However, vehicle-centric urban planning has resulted in lower levels of AT in many countries. Studies evaluating the effects of AT on society and ecosystems tend to highlight the tangible benefits over the intangible ones, potentially missing the broader advantages of AT. Furthermore, there is a considerable difference in adopting AT promoting measures and policies between the developing and the developed worlds. There are several economic methods to evaluate various aspects of AT, among which cost-benefit analysis (CBA) is widely used. However, for a more informed decision-making by political leadership, it is essential to adopt a comprehensive evaluation methodology that covers the full spectrum of costs and benefits associated with AT, hereby enabling better urban transport planning.

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.

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 CO<sub>2</sub> of carbon emissions in transportation sectors by 2060, accounting for 1.69–9.53% of total carbon emission under the baseline scenario.
