This study examines potential ship bypass phenomena under unilateral carbon policies by establishing a stochastic evolutionary game model involving a cross-border maritime enterprise, a carbon policy country, and a bypassing country. We then perform a parameter sensitivity analysis based on the game’s stability conditions. Key findings are outlined below: (1) In the current situation, the unilateral carbon policy will inevitably result in the phenomenon of bypassing of ships. (2) The implementation of synergistic strategies by bypassing countries elevates the variability in cross-border maritime enterprises’ strategic decisions. Specifically, these strategies mitigate the occurrence of bypassing to a certain degree, indicating a potential reduction in its frequency. (3) Bypass countries exhibit a heightened sensitivity toward the degree of synergy in carbon policies and the potential collaborative gains resulting from the improved international standing arising from such synergy. This suggests a greater interest in the long-term advantages conferred by harmonized carbon policies. (4) As stochastic perturbations intensify, bypassing countries exhibit the highest level of volatility, potentially deviating from their original synergistic strategy and adopting a non-synergistic carbon policy. This suggests that their strategic decisions are particularly unstable in response to external disturbances. (5) With an increase in random perturbation intensity, compared with the carbon tax policy, the carbon trading policy exhibits stronger stability, indicating that the implementation of the latter policy is more conducive to cross-regional carbon policy synergy.</div></div>","PeriodicalId":47824,"journal":{"name":"International Journal of Sustainable Transportation","volume":"19 9","pages":"Pages 837-853"},"PeriodicalIF":3.9,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144907757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a lack of data has led to a dearth of data-driven research on personally owned e-bike usage. We present longitudinal findings from the CanBikeCO program, focused on e-bike adoption and use across demographics, trip characteristics, and geographies in the state of Colorado. CanBikeCO recorded travel survey data from low-income individuals provided with personal e-bikes by the Colorado Energy Office in six communities across Colorado from July 2021 to December 2022. The data were collected using a custom instance of the National Renewable Energy Laboratory OpenPATH platform, which combines passive data collection with semantic information such as trip mode and purpose labels. To our knowledge, there are no prior travel survey data on personally owned e-bikes with this range and scope. Insights from this unique dataset include: (i) work trips were 17% more likely than average trips to be taken on an e-bike, (ii) e-bikes were most often reported to replace cars (34% of e-bike trips) and other personal micromobility devices (22%), and (iii) participants favored walking for trips less than 1 mile, e-bikes for trips of 1–3 miles, and e-bikes, cars, or shared rides for trips of 3–20 miles. The data used to generate these results have been made available in the Transportation Secure Data Center. We find e-bike use is appealing across age groups and may be related to characteristics of land use, urban form, occupation, income, and car ownership. We conclude for this population that the energy demand added by e-bike use (induced demand and replacing non-motorized modes) is outweighed by the reduction in energy demand from replacement of single-occupancy vehicle trips with e-bike trips. Our findings suggest considerable potential for energy savings from personal e-bike ownership.</div></div>","PeriodicalId":47824,"journal":{"name":"International Journal of Sustainable Transportation","volume":"19 9","pages":"Pages 815-836"},"PeriodicalIF":3.9,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144907832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the inherent complexity of hydrogen supply chain (HSC) presents hurdles in production, transport, and utilization, leading to low utilization and increased costs. Hydrogen supply chain network design (HSCND) and hydrogen fueling station planning (HFSP) both aim to optimize HSC from different angles, but integrating these two into a single framework poses challenges. Furthermore, HSC design directly influences hydrogen fuel cell vehicle (HFCV) adoption, influenced by factors like vehicle registration, driving tolerance range, traveling range, and more. The aim of this study is to develop an end-to-end supply chain framework that simultaneously considers HSCND and HFSP, encompassing all segments of the HSC. We design a two-stage model that aligns with each stage of HSC. From the end-user’s (station) perspective, we find optimal locations of Hydrogen Refueling Stations (HRSs) on expressways by means of a capacitated flow-refueling location model (CFRLM) combined with a hydrogen vehicle refueling station logic. This model considers government policy and consumer adoption factors with the goal of striking a balance between consumer interests and HRS decision-makers. For transporting byproduct production, we use a Voronoi Diagram (VD)-based capacitated vehicle routing model (CVRP) to deliver byproduct hydrogen from industrial areas to stations. The VD is employed to determine the assignment of HRSs in different target periods. Finally, we propose a modified branch-and-cut (BC) algorithm to solve the VD-based CVRP, which significantly outperforms commercial solvers in both speed and solution quality. Through sensitivity analysis, we identify critical factors impacting overall cost and hydrogen utilization. Tested on real and benchmark datasets, our algorithm increases byproduct hydrogen utilization by over 10% overall, reaching up to 70% in key industrial areas, while also achieving maximum path and flow coverage.</div></div>","PeriodicalId":47824,"journal":{"name":"International Journal of Sustainable Transportation","volume":"19 9","pages":"Pages 777-799"},"PeriodicalIF":3.9,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144907862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines how consumers’ emotional acceptance of transport policies—specifically, the anticipated pride and guilt-relief associated with the policies shape their intention to adopt sustainable transport. Using the case of Sweden’s environmental transport policy aimed at achieving fossil fuel independence by 2030, we surveyed 342 adults and analyzed the data using structural equation modeling. Our findings reveal that emotional acceptance of the policy significantly increases the likelihood of adopting sustainable transport (i.e. willingness to adopt an alternative fuel vehicle). Policy-related emotions enhance individuals’ perceptions of the policy’s effectiveness and foster greater support, which in turn promotes the adoption of sustainable transport options. These insights offer valuable guidance for policymakers: by complementing structural measures (such as subsidies and infrastructure investments) with communication strategies that evoke positive emotional responses, it is possible to strengthen public support for environmental transport policies and accelerate the uptake of sustainable transport.</div></div>","PeriodicalId":47824,"journal":{"name":"International Journal of Sustainable Transportation","volume":"19 7","pages":"Pages 587-596"},"PeriodicalIF":3.1,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144614107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
