Item Restricted Addressing risk, challenges, and solutions in Megaprojects: A case study of Neom Smart City in Saudi Arabia(leeds beckett university, 2024) Alluqmani, Waleed Salem; Omotayo, TemitopeNeom Smart City is designed as a high-tech city with sustainable living and renewable energy sources such as solar power and autonomous transportation systems. The City aims to become an attractive destination for talents and investment Mega Projects are more common in the 21st century due to global population growth, urbanisation, and technological innovation that requires the establishment of big projects. The aim of this research is to focus on risks, challenges, and solutions that may occur at the Neom Smart City project in KSA, and provide insights for the effective management of megaprojects. A positivist philosophy and a deductive research approach was used in this research. The overarching methodology was quantitative. The data-gathering procedure involved questionnaire instruments. The sample involved twenty participants including project managers, while the data analysis technique used was descriptive and inferential statistics using SPSS and crucial ethical considerations were confidentiality and informed consent. Descriptive analysis of the findings have revealed that the participants perceived financial risks to be the most important concerns, followed by legal and construction risks. The result from the study also shows poor planning, political failures, and the lack of high-performing teams were the most significant contributor to the failure of megaprojects. The inferential statistics have revealed that there is a significant positive correlation between design risks and legal risks, contractual risks, construction risks and operational management risks. Financial risks are linked to construction risks, political risks, and leadership risks. Empirically, financial risks are influenced by contractual risks, poor leadership, and poor planning. The outcomes also suggest that stakeholder collaboration has a statistically significant impact on construction risks.7 0Item Restricted SMART INFRASTRUCTURE AND PARKING CITATION REVENUE IN THE PUBLIC SECTOR: THE ROLE OF SOCIOECONOMIC AND URBAN ENVIRONMENT FACTORS(University of Colorado Denver, 2024) Alharbi, Ahmad; Gregg, Dawn; Dincelli, ErsinThis dissertation investigates the impact of IoT projects on parking citation revenue (PCR) generation in the public sector, focusing specifically on smart parking systems (SPS). The research uses two empirical case studies to understand how SPS affects PCR and how various moderators, how socioeconomic status (SES) and urban environment factors, such as business vitality (BV), population density (PD), and amenity per capita (APC), influence this relationship. Study 1 examines the moderating effect of SES on the relationship between SPS and PCR. Grounded in the Transaction Cost Economics (TCE) framework and digital divide literature, it hypothesizes that higher SES areas, characterized by better access to technology and higher digital literacy, would experience a weakened positive relationship between SPS and PCR due to improved compliance and fewer violations. Utilizing a longitudinal dataset of 263,578 parking citations from Los Angeles (2015–2023) and employing a random-effects (RE) model, the findings confirm that in higher SES districts, the positive impact of SPS on PCR is diminished. Conversely, SPS leads to increased PCR in lower SES areas, highlighting the importance of addressing the digital divide to ensure equitable benefits from smart city initiatives. Furthermore, applying time limit (TL) policies within the SPS yields differential outcomes depending on the durations established. Specifically, shorter time limits are associated with increased PCR, while longer time limits correspond to decreased PCR. This underscores the influence of TL policies on parking behavior and compliance rates. Study 2 uses the Technology-Organization-Environment (TOE) framework to investigate how urban environment factors, BV, PD, and APC, moderate the SPS-PCR relationship. The hypotheses suggest that BV, PD, and APC would strengthen the positive impact of SPS on PCR due to higher parking demand. The results reveal that PD positively moderates the SPS-PCR relationship, supporting the hypothesis. However, contrary to expectations, higher BV and APC weaken the positive impact of SPS on PCR, possibly due to the availability of private parking options and policies prioritizing accessibility over strict enforcement in amenity-rich areas. The dissertation highlights the influence of socioeconomic and urban environmental contexts on technology effectiveness, using TCE and TOE frameworks. Practically, it provides insights for policymakers and urban planners, emphasizing the need for context-sensitive strategies in implementing IoT technologies to optimize benefits, address the digital divide, and achieve equitable, efficient, and sustainable urban development.27 0Item Restricted Mechanical Energy Harvesting from Random Pedestrian Movement(Cranfield University, 2024-06-26) Alnuman, Abdulaziz; Khan, Muhammad; Starr, AndrewThis thesis presents a groundbreaking exploration into piezoelectric energy harvesting, culminating in the development of the "Alnuman & Khan Mat" (AKM), a novel energy-harvesting solution designed for high-footfall environments. Central to this research is the introduction of a predictive polynomial equation (the Alnuman equation), a significant contribution by the author, which serves as a cornerstone for future design and optimisation in the field. Commencing with an extensive review of current literature, the research identifies gaps in existing methodologies, setting the stage for innovative advancements. A key focus is the empirical investigation into the intrinsic and extrinsic properties of PZT-based structures, leading to a deeper understanding of their modal responses to random excitations. This exploration results in the AKM, an energy-harvesting mat optimised through iterative design processes, capable of efficiently converting kinetic energy from pedestrian movements into electrical energy. Experimental validation of the AKM demonstrates its efficacy, with the mat achieving a peak voltage output of approximately 25.72864 volts and a root mean square (RMS) voltage, at its highest in the series of experiments, of 3.0261 volts, . The Alnuman equation introduced by the author plays a pivotal role in accurately predicting the electrical output of energy-harvesting mats based on specific parameters. This equation, validated against experimental data, marks a significant theoretical advance, bridging the gap between theoretical understanding and practical application. The thesis contributes substantially to the field of sustainable energy, offering insights into material optimisation, empirical methodologies for modal responses, and the integration of theoretical and practical knowledge. Future work proposed includes exploring alternative piezoelectric materials, optimising mat design, implementing the AKM in urban spaces, and enhancing energy storage and management systems. Finally, this research not only enhances the current understanding of piezoelectric energy harvesting but also paves the way for future innovations in sustainable energy solutions, particularly in urban and high-footstep environments.18 0Item Restricted Smart Cities as Alternative Digital Solutions for a More Sustainable Liveable Future at the Urban Level in the UK and Europe(Saudi Digital Library, 2023-12-06) Alkahtany, Faisal; Kao, Ping-JenThe current study specifically focuses on exploring the potential of sensors used in smart cities, which is an alternative digital solution, and how using sensors in smart cities can ensure a sustainable, liveable future at the urban level of the UK and Europe and the fundamental difference between Smart cities and typical cities.18 0Item Restricted Understanding how open government data (OGD) governance strategies are influenced by the institutional context of local government in smart cities worldwide(Saudi Digital Library, 2023-11-07) Alrawi, Mehad; Lamb, John; Bayat, AliSmart cities use ICTs not only to develop their infrastructure but also to involve citizens in their internal policies and create innovative solutions to urban problems. Accordingly, interest has increased in sharing data with the public to empower them and encourage public innovation through the exploitation of the expansion of ICT. This can facilitate direct communication between power holders and citizens to achieve the greatest interaction among all stakeholders. However, cities may not adopt the same strategy for sharing their data, as the type, amount, and transparency of disclosed data may differ based on their context. Nonetheless, there is a lack of research concerning how various contexts influence variation in sharing public data initiatives. This study aims to explore the contextual determinants of data governance in smart cities globally, integrating an extended version of institutional theory and the Technology-Organization-Environment (TOE) framework to create its theoretical framework and examine how the institutional context of local governments affects their choice of four strategies for sharing public data: provider, platform, enabler, and automated system. Data from 100 smart cities is collected by combining secondary and primary data. Study findings reveal that open data strategies and the maturity levels of their technologies vary among smart cities in the world’s six regions, and the impact of institutional context is undeniable while planning open data initiatives. Institutional context factors such as vision and orientation to investing in ICTs, decision-making centralisation, democracy level, level of authority or autonomy, and governance challenges are key determinants of the local government’s approaches to sharing public data, which in turn help develop smart city initiatives. Therefore, this study illustrates that various dimensions of context can affect the success of smart city governance, and it is essential to consider the institutional context and the unique characteristics of each city while developing smart initiatives.21 0
