Existing research mostly uses aggregate data of migrant workers, which disregards individual behavioral decision-making variations. To fill this gap, this study aims to delve into the impact of HSR on migrant workers' intercity employment location choice in China using data from the China Migrant Dynamics Survey (CMDS). This paper develops a theoretical model that combines income growth, unemployment rates, information constraints and intervening costs to investigate how HSR impacts migrant workers' decision, complemented by an empirical analysis using a conditional logit model and investigating individual heterogeneity. Relying on a sample of 89,801 migrant workers over the period 2011–2017, the results indicate that HSR significantly increases a city's allure for migrant workers, with HSR accessibility exerting a more profound influence compared to HSR connectivity. Migrants who are female, young (aged 16 to 29), unmarried, having no kids, working in secondary industry or foreign enterprises, with non-urban hukou or crossing provinces demonstrate a heightened sensitivity to both HSR connectivity and accessibility. Furthermore, the willingness to pay of migrant labor is highest for the operation of HSR, followed by improvements in accessibility, and then by enhancements in connectivity. By considering these diverse factors, our study provides a more nuanced understanding of how HSR shapes employment location choices for migrant workers in China, highlighting the significance of accessibility and connectivity in determining the labor migration.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"166 ","pages":"Pages 65-86"},"PeriodicalIF":6.3,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143579194","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 the second step, a qualitative analysis focused on the regulatory and policy context in which five MASs (Seoul, Brussels, Shanghai, Miami, and Montreal) were developed. This helps determine how much airports cooperate or compete with each other. Empirical evidence from 37 two-airport MASs worldwide suggests that inter-airport matches occur on less than 20% of routes that offer more than 40% of seats.

Accounting for the COVID-19 pandemic and the US‒China trade war, this study uses data envelopment analysis (DEA) with an assurance region (AR) to measure the efficiency of 19 international airports from 2017 to 2021 and applies the Malmquist productivity index (MPI) to analyze productivity changes. Airport selection is based on Skytrax rankings, with inputs including runway length, terminal area, and operational expenses, and outputs including the number of passengers, cargo volume, and total revenue. Key findings indicate that the Seoul Incheon (ICN), Hong Kong (HKG), London Heathrow (LHR), Taiwan Taoyuan (TPE), and Jakarta (CGK) airports were efficient, suggesting disparities with the Skytrax rankings. The MPI decreased by 16% across the 19 airports over the study period, with volatility and a notable decline. Noteworthy progress has occurred at the Copenhagen (CPH), HKG, CGK, and Rome Fiumicino (FCO) airports. The geometric mean of the MPI for 2020–2021 decreased to 0.514, indicating that COVID-19 had a significant impact on airport productivity, with technological advancements driving productivity shifts. Furthermore, a management decision matrix classified the 19 airports into seven categories based on their relative aggregate efficiency (AE) and efficiency change (EC) scores, with HKG, CGK, and ICN demonstrating high competitiveness and rapid progress; strategies for improving or maintaining a competitive advantage in each category are presented. The findings of this paper can help airport managers understand relative efficiency and improvement directions, serving as a reference for future strategies.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"167 ","pages":"Pages 78-90"},"PeriodicalIF":6.3,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143738458","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}

It is imperative for both government entities and transport operators to continuously assess and enhance the performance of road transportation to effectively meet the needs of passengers and freight stakeholders. This research aims to provide road transportation policymakers with a novel and effective hybrid method that incorporates Q-methodology to address the limitations of the conventional Cross-Efficiency (CE) method, particularly by utilizing both correlated and uncorrelated perspectives. The Q-methodology enables policymakers to identify and exclude Decision-Makers' (DMs') viewpoints, including sets of cross-efficiencies with low correlations, during the analysis process. It employs factor analysis to extract consensus perspectives, thereby providing a more realistic assessment of transportation unit efficiency and reducing the likelihood of biased results. The proposed technique incorporates the Q-methodology into the double-frontier CE method, referred to as DFQCE, to enhance its effectiveness by eliminating uncorrelated viewpoints from the efficiency evaluation process. The conventional CE method utilizes both correlated and uncorrelated viewpoints, which may introduce bias into the results. Furthermore, recent critiques have emerged regarding efficiency evaluations that rely solely on the efficient frontier, as these evaluations do not take into account the assessment results of transportation units from a pessimistic viewpoint, which may differ significantly from those based on the efficient frontier. By incorporating both pessimistic and optimistic perspectives, Double-Frontier Q-based Cross Efficiency (DFQCE) aims to produce more comprehensive outcomes compared to the conventional CE method. To validate the developed methodology, the road transportation operations of thirty-one Iranian provinces are evaluated using four input and three output indicators. Loading factors of 0.7 and 0.6 are selected for the optimistic and pessimistic views, respectively, to encompass the broadest range of cross-efficiencies, accounting for 93% and 96%. To enhance the performance of provinces facing subpar conditions, policy, and theoretical implications are suggested. The findings will be of considerable significance to provincial administrators and national policymakers in road transportation, as they provide insights that can facilitate more effective management of the sector by addressing inefficiencies within the provinces.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"167 ","pages":"Pages 42-65"},"PeriodicalIF":6.3,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143715480","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}

Thus, this paper explores the significance of information sharing in particular potential requirements of spare parts replacement. We propose a novel Spare Parts Condition Sharing (SPCS) policy for airlines in AMR, aiming to better align the airline's maintenance planning and service providers' capabilities. The purpose is to enhance synchronization between planned maintenance schedules and actual service delivery time and facilitate matching between required and available spare parts inventory. Empirical analysis demonstrates substantial theoretical improvements over the baseline AMR approach, with quantifiable reductions across multiple operational metrics: ferry flights, flight cancellations, delayed flights, and severe delayed flights. Furthermore, the results indicate a significant decrease in total delay time, while incurring only a marginal increase in unutilized flying time. This paper also reveals the importance of maintaining high-quality maintenance data and illustrates enhanced cost-effectiveness through increased maintenance opportunities. This SPCS policy effectively bridges the communication gap between airlines and service providers, offering a pragmatic solution for enhancing aircraft maintenance routing planning. The improvements demonstrated in operational stability and service quality underscore the potential of industry practices advancement.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"166 ","pages":"Pages 32-49"},"PeriodicalIF":6.3,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143552806","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}

Therefore, this study aimed to scrutinize the factors affecting the taste heterogeneity of autonomous driving services. A combined method of a latent class model and a random forest was suggested to overcome the overparameterization problem in a latent class model. The proposed model allows us to consider a wide range of variables affecting mode preferences at once, while it is challenging to interpret the direction and the magnitude of impact or heterogeneity compared to the latent class model. Therefore, the Shapley additive explanations (SHAP) was employed to interpret the results of the random forest. To investigate a variety of factors, two datasets, which are data including stated choice preferences, demographics, and attitudinal indicators from online questionnaire and regional characteristics from Statistics Korea, were combined based on the residential addresses of respondents. The latent class model revealed six classes based on transport mode preference. This suggests that there is taste heterogeneity in the preference for AMoD. SHAP analysis identified the magnitude and direction of the impact of the factors influencing taste heterogeneity for AMoD.
