness and enhanced productivity [85]. Nam and Pardo (2011) highlighted how digital transformation optimizes resource utilization, enhances connectivity, and augments the overall efficiency of urban systems [86]. The holistic integration of these elements proves indispensable in the pursuit of sustainable urban development [12].
Similarly, the literature consistently affirms that infrastructure, service delivery, governance, and digital transformation collaboratively shape smart cities, fostering innovation and efficiency [70,71,72,73,74,75,76,77,78,79,80]. Infrastructure is a linchpin, facilitating advanced technology deployment [70,71,83], while well-designed infrastructure is integral for seamless connectivity and smart solutions integration [50]. Service delivery optimization through technology is highlighted in smart cities [87] enhancing the experience of city inhabitants [86]. Effective governance is pivotal for smart cities’ success [9,88], with collaboration and data-driven decision-making playing a crucial role in realizing smart city initiatives [89,90]. Digital transformation, which leverages technology, is at the core of smart cities [83,90], transforming cities into dynamic and responsive environments [19]. These interconnected elements substantiate the multifaceted approach essential for the development and sustenance of smart cities.
Therefore, well-planned, designed, and efficient infrastructure, as well as optimized service delivery, proficient governance, and innovative digital solutions are indispensable for developing both ‘smart’ and ‘sustainable’ cities [12] and consequently smart sustainable cities.
The diverse elements related to infrastructure, service delivery, governance, and digital transformation influencing smart sustainable cities as adapted from the United for Smart Sustainable Cities (U4SSC) Key Performance Indicators (KPIs) project [91] are presented in Table 2. The amalgamation of these elements collectively propels environmental sustainability, economic prosperity, and an improved quality of life in urban areas. Therefore, in this study, a synergistic integration, emphasizing a harmonious approach to creating smart sustainable cities, is theorized.

5. Interconnectedness and Symbiotic Relationships between the Four Aspects—Infrastructure, Service Delivery, Governance, and Digital Transformation

The linkage and symbiotic relationship among the four pivotal aspects are explored in the following sections. Figure 3 presents the conceptualized symbiotic relationship among the four facets of smart sustainable cities with digital transformation serving as a catalyst. Each of these dimensions engages in reciprocal cause-and-effect or feedback relationships, fostering mutual enhancement and higher efficiency. Furthermore, the synergy of digital transformation and the optimized utilization of ICT serves as a dynamic catalyst, propelling the augmentation of the three aspects—infrastructure, service delivery, and governance. The symbiotic relationships among these aspects are presented in the following subsections.

5.1. Digital Transformation and Infrastructure

5.1.1. Defining Digital Transformation and Its Significance

Digital transformation encompasses the seamless integration of digital technologies, primarily ICT, Internet of Things (IoT), and AI, into an organization’s operational framework. This integration fundamentally transforms how the organization delivers value to its stakeholders, customers, and employees [92,93]. While ICT and IoT have been extensively employed in city functions with evident success, the adoption of AI has been more recent. The advancements in AI are ushering in autonomous technologies for city management, heralding the advent of autonomous cities. These spaces, born out of years of experimentation with eco and smart-city concepts, witness diverse artificial intelligence, ranging from service robots to digital platforms, orchestrating urban activities traditionally performed by humans.
Evidence suggests that AI-enabled smart cities offer various benefits, including enhanced efficiency and performance, better risk identification and monitoring, improved economic prospects, streamlined data and information processing, enhanced service delivery, more informed decision-making, increased engagement and interaction, and greater sustainability. However, alongside these benefits come challenges related to data management, organizational and managerial adaptation, skill acquisition, interpretation of AI outputs, ethical considerations, legitimacy concerns, political dynamics, legal frameworks, policy formulation, social and societal implications, and economic ramifications [94].
Despite the challenges, the transformative process utilizes technology to optimize internal processes, enhance decision-making capabilities, improve customer experiences, and drive innovation [95,96,97]. The impact of digital transformation is particularly evident in many spheres of society and infrastructure. For example, in the government sector, the adoption of digital tools and online platforms enhances service delivery, streamlining processes and improving accessibility. Data analytics play a crucial role in informed decision-making, performance monitoring, and resource allocation, contributing to enhanced policy development and implementation [98,99]. Initiatives like e-government and open data platforms further reinforce transparency and accountability in governmental processes, transforming organizational culture [100,101].
Similarly, in healthcare, digital transformation revolutionizes patient care through technologies such as electronic health records, telemedicine, and remote patient monitoring [92,93,94]. This not only improves the coordination of care but also enables timely interventions, ultimately enhancing patient outcomes. Operational efficiency is achieved through streamlined data management and the implementation of data analytics, leading to cost reduction and optimized resource allocation. Additionally, the integration of AI and machine learning (ML) supports research, diagnostics, and personalized treatment plans, fostering innovation [102,103,104].
In the education sector, digital tools including AI and online platforms create personalized learning experiences, enhancing engagement and accessibility [105,106,107]. Administrative processes, ranging from enrolment to grading, are streamlined, enabling educational institutions to allocate resources effectively and focus on improving educational outcomes. Digital transformation in education also facilitates global collaboration and connectivity, allowing students to engage with international peers, access educational resources worldwide, and participate in collaborative projects [106,107,108].
Thus, the overarching impact of digital transformation is manifested in its ability to enhance efficiency, improve services, foster innovation, and increase connectivity across diverse sectors. Embracing digital technologies is imperative for organizations and consequently, the cities to remain competitive, respond to evolving demands, and better serve their stakeholders and society.

5.1.2. Influence of Digitalization on the Development of Physical and Virtual Infrastructure

Öhman (2010) [109] and Ablyazov (2021) [110] underscore the societal and material facets of infrastructure, highlighting its role in shaping spatial localizations and influencing various socioeconomic factors, which was also supported by several other scholars [111,112,113,114]. Digital technology has broken the physical barrier and become a pervasive presence across space and time. Ablyazov (2021) [110] suggests using Internet of Things (IoT) technology to overcome barriers to digital transformation, enabling the intricate integration of physical and digital urban infrastructure.
In the context of physical infrastructure, digitalization integrates smart technologies with infrastructure to make them smart and efficient. For example, it assists in creating smart grids for optimizing energy distribution and efficient traffic management systems [115]. Similarly, IoT plays a crucial role by providing real-time data through embedded sensors for predictive maintenance and lifespan extension of the physical infrastructure. The concept of digital twins has also emerged, creating virtual replicas for real-time monitoring and simulation, enhancing decision-making and proactive maintenance [111,112,113,114,116].
In the virtual infrastructure domain, digitalization drives the widespread adoption of cloud computing, creating a flexible and scalable virtual environment [117]. Massive data centers, a product of digitalization’s growth, serve as the backbone of virtual infrastructure, supporting the global-scale deployment of applications and services. Digitalization also leads to the development of software-defined infrastructure and AI, abstracting hardware functionalities into software for enhanced adaptability and scalability. The rise of digitalization facilitates the development of virtual networks, exemplified by the expansion of 5G networks, which provide high-speed and low-latency connectivity for various applications [117,118]. However, the increasing reliance on virtual infrastructure necessitates robust cybersecurity measures to protect virtual assets, sensitive data, and critical systems.
The integration of digital technologies including AI transforms both physical and virtual infrastructure, enhancing efficiency, resilience, and adaptability, aligning with the demands of modern society and the dynamic forces embedded in economic structures. This transformative evolution shapes the interconnected and intelligent world in which the systems are built, operated, and interact with infrastructure [109,110,111].

5.1.3. Digital Technologies for Optimizing Infrastructure Planning, Construction, and Maintenance

Digital technologies play a crucial role in enhancing infrastructure planning, construction, and maintenance, yielding efficiencies, cost reductions, and improved decision-making throughout the project lifecycle [12,83]. In the planning phase, data analytics tools, such as Geographic Information Systems (GIS), Augmented/Virtual Reality, etc., aid informed decision-making for optimal project location and design [115,116]. Predictive analytics forecasts future infrastructure needs, valuable in urban planning for accommodating evolving demands. Simulation and modelling tools empower planners to conduct simulations on various aspects such as traffic movement, environmental impact assessments, structural analyses, and more. These tools help in identifying challenges and optimizing designs for enhanced efficiency and effectiveness. Public engagement is enhanced through digital technologies such as virtual reality (VR) and augmented reality (AR), allowing stakeholders to visualize projects, provide feedback, and participate in decision-making [115,119,120]. In construction, Building Information Modelling (BIM) aids collaboration, coordination, and error reduction [115]. Drones and Unmanned Aerial Vehicles (UAVs) assist in optimizing resource allocation, provide real-time aerial surveys and monitoring sites and enhance safety [121].
Furthermore, digital technologies, including IoT and data analytics, enable monitoring infrastructure conditions in real-time, identifying potential issues before they become critical and extending asset lifespan [122]. Remote monitoring and control enable maintenance teams to detect faults and perform diagnostics without physical inspection. Asset management systems provide a centralized platform for tracking and managing infrastructure assets, including maintenance history, replacement schedules, and overall health. Augmented Reality (AR) applications assist maintenance teams by overlaying digital information onto the physical environment, enabling visualization of repair instructions, schematics, and data during tasks [122,123,124,125].
Similarly, AI holds significant potential for enhancing infrastructure across various sectors including energy, water, wastewater, transport, and telecommunications. It can not only facilitate but also bring agility and efficiency in forecasting, routing, maintenance, security, network quality management, etc. [111]. With its data-driven approach and inherent flexibility, AI can effectively address challenges across different network sizes and geographical scales.
Thus, digital transformation contributes to a more efficient, sustainable, and resilient infrastructure development and management, empowering people and decision-makers to meet societal demands.

5.2. Infrastructure and Service Delivery

5.2.1. Relationship between Robust Infrastructure and Effective Service Delivery

The nexus between robust infrastructure and effective service delivery is crucial for societal and organizational advancement [126]. It forms the foundation for reliable provision across various services for example electricity, education, healthcare, water supply, etc. [126,127].
