In downtown or central business districts (CBDs), car commuters either pay for parking themselves (self-paid, SP) or have it covered by their employers (employer-paid, EP). However, the extent to which these groups will value their travel time (VOT) and whether they will engage in empty cruising cost to avoid parking costs in an AV era remain unexplored. This study addresses these gaps through an online stated preference survey in Melbourne, Australia, employing a discrete choice experiment and mixed logit modelling. Findings reveal that SP commuters would value travel time at 14.9 $/hr in private AVs, compared to 22.2 $/hr in conventional cars (CARs), while EP commuters’ VOT would be higher, at 24.3 $/hr for private AVs and 28.2 $/hr for CARs. SP commuters will experience a 33 % VOT decrease in AV travel compared to CAR travel, whereas EP commuters will experience a 14 % VOT reduction. These results indicate a significant decline in VOT for AV travel, particularly among SP commuters. The findings provide critical insights for transport practitioners in travel demand forecasting, transport modelling, parking policies and cost-benefit analyses. Policymakers can leverage these insights to assess the potential travel benefits of AV adoption and make informed decisions regarding infrastructure investments to support a sustainable AV future.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"173 ","pages":"Article 103807"},"PeriodicalIF":6.3,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145061105","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 delves into the spatial efficiency of MPTHs by considering three dimensions: intercity travel network characteristics, urban development features, and the connectivity between MPTHs and urban facilities. An evaluation index system consisting of 22 indicators was constructed for MPTHs within urban agglomerations. Gaussian Mixture Clustering was employed to conduct a detailed classification of the development of these MPTHs. A ‘Node-Place-Connectivity’ coupling coordination model was proposed to assess the spatial efficiency of them. Using the Beijing-Tianjin-Hebei urban agglomeration as a case study, the spatial efficiency variations among MPTHs were examined. The results indicated that the efficiency of MPTHs and the coupling coordination degree are divided into 12 classes. Highly balanced MPTHs were concentrated in Beijing, showcasing a monocentric regional structure within the urban agglomeration. Good coordinated MPTHs were strategically located in the main urban areas of cities such as Tianjin, Shijiazhuang, and Baoding, potentially fostering a polycentric urban structure within the urban agglomeration. The coordination and balance of MPTHs gradually decreased from the main urban areas to the periphery, forming a distinct concentric distribution pattern, which was particularly evident in cities like Beijing, Tianjin, and Shijiazhuang. In the marginal areas of cities and urban agglomerations, the efficiency of MPTHs was relatively low, and these MPTHs should be further developed to promote the fairness of socio-economic development in urban agglomerations. This method can serve as a decision-making tool for the planning of MPTHs.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"173 ","pages":"Article 103811"},"PeriodicalIF":6.3,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145096369","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}

However, research on when to install scrubbers and how key factors affect installation remains limited. This study addresses that gap by applying a time-varying survival analysis to investigate the determinants of scrubber adoption in container ships. Using data from 4492 container ships built between 2000 and 2023, we examine how ship characteristics (e.g., age, size, fuel type), market features (e.g., shipbuilder and ship operator), and policy environment (e.g., IMO regulation, flag) influence the timing and likelihood of scrubber adoption. The results show that by the end of 2023, approximately 27.5 % of container ships have been equipped with scrubbers, with the adoption rate significantly accelerating after 2019. Among all influencing factors, fuel type determines the major part of a ship's operating cost and shows the strongest statistical association with scrubber adoption, highlighting the centrality of cost-benefit tradeoffs in compliance decisions. Ship age is the second important factor and shows a negative impact, while IMO regulation is the third important factor. Ship size, operator, flag, and builder also have significant but more moderate influences. The results also reveal important temporal dynamics in scrubber technology diffusion. The effect of IMO regulation decays exponentially, while the effect of fuel type decays linearly, indicating that scrubber adoption decisions have complex temporal dynamics. These findings extend our understanding of scrubber technology diffusion in maritime transportation, highlighting the dynamic nature of adoption drivers and the interaction between technical, economic, and regulatory factors.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"173 ","pages":"Article 103810"},"PeriodicalIF":6.3,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145057365","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 examines the impact of geopolitical tensions on port-level carbon emissions using a monthly panel dataset covering 269 container ports across 40 countries and regions from 2016 to 2023. Employing a system generalized method of moments (SYS-GMM) estimator, we find that heightened geopolitical risks significantly increase carbon emissions at ports. A key mechanism underlying this relationship is that geopolitical tensions disrupt the vessel arrival schedules, which reduces port efficiency, and consequently increases emissions from ships at berth. Further heterogeneity analyses reveal that the environmental impact of GPR is more pronounced at ports serving larger container vessels, as these ports are typically involved in long-haul routes that are more exposed to geopolitical disruptions. In contrast, the impact is less significant at ports with fewer calling carriers, likely because dominant shipping lines tend to internalize the costs of inefficient berthing by smoothing vessel arrival times. This study provides novel empirical evidence on the environmental consequences of geopolitical shocks in the maritime sector, offering actionable policy insights for risk-sensitive and sustainable port governance.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"173 ","pages":"Article 103809"},"PeriodicalIF":6.3,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145049751","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}

In which, the industrial structure servitization represents the upgrading of industrial structure towards tertiary industry. Using data from 278 Chinese cities over a span of 19 years, we developed and employed an improved synthetic control method (SCM) and staggered SCM for our empirical investigations. The results indicate that HSR generally facilitates the upgrading of a city's industrial structure. However, the effects of HSR on industrial structure servitization tend to fade quickly, while the impacts on improving industrial labor productivity are more persistent.
