Due to limitations in research, development time, and production costs, new energy aircraft and sustainable aviation fuel cannot be widely adopted in the short term. As a result, carbon offset is currently the primary method to balance aviation carbon emissions. Despite the introduction of carbon offset programs by most airlines, passengers' willingness to pay (WTP) remains low. This study aims to explore what incentive mechanism is conducive to enhancing passengers' WTP for aviation carbon offset. We propose three categories of incentive mechanisms: material incentive mechanism (MIM), emotional incentive mechanism (EIM), and hybrid incentive mechanism (HIM), with the latter further subdivided into four types based on incentive form and seasonal dimensions. A questionnaire survey is conducted to collect decision-making data on passengers' participation in aviation carbon offset. Based on this data, a public goods game (PGG) model is built to explore the impact of different incentive mechanisms on passengers' WTP. The simulation results indicate that: (i) Incentive mechanisms increase passengers' WTP compared to no incentive. (ii) MIM and first material incentive followed by emotional incentive (HIM<sub>2</sub>) are the most effective. (iii) The use of purely material incentives has a limited effect on improving cooperation frequency (<em>f</em>). These findings provide theoretical guidance and strategic recommendations for airlines in implementing carbon offset programs.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"181 ","pages":"Article 104087"},"PeriodicalIF":6.3,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147385982","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 harnesses mobile signaling data and applies an enhanced Nonnegative Matrix Factorization (NMF) technique to uncover spatiotemporal travel patterns within the Yangtze River Delta urban agglomeration. The analysis identifies three distinct spatiotemporal travel patterns: leisure and business dual-driven travel (LBT), outbound tourism and family visits (OTV), and return trips related to tourism and family visits (RTV). In addition, the Quadratic Assignment Procedure (QAP) model traditionally utilized in social network analysis is employed to examine the factors influencing these travel patterns. The findings indicate that macroeconomic factors, spatial proximity and travel convenience uniformly influence all of the identified patterns, whereas factors related to Work-life balance and tourism and leisure exhibit varying degrees of significance across the patterns. The results further demonstrate that the critical influencing factors are aligned closely with the spatiotemporal distribution characteristics of each pattern, corroborating the efficacy of the proposed methodology in mining and analyzing spatiotemporal travel patterns.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"181 ","pages":"Article 104024"},"PeriodicalIF":6.3,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147386097","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 these barriers and identifies policy support needs to facilitate accelerated BET adoption. Drawing on four datasets from Germany and Sweden, including surveys, interviews, and workshops with more than 200 transport companies, this research compares the experiences of early adopters with the perceived barriers of the early majority. Findings reveal that the early majority perceives the issues encountered by early adopters during operation, such as charging infrastructure limitations, range constraints, and economic uncertainties, as continuous risks that reinforce their hesitancy toward adoption. Additionally, we uncover new barriers not extensively discussed in existing innovation diffusion literature: regulatory uncertainty and contested technological pathways.

Yet, no study that looked at the integration of accessibility in policy documents has assessed accessibility across documents published by different organization types and government levels. This study addresses this gap by examining how different documents define accessibility, whether they distinguish it from mobility, and the degree to which accessibility objectives are supported by indicators. We assessed 40 Canadian documents from land use and transport planning authorities, municipalities, and transit agencies using a 20 binary questions structured content analysis framework complemented by a qualitative content analysis. We find that municipal documents score higher than documents produced by transit agencies, especially in recent years. Further, the highest accessibility score (90%) is obtained by a municipal integrated land use and transport plan. In contrast, no transit agency document scored above 50% nor includes accessibility indicators. Many documents also reveal inconsistencies between stated objectives, governance structures, and implementation pathways.
