The situation analysis is often based on expert evaluations, in many cases with the participation of the market players themselves, and their synthesized group opinion is the basis of policy-making. However, the creation of opinion synthesis has not considered the market power of the players so far, and a clear research gap exists on how to properly addressing weights to the respondent experts in the group of evaluators to gain a realistic image on the present and future of the rail freight market. The objective of this paper is to identify problems, risks, and development potential in an EU national rail freight market by an expert survey based new methodology (Sectoral Group Analytic Hierarchy Process, SGAHP) that assigns different decision-maker weights in the respondent group based on the different market power of the players to gain a clear and overall image on the examined market. As a case study, a survey has been conducted in Hungary involving the significant representatives of the national rail freight. Results show that the recruitment and training of human resource is a common problem, while supporting single wagon traffic is meaningless for all players. However, big companies prioritise the reduction of locomotive maintenance time, while small ones strive to have own maintenance facilities. As an implication, the proposed model might help state decision-makers in customizing financial or other support to efficiently increase the competitiveness of the sector, as well as the rail companies to better adopt to the situation. The proposed new model has been proven successful not only from the aspect of robustness and sensitivity, but also of recommending practical modifications in rail freight to transport planners both on national and EU levels.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"33 ","pages":"Article 101579"},"PeriodicalIF":3.8,"publicationDate":"2025-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144860484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A significant challenge within these operations is managing the health, safety, and environmental (HSE) risks associated with workers’ fatigue, particularly during night shifts. Fatigue-related risks can lead to operational inefficiencies, increased accidents, and compromised safety outcomes, highlighting the need to address them within port optimization frameworks. This research presents two mathematical models to enhance container handling: the Temporary Containers Storage Model (TCSM) and the Direct Containers Loading Model (DCLM). In both models, the container yard is partitioned into blocks, with each block assigned to containers from a specific vessel. The berth is divided into positions where ships dock, and cranes are used to load containers onto the vessels. Effective resource management is essential to ensure that all containers are loaded before vessel departure. Analysis using the Lagrangian relaxation method at Shahid Rajaee Port reveals that workers experience 24 % more fatigue under the DCLM compared to the TCSM, despite the DCLM also leading to 22 % higher costs. These findings emphasize the critical importance of incorporating HSE considerations into container port operations, not only to improve safety and worker well-being but also to achieve long-term cost savings and enhanced productivity.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"33 ","pages":"Article 101577"},"PeriodicalIF":3.8,"publicationDate":"2025-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144853012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional methods for monitoring road surface conditions (RSCs) often involve time-consuming processes that require significant personnel. To address these challenges and maximize the utility of existing infrastructure, this paper presents a web-based system for real-time RSC monitoring. The system combines convolutional neural networks (CNNs) for RSC classification, a novel Nested Indicator Kriging (NIK) method for spatial interpolation, and modern web technologies to provide an intuitive interface. The system seamlessly integrates CNN models for real-time classifications using automated vehicle location (AVL) and road weather information system (RWIS) imagery. The NIK method enhances spatial coverage by classifying multiple RSC categories through two layers: the first identifies basic road conditions as bare or non-bare, while the second discriminates between more complex states, such as partially or fully snow-covered. Validated through simulations using historical data, the integrated AVL CNN model achieved a training accuracy of 99.89% and a validation accuracy of 94.62% during training, while the RWIS model reached a maximum accuracy of 98.46% and an F1 Score of 97.19%. Furthermore, the NIK method showed cross-validation accuracies averaging 73.5% for the first layer, and 86.0% for the second layer. This unified system represents an advancement in WRM decision support by automating RSC classifications and closing gaps in spatial data coverage, thus improving the efficiency and sustainability of operations and enhancing the ability of safety professionals and operators to respond to roadway hazards in real-time.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"33 ","pages":"Article 101575"},"PeriodicalIF":3.8,"publicationDate":"2025-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144853011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study contributes to understanding public transport captivity by examining perceived captivity concerning experienced and measured spatiotemporal constraints, following time-geography theory. Based on a 2022 survey in the Greater Jakarta Metropolitan Area, two-way clustering based on perceived constraints was used to capture transit user segments. Ordinal regression analysis was then performed to examine the role of constraint perception segment membership in comparison to measurable sociodemographic factors and spatial instrumental capability constraints in explaining perceived transit captivity. Results revealed that perceived capability and coupling constraints are significant factors in defining transit user segments. Three clusters were identified: flexible commuters, commuters with responsibilities, and non-driving constrained commuters. The findings show that non-driving constrained commuters and commuters with responsibilities (to a lesser extent) are more captive than flexible commuters. Segmenting users based on an individual time-geography approach helps to accurately identify captive and choice users and the in-between groups.

Furthermore, our findings indicate that the inclusion of marine equities enhances portfolio performance during the COVID-19 pandemic, although this benefit diminishes over the entire sample period, particularly during the Russia-Ukraine conflict. Our hedging analysis demonstrates that marine equities possess strong hedging capabilities. However, the bivariate portfolio analysis shows that pairing marine equities with crude oil futures, natural gas futures, or the Baltic Dry Index increases the cost of hedging against marine equity risks. Collectively, these findings support the strategic inclusion of marine equities alongside other asset classes, particularly during pandemics.

In this study, we develop new metrics to measure the impacts of sidewalk incompleteness on transit FMLM accessibility. Using data from Columbus, Ohio, USA, a typical mid-sized American city with an incomplete sidewalk network, we apply these measures and compare them to the sociodemographic characteristics of the neighborhood surrounding each stop. We find that the sidewalk network and high-quality sidewalk network have 45%-50% less spatial coverage around bus stops compared to street networks, respectively. 39% and 49% of bus stops provide access to fewer groceries and healthcare facilities, respectively, when following sidewalk networks. We observe that inner-city neighborhoods, despite being less affluent, often have better sidewalk access compared to affluent suburban areas. However, peripheral to city-center and less-affluent neighborhoods exhibit a cumulative burden with the poor sidewalk access that impacts access to essential resources such as groceries and health care.

This study aimed to compare user experiences between traditional paratransit services, as mandated by the Americans with Disabilities Act (ADA), and emerging on-demand transportation options across three U.S. transit agencies. Based on survey data from riders with disabilities who have used both services, this study offers new empirical evidence on service satisfaction and usability, a gap previously underexplored in the literature. Findings indicate overall high satisfaction levels with both paratransit and on-demand services, with on-demand options receiving favorable ratings for wait times and driver professionalism. However, Bayesian analysis showed that operational factors (i.e., wait times and drivers’ professionalism) were significant predictors of overall satisfaction, whereas service type (i.e., paratransit vs. on-demand) was not. On-demand services were often used as a complement to paratransit for time-sensitive travel, but barriers such as high costs and limited-service hours constrained broader use.
