The expansion of big data and the evolution of Internet of Things (IoT) technologies have played an important role in the feasibility of smart city initiatives. Big data offer the potential for cities to obtain valuable insights from a large amount of data collected through various sources, and the IoT allows the integration of sensors, radio-frequency identification, and Bluetooth in the real-world environment using highly networked services. The combination of the IoT and big data is an unexplored research area that has brought new and interesting challenges for achieving the goal of future smart cities. These new challenges focus primarily on problems related to business and technology that enable cities to actualize the vision, principles, and requirements of the applications of smart cities by realizing the main smart environment characteristics. In this paper, we describe the state-of-the-art communication technologies and smart-based applications used within the context of smart cities. The visions of big data analytics to support smart cities are discussed by focusing on how big data can fundamentally change urban populations at different levels. Moreover, a future business model of big data for smart cities is proposed, and the business and technological research challenges are identified. This study can serve as a benchmark for researchers and industries for the future progress and development of smart cities in the context of big data. 相似文献

Smart cities employ information and communication technologies to improve: the quality of life for its citizens, the local economy, transport, traffic management, environment, and interaction with government. Due to the relevance of smart cities (also referred using other related terms such as Digital City, Information City, Intelligent City, Knowledge-based City, Ubiquitous City, Wired City) to various stakeholders and the benefits and challenges associated with its implementation, the concept of smart cities has attracted significant attention from researchers within multiple fields, including information systems. This study provides a valuable synthesis of the relevant literature by analysing and discussing the key findings from existing research on issues related to smart cities from an Information Systems perspective. The research analysed and discussed in this study focuses on number of aspects of smart cities: smart mobility, smart living, smart environment, smart citizens, smart government, and smart architecture as well as related technologies and concepts. The discussion also focusses on the alignment of smart cities with the UN sustainable development goals. This comprehensive review offers critical insight to the key underlying research themes within smart cities, highlighting the limitations of current developments and potential future directions. 相似文献

Modern cities currently face numerous challenges related to mobility, waste management, access to resources, etc. Smart Cities integrate information and communication technologies (ICT) to develop innovative solutions that can solve such challenges and create a higher quality of life for their citizens. Two elements need to be considered for smart cities to be successful. First, citizens must participate in the design of the smart city to take advantage of their ideas so that the smart city answers their real needs. Secondly, each city has its own unique characteristics that need to be considered to design a citizen participation strategy truly tailored and adapted to their respective context. In line with these two considerations, the goal of this paper is to identify the context factors that impact citizen participation strategies in smart cities. In order to reach that goal, we performed a qualitative case study of two cities that strive to be smart: Namur (Belgium) and Linköping (Sweden). This analysis allows us to understand how participation is implemented in two different cases and to infer the context factors that impact the respective strategies. Five context-factors have been identified in this study: the smart city consideration, the drivers for participation, the degree of centralization, the legal requirements, and the citizens’ characteristics. By identifying these factors, we can derive context-dependent recommendations about citizen participation for smart cities. These recommendations are then applied to the case of Brussels in Belgium. 相似文献

By now, there have been many standards battles fought within the same industry or by multiple industries in the market-based standardization. In these battles, incompatible standards compete to win market dominance. While there is some research on standards battles found within a single committee, competitions in the committee-based standardization between standards from different committees or SDOs are underexplored. This paper categorizes the types of standards battles by the mode of standardization and the heterogeneity of actors. A new type referred to as ‘committee standards battles for converging systems’ is introduced and the dynamics of such battles is explored with two cases. The battle between the electric vehicle charging and the smart meter communication standard and the battle between two different vehicle-to-everything (V2X) communication standards are analyzed. The failure in achieving compatibility between different committee standards on the same frequency bands results in communication interference that adversely affects the operation of smart systems. Social incompatibilities between actors and alliances from a mix of industries with vested interests towards a particular standard complicate the battling scene. The findings provide implications in terms of heterogeneity, actors, and government role in standards battles. 相似文献

Smart cities are developing at increasing speed. Smart cities rely on the deployment of information and communication technology (ICT) that is digitally transforming our habitats. Digital transformation affects several areas from transportation, energy, government to the environment. But, primarily, it affects citizens. Therefore, the adoption of all areas of the smart city holds great research potential. The purpose of this paper is thus to provide an insight into millennials’ adoption of autonomous vehicles (AV), which are at the forefront of future transport. Millennials are an important focus group for smart city concepts since they are keen to adopt technology and new transport modes. Our research focuses on technology adoption, perception of the benefits, security, safety, mobility-related efficiencies and concerns as the key AV adoption factors. The impact of these factors is empirically tested with structural equation modelling using data from 382 millennials. We confirm the perceived benefits of AV are vital factors for AV adoption whereas the perceived safety of AV significantly reduces the influence of various concerns regarding AV. 相似文献

Although smart service systems have received increasing attention in information systems research, their affordances and constraints processes are less studied. In this study, we draw on interpretive case study methodology and technology affordances and constraints theory to investigate a smart service system use for seaport security in Ghana. With insights from the case of Ghana, we introduce an affordance constraints process as a framework to complement the existing affordance actualisation process framework in information systems. Thus, this study contributes to affordance theory with a new constraints process. The study’s findings show that smart service systems for seaport security afford autonomous access control, real-time security monitoring, and autonomous data capturing for analytics and reporting. However, such affordances can be constrained by power and internet outages, limited storage capacity, and device breakdowns. From these findings, we discuss implications for theory, research, and practice as well as limitations and directions for future research. 相似文献

Smart home technologies (SHTs), such as smart thermostats, are a growing commercial opportunity. SHTs can offer a broad spectrum of potential functional, experiential and esthetic benefits, yet much of the prior research on the adoption of SHTs has been limited by a narrow TAM-based functional view. Relatively little is known about the salient user beliefs related to the experiential and esthetic benefits of SHTs that may affect SHT adoption. To address this gap in research, we conduct a mixed-methods study, wherein we inductively develop a set of factors that reflect salient user considerations associated with smart thermostats and we examine the effects of the elicited factors on the smart thermostat adoption intention. We find that performance expectancy, emphasized by TAM, has a relatively minor effect on the smart thermostat adoption intention and effort expectancy has no effect at all. We identify a novel factor, which we term techno-coolness, as the key predictor of the adoption intention in this context. Techno-coolness is a multidimensional construct that encompasses the perceptions that the technology can make a home look modern and futuristic, can make the user feel technologically advanced, and can be fun to use. Techno-coolness reveals that the technology capacity to fulfill higher-order psychological needs can dominate purely functional considerations in innovative technology adoption decisions. 相似文献

There is a growing body of literature calling for work on the emerging role of smart cities as information hubs and knowledge repositories. This article reviews the existing smart city literature and integrates knowledge management perspectives to provide an overview of future research directions. By demonstrating the multi-stakeholder relationships involved in smart city development, it takes a crucial step towards looking into the role of knowledge management in future smart city research. Eighty-two peer-reviewed publications were analyzed covering smart city studies in various research domains. The systematic review identifies five different themes: strategy and vision, frameworks, enablers and inhibitors, citizen participation, and benefits. These themes form the basis for developing a future research agenda focused on knowledge sharing and co-learning among cities via three research directions: socio-technical approaches, knowledge sharing perspectives and organizational learning capabilities. The paper also proposes a series of knowledge-driven policy recommendations to contribute towards the UN Sustainable Development Goals. 相似文献

Little or no prior work has examined how information technology enables the development of a design centered digital ecosystem. To examine this research question, we employ a capabilities lens and identify the pathways through which IT drives the development of a design centric smart tourism ecosystem. We analyzed archival data and data collected from interviews conducted in Spain, a country which has embarked on smart destinations projects and topped the World Economic Forum’s Travel and Competitiveness Index. From our analysis, we delineate and identify specific IT-enabled capabilities important for a country implementing smart tourism projects. We find that many of the IT resources available help develop key capabilities necessary for creating a design centric smart tourism ecosystem. 相似文献
