Exploring barriers and enablers to active travel through the lens of the practitioners planning for and promoting its uptake can uncover underlying mechanisms that shape travel choices and encourage more effective interventions. This study uses online survey data from practitioners working in the planning and provision of active travel related initiatives (N = 40), to understand international experiences, as influenced by the surge of interest in active travel during the pandemic. We base our investigations and analysis on two policy process theories – the Multiple Streams Framework and Punctuated Equilibrium Theory. Drawing tools and concepts from both, we provide a synthesis of international experiences with planning for active travel, and analyse how professionals perceive existing obstacles and opportunities for active travel provision once the immediate impacts of the pandemic have waned. Our findings reveal a pervasive adherence to the status quo – while certain policies temporarily adapted to accommodate the pandemic’s disruptions, the pandemic failed to trigger substantial actions for our sample. The primary challenge lies in the enduring dominance of car-centric cultures and urban form, suggesting both a lack of community understanding about the issues associated with car usage, and ongoing structural barriers of cities planned around cars. Notwithstanding, the emergence of active travel projects and strategies since the onset of the pandemic, coupled with increasing public awareness of active travel, could be valuable in laying the groundwork for future long-term changes, even if their immediate impact is not yet evident.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"28 ","pages":"Article 101259"},"PeriodicalIF":3.9,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142532415","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}

To address this problem, a novel decision-making approach is proposed, integrating the best-worst method (BWM), fuzzy hierarchy risk assessment (FHRA), and additive ratio assessment (ARAS). This approach decomposes the route decision-making problem into a hierarchy structure and determines the optimal solution through three distinct phases. In the first phase, BWM assigns relative weights to various criteria within the hierarchical structure, ensuring that the decision-makers’ preferences are accurately reflected. In the second phase, FHRA evaluates qualitative risks from the lowest to the highest hierarchy levels. This process involves calculating risk magnitudes at the lowest hierarchy level and progressively recalculating them as they ascend to the highest level of the hierarchy. The multimodal transport cost-model provides transportation cost and time. In the final phase, ARAS synthesizes all the decision-making data to rank all possible multimodal alternative routes based on utility scores. The realistic case study validates the practical applicability and effectiveness of the proposed approach. The findings indicated that the proposed methodology effectively identify the most appropriate multimodal transport route as the best compromise choice. This study contributes new knowledge regarding a new hybrid decision-making framework that combines multiple criteria decision-making methods with fuzzy hierarchy risk analysis, thereby enhancing the design of transportation plans to align with organizational goals and customer requirements.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"28 ","pages":"Article 101252"},"PeriodicalIF":3.9,"publicationDate":"2024-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142533226","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 study specifically explores the role of dynamic route choice behavior within micro-simulation frameworks, emphasizing its application in the context of motorcycle-dominated traffic in Ninh Kiều District, Cần Thơ, Vietnam. By integrating discrete choice models for route selection with rigorous calibration and validation in AIMSUN, the study developed a comprehensive traffic simulation model for large-scale networks. Findings reveal that motorcycles dynamically adjust routes based on current traffic conditions rather than adhering strictly to shortest path strategies. However, the availability of roadside traffic information systems accessible to motorcycles in developing countries is limited, hindering optimal route choices. To address this gap and encourage the enhancement of route choice behavior, the study evaluates the impact of real-time traffic information provision using Macroscopic Fundamental Diagrams within the micro-simulation model. The results demonstrate significant improvements in network efficiency when informed route selection behaviors are facilitated, particularly with comprehensive coverage across all road types. Higher compliance rates notably improved network capacity by up to 84%. Overall, this study contributes methodologically by increasing model precision and practical insights into managing heterogeneous traffic environments, highlighting the transformative potential of traffic information systems and advocating for broader implementation in similar motorcycle-centric regions, which currently still rarely extend beyond toll roads. Future research should extend these methodologies to diverse urban contexts for broader validation and application.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"28 ","pages":"Article 101247"},"PeriodicalIF":3.9,"publicationDate":"2024-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142533267","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 study uses an explainable artificial intelligence approach to investigate the changes in those telecommuting across three periods: i) pre-pandemic, ii) pandemic, and iii) post-pandemic periods. Machine learning methods, including decision trees, random forest, extreme gradient boost, naïve Bayes, and artificial neural networks, were developed across the study periods. Shapely Additive Explanations, a model-agnostic approach, explains the best-performing model for each period. Results show that before the pandemic, gender and occupation were major determining factors of telecommuting adoption. However, the pandemic reduced the impact of these factors, making income and education levels a more significant factor for identifying telecommuters. Additionally, the study examines interaction effects between these features, allowing for a deeper investigation of specific aspects of interest.

Adequate operational quality requires a certain level of robustness to delays and disruptions, but on segments with confined capacity, robustness becomes more fragile with increased traffic demand and speed heterogeneity. This trade-off between capacity utilization and service robustness predominantly manifests itself by compromising the reliability of rail freight services for two main reasons. Firstly, passenger trains are often prioritized in dispatching over freight trains. Secondly, many freight trains operate over longer distances and they accumulate more delays. Decreasing speed heterogeneity in mixed traffic may become pivotal in the interplay between robustness and capacity utilization. In this paper, we investigate possible improvements in capacity utilization and in railway service quality when introducing faster freight trains in mixed-traffic operations. The analysis is carried out on the Swedish Southern Main Line, which forms part of the Scandinavian–Mediterranean freight corridor. Microscopic simulation is used to explore performance indicators, such as simulated running times with respect to scheduled running times, capacity utilization, and punctuality, by implementing and comparing scenarios with different maximum speeds for freight trains. The results suggest that increasing the top speed of freight trains might seem as a promising approach for reduced utilization of capacity in the planning stage, but the stochasticity of operations in mixed traffic may become more challenging for delay recovery.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"28 ","pages":"Article 101242"},"PeriodicalIF":3.9,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142434049","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 findings indicate that in the absence of quantum entanglement, achieving a Pareto optimal strategy in which both parties share private parking is challenging.
