In particular, we focus on the average passenger queueing delay before boarding the escalator and define it as our performance metric designated as Average Delay Before Escalator (ADBE). Two distinct arrival processes, Poisson and Single Batch, are considered to estimate lower and upper bounds for the ADBE. A probabilistic output process is used to simulate boarding decisions under varying traffic and behavior scenarios. We analyze three boarding policies: (1) all-standing, (2) walk-left-stand-right with two variants, and (3) a hybrid strategy reflecting real-world behavior. Four passenger types are defined to emulate behavioral diversity, reflecting differing urgency and space preferences. Simulation results reveal that the all-standing policy significantly reduces the ADBE and increases throughput, especially under congestion.

A key challenge in this domain is wagon failures and the resulting delays, underscoring the critical importance of timely and preventive maintenance. In this study, major stations are considered as hubs where defective wagons are consolidated and repaired. To address the multifaceted requirements of rail transport systems, a robust multi-objective mathematical model has been developed, incorporating economic and environmental objectives alongside social responsibility components, specifically, enhancing customer satisfaction (by reducing transit time) and improving employment opportunities as primary decision-making criteria. For solving the model, an enhanced epsilon-constraint method is employed for small-scale instances, while a combination of the weighted-sum approach and the Benders decomposition algorithm is applied to large-scale problems. Subsequently, a sensitivity analysis is conducted to evaluate the stability of solutions against variations in key parameters. Sensitivity analysis shows that wagon capacity is the most influential parameter, as increasing it significantly reduces infrastructure, transportation, inspection, and reward costs. Demand is another highly sensitive factor, directly affecting the number of hubs, locomotives, and the overall network size. Within the tested ranges, the model remained stable and no infeasibility was observed. Numerical results demonstrate that the proposed model not only exhibits high efficacy in managing rail transport networks but also simultaneously fulfills sustainability, economic, and social objectives.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"38 ","pages":"Article 102112"},"PeriodicalIF":4.8,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148476599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the Czech Republic, shared-use paths are increasingly used by e-bikes and scooters. Higher speeds and traffic volumes on shared-use paths have increased the number and severity of injuries. This research was set out to investigate the impact of measurable parameters on conflict prediction. Locations on 10 different shared-use paths were chosen, and 40 h of bird’s-eye video footage were recorded, analysed using the YOLO algorithm for detection of shared-use path users, and tracking their routes using the BoT-SORT algorithm. For all trajectories, lengths, average speeds, direction of motion, and time were calculated, along with mutual interactions. For every location, path width was measured, and conflicts and potential conflicts were evaluated. Volumes were processed into 15-minute intervals, and baseline characteristics were calculated. Machine Learning methods were used to analyse the dataset and visualise the results to better understand the conflict prediction model. The results confirm that higher traffic volumes increase the proportion of conflicts, while greater path width helps mitigate these risks. Conflicts are more likely with a higher proportion of cyclists and at lower speeds and higher volumes, suggesting congestion is a contributing factor. These findings underscore the importance of well-designed infrastructure, particularly wider paths, in enhancing safety and fostering harmonious coexistence among diverse user groups on shared-use facilities.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"38 ","pages":"Article 102116"},"PeriodicalIF":4.8,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148476689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among these factors, density shows the strongest association with perceived PV, while accessibility and proximity to transit demonstrate comparatively stronger links with perceived EO and BG. Overall, the findings suggest that TOD characteristics are consistently associated with favorable economic perceptions among local business actors.

These operations face tight schedules, resource constraints, and disturbances that can cause delays. Multi-skilled resources enhance flexibility by enabling multiple operations, reducing idle time and improving resilience to disturbances. Tactical optimisation of ground handling operations is investigated, focusing on allocating and scheduling multi-skilled resources. A new optimisation model is proposed to tackle the problem of allocating multi-skilled resources to interdependent ground handling operations under temporal, spatial, and disturbance-related constraints. To address the computational challenges of solving real-world problem instances, a heuristic-based approach is developed, as these instances prove too complex for traditional linear optimisation methods. The proposed approach is tested using a case study based on a full day of operations at Düsseldorf Airport, applied to a simplified layout representation, showing its ability to minimise delays and improve workforce efficiency. The results show significant advantages of incorporating multi-skilled resources, including increased flexibility and reduced delays. For example, with 600 resources and 60% disturbed operations, the higher-skilled resource set reduced total delay by 26% compared with the lower-skilled set. The heuristic solved all tested instances in less than one second, whereas exact optimisation required up to 24,097 s and became intractable for larger instances. These findings demonstrate that tactical scheduling with multi-skilled resources can improve both operational resilience and computational tractability. The results further show that the proposed approach extends existing ground handling planning methods by enabling proactive tactical scheduling under realistic operational constraints.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"38 ","pages":"Article 102127"},"PeriodicalIF":4.8,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148476685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
