However, the adoption of general policies may be ineffective due to the heterogeneous nature of user perceptions that shape transit loyalty. Specifically, service quality factors might vary markedly among captive riders and those who prefer to use transit, including choice riders and voluntary riders. In this study, we investigated the transit dependence-based segmentation in the analysis of transit satisfaction and loyalty. Employing survey data from Chicago Transit Authority (CTA) riders collected in 2022, we aimed to: (1) examine the significance of heterogeneity in transit satisfaction and loyalty across captive, choice, and voluntary riders, and (2) assess the implications of overall approach versus dependence-based segmentation approach. We developed a Partial Least Squares Structural Equation Model (PLS-SEM) and conducted Permutation Multi-group Analysis (PMGA) to assess the hypothesized heterogeneity among three rider groups. Additionally, we introduced Importance-Performance Deviation Index (IPDI) to rank the service quality aspects for improvement policies specific to each group. The proposed metric highlights the variations of prioritized factors for improvement across rider groups. Our analysis reveals that while cleanliness is the most unsatisfactory aspect for all rider groups, choice riders exhibit more dissatisfaction with cleanliness. Further, reliability, particularly in terms of waiting times and service arrivals, does not meet voluntary riders’ expectations. Moreover, comfort factors are critically unsatisfactory for captive riders, especially at stations and in-vehicle, compared to other two rider groups. These findings showcase the ramifications of adopting general policies instead of group-specific strategies. The study provides transit agencies with actionable insights to develop informed and targeted retention strategies, ultimately enhancing transit users’ satisfaction and loyalty.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"171 ","pages":"Pages 821-837"},"PeriodicalIF":6.3,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144655776","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}

Analyzing access/egress distance to station is crucial for transport planning and implementation. In the recent contexts of fast metro construction and advancing information and networking technologies, various feeder transport emerged and access/egress distances to metro extended a lot, but few studies modeled metro mode share variation by access/egress distance. To determine the focus metro catchment area for effective feeder transport allocation, this study explores the threshold range of access/egress distance by walking, biking, bus and park-and-ride. The data comes from a sampling survey of household travel in Xi'an. The results show that, within a 3-km radius of the stations, metro mode shares decrease quickly from 16-23 % to 2–3 %. Beyond this distance, the decreasing rates become quite small. The bus-metro transfer distance can be extended to 6 km in the suburbs. For the effective and economical feeder transport allocation, a 3-km radius of the station is the focus area. The average elasticity of access/egress distance to metro mode share is −0.644 and −1.445, respectively in the central urban area and the suburb, indicating a larger variation compared with the result of −0.29 in North America. The number of parking lots within 50 m of the station is a critical factor for park-and-ride. We recommend providing diverse feeder bus operations and allocating the dedicated and human-oriented walking/cycling lanes within a 3-km radius of the station. In the suburbs, feeder buses can be extended to a longer range, about 6-km radius of the station according to the local demands. We suggest providing park-and-ride facilities within 50 m of the station and simultaneously encouraging shared parking lots. These planning suggestions can promote an efficient access to metro station pattern, optimize urban transport system's performance, and ultimately, obtain the low-carbon and sustainable transport development goal.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"171 ","pages":"Pages 867-881"},"PeriodicalIF":6.3,"publicationDate":"2025-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144678870","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}

Unlike prior investigations that predominantly applied panel data methods and frequently ignored the distinct economic contexts of specific economies, this investigation adopts the refined Quantile-on-Quantile instrument. This methodology allows for examining variables’ changes within every economy individually, augmenting accuracy and providing a more insightful understanding of distinct traits of each economy. The results disclose a significant positive relationship between e-mobility technology budgets and electric vehicle stock in most analyzed countries, demonstrating particular patterns and dynamics. However, the relationship is more complex in Sweden and Norway, showing mixed results.

This study utilizes origin-destination (O-D) road express logistics flow data comprising over 1.2 million records collected over one year from 41 cities in the Yangtze River Delta region of China to estimate carbon emissions based on parcel weights and transportation distances. The total carbon emissions generated from road express logistics were estimated to be 44,268.1 tons. A spatial econometric interaction model is then utilized to explore spatial diffusion patterns and influencing factors of carbon emission intensity. The result suggests that the intra-city flow and intercity flow of carbon emissions exhibit significant spatial heterogeneity. The spatial parameters demonstrate significant spatial autocorrelation in emission intensity in outflow cities, inflow cities, and O-D city pairs. A higher proportion of secondary industry added value to Gross Domestic Product in outflow cities and more advanced digitalization level in both outflow and inflow cities increase carbon emission intensity. In contrast, higher resident income level in outflow cities and infrastructure construction level in both outflow and inflow cities decrease carbon emission intensity. The impact of digitalization on carbon emission intensity is greater than that of other independent variables, with a 1 % increase corresponding to a 2.326 % rise in carbon emission intensity.
