      <title>Maintenance management in shipping: the intricate interplay between organizations, technology, and humans</title>
      <link>https://trid.trb.org/View/2706091</link>
      <description><![CDATA[The maritime industry is undergoing a transformative shift with the integration of digital technologies altering maintenance management practices. This qualitative study explores the following question: What opportunities and risks do shipping companies associate with maintenance management when adopting digital technology? The empirical data material stems from a workshop involving stakeholders from 14 Norwegian shipping companies. The findings highlight significant opportunities for more effective maintenance strategies, enhanced data integration, and improved real-time collaboration between ship and shore. The transition poses several challenges related to system interoperability, data ownership, competence development, and informal social structures. The increasing reliance on digital tools raise concerns about power structures, cultural resistance, insufficient digital competencies, and the erosion of crew autonomy and expertise. These findings emphasize the need for a systemic approach that integrates technical, organizational, and social dimensions. To mitigate future risks, strategic planning, robust change management, and fostering a culture of adaptability and trust are essential. This study underscores the importance of aligning technological innovations with organizational goals to ensure sustainable and effective maintenance management in the future.]]></description>

      <title>Mobilities, social ties, and quality of life in the digital society: A configurational approach</title>
      <link>https://trid.trb.org/View/2720684</link>
      <description><![CDATA[Communications and transport are increasingly integrated through the widespread application of information and communication technologies (ICTs). Digital platforms serve both as support for transport practices and as partial substitutes for them, transforming the ways in which social ties are organized and reshaping individuals’ pathways towards good quality of life (QoL).Using a configurational approach to compare the roles of digital and transport networks, this paper presents an analytical framework for revealing the complexity of individual-level configurational relationships between mobilities, social ties, and wellbeing outcomes. The authors use socio-technical regime evolution theory to construct a deployable framework for a series of fuzzy-set qualitative comparative analyses (fsQCA) (N = 729). The framework enables us to explore the interactive relationships between individuals’ perceptions of mobility, perceived norms of mobility use, and the social ties that support mobility access. Social-tie–mobility set-theoretic causal pathways that are sufficient for membership in the good health-related QoL outcome set, measured using EQ-5D-5L, are identified and discussed for younger, middle-aged, and senior populations. The analysis provides a better understanding of how physical and digital mobilities, social ties, and mobility norms are configured in relation to quality of life in digital societies.]]></description>

      <title>Observation-driven segmentation of photogrammetric point clouds via line-of-sight concentration</title>
      <link>https://trid.trb.org/View/2743329</link>
      <description><![CDATA[Photogrammetric reconstruction based on Structure-from-Motion (SfM) enables efficient acquisition of 3D point clouds, yet automatic foreground segmentation of target structures remains challenging in complex scenes. This paper proposed an observation-driven method for point cloud foreground segmentation, introducing a Line-of-Sight Concentration (LoSC) descriptor to quantify multi-view observation consistency. An observation-guided two-stage region-growing framework is developed to extract main structures without semantic labels or training data. The method is validated on a laboratory masonry arch bridge, two historical masonry arch bridges and further extended to a laboratory timber corridor bridge to verify its generalization. With Particle Swarm Optimization (PSO) for parameter tuning, the approach achieves stable performance, yielding voxel-IoU of around 0.8 and F1-scores above 0.88 for masonry arch bridges. Comparative experiments demonstrate clear advantages over K-Means and conventional region-growing methods. The results confirm that LoSC effectively highlights structural surfaces, enabling robust and automated foreground extraction for Scan-to-BIM and infrastructure digitalization workflows.]]></description>

      <title>Artificial intelligence in ports: a bibliometric and evolutionary perspective</title>
      <link>https://trid.trb.org/View/2698267</link>
      <description><![CDATA[Container terminal operations are rapidly adopting artificial intelligence (AI) technologies to improve efficiency, sustainability, and automation amid ongoing digital transformation. This study conducts a comprehensive bibliometric analysis of 391 publications (1992-2024) from the Web of Science Core Collection using Biblioshiny 4.0. The findings reveal a paradigm shift toward AI-driven optimisation across key areas, including berth allocation, crane scheduling, truck fleet management, and intelligent port automation. Despite this progress, a critical gap remains: the lack of empirical validation using real operational data. This gap highlights the urgent need for cross-industry collaboration to bridge theory and practice. The study urges policymakers and port authorities to implement standardised AI frameworks, invest in workforce upskilling, and enhance digital infrastructure. Future research should focus on scalable, data-validated AI applications and on promoting longitudinal case studies and industry partnerships to ensure the effective, sustainable integration of AI technologies into port logistics.]]></description>

      <title>Impact of digital economy on sustainable development in Chinese port cities</title>
      <link>https://trid.trb.org/View/2698264</link>
      <description><![CDATA[This article combines panel data of 18 major Chinese port cities from 2011 to 2021. Partial least squares and coupled coordination degree models are used to explore the mechanism and relationship of digital economy on sustainable port development. Results show: 1) In terms of spatial-temporal evolution, the digital economy generally shown a stable growth trend, with significant differences between cities. In terms of dimensional evolution, developmental stages are digital infrastructure, industrial digitisation, and synergistic development of industrial digitisation and digital industrialisation; 2) the sustainable development of ports shows a fluctuating trend, with differences in levels and a 'Matthew effect'. Sustainable development levels are concentrated in the low, medium-low, and medium levels; 3) the impact of urban digital economy on port sustainable development involves three stages: port-driven, city-driven, and dual-driven, with high coupling between the two but relatively low coupling coordination degree.]]></description>

      <title>Development and Application of a Digitalized Document Management System to Update Highway Operation and Management Systems Using Building Information Modeling</title>
      <link>https://trid.trb.org/View/2697825</link>
      <description><![CDATA[Highway operations and maintenance (O&M) systems are essential for ensuring safe and uninterrupted mobility. However, traditional highway operation, maintenance, and accident documentation systems (HOMADMS) still depend heavily on manual processes such as police reports and on-site inspections. These practices often result in inefficiencies, delays, inconsistent records, poor communication, and fragmented data handling, all of which hinder timely decision-making, increase operational costs, and compromise safety. This study introduces a digitalized HOMADMS, named RADM-BIM, developed using building information modeling (BIM). The system addresses long-standing documentation challenges by providing a structured, real-time, and integrated platform for managing accident events, inspections, and O&M activities. The research followed a three-phase methodology: identifying systemic HOMADMS issues through a literature review and expert interviews; developing a BIM-integrated solution using a customized plugin and application programming interface (API) in Autodesk Revit; and validating the system through a case study on an Indian National Highway project. Results from the case study demonstrate that RADM-BIM streamlines accident documentation, supports predictive maintenance planning, and generates reliable, auditable digital records that overcome the inefficiencies inherent in conventional systems. The system enhances data accessibility, reduces retrieval time, and improves decision-making through standardized and real-time reporting. By extending BIM beyond design and construction into the postconstruction O&M phase, the study embeds accident and inspection workflows within a unified digital model and demonstrates its effectiveness through industry-based testing. This study contributes to the body of knowledge in construction engineering and management by introducing the first BIM-integrated framework specifically designed for the postconstruction highway O&M phase. It establishes a structured, real-time digital documentation process that enhances traceability, improves operational decision-making, and provides a scalable and replicable model for proactive, integrated, and data-driven highway asset management, offering measurable benefits for engineers, managers, and policymakers.]]></description>

      <title>The Infrastructure of Seaports—The Guarantor of State Security</title>
      <link>https://trid.trb.org/View/2579449</link>
      <description><![CDATA[Since 2004 March 10, after Lithuania became a member of the North Atlantic Treaty Organization (NATO), it has been committed to improving national security and close cooperation with NATO countries. Therefore, military mobility is one of the priority areas of the state. However, it is impossible to fulfil this obligation without inadequate infrastructure. Digitization of seaports is one of the most important processes to increase operational efficiency, competitiveness, and adaptability to changing circumstances. Digitization allows you to optimize seaport operations, monitor real-time changes, and integrate your transport with other parts of the transport chain. It also ensures the safety of cargo and ship movement. The cargo and goods information system (KIPIS) operates in Lithuania’s maritime sector. There are constant investments in the infrastructure of the Klaipeda State Port, i.e. 98 million in 2023 EUR in 2024–2027, and as much as 234 million is foreseen. Eur. However, military cargo transportation faces various challenges, such as the constant information change and the lack of storage space for military equipment. The article aims to assess the infrastructure of the Klaipeda State Port for the host country’s support and to make suggestions for future development. To achieve the goal, an analysis of the scientific literature on seaport activity and infrastructure was carried out based on secondary data, the existing infrastructure of Klaipeda State Ports was reviewed, and based on primary data, proposals for improving the infrastructure of Klaipeda State Port will be formulated, assessing the scale of the host country. A systematic and comparative analysis of the concepts published in the scientific literature, statistical processing, in-interview, and Kendall’s methods of expert compatibility were used to achieve the purpose and tasks of the article.]]></description>

      <title>Digitalization of Mechanical Labs for Enhanced Traceability and Virtual Verification</title>
      <link>https://trid.trb.org/View/2712100</link>
      <description><![CDATA[Digitalization is the process of leveraging digital technologies to transform business operations, processes, and models, enabling organizations to improve efficiency, create new value, and enhance customer experiences. It is essential as it enables data-driven decisions and reduces product development time. It’s easier to Digitalize new products however, transforming existing products and processes is a challenging task, as constituents are in various phases of lifecycle. Also, the existing/ legacy data acts as a starting point for future programs. Currently, teams are spending hours to weeks finding the right processes and data, costing ~$14,000 per test based on labor hours. To tackle this challenge, Mechanical labs are digitalizing their data and processes alongside physical tests via 3DEXPERIENCE application to capture data in digital models and ensure traceability for which Requirement Functional Logical Physical (RFLP) framework is leveraged. This traces Requirements to its functional elements that are allocated to the logical elements forming a basis for behavior analysis. Further integrating the physical entities (Virtual product/s) to RFL enables realistic simulation capability. This framework has been implemented on some structural tests involved in the development of composite material for future. Results show a clear traceability between requirements and their chain of elements, estimated to reduced 2 hours of search efforts into 15 minutes. Now teams spend more time on analysis of required systems. The realistic simulation capability was used to verify a step in the test machine configuration, thereby saving time to verify during test execution and paving way for virtual verification of requirements.]]></description>

      <title>Automating Compliance Workflows in Aerospace Systems: A Scalable Framework for Specification Review and Requirement Mapping</title>
      <link>https://trid.trb.org/View/2712099</link>
      <description><![CDATA[Compliance verification in aerospace systems often relies on labor-intensive workflows that demand extensive manual effort to produce structured review documentation and requirement matrices. These processes can span dozens of hours per review, are vulnerable to inconsistencies due to non-standardized annotations, and depend heavily on individual interpretation of fragmented technical sources. With a growing backlog of review tasks and a steady influx of new requests, the need for scalable automation has become increasingly important. This study presents a modular automation framework designed to streamline compliance assessments through intelligent document parsing, requirement extraction, and matrix generation. The system integrates optical character recognition, computer vision, and natural language processing techniques to process both scanned and digital documents. By digitizing data across multiple hardware configurations and automating extraction from diverse technical records, the framework enables consistent evaluation across a broad spectrum of requirement categories. Automation scripts and standardized templates facilitate rapid population of compliance matrices, reducing manual hand-offs and minimizing reliance on specialized expertise. Implementation led to a 39% reduction in turnaround time and a 62% increase in monthly throughput, demonstrating measurable efficiency gains in the compliance review process. This framework exemplifies how intelligent automation can drive operational efficiency, deliver measurable cost savings, and pioneer data-driven and scalable innovation in aerospace compliance engineering.]]></description>

      <title>Integrating Formal Methods into Model Based Systems Engineering to Mitigate Requirement Escapes</title>
      <link>https://trid.trb.org/View/2712096</link>
      <description><![CDATA[The aerospace industry is undergoing a significant digital transformation in the way system requirements are defined, communicated, and managed. Major OEMs are moving towards fully model-based development processes, with plans to deliver requirements exclusively in the form of models. It is no longer sufficient to manage requirements using traditional document-based approaches; instead, organizations must adopt tools and processes that enable the consumption, interpretation, and implementation of model-based requirements. However, MBSE itself does not ensure that the requirements defined within the model are complete or consistent. Without rigorous validation techniques, even well-structured models can carry forward poorly defined or conflicting requirements — leading to errors that propagate throughout the development lifecycle. This work proposes an approach that integrates formal methods into MBSE workflows by enabling completeness and consistency checks of SysML-based requirements within Cameo Systems Modeler. The method bridges Cameo Systems Modeler with formal analysis tool by transforming modeled requirements in Cameo into analyzable formal specification. The transformed formal requirements allow engineers to identify missing, conflicting, or unreachable requirements early in the development lifecycle, while also aiding automated test generation.]]></description>

      <title>How does digital transformation affect ports’ green transition? Empirical evidence from China</title>
      <link>https://trid.trb.org/View/2692379</link>
      <description><![CDATA[Enterprise digital transformation is an important component and microcosmic manifestation of the digital economics, and it plays a significant role in advancing enterprises' green transformation. Using the panel data of China's A-share listed port companies from 2010 to 2024, this paper constructs digitalization and green transformation indicators at the port enterprise level to explore the impact of digital transformation on the green transformation within port enterprises. The empirical results reveal a statistically significant positive relationship between digital transformation and green transformation in port enterprises. Mediating mechanism analysis further shows that digital transformation reduces supply chain concentration, while higher supply chain concentration impedes the green transition of port enterprises. Therefore, digital transformation positively affects green transformation through the mediating effect of supply chain concentration. Furthermore, digital transformation effectively enhances information transparency, which in turn facilitates green transformation. Information transparency plays a significant mediating role between digital transformation and supply chain concentration. Heterogeneity results show that the impact of digital transformation on green transition varies across ports in different regions. The effect is most pronounced in the central coastal ports, followed by the southern coastal ports. However, in the northern coastal ports and Yangtze River inland ports, the role of digital transformation in advancing green transition is not significant. Furthermore, the impact of digital transformation on green transition also differs by port size. The larger ports exhibit a more pronounced positive effect of digital transformation on green transition compared to smaller ones. The conclusions provide important policy implications for promoting the coordinated transformation of digitalization and green development in the port operations.]]></description>

      <title>Logistics in Latin America and the Caribbean: Opportunities, Challenges and Courses of Action</title>
      <link>https://trid.trb.org/View/2685470</link>
      <description><![CDATA[Logistics, understood as the set of planning, implementation and control processes that ensure an efficient flow of goods, services and information throughout the supply chain, plays a key role in the economy. Given that inputs, production nodes and consumer markets are distributed in space, logistics allows overcoming the friction of distance and creating spatial convergence between supply and demand (Barbero, 2010). Thus, logistics influences the level of competitiveness and productivity of a country, while providing employment opportunities and access to goods and services for its inhabitants. In aggregate terms, the logistics performance of Latin America and the Caribbean (LAC) presents a significant lag compared to other regions. International indicators show that LAC systematically rates below the levels of advanced economies, while its own rating has fallen in recent decades. What are the reasons for this setback? What impact does it have on the development goals of the region? How to reverse this trend? These will be the main questions we will address in this post. To this end, in the first chapter we will explore the relationship between logistics and development goals, and we will quantify the benefits of progress in logistics for LAC countries. Chapters 2 to 5 will analyze the situation of road, rail, sea and air modes in the region. In Chapter 6, we will review the state of trade facilitation, an important complement to international logistics operations. Chapters 7-9 will explore three new challenges in the sector: urban logistics, digital transformation, and decarbonization. In Chapter 10, we will address the geographic dimension of logistics and the importance of multimodality. Finally, in Chapter 11 we will present a roadmap with improvement actions in the short, medium and long term, and in accordance with the state of progress of the sector in the different countries of the region.]]></description>

      <title>Practices for Transitioning to Digital Delivery Systems and Workflows</title>
      <link>https://trid.trb.org/View/2724648</link>
      <description><![CDATA[The transportation sector is undergoing a rapid transformation driven by digital technologies that are influencing how infrastructure is planned, designed, delivered, and managed. Across the United States, state departments of transportation (DOTs) have reported increasing interest in the potential of digital delivery, which is the exchange and use of digital information in standardized, accessible formats, to improve efficiency, reduce costs, and enhance lifecycle asset management. This shift is motivated by the need to overcome longstanding challenges associated with fragmented workflows, costly change orders, and inefficiencies tied to traditional processes and practices. This report, NCHRP Synthesis 664, documents state DOT practices for adopting and implementing digital delivery. Practices identified by the synthesis cover issues such as the status and maturity of digital delivery transitions, policy changes supporting implementation, documentation practices, organizational structures and champions, IT infrastructure, training, transition communications, data governance, and assessment. The report is organized as follows: chapter 2 is a review of existing literature on transitioning to digital delivery; chapter 3 summarizes survey results; chapter 4 provides five case examples of digital delivery transitions; chapter 5 summarizes findings from previous chapters and identifies the gaps in knowledge that could be addressed through future research.]]></description>
