This study examines how mobility practices have evolved in the wake of such a shock effect, focusing on the introduction of the Léman Express, a cross-border regional rail network that substantially enhanced public transport in the Greater Geneva. Drawing on two surveys conducted before (2018) and after (2022) the inauguration, we combine inductive Multiple Correspondence Analysis with Difference-in-Differences design and Propensity Score Matching to compare matched populations exposed and not exposed to the new infrastructure. We identify two latent dimensions structuring mobility practices in the region – environmental concern and valuation logic – along which the evolution of practices can be tracked while controlling for the confounding role of the COVID-19 pandemic. Our findings reveal that exposure to the Léman Express is associated with a partial attenuation of a general decline in sustainable mobility practices over the period, rather than with a positive shift. This attenuation is moreover narrow in scope – concentrated on environmental concern – and unevenly distributed across the population, remaining confined to urban, well-educated subgroups. By holding the behavioral, attitudinal, and practical aspects of mobility within a single analytical frame, this study contributes to an interdisciplinary dialogue between Transport Studies, Transit Oriented Development scholarship, and Social Practice Theories, and offers evidence on how mobility practices (do not) adapt when confronted with a major infrastructural change.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"39 ","pages":"Article 102219"},"PeriodicalIF":4.8,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148958483","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}

This structural mismatch limits the predictive utility of conventional Pavement Management Systems (PMS). To address this, a spatially validated, probabilistic hindcasting framework is proposed for characterizing pavement roughness evolution under such constraints, demonstrated on Kenya’s asphalt-surfaced national trunk road network. Using network-level surveys from 2018 and 2023, five-year International Roughness Index (IRI) class changes were modelled as an interval-based process conditioned on baseline (2018) condition, inventory, structural, and contextual attributes. Penalized logistic regression (PLR), decision tree (CART), and random forest (RF) models were trained across binary, three-class and six-class IRI formulations and evaluated under a spatially blocked nested cross-validation framework. Model performance was assessed using discrimination metrics (ROC-AUC, PR-AUC) and probability calibration diagnostics (Brier, Brier Skill, Expected Calibration Error, slope, and intercept). Post-hoc recalibration using Platt scaling and isotonic regression was applied selectively to correct miscalibration. Results show moderate-to-strong, spatially transferable discrimination (ROC-AUC = 0.66–0.87; PR-AUC consistently exceeding prevalence baselines), confirming effective ranking of deterioration risk from sparse condition archives, while CART exhibited discrimination collapse for some targets. Recalibration of PLR and RF effectively improved probability reliability. Retrospective consistency analysis incorporating attribute-change information confirmed temporal robustness of baseline models.

Existing transportation research relies heavily on surveys and self-reports that capture perceptions rather than observed behavior, while computer-vision studies achieve high detection and tracking accuracy but rarely transform trajectories into standardized indicators usable for station design, capacity assessment, or equity analysis. This study addresses this methodological gap by developing and demonstrating an interpretable behavioral measurement framework that extracts trajectory-based indicators waiting duration, interpersonal distance, trajectory entropy, walking speed, and congestion exposure from transit-station video and quantifies context-dependent differences associated with visually inferred gender presentation. A hybrid Convolutional Neural Network–Vision Transformer (CNN–ViT) architecture is employed to produce reliable, identity-preserving trajectories under the occlusion, density, and illumination conditions typical of real stations. The hybrid design combines the local feature extraction strengths of CNNs with the long-range contextual modeling of Vision Transformers, yielding higher-quality trajectories than conventional single-architecture baselines. Explainable AI techniques are used solely to enhance transparency of the computational pipeline, not to validate theoretical constructs. Behavioral differences are interpreted strictly as patterns associated with visually inferred gender under specific environmental conditions, maintaining a clear distinction from lived-experience constructs of gendered mobility. The framework bridges the disconnect between algorithmic outputs and the analytical needs of transportation planning by delivering compact, reproducible indicators that can inform passenger-flow management, station design evaluation, and operational analysis while respecting the evidential limits of observational data. The principal contribution is therefore methodological: an evidence-based measurement bridge that strengthens, rather than replaces, existing transportation knowledge.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"39 ","pages":"Article 102224"},"PeriodicalIF":4.8,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148949574","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}

The trade-off between risk and other criteria is skewed in the HAZMAT transportation context due to stringent regulatory requirements. Hence, risk is not weighted among other criteria but considered as a performance evaluator for other criteria. This reality changes the optimization goals and introduces complexities for the hazardous transportation network design problem (HNDP). It is evident that HNDPs solved in the literature often fail to penetrate actual practice. This article delivers a holistic review of the HNDP context from the literature, including risk regulatory setups and models, HNDP formulation challenges and variations, optimization approaches, and risk measures and constraints. The review reveals knowledge gaps that potentially deter the practicality of HNDP solutions. Specifically, more work is needed to develop optimization approaches that integrate non-linear cost functions and a mix of direct and indirect routing while following the user-optimal routing strategies. Data availability continues to limit such approaches. Addressing risk equity among communities and cost equity among transport carriers, requires tactical use of soft constraints and consideration of emergency response capacity. Moreover, network reliability may be critical for HAZMAT transportation and should be addressed to make HNDP solutions more practical. The review motivated the development of a novel regulator-carrier generic risk optimization framework that situates knowledge gaps within the complexities of the HNDP.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"39 ","pages":"Article 102227"},"PeriodicalIF":4.8,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148949655","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}
