Thus, this study examines the specific dimensions of trust necessary to accept and adopt ATs. We propose a multidimensional model of trust that integrates dispositional, situational, and learned trust across social, data, and technical levels. Using a two-stage approach comprising confirmatory factor analysis and structural equation modelling, we empirically validate these different trust dimensions through a two-point-in-time survey conducted in Germany. The results indicate that each trust dimension positively influences risk behaviour, with situational technical trust having the most substantial influence. Contrary to previous assumptions, perceived relationship risk does not significantly reduce trust, and perceived situational risk does not moderate the trust–risk relationship. Risk propensity is found to be a strong predictor of risk-taking behaviour. Our research provides valuable insights for developers, providers, and policymakers to promote trust and support the introduction of ATs.</div></div>","PeriodicalId":48355,"journal":{"name":"Transportation Research Part F-Traffic Psychology and Behaviour","volume":"113 ","pages":"Pages 357-373"},"PeriodicalIF":3.5,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144067981","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}

We tested this instrument on a German sample of pedestrians (<em>n</em> = 136), considering their individual demographic characteristics, and level of affinity for technology interaction. A four-step approach was adopted to analyze the data. First, a principal component analysis was performed to reduce the number of items, exploring the sources of variation in the dataset. Second, the principal components were subjected to a confirmatory factor analysis to investigate the validity and reliability of the proposed measurement model. Third, structural equation modeling was conducted to estimate the path relationships between our constructs. The study has revealed differences between the effect sizes and significance levels of the factors influencing pedestrians’ AVA. The AVA by pedestrians was most strongly influenced by affinity for technology interaction (i.e., extent to which the individual actively approaches or avoids the interaction with new systems), performance expectancy (i.e., extent to which the individual believes that using the system will support them in achieving gains in the performance of the task) and social influence (i.e., extent to which the individual believes that people important to them think that the individual should perform the behavior). Male pedestrians were more likely to accept AVs. We also revealed significant interaction effects of age on the variables in our model. With this work, we have contributed to the development and validation of the Automated Vehicle Acceptance Questionnaire for Pedestrians (AVAQ-P).

It also examines how TOT influences driving performance and safety metrics, such as, acceleration, lane position, and crash rates after TOR. Using the PRISMA framework, 51 studies were systematically reviewed. Meta-regression and sensitivity analyses were conducted to quantify the effects of key factors on TOT. Heads-Up Displays (–14.8 %), TOR alerts (–64.7 %), and higher traffic volumes (–10.8 % per increase from free flow to high traffic volume) were associated with shorter TOT, while urgent TORs (+36.7 %), unequal gender distribution (+14.3 %), increased time budgets (+1.8 % per second), and additional lanes (+14.2 % per lane) were associated with longer TOT. TOT varied significantly across road types and traffic volumes, with highways exhibiting longer TOT and high traffic volumes resulting in shorter TOT, likely due to heightened driver attentiveness. Driving performance metrics revealed significant correlations between shorter TOT and higher maximum longitudinal and lateral accelerations, greater lane variability, and a moderate increase in crash rates, highlighting potential safety concerns.

This shift of driving responsibilities from human drivers to automated systems raises concerns about accountability, particularly in scenarios involving unexpected events. To address these concerns, the concept of meaningful human control (MHC) has been proposed. MHC emphasises the importance of humans retaining oversight and responsibility for decisions made by automated systems. Despite extensive theoretical discussion of MHC in driving automation, there is limited empirical research on how real-world partially automated systems align with MHC principles. This study offers two main contributions: (1) an empirical evaluation of MHC in partially automated driving, based on 103 semi-structured interviews with users of Tesla's Autopilot and Full Self-Driving (FSD) Beta systems; and (2) a methodological framework for assessing MHC through qualitative interview data. We operationalise the previously proposed tracking and tracing conditions of MHC using a set of evaluation criteria to determine whether these systems support meaningful human control in practice. Our findings indicate that several factors influence the degree to which MHC is achieved. Failures in tracking—where drivers' expectations regarding system safety are not adequately met—arise from technological limitations, susceptibility to environmental conditions (e.g., adverse weather or inadequate infrastructure), and discrepancies between technical performance and user satisfaction. Tracing performance—the ability to clearly assign responsibility—is affected by inconsistent adherence to safety protocols, varying levels of driver confidence, and the specific driving mode in use (e.g., Autopilot versus FSD Beta). These findings contribute to ongoing efforts to design partially automated driving systems that more effectively support meaningful human control and promote more appropriate use of automation.</div></div>","PeriodicalId":48355,"journal":{"name":"Transportation Research Part F-Traffic Psychology and Behaviour","volume":"113 ","pages":"Pages 213-236"},"PeriodicalIF":3.5,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143921967","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}
