The construction of green and smart cities is an important approach to enhancing the level of high-quality development and modern governance, in which infrastructure construction is the antecedent condition. From the perspective of green total factor productivity (GTFP), this paper adopts the SBM–GML (Slack-Based Model and Global Malmquist–Luenberger) index to measure the urban green and smart development level (GSDL) considering smart input–output factors. Based on the panel data of China’s 223 prefecture-level cities from 2005 to 2018, the dynamic impacts, temporal, and spatial differences of energy, transportation, and telecommunication infrastructure construction on the urban GSDL are discussed, and the threshold effects of urban scale are tested. The following conclusions are drawn: (1) On the whole, energy infrastructure inhibits the urban GSDL, while transportation and telecommunication infrastructures significantly promote it. There are distinct spatial and temporal characteristics among the impacts of these three infrastructures on the urban GSDL, in which the facilitating role of transportation and telecommunication infrastructures are further enhanced during the period of 2013–2018. Furthermore, the impacts of these three infrastructures on the urban GSDL all show “U” shape in terms of non-linearity. (2) Economic development level and industrial structure have significant positive effects on the urban GSDL, whereas human capital only has positive effect in the northeast and southwest regions, and government scale shows no positive impact yet. (3) There is a single threshold for the impact of urban scale on these three infrastructures, among which the impacts of energy and transportation infrastructures on the urban GSDL remain consistent before and after the threshold, while the impact of telecommunication infrastructure on the urban GSDL varies from having no significance to being positive when crossing the threshold. Thus, capital investment for infrastructure construction should be further allocated reasonably, the positive potential of human capital should be fully released, and the urban scale should be appropriately controlled in the future.

Texto completo da fonteResumo:
Of the build out of humanity predicted up to the end of the century, a substantial portion will occur within informal urban settlements – areas characterised by poor access to infrastructure and services. There is a pressing need to better understand how and with what implications the growing proliferation of Internet of Things (IoT) technologies, as a component of smart urbanism, are being applied to address the challenges of these areas. The following paper addresses this research gap, showing how IoT technology is reconfiguring trust within water and energy infrastructures in Nairobi. We apply work on informal urban infrastructures and smart urbanism to three case studies, producing novel insights into how IoT technologies reconfigure connections between users, providers and infrastructures. This reconfiguration of trust smooths chronic infrastructural uncertainties and generates reliability within informal settlements and, in doing so, leads to increased personal economies. We conclude by considering how these examples provide insights into the implications of IoT for everyday urbanisms in informal settlements and how these insights relate to global smart city debates more widely.

Texto completo da fonteResumo:
Over the last few years, nexus-thinking has become a buzzword in urban research and practice. This also applies to recent claims of greater integration or coordination of urban infrastructures that have traditionally been managed separately and have been unbundled. The idea is to better address their growing sociotechnical complexity, their externalities and their operation within an urban system of systems. This article introduces a collection of case studies aimed at critically appraising how concepts of nexus and infrastructure integration have become guiding visions for the development of green, resilient or smart cities. It assesses how concepts of nexus and calls for higher interconnectivity and ‘co-management’ within and across infrastructure domains often forestall more politically informed discussions and downplay potential risks and institutional restrictions. Based on an urban political and sociotechnical approach, the introduction to this special issue centres around four major research gaps: 1) the tensions between calls for infrastructure re-bundling and the urban trends and realities driven by infrastructure restructuring since the 1990s; 2) the existing boundary work in cities and urban stakeholders’ practices in bringing fragmented urban infrastructures together; 3) the politics involved in infrastructural and urban change and in aligning urban infrastructures that often defy managerial rhetoric of resource efficiency, smartness and resilience; and 4) the spatialities at play in infrastructural reconfigurations that selectively promote specific spaces and scales of metabolic autonomy, system operation (and failure), networked interconnectivities and system regulation. We conclude by outlining directions for future research.

Texto completo da fonteResumo:
This article explores a tension between financialisation of electricity infrastructures and efforts to bring critical urban systems into common ownership. Focusing on the emerging landscape of electricity regulation and e-mobility in the United Kingdom (UK), it examines how electricity grid ownership has become financialised, and why the economic assumptions that enabled this financialisation are being called into question. New technologies, such as smart electricity meters and electric vehicles, provide cities with new tools to tackle poor air quality and greenhouse gas emissions. Electricity grids are key enabling infrastructures but the companies that run them do not get rewarded for improving air quality or tackling climate change. UK government regulation of electricity grids both enables financialisation and forecloses opportunities to manage the infrastructure for wider environmental and public benefit. Nonetheless, the addition of smart devices to this network – the ‘smart grid’ – opens up an opportunity for common ownership of the infrastructure. Transforming the smart grid into commons necessitates deep structural reform to the entire architecture of infrastructure regulation in the UK.

The study aims to enhance interactions within smart city infrastructures by systematically analyzing associated challenges and proposing strategic solutions. Employing methodologies such as system analysis, synthesis, optimization, modeling, and decision-making—while considering process uncertainties—we dissect the "smart city" and "smart city dweller" concepts, charting their evolutionary cycles. The results outline a structural framework for interactions between citizens, the state, businesses, and society, integrating key subsystems into a unified infrastructure. We also evaluate feedback mechanisms in urban projects like "Active Citizen" and "Garbage. Not.Net," and investigate smart city self-regulation using the Hurwitz criterion. These insights provide actionable guidance for assessing and advancing smart city projects.

Texto completo da fonteResumo:
Abstract This article aims to understand contemporary forms of “digital work” and how this is imagined in visionary documents in the context of smart urbanism. Specifically, we argue for an infrastructural perspective on smart urbanism to highlight (1) how such visionary documents organize society in specific ways and (2) how this organization is rooted in work that is imagined as being mainly informational and disembodied. Through an analysis of Singapore’s recent Smart Nation initiative, we make a case for the inclusion of the actual human and embodied work that constitutes visions of smart urbanism. This work comprises both the physical construction and maintenance of digital infrastructure and the monitoring of these infrastructures and the interpretation of data on which they run. Finally, we show how an infrastructural inversion of smart urban initiatives is capable of highlighting these invisibilities of human work, specifically by drawing on the mundanity, temporality, and materiality of work that is considered digital.

Texto completo da fonteResumo:
Electrical power systems are crucial, yet vulnerable, due to their complex and interconnected nature, necessitating effective fault detection and diagnostics to ensure stability and prevent disruptions. Advances in artificial intelligence (AI) and the Internet of Things (IoT) have transformed the ability to identify and resolve electrical system problems efficiently. Electrical systems operate at various scales, ranging from individual households to large-scale regional grids. In this study, we focus on medium-scale urban infrastructures. These environments present unique electrical challenges, such as phase imbalances and transient voltage fluctuations, which require robust fault detection mechanisms. This work investigates the use of AI with dynamic programming and a support vector machine (SVM) to improve fault detection. The data collected from voltage measurements in urban office buildings with smart meters over a period of six weeks was used to develop an AI model, demonstrating its applicability to similar urban infrastructures. This model achieved high accuracy in detecting system failures, identifying them with a performance greater than 99%, highlighting the potential of smart sensing technologies combined with AI to improve urban infrastructure management. The integration of smart sensors and advanced data analytics significantly increases the reliability and efficiency of energy systems, promoting sustainable and resilient urban environments.

Texto completo da fonteResumo:
The convergence of networked digital infrastructures and built environments have given rise to the "urban user", a conflation of "the user" and "the resident" or "the citizen". The urban user and the city infrastructures are mutually constituted phenomena formed through the interactions between them. In this research, we contribute an ethnographic study that focuses on the everyday interactions between the urban user and water infrastructures in Pune, India. Using Nikhil Anand's concept of "hydraulic citizenship" to analyze our ethnographic data, we showcase the mutually constitutive process of infrastructuring and subjectivization of the "citizen", bringing attention to the ad hoc, heterogeneously constituted water infrastructures in Pune that aspire to be "smart" even before becoming functional infrastructures. In doing so, we hope to expand possible research trajectories within smart city research agendas by decoupling it from Western assumptions and also by linking them to an interactional account of the everyday relationships among residents, infrastructures, and municipalities.

Texto completo da fonteResumo:
Smart city is a major discussion in metropolitan planning and governance as it involves using technology to create livable spaces for the present and the future; it also considers issues of mobility, governance, economy and energy production. The innovation of smart city initiative can be beneficial to urban planning and policies for house provision. The housing challenge is a prominent issue in Lagos, the economic capital of Nigeria with more than 20 million inhabitants. Despite the attempts by the Lagos state government to create low-cost housing for citizens living and working in the city, there are still enormously high housing deficits because of the city’s overpopulation and limited resources. The city still lacks adequate infrastructures for mobility, networking and affordable housing as some people come from other states to work in the state; this has increased the urban carbon emissions. Yet, emerging discourses on housing infrastructure have rarely engaged the smart city question in urban governance of Lagos. Although there is a plethora of literature interrogating urbanization processes and housing, there are feeble attempts at explaining the notion of the smart city as the panacea for infrastructural inadequacies and urban development. This research examines the concept of smart city and its implication for urban governance structures and affordable housing in Lagos, drawing information and data from interviews and relevant secondary sources. The relevance of this study is to the government, private sector and architectural community is formulating policies through the application of the smart city concept in a megacity in a developing country like Lagos.

Texto completo da fonteResumo:
The design and operation of multifunctional infrastructures for public lighting as well as their impact on the urban environment and citizens’ life is today of great interest. The cost of energy for public lighting is often an issue for the budget of municipalities. Furthermore, researchers’ and designers’ attention is increasingly focused on aspects of public lighting not directly valuable through economic factors. Starting from the “quality” of the light environment, looking at citizens’ visual comfort, the light has to be considered as an instrument to improve the urban context and objects therein (including buildings). Indeed, urban degradation (lack of infrastructures, maintenance, services, etc.) is linked to the poor quality of everyday issues, such as traffic, pollution, noise, lack of information, long times to access focal points, and the lack of safety. Simultaneously, in many areas, the potential related to the valorization of historical heritage is often underexploited. The installation of efficient lighting systems coupled with the implementation of ICT solutions can provide economic, social, and health benefits, energy efficiency, and visual comfort. On the other hand, as for indoor lighting, these systems can be expensive, not easy to maintain, and not as efficient as expected. The aim of this Special Issue was to investigate the problems and advantages of smart urban lighting systems in more detail. This Special Issue included 6 papers of the 10 submitted papers.

Smart cities are being actively adopted in major cities to address urban issues and secure growth drivers for the Fourth Industrial Revolution. However, former research had focused on the technological aspects of smart cities or discussions related to user perceptions, lacking comprehensive discussions that consider socio-cultural and institutional characteristics. This study aims to analyze Smart Pole as one of the most crucial infrastructures in smart cities, to identify key factors for successful adoption and utilization, and to explore strategic approaches. To this purpose, we employed a Socio-Technical Systems(STS) approach. We analyzed Seoul and Gangwon Province cases comparatively. As a result, this study confirmed the need for a systematic strategy that integrates urban characteristics, citizens' cultural background, and demand to install Smart Poles appropriate to the urban environment. This study contributes by expanding STS theory and confirming the significance of considering socio-cultural contexts in establishing strategies for the adoption of new ICT infrastructures such as Smart Pole.

Texto completo da fonteResumo:
The article is devoted to cybersecurity risk assessment of the dynamic device-to-device networks of a smart city. Analysis of the modern security threats at the IoT/IIoT, VANET, and WSN inter-device infrastructures demonstrates that the main concern is a set of network security threats targeted at the functional sustainability of smart urban infrastructure, the most common use case of smart networks. As a result of our study, systematization of the existing cybersecurity risk assessment methods has been provided. Expert-based risk assessment and active human participation cannot be provided for the huge, complex, and permanently changing digital environment of the smart city. The methods of scenario analysis and functional analysis are specific to industrial risk management and are hardly adaptable to solving cybersecurity tasks. The statistical risk evaluation methods force us to collect statistical data for the calculation of the security indicators for the self-organizing networks, and the accuracy of this method depends on the number of calculating iterations. In our work, we have proposed a new approach for cybersecurity risk management based on object typing, data mining, and quantitative risk assessment for the smart city infrastructure. The experimental study has shown us that the artificial neural network allows us to automatically, unambiguously, and reasonably assess the cyber risk for various object types in the dynamic digital infrastructures of the smart city.

Texto completo da fonteResumo:
The generation and supply of electricity is currently about to undergo a fundamental transition that includes extensive development of smart grids. Smart grids are huge and complex networks consisting of a vast number of devices and entities which are connected with each other. This opens new variations of disruption scenarios which can increase the vulnerability of a power distribution network. However, the network topology of a smart grid has significant effects on urban resilience particularly referring to the adequate provision of infrastructures. Thus, topology massively codetermines the degree of urban resilience, i.e. different topologies enable different strategies of power distribution. Therefore, this article introduces a concept of criticality adapted to a power system relying on an advanced metering infrastructure. The authors propose a two-stage operationalization of this concept that refers to the design phase of a smart grid and its operation mode, targeting at an urban resilient power flow during power shortage.

Spatial Data Infrastructure (SDI) has become important in developing Smart Cities initiatives to incorporates different types of spatial data, sensors, and technologies to optimise services for residents, via leveraging technological advancements across various fields. SDI support the to enable spatial data availability and access. However, integrating SDI into smart city development faces challenges due to a lack of standardized practices, technical interoperability issues, and diverse data governance policies among cities. These challenges hinder policymakers from effectively using spatial data to enhance urban services and sustainability. To address these issues, a comprehensive review is needed to propose strategies for the successful integration of SDIs into smart city initiatives. This study aims to review current developments in SDI integration within Smart City initiatives, identify key areas of focus, and suggest future directions for improvement. This study uses comparative analysis to synthesize the issues, challenges, findings, and future directions in integrating SDI-Smart Cities initiatives. The review identifies issues related to spatial data integration, technology compatibility, data management, metadata analysis, and institutional frameworks. Improvements in integrating SDI-Smart City initiatives can be directed towards spatial data integration, technological advancements, and institutional reforms. This study highlights the importance of SDI integration in Smart City development by providing a robust spatial data foundation, contributing to sustainable urban growth.

Texto completo da fonteResumo:
Urban integration (UI) has emerged as the guiding maxim for enabling efficient resource flows and smart and connected cites. The last decade has led to renewed interest in exploiting interconnections to optimise city capacities in urban policy, practice and research. However, the imperative for integration across resources, infrastructures, sectors and disciplines remains largely unquestioned, and its socio-political and environmental implications receive little critical attention. This paper subjects the ideas and practices of UI to scrutiny. We argue that integration-in-practice (as opposed to integration-in-theory) is partial and selective in its objects of combination and outcomes. The key issue this raises is whether the promise of new metropolitan-wide imaginaries of horizontal integration gives way to more selective logics of vertical integration that privilege socially and spatially valued enclaves. Rather than challenge urban splintering, UI practices would therefore reinforce urban infrastructure divides. The paper argues that a subtle shift is taking place in the UI discourse that whilst promising resource sustainability and metropolitan inclusivity, re-prioritises and re-intensifies more selective infrastructural planning processes. We term this new emerging mode bifurcated urban integration (BUI).

Texto completo da fonteResumo:
With cities rapidly advancing technologically, the rise of smart cities brings innovative solutions to urban challenges. However, this integration of technologies within urban infrastructures introduces new cybersecurity risks. This review explores the cybersecurity issues that smart cities face and discusses strategies to address these threats. Smart cities rely on interconnected networks of devices and systems to enhance efficiency, sustainability, and citizen services. Yet, this connectivity also creates a complex environment that is vulnerable to cyberattacks. A key concern is the wide array of IoT devices deployed across smart city infrastructures, which often lack robust security mechanisms, making them susceptible to exploitation by cybercriminals. The interconnected nature of these systems heightens the potential impact of cyberattacks, posing significant risks to critical infrastructure, public safety, and privacy. Threat actors can exploit vulnerabilities in interconnected systems, disrupting essential services, manipulating data, or even causing physical harm. Since smart cities heavily depend on data-driven decision-making, ensuring data integrity and confidentiality is a top priority. To mitigate these risks, various cybersecurity strategies have been proposed and implemented. These include technical solutions, regulatory frameworks, and collaboration among stakeholders. Technical measures like encryption, authentication mechanisms, intrusion detection systems, and secure software development practices are essential. Additionally, strong access controls and network segmentation can limit the scope of potential attacks. Regulatory initiatives also play a crucial role in improving cybersecurity standards and ensuring compliance among stakeholders. Establishing clear guidelines for data protection, privacy rights, and incident response protocols is vital for safeguarding citizens' interests. Collaborative efforts between government agencies, the private sector, academia, and cybersecurity experts are crucial in sharing information and collectively defending against emerging threats. Securing smart cities requires a comprehensive approach that integrates technical measures, regulatory frameworks, and collaborative efforts to create a resilient and secure urban environment for all citizens.

The evolution of smart cities has ushered in a new era of sustainable urban living, with energy management at its core. This paper offers a comprehensive review of the energy-related planning and operational models within the smart city framework, categorizing them into five primary intervention areas: generation, storage, infrastructure, facilities, and transport. The intricate relationship between smart cities and electric vehicles (EVs) is explored, emphasizing the need for robust charging infrastructures and forecasting peak loads. As the adoption of EVs surges, challenges such as power grid strain, voltage fluctuations, and power losses become more pronounced. Innovative solutions leveraging machine learning, including techniques like LSTM, DNN, and SVM, have been proposed to manage EV charging, ensuring efficiency and minimizing costs. Furthermore, the integration of EVs into smart cities is not without its challenges. Beyond the technical aspects, economic, social, and environmental challenges arise, necessitating a holistic approach for seamless integration. This review underscores the importance of a multifaceted strategy, encompassing all aspects of EV integration, to realize the vision of truly sustainable and smart urban centres.

The integration of infrastructure domains and resource flows such as electricity, heat, water and waste increasingly gains currency in strategies to achieve more resource-efficient, smart and resilient cities. While widely discussed concepts of a nexus of resource systems, such as energy–water–food, aim at a more optimised and integrative management of resource flows, this article investigates how infrastructure integration is accomplished through the establishment of new interfaces and junctions between formerly separated systems. In particular, it focuses on households as an arena where different urban infrastructures intersect and different kinds of sometimes contradicting demands are imposed to co-manage these infrastructures, such as in the case of own electricity generation from photovoltaics along with the charging of electric cars and the management of household energy consumption. The installation of meters and the constant monitoring of resource use and consumption feedback to household members is regarded as a crucial element in such a transition towards more sustainable urban infrastructures. Empirically, the article studies the introduction of hot tap water meters in urban households in Sweden and the resistance and reactions of these households to such a metering regime. Our study shows how meters as new junctions between energy suppliers and users but also between separate infrastructures of electricity, hot tap water and room heating become contested political terrains which are linked to broader socio-political questions of urban change. In contrast to system management perspectives, such an ‘inside-out’ approach rather lends itself to context-sensitive and navigational governance approaches of infrastructure integration.

Public spaces play a significant role in improving social, recreational and cultural activities that are inclusive. However, smart public spaces are required to save time and costs, and to provide comfort to the public, ultimately enhancing livability. There are various user requirements and demands to respond to. This research aims to adopt intelligent technologies applied in public spaces to facilitate livability through urban facility management (UFM) involvement in improving livability. The establishment of intelligent systems in the architecture industry goes hand in hand with the growing advancement of science and technology in several aspects of human life. A fundamental key to the success of smart cities is the high quality of livability offered to their residents and visitors. The UFM can enable livability by providing data centers, access controls, integrated security systems, monitoring, smart waste, energy and water management in public spaces. This study focused on five elements of livability, including accessibility, functional infrastructure, interaction and social cohesion, amenity and participation, quality of life through safety and security and privacy. The research methodology adopts the activity theory (AT) as its underpinning theory for the qualitative data collection process (interviews and a workshop) from industry experts in two prominent smart cities in Qatar, Lusail and Msheireb, along with a literature review. This study’s results provide information on existing smart city and public space features, infrastructures and their impact on livability. The findings of this study support the development of the smart livable public spaces (SLiPS) framework. The framework is a baseline for improving livability in smart cities, which allows future updates based on existing ICT infrastructure, enabling new functions and the availability of novel technology applied by UFM. The outcome of livability leads to the achievement of smart city goals.

The “smart city” has risen to global prominence over the past two decades as an urban planning and development strategy. As a broad but contested toolkit of technological services and policy interventions aimed at improving the efficacy and efficiency of urban systems, the “smart city” is subject to several pressing critiques. This paper acknowledges these concerns, but recognizes the potential of “urban intelligence” to enhance the resiliency of metropolitan areas. As such, we focus on an under-researched dimension of smart city urbanism: its application in peripheral urban areas. The paper introduces a threefold typology of: (a) geographic (spatial); (b) hard (material); and (c) soft (social) urban peripherality. Second, it reviews the concept of urban resilience and considers how its central characteristics can inform the objectives and implementation of “smart city” infrastructures and planning. Six European smart city plans are assessed via a qualitative content analysis, to identify the target of smart city actions; the characteristics of urban resilience mobilized; and the spatial focus of planned interventions. The comparative analysis reveals a variegated set of smart-city approaches. Notably, “smart” actions aimed at enhancing social innovation are the most common type of intervention, while overall there remains a strong tendency for smart urbanism to focus on the urban core. We conclude by calling for a research agenda addressing smartness in, of, and for, peripheral urban spaces and communities.

Several developed countries have implemented smart systems for public transport that provide mobility services for citizens. Most of these systems use special infrastructures to determine the location of citizens and public buses. However, the implementation of these systems does not take into account the poor infrastructure of developing countries. In Mexico, Urban Passenger Transport has insufficient transport units to meet the demand of passengers who move throughout the day, and these do not consider hardware infrastructure. Our solution is focused on inexpensive devices that are accessible to citizens, such as mobile phones. In this research work, a smart information system for passengers of urban transport is presented that allows passengers to know the expected arrival times and also to know the availability of seats on the bus that is heading towards their position. The solution was evaluated with real routes, and the results are promising for a pilot project to be put in practice.

This paper summarizes the lessons learned after several decades of exploring and applying Structural Health Monitoring (SHM) in operating bridge structures. The challenges in real-time imaging and processing of large amounts of sensor data at various bandwidths, synchronization, quality check and archival, and most importantly, the interpretation of the structural condition, performance, and health are necessary for effective applications of SHM to major bridges and other infrastructures. Writers note that such SHM applications have served as the forerunners of cyber infrastructures, which are now recognized as the key to smart infrastructures and smart cities. Continued explorations of SHM in conjunction with control, therefore, remain vital for assuring satisfactory infrastructure system performance at the operational, damageability, and safety limit-states in the future. Researchers in the SHM of actually constructed systems, given their experience in monitoring major structures in the field, are well positioned to contribute to these vital needs. Especially, SHM researchers who have learned how to integrate the contributions from various disciplines such as civil, electrical, mechanical, and materials engineering; computer and social sciences; and architecture and urban planning would appear to be well equipped and could become instrumental in assessing the health and performance of urban regions, which today must function by optimizing and balancing the needs of Livability, Sustainability, and Resilience (LSR).

Abstract Smart metering and data analytics enable the implementation of a range of on-site infrastructures for energy, water and waste management to demonstrate the interconnected infrastructure of future smart cities. A research project in Western Australia is integrating smart metering technology, household participation and data analytics. An improved understanding of hybrid water systems at residential scale, as socially accepted solutions to promote water efficiency and economic savings, within the traditional centralized urban water network is achieved. An integrated water model and a system of water credits and debits are developed and tested on a case study for which 10-minute logged water consumption data of its hybrid water system are available for 1 year. The model is shown to provide a full characterization of the relationship between the household and the water resources, thus assisting with improved urban water management which promotes the rollout of decentralized hybrid water systems whilst accounting for the impacts on the aquifer as an ecosystem service provider.

For many centuries, the principle of linear planning based on a grid pattern has played a significant role in the spatial organization of urban boundaries. Additionally, the grid principle has formed the basis for policies and practices related to the emergence of “disciplinary societies”, leading to the modern networked society. Drawing on the concept of the grid as a cultural technique by media philosopher Bernhard Siegert, this article examines the functioning of the grid as epistemic frameworks and the media of representation, order, and filteration. The article also provides insights into the manifestation of the grid principle in the context of the emerging field of social research on infrastructures, including the digital infrastructure of smart cities. This encompasses a wide spectrum, from smart devices and everyday communication to pervasive sensors and big data, from the sharing of images and impressions to advanced prosthetics, from the development of smart cities to the deployment of surveillance technologies and predictive algorithms. Through a range of case studies, from the study of structured territorial control of the Roman limitatio to the efficient grid patterns of pre-fabricated housing districts worldwide, the research examines the potential and transhistorical nature of the grid principle. The article is intended for media philosophers, anthropologists, urbanists and digital culture theorists.

Texto completo da fonteResumo:
The scale of human accidents and the resultant damage has increased due to recent large-scale urban (building) fires, meaning there is a need to devise an effective strategy for urban disasters. In the event of a fire, it is difficult to evacuate in the early stages due to the loss of detection function, difficulty in securing visibility, and confusion over evacuation routes. Accordingly, for rapid evacuation and rescue, it is necessary to build a city-level fire safety service and digital system based on smart technology. In addition, both forest and building fires emit a large amount of carbon dioxide, which is the main cause of global warming. Therefore, we need to prepare both energy and fire management to achieve carbon neutrality by 2030. In this study, we developed an AI-based smart fire safety system for efficient urban integrated management using a city-based fire safety architecture. In addition, we designed a fire management infrastructure and an energy management system for buildings. The proposal was demonstrated by building a test bed in the A building, and the AR-based mobile/web application was tested for optimized evacuation management. Furthermore, AI-based fire detection and the optimal evacuation of occupants were implemented through deep learning-based fire information data analysis. As a result, this paper presents four points for safety and energy management, and we demonstrate that the optimization of occupant evacuation ability and energy saving can be achieved. We also analyze the efficiency of the data transfer rate to prevent data communication delays by using Virtual Edge Gateway (VEG) management. In the future, we expect that the appearance of future fire and energy management buildings through this research will produce more accurate data prediction technology and the development of cutting-edge smart technology in smart city infrastructures.

Datafication has become a prominent feature of smart cities, where sensors, monitoring devices, and AI are being integrated with city infrastructures and facilities, resulting in rapidly changing urban areas informed by data-driven decision-making processes. Although there is a vast amount of data being generated about urban environments and citizens, research on understanding citizens’ social experience in smart cities has been limited. This study proposes a three-stage research design that provides datafication solutions to understand citizens’ experience of urban environment in a synergistic manner. We employ a mixed methods approach drawing upon multiple data collected by the researcher, from the citizens, and sourced across smart cities open data platforms. It is designed to undertake a place-based and citizen-centric approach to understand the lived social experiences of citizens in urban environments. This work will contribute to our current understanding in developing socially sustainable smart cities, providing methodological insights for future research on how datafication process can be leveraged to improve quality of urban life.

Texto completo da fonteResumo:
Against the backdrop of multiple ongoing crises in European cities related to socio-spatial injustice, inequality and exclusion, we argue for a smart right to the city. There is an urgent need for a thorough account of the entrepreneurial mode of technocapitalist smart urbanism. While much of both affirmative and critical research on Smart City developments equate or even reduce smartness to digital infrastructures, we put actual smartness—in the sense of social justice and sustainability—at centre stage. This paper builds on a fundamental structural critique of (1) the entrepreneurial city (Harvey) and (2) the capitalist city (Lefebvre). Drawing upon Lefebvre’s right to the city as a normative framework, we use Smart City developments in the city of Graz as an illustration of our argument. Considering strategies of waste and mobility management, we reflect on how they operate as spatial and technical fixes—fixing the limits of capitalism’s growth. By serving specific corporate interests, these technocapitalist strategies yet fail to address the underlying structural causes of pressing urban problems and increasing inequalities. With Lefebvre’s ongoing relevant argument for the importance of use value of urban infrastructures as well as his claim that appropriation and participation are essential, we discuss common rights to the city: His framework allows us to envision sustainable and just—actually smart—alternatives: alternatives to technocapitalist entrepreneurial urbanisation. In this respect, a smart right to the city is oriented towards the everyday needs of all inhabitants.

Texto completo da fonteResumo:
Globally emerging smart city concepts aim to make resource production and allocation in urban areas more efficient, and thus more sustainable through new sociotechnical innovations such as smart grids, smart meters, or solar panels. While recent critiques of smart cities have focused on data security, surveillance, or the influence of corporations on urban development, especially with regard to intelligent communication technologies (ICT), issues related to the material basis of smart city technologies and the interlinked resource problems have largely been ignored in the scholarly literature and in urban planning. Such problems pertain to the provision and recovery of critical raw materials (CRM) from anthropogenic sources like scrap metal repositories, which have been intensely studied during the last few years. To address this gap in the urban planning literature, we link urban planning literatures on smart cities with literatures on CRM mining and recovery from scrap metals. We find that underestimating problems related to resource provision and recovery might lead to management and governance challenges in emerging smart cities, which also entail ethical issues. To illustrate these problems, we refer to the smart city energy domain and explore the smart city-CRM-energy nexus from the perspectives of the respective literatures. We show that CRMs are an important foundation for smart city energy applications such as energy production, energy distribution, and energy allocation. Given current trends in smart city emergence, smart city concepts may potentially foster primary extraction of CRMs, which is linked to considerable environmental and health issues. While the problems associated with primary mining have been well-explored in the literature, we also seek to shed light on the potential substitution and recovery of CRMs from anthropogenic raw material deposits as represented by installed digital smart city infrastructures. Our central finding is that the current smart city literature and contemporary urban planning do not address these issues. This leads to the paradox that smart city concepts are supporting the CRM dependencies that they should actually be seeking to overcome. Discussion on this emerging issue between academics and practitioners has nevertheless not taken place. We address these issues and make recommendations.

In modern society, energy conservation is an important consideration for sustainability. The availability of energy-efficient infrastructures and utilities depend on the sustainability of smart cities. The big streaming data generated and collected by smart building devices and systems contain useful information that needs to be used to make timely action and better decisions. The ultimate objective of these procedures is to enhance the city's sustainability and livability. The replacement of decades-old infrastructures, such as underground wiring, steam pipes, transportation tunnels, and high-speed Internet installation, is already a major problem for major urban regions. There are still certain regions in big cities where broadband wireless service is not available. The decision support system is recently acquiring increasing attention in the smart city context. In this article, a deep learning–based sustainable decision support system (DLSDSS) has been proposed for energy building in smart cities. This study proposes the integration of the Internet of Things into smart buildings for energy management, utilizing deep learning methods for sensor information decision making. Building a socially advanced environment aims to enhance city services and urban administration for residents in smart cities using remote sensing techniques. The proposed deep learning methods classify buildings based on energy efficiency. Data gathered from the sensor network to plan smart cities' development include a deep learning algorithm's structural assembly of data. The deep learning algorithm provides decision makers with a model for the big data stream. The numerical results show that the proposed method reduces energy consumption and enhances sensor data accuracy by 97.67% with better decision making in planning smart infrastructures and services. The experimental outcome of the DLSDSS enhances accuracy (97.67%), time complexity (98.7%), data distribution rate (97.1%), energy consumption rate (98.2%), load shedding ratio (95.8%), and energy efficiency (95.4%).

Smart cities are now an established area of technological development and theoretical inquiry. Research on smart cities spans from investigations into its technological infrastructures and design scenarios, to critiques of its proposals for citizenship and sustainability. This article builds on this growing field, while at the same time accounting for expanded urban-sensing practices that take hold through citizen-sensing technologies. Detailing practice-based and participatory research that developed urban-sensing technologies for use in Southeast London, this article considers how the smart city as a large-scale and monolithic version of urban systems breaks down in practice to reveal much different concretizations of sensors, cities, and people. By working through the specific instances where sensor technologies required inventive workarounds to be setup and continue to operate, as well as moments of breakdown and maintenance where sensors required fixes or adjustments, this article argues that urban sensing can produce much different encounters with urban technologies through lived experiences. Rather than propose a “grassroots” approach to the smart city, however, this article instead suggests that the smart city as a figure for urban development be contested and even surpassed by attending to workarounds that account more fully for digital urban practices and technologies as they are formed and situated within urban projects and community initiatives.

Texto completo da fonteResumo:
Over the past decade, much has been written about the potential of smart urbanism to bring about various and lasting forms of betterment. The embedding of digital technologies within urban infrastructures has been well documented, and the efficiencies of smart models of urban governance and management have been lauded. More recently, however, the discourse has been labelled ‘hegemonic’, and accused of developing a view of smart technology that is blinkered by its failure to critique its socio-political effects. By focusing on the case of Singapore’s ‘Smart Nation’ initiative, this paper embraces the paradoxes at the heart of smart urbanism and, in doing so, interrogates the tension between ideology and praxis, efficiency and control, access and choice, and smart governance and smart citizenship. It also demonstrates how such tensions are (re)produced through ‘fourthspace’ – the digitally enabled spaces of urbanism that are co-created, and that contribute to an expansion and diffusion of social and political responsibility. It ends by suggesting how such spaces have the potential to radically transform not just the urban environment, but also the role of government and citizens in designing urban futures.

Abstract. Nowadays, cities need sustainable approaches that take care of the future in order to meet the needs that arise with population activity. Accordingly, for making cities more livable, the necessity of ensuring efficient use of urban sources and planning urban infrastructures brings the smart city concept into the forefront. The smart city solutions are frequently applied by many local governments and stakeholders. For this reason, there is a need to support the collaboration of all relevant actors and to provide a common national strategic perspective among smart city stakeholders. In the Strategic Plan of the Ministry of Environment and Urbanization, the objectives of smart cities and national geographic information services are determined as “to make infrastructure works in order to establish smart cities, to improve the spatial management in cities with the help of technology, to share data to improve public services and to be the focus of national geographical information” and studies on these objectives have been completed. Accordingly, the “2020–2023 National Smart Cities Strategy and Action Plan” has been prepared in order to establish a national strategic view on smart cities and draw a road map under the policy ownership of the Ministry of Environment and Urbanization. By the implementation of this strategy and action plan with the vision of "Livable and Sustainable Cities that Add Value to Life", a new process of transformation and change will be provided to cities that take care of the real needs of citizens, adopting participatory governance by using resources effectively.

Abstract. A city is a complex system and involves many stakeholders with different interests and information about the physical city objects. Information integration from distributed sources is therefore a common challenge in many Smart City projects, as well as in projects for setting up Urban Digital Twins (UDT). In the context of distributed data infrastructures, catalog systems provide a significant contribution to solving the data integration challenge. However, neither existing catalogs for managing urban data nor catalogs used in Spatial Data Infrastructures (SDI) are tailored for managing UDTs. In response to this gap, our research focuses on the development of an extended catalog service including a metadata model specifically designed to manage distributed UDTs. The requirements for the metadata model and the functionality of the catalog were obtained from several smart city projects. As a proof of concept, the paper shows how the catalog implemented on the basis of the CKAN software package is used for managing the UDT of an urban redevelopment project in the city of Munich, Germany.
