The extent to which the county authorities have managed to implement living safety management systems and maintain their key road safety roles differs substantially.

However, the intricate and unpredictable nature of mobility dynamics often obstructs efforts to promote sustainable travel behaviors. While hybrid choice models (HCMs) incorporating latent variables prove invaluable in analyzing travel behavior, there remains a critical need for further exploration into effectively managing these variables. Typically assessed at singular time points, these variables pose challenges in analyzing individual characteristics based on their fluctuations. Moreover, deriving actionable policy implications from HCMs is challenging due to the inherent nature of psycho-attitudinal variables, which exhibit limited responsiveness to alterations in alternatives. Only a significant disruptive event could induce notable shifts in individuals’ psycho-attitudinal characteristics. The objective of this paper is to investigate two aspects: i) to study if and how norms, intentions and perceived behavioral control change after a strong shock such as the pandemic, and ii) to analyze the differences in the HCMs results estimated by using data collected before and after the shock. The study involves a panel dataset gathered during a VTBC Program which involved three phases, two of which before and straight after the first lockdown. Our results show that norms were less impacted by COVID-19 and lost importance post-lockdown. There was a notable decline in the intention to use sustainable modes and an increase in car usage, with significant differences in perceived behavioral control between those who maintain and those who change their transport modes.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"28 ","pages":"Article 101265"},"PeriodicalIF":3.9,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142578399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study employs Partial Least Squares Structural Equation Modelling (PLS-SEM) on a sample of 110 tanker drivers at a major South African trucking company to model the relationship between safety climate and two classes of aberrant driving behaviours – errors and violations. A multilevel model measuring safety climate using organisation-level safety climate (OSC) and group-level safety climate (GSC) is followed, with OSC fully mediated by GSC in its effect on driver behaviour. The findings show safety climate has a significantly larger impact on driving violations than errors, as safety climate affects the driving behaviour largely through safety motivation, which has a greater impact on categorically intentional violation behaviours, as opposed to habitual, unintentional errors. The study also demonstrates that safety climate explains a larger portion of the variation in violations than errors, suggesting that violations may be more sensitive to changes in safety climate, supervisory behavioural integrity, and safety motivation. Interventions leveraging safety climate may thus be more effective at reducing violations than errors. Future research should investigate the precursors to driving errors, as addressing these may require remedial training rather than changes in safety climate to achieve substantial improvements.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"28 ","pages":"Article 101272"},"PeriodicalIF":3.9,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142664271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study compared the classification accuracy of modeling approaches using receiver operating characteristic analysis. By analyzing three years (2015–2017) of pedestrian crashes in Mashhad, this study identified risk factors associated with higher severity of vehicle–pedestrian crashes at intersections. The results show that models incorporating the heterogeneity effect, such as the cluster-aggregated model and the random parameter model, have higher classification accuracy for crashes than models that do not consider heterogeneity.

Despite government efforts, BEV adoption in Thailand remains below expected levels. This study identifies and evaluates the barriers to BEV adoption through a comprehensive survey administered to 3,069 respondents across Thailand. Employing Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA), the study categorizes and quantifies these barriers, offering insights into the factors that hinder consumer acceptance of BEVs. The results reveal that ’Vehicle attributes’, including concerns about efficiency, range, and reliability, is the most significant barrier for both BEV and ICE users. However, the order and strength of subsequent barriers differ between these groups. For BEV users, ’Public Data’ and ’Lack of Benefits’ follow as major concerns, while ICE users prioritize ’Financial Barriers’ and ’Consumer Concerns’. Notably, BEV users generally perceive these barriers more strongly across all categories. Based on these findings, this study proposes targeted policy recommendations aimed at addressing these barriers for both current and potential BEV users. Enhancing vehicle attributes characteristics, expanding charging infrastructure, implementing educational campaigns, revising fiscal incentives, and rebranding EVs through effective marketing strategies are critical measures suggested. These interventions are designed to align with both BEV and ICE user expectations and catalyze the broader acceptance and adoption of BEVs in Thailand.
