This study adopts an innovative approach by analyzing 41 h of video interviews with 2101 EV owners from a short video platform. Utilizing the Latent Dirichlet Allocation (LDA) model, topics of concern for EV owners were identified, followed by sentiment analysis supported by a large language model (LLM) and random forest model. The results indicate that 1) “After-sales &amp; Brand (19.75 %),” “Performance Experience (25.63 %),” “Functionality &amp; Comfort (31.76 %),” and “Car Cost (22.86 %)” are the four main concerns of EV owners. Notably, concern for car costs is rising, while after-sales service is decreasing. 2) While EV ownership is mostly male, female owners exhibit a higher percentage of positive sentiment, with 47.16 % compared to 36.81 % for male owners. 3) “Functionality &amp; Comfort” is the key satisfaction factor for both genders, then women prioritizing “After-sales and Brand” and men prioritizing “Performance Experience” as secondary concerns.

Rainstorm warning is an important strategy for mitigating the impacts of flood-related disasters. However, the influence of rainstorm warnings on travel decisions, particularly through the lens of accessibility perception, has received insufficient attention in the existing literature. This study aims to investigate how commuters' perceptions of accessibility are shaped, and how these perceptions influence travel adaptations under rainstorm warnings. We proposed an integrated conceptual model based on the framework of the Protective Action Decision Model (PADM). The model consists of a four-stage social-psychological process: perception of warning credibility, travel risk perception, self-efficacy perception, and accessibility perception. An internet-based survey with 1563 respondents were collected for model analysis during the rainy season in Shanghai, China. The results show that commuters with lower socio-economic status tend to exhibit lower trust in warning credibility, which correlated with higher risk perception, decreased self-efficacy, and lower perceived accessibility. Besides, subway, bus, and e-bike commuters generally reported lower perceived accessibility compared to car commuters. The results further reveal that perceived accessibility was positively correlated with the intention to travel and negatively correlated with the propensity to mode shifts, though it showed limited impacts on departure time choice. These results may benefit us to better understand commuters’ travel behavior change and enhance emergency preparedness under rainstorm warnings.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"167 ","pages":"Pages 276-294"},"PeriodicalIF":6.3,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143776362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 uses the Logarithmic Mean Divisia Index (LMDI) method within the Kaya identity to analyze the historical trends and future projects in carbon emissions of international shipping from 2010 to 2050, focusing on main driving factors. The findings reveal that as emission regulations tighten, global economic growth and expanding seaborne trade are likely to drive total carbon emissions upward. However, the improvements in carbon intensity and energy efficiency exhibit a downward trend. Among these scenarios, the net-zero decarbonization pathway emerges as the most effective, achieving reductions in carbon emissions of 92.15 % and 40 % by 2050 compared to the business-as-usual and industrial pathways, respectively. Regional analysis indicates that Europe has effectively managed emissions in line with stringent regulations, whereas emissions in Asia and Oceania have increased due to the rapid growth of seaborne trade. For the ship type, oil tankers and bulk carriers are identified as the largest contributors to emissions, reflecting their dominant role in global trade volume.

Using a computable general equilibrium model, this study evaluates the effect of renewable electricity deployment and terminal electrification on transportation sectors' carbon emissions in China and reveals their synergy effect. It contributes to the existing literature by revealing how the synergy effect enhances the carbon reduction effects of renewable electricity deployment and terminal electrification in transportation sectors. This study finds that renewable electricity deployment has a double-dividend effect in reducing carbon emissions in transportation sectors and improving their output value, with significant sectoral heterogeneity. Terminal electrification reduces carbon emissions in all transportation sectors, while it causes some damage to their output value. The synergy effect between these policies would enhance the double-dividend effects of reducing transportation sectors’ carbon emissions and benefiting their output value, especially for those with lower electrification rates. Only the synergy effect would mitigate 7.62–42.88 Mt CO₂ of carbon emissions in transportation sectors by 2060, accounting for 1.69–9.53% of total carbon emission under the baseline scenario. We suggest that this synergy effect should be recognized as a key strategy for reducing carbon emissions in the transportation sector.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"166 ","pages":"Pages 135-147"},"PeriodicalIF":6.3,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143601597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Different from the sea waterway, the navigable ship size in an inland river corridor is restricted by the waterway depths in the plentiful and drought periods. This paper deals with the design issue of ship fleet size in an inland river corridor with seasonal change in waterway depth using a vertical structure model. The interactions among consignors, competitive carriers and a public port operator over plentiful and drought periods are considered in the proposed model, together with the impacts of seasonal waterway depth on the ship fleet size. The consignors aim to minimize transport cost by choosing transfer ports in each period. The competitive carriers are intended to maximize their own net profit by determining the shipping freight rates in each period and the ship fleet size (ship frequencies and composition of ship size) over a given time horizon. A public port operator, as an agent of the government, decides the port service charges in each period to maximize social welfare over the given time horizon. The effects of the ratio of drought period duration to plentiful period duration (duration ratio), the ratio of small ship size to big ship size (ship size ratio), and the actual cargo load of big ship in the drought period on the stakeholders and the system are investigated. The results show that: (i) the government always tends to subsidize the carrier at each port in the plentiful period for a large duration ratio, but to subsidize the carrier at its competitive port in the drought period for a small duration ratio and a low cargo load of a big ship at each port; and (ii) a single big (or small) ship type strategy will underestimate (or overestimate) the ship fleet size for a low cargo load of a big ship in the drought period. The method proposed in this paper can serve as a useful tool for the fleet size plan for the carriers and for port regulation for the government so as to achieve a “win-win-win” outcome among consignors, carriers and port operator.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"166 ","pages":"Pages 108-123"},"PeriodicalIF":6.3,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143601595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 investigates the elasticity of air travel demand in Africa, focusing on the influence of socioeconomic factors and exploring non-linear dynamics. Our findings reveal that income and wealth are robust determinants of air travel demand, with higher levels of both leading to increased demand across all models. Education and exchange rates also positively impact air travel, while inflation exerts a negative influence. Notably, country size and infrastructural development emerge as significant factors, reinforcing the importance of geographic scale and infrastructure in shaping air travel patterns. Additionally, our analysis uncovers non-linear dynamics, particularly the diminishing returns of rising income and fuel prices on air travel demand. The results highlight a complex relationship where initial increases in income and fuel prices boost demand, but this effect wanes as these factors continue to grow. The interaction effects show that tourism amplifies income's impact on air travel, while high greenhouse gas emissions and aviation fuel prices, coupled with exchange rate volatility, hinder infrastructural benefits, reducing demand. These insights suggest that policymakers should consider these dynamics and prioritise sustainable infrastructural development and targeted economic policies to foster growth in the African air travel sector.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"166 ","pages":"Pages 179-188"},"PeriodicalIF":6.3,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143629187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
