Therefore, many cities are exploring freight transportation infrastructure planning and management measures that minimize disruption to urban living spaces. However, progress remains limited due to an insufficient understanding of the driving factors behind truck travel demands within the city. To address this issue, this study focuses on the generation of heavy-duty truck trips and explores its spatial heterogeneity, which is of particular interest to multiple stakeholders seeking fine-grained freight traffic management. We used continuous trajectory data to extract heavy-duty truck trips and integrated multiple data sources to identify the driving factors behind urban heavy-duty truck trip generation. Results from statistical models revealed that the density of industrial, transshipping, and warehousing enterprises, along with freight hub accessibility, are influential factors in determining heavy-duty truck trip generation. Furthermore, we compared and analyzed heavy-duty truck trip generation intensity across different geographical zones and discovered that the generation intensity was unevenly distributed across space. We also found that the impact of resource processing and large logistics enterprise density on heavy-duty truck trip generation is spatially heterogeneous, with a weaker influence on producing and attracting heavy-duty truck trips in the urban core area. These findings can help local authorities in formulating fine-grained freight traffic management policies based on the freight trip generation mechanism to avoid imposing excessive burdens on logistics enterprises. This work also contributes to the development of sustainable urban freight service systems and help address the potential environmental and social issues arising from heavy-duty freight activities in suburban areas.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"164 ","pages":"Pages 60-79"},"PeriodicalIF":6.3,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143143224","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}

These revenues depend on the demand for aeronautical services, as they are intricately tied to passenger traffic. Consequently, airports have intensified efforts to boost air traffic, a challenging task given the mobility of footloose airlines. This competitive environment compels airports to adopt strategic measures with competitive pricing emerging as a critical approach in the capital-intensive airport industry. This study examines the dynamic relationships between airlines and airports, focusing on their respective bargaining positions and financial gains they extract. Using a two-tier stochastic frontier (2TSF) analysis on data for 59 U.S. airports during the 2009–2019 period, this study quantifies the gap between optimal and actual aeronautical charges while identifying determinants of bargaining power such as low-cost carrier (LCC) dominance, legacy airline hub status, proximity to competing airports, airline concentration, percentage of local passengers, and rate setting methods. Results indicate that airlines hold stronger bargaining positions with financial gains 8.4% higher than those of airports, which leads to aeronautical charges being set below optimal levels. Medium-sized airports achieve relatively higher gains compared to large airports, and airports within multi-airport systems (MAS) enjoy a greater bargaining advantage. In contrast, rival airports within a 100-mile radius reduce an individual airport's bargaining leverage, highlighting the competitive pressures faced by U.S. airports despite their public ownership. Socio-economic factors, such as tourism and foreign direct investment (FDI), significantly increase airport fees by enhancing the value of their services to airlines.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"164 ","pages":"Pages 80-91"},"PeriodicalIF":6.3,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143143227","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, the reaching of a ride-sharing transaction depends on the joint decision-making of passengers and ride-hailing platforms: passengers must be willing to share, which is often influenced by waiting times, described here as the willingness dependent tolerance (WDT) mechanism; the platform determines ride-sharing matching through regulating route similarity strategies. To explore how the interaction mechanisms between the two parties affect ride-sharing operations and thereby the efficiency and resilience of ride-hailing systems, this paper employs queuing theory and multi-agent approaches to build models for extensive analysis, and verifies these with actual data from Beijing. The results show that the WDT mechanism can adaptively adjust passenger choices and system operating modes in response to supply and demand changes, maintaining high efficiency and resilience of ride-sharing services during supply shortages. However, there exists a competitive equilibrium point between platform regulation and the WDT mechanism, where adjusting the route similarity standard before and after this point affects the adaptability of the WDT mechanism differently. Based on these findings, recommendations are made from the perspectives of platform operation and government management, aiming to seize the optimal moments to encourage ride-sharing, balance individual comfort with overall system performance, and optimize platform regulation effectiveness.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"164 ","pages":"Pages 27-41"},"PeriodicalIF":6.3,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143143183","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 investigates the factors influencing EV adoption intentions across different vehicle segments in Thailand by integrating the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) with government participation factors. Using data from 3770 respondents across five regions, the study employs structural equation modeling to analyze adoption patterns among passenger cars, pick-up trucks, and SUVs. The findings reveal distinct adoption patterns across segments: passenger cars are primarily influenced by Price Value (β = 0.262) and Effort Expectancy (β = 0.179); pick-up trucks show strong Performance Expectancy effects (β = 0.504) but negative Social Influence (β = −0.366); and SUVs demonstrate the strongest Performance Expectancy impact (β = 0.699) with a notable negative Price Value effect (β = −0.386). Government participation maintains consistent positive influence across all segments (β ranging from 0.101 to 0.153). Based on these findings, the study recommends a three-phase policy implementation framework emphasizing segment-specific approaches: urban-centric initiatives for passenger cars, commercial viability focus for pick-up trucks, and premium service emphasis for SUVs. This research contributes to EV adoption literature by demonstrating how adoption factors vary significantly across vehicle segments in emerging markets, challenging the one-size-fits-all approach to EV promotion. The findings provide valuable insights for policymakers and manufacturers in tailoring their strategies to different vehicle segments, particularly in emerging markets.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"163 ","pages":"Pages 408-435"},"PeriodicalIF":6.3,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143173791","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, their prevalence has created an acute safety crisis, with motorcyclists representing over 70% of road fatalities. While previous studies have examined either injury severity or fault status in isolation, the potential interdependency between these outcomes remains poorly understood. This study addresses this gap by investigating motorcycle crash injury severity through both direct effects and indirect effects mediated through riders' at-fault status. This study examines motorcycle crash injury severity by considering both direct effects on outcomes and indirect effects mediated through riders' at-fault status. Analyses were conducted for three timeframes—2017–2018, 2019, and 2020—to capture potential temporal instability. A recursive bivariate modeling framework with random parameters was adopted to address unobserved heterogeneity and endogeneity between fault likelihood and crash severity outcomes, revealing key demographic, behavioral, and infrastructural predictors of fatal injuries. Findings indicate that younger riders, nighttime conditions, and high-risk behaviors (e.g., speeding, and alcohol use) increase the probability of being at fault. Meanwhile, factors such as being male, older, riding without a helmet, traveling against traffic, and riding at night significantly raise fatal injury risks. Although at-fault data provide valuable insights, they must be interpreted alongside roadway conditions, as Thailand's infrastructure offers limited protection for motorcyclists. Accordingly, this study recommends an integrated approach that combines improved infrastructure (e.g., motorcycle-friendly barriers and segregated lanes), robust education initiatives (targeting speed, helmet use, and alcohol awareness), and enhanced enforcement of traffic regulations. Implementing or enhancing licensing standards—such as a Graduated Licensing Scheme—can help curb risky behaviors and foster safer riding practices among young riders. These evidence-based recommendations can help policymakers develop more effective mitigation strategies to reduce the number of severe and fatal motorcycle-related crashes.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"163 ","pages":"Pages 370-383"},"PeriodicalIF":6.3,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143173795","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}
