However, the contributions of transportation electrification to carbon emissions (CRE) depend on the degree of power grid decarbonization. This study employed the Kaya Identity, the Logarithmic Mean Divisia Index (LMDI) model, and Moran's Index to examine CRE and its spatial clustering characteristics across China's seven power grid regions from 2004 to 2022, covering 30 provinces. Results indicated that the transportation electrification rate (EE) remained stable in the early years but increased gradually after 2016, reaching 12.35 % by 2022. Transportation electrification primarily impacts carbon emissions through three aspects: electricity substitution, electricity decarbonization, and energy efficiency improvement. Transportation electrification resulted in an additional 9.94 Mt of carbon emissions from 2004 to 2022, with the electricity substitution effect being the primary contributing factor. Most provinces have not achieved carbon reductions through transportation electrification. This outcome is mainly because these provinces have placed greater emphasis on the quantity of transportation electrification (rapid EE increase) rather than its quality (lagging grid decarbonization). Furthermore, regarding spatial distribution, CRE exhibits a clear pattern of “high in the north and low in the south”, indicating spatial clustering. This study provides valuable insights for advancing transportation electrification strategies.</div></div>","PeriodicalId":47810,"journal":{"name":"Research in Transportation Economics","volume":"115 ","pages":"Article 101698"},"PeriodicalIF":3.4,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145840227","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}

These factors and demographics were included in an ordered logit model to assess their impact on perceived security. Results show gender is the strongest predictor, with women reporting lower security than men. However, men also feel insecure, especially at night or outside urban areas. These findings underscore the need to combine gender-neutral and gender-sensitive strategies to ensure fairness while addressing the diverse security needs. Other significant variables include age, past harassment experience, media exposure, and family norms. Those with very low perceived security are less responsive to interventions than those with moderate or higher security. We also evaluated user preferences for a range of proposed measures. Cameras and tracking received strong support, with many expressing a willingness to pay for increased security. Security apps showed promise, but users stressed the need for better privacy, preventive functions, and real-time response.</div></div>","PeriodicalId":47810,"journal":{"name":"Research in Transportation Economics","volume":"115 ","pages":"Article 101689"},"PeriodicalIF":3.4,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145685061","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}

Since the high uncertainty in the VOTT often arises from substantial preference heterogeneity across individuals, this paper developed a mixed multinomial Probit model with correlated error terms to analyze the impact of SAV service on commuters’ mode choice and the VOTT in Shanghai, China. The results show that, relative to the VOTT derived from revealed preference data, the VOTT for private cars based on stated preference data after the introduction of SAV services shows a slight increase, while the VOTTs for taxis and public transit remain largely unchanged.

To address gaps in current research, this paper assesses the impact of supporting policies and dynamic adoption of UCCs by stakeholders. An agent-based simulation model is developed to replicate retailers' selection of carriers based on generalized logistics costs (GLCs), and carriers' scheduling of truck operations in response to delivery demands. Three policy categories — operational subsidies, traffic regulations, and parking management — are evaluated. With an UCC serving clothing retailers in Shanghai's Wujiaochang CBD as the study case, data from various sources is used to model the agents. Results indicate that standalone UCCs implementation yields limited effectiveness. Operational subsidies exert the most significant impact, whereas traffic and parking policies provide moderate benefits. The optimal policy package includes a substantial, evenly distributed subsidy over the subsidy period, a delayed traffic restriction start time, and a 25 % parking fee discount for UCC trucks. This policy package produces a synergistic effect, significantly reducing vehicle kilometers traveled (by 21.19 %) and implicit logistics costs (by 50.38 %). These insights inform effective policy design and offer a valuable decision-support tool for cities considering UCCs implementations.</div></div>","PeriodicalId":47810,"journal":{"name":"Research in Transportation Economics","volume":"116 ","pages":"Article 101719"},"PeriodicalIF":3.4,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146189260","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}

Using structural equation modeling and multi-group analysis of data from 1677 intercity railway users across Thailand's seven regions, this research investigates the moderating roles of transport modes, station location, age, gender, and income level in shaping how railway inequality dimensions influence accessibility barriers, safety concerns, and affordability challenges.

These findings challenge traditional approaches to transport equity that emphasize demographic targeting, instead advocating for universal improvements in multimodal transport integration and first-and-last-mile connectivity.

Case reviews focussed on: the circumstances of the devolution; any associated vertical separation and privatisation; impacts; and any subsequent policy reversals.
