Combining a key informants approach with a qualitative descriptive research design, semi-structured interviews with 20 police leaders in Ontario, Canada, explored methods for prioritizing and implementing road safety initiatives, perceived effectiveness of road safety measures, and support for and barriers to TLE from different stakeholders. Interview transcripts were thematically analyzed. Findings highlighted that police leaders view TLE as effective at enhancing traffic safety and as a key policing priority. Leaders acknowledged diverse viewpoints of TLE among frontline officers, citing several reasons for those less engaged with TLE and emphasizing the important role played by supervisory officers. Most police leaders perceived support for TLE from relevant stakeholders including municipal representatives, Ministry of Transportation Ontario, and the judicial system. Even the general public was viewed as supportive, though several exceptions were cited. A shift toward evidence-based policing and data-driven TLE was noted. Challenges to TLE included competing policing priorities and limited financial resources. Police leaders cited a clear need for additional equipment used for TLE activities, more officers to conduct these activities, and more training for these officers. Together, this research addresses an important gap in the road safety literature and offers actionable insights to enhance TLE in Ontario and similar jurisdictions.

However, ACC systems vary across vehicle models and thus drivers likely have different experiences of, and opinions on, this technology. This study explored drivers' experiences of ACC, including safety perceptions, awareness of its limitations, learning about ACC, and changes to driving behaviour. Forty-three Queensland drivers (19–70 years) participated in one-on-one interviews. Template analysis recognised four themes: 1) knowledge, 2) perceived value, 3) driving variations, and 4) ACC acceptance compared to other technologies. Key findings included that many participants find ACC gap distances too long and reported selecting the shortest option, principally for avoiding other vehicle cutting in from of them. Several other issues with the technology were described, including delayed reactions, and incorrect speed changes. In addition, drivers were unaware of several limitations, yet common limitations (e.g., rain) were recognised. ACC was perceived as safe, useful, and beneficial to control speed and avoid infringements, while trust varied from complete trust to no trust. Further, participants described that ACC reduced aggressive driving and increased patience on the road, and many described changes to attention when using ACC. ACC acceptance was common, particularly above other vehicle technologies. These findings suggest that increasing education (e.g., via social media campaigns) and training (e.g., through dealerships) for ACC may be beneficial to promote understanding of its functions and limitations, particularly in relation to gap distances. Future research may also explore if ACC use is associated with less aggressive driving (e.g., speeding) across larger samples.</div></div>","PeriodicalId":48355,"journal":{"name":"Transportation Research Part F-Traffic Psychology and Behaviour","volume":"123 ","pages":"Article 103835"},"PeriodicalIF":5.0,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149160619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, two critical gaps persist. First, how the determinants of intention differ between expectation-based beliefs and experience-calibrated appraisals after real-world physical exposure remains largely untested. Second, evidence from developing-country contexts, where mixed traffic, socio-economic constraints, and first- and last-mile needs differ markedly, is scarce. This study addresses both gaps by tracking intention in a real-world pilot using a panel two-wave survey embedded in a developing-country setting. Separate structural equation models were estimated for the pre- and post-riding experience phases and then compared, complemented by multigroup analysis across age, gender, income, bus-use frequency, and distance to bus stops. The study extends theory on AS adoption by showing that the determinants associated with use intention differ between the pre- and post-riding phases. Using pre- and post-exposure data from an Indonesian campus pilot, we interpret these phase-specific, segment-contingent patterns as cognitive reconfiguration. Environmental awareness and familiarity of use were associated with intention only before riding, whereas perceived risk and trust and social influence were associated with intention only after riding; hedonic motivation was significant in both phases but only in some segments after riding. The findings suggest that experience may act as a structural filter on acceptance rather than merely a moderator, a proposition that warrants confirmation in longitudinal designs. Practically, policymakers and operators should deploy segment-specific communication tailored to safety-sensitive, enjoyment-driven, value-oriented, and novelty-seeking users.</div></div>","PeriodicalId":48355,"journal":{"name":"Transportation Research Part F-Traffic Psychology and Behaviour","volume":"123 ","pages":"Article 103838"},"PeriodicalIF":5.0,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149160620","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}

Future brain–computer interfaces (BCIs) for driver monitoring and workload-adaptive automation promise direct access to neurophysiological signals, potentially offering higher sensitivity than conventional systems. Despite this potential, drivers' acceptance of BCIs in real-world driving remains largely unexplored. Because driving constitutes a complex sociotechnical system context, user, task, and system characteristics are likely to shape acceptance. This study thus examines the acceptance of non-invasive, wearable BCIs for workload-adaptive driver assistance from a sociotechnical perspective. We conducted an online experimental vignette study using a between-participant design (<em>N</em> = 1201). Participants evaluated one of twelve animated driving scenarios in which a BCI detected high workload and initiated assistance. The scenarios varied three sociotechnical characteristics: driver status (able-bodied vs. disabled), the function within the assisted driving task (primary, secondary, or tertiary), and type of automation (adaptive vs. hybrid). Respondents evaluated acceptance using an adapted Unified Theory of Acceptance and Use of Technology (UTAUT2) framework. Acceptance of BCI-based adaptive automation varied systematically across conditions. Findings show that scenario evaluations indicated higher acceptance when BCIs supported driving-related functions and when the scenario depicted a driver with a disability. No differences were observed between the two activation modes tested. By integrating sociotechnical characteristics into an established acceptance framework, this study advances understanding of BCI acceptance in driving and informs the user-centered design of neuroadaptive driver assistance systems.</div></div>","PeriodicalId":48355,"journal":{"name":"Transportation Research Part F-Traffic Psychology and Behaviour","volume":"123 ","pages":"Article 103828"},"PeriodicalIF":5.0,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149160617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using an augmented reality HMI in a driving simulator, we examined how different levels of V2V cooperative process transparency affect driver cognition during cooperative lane changes. Three interface conditions were compared: a baseline condition with no V2V cooperation information, a limited-transparency condition presenting only the final cooperation outcome, and a high-transparency condition presenting the full cooperation process. Twenty-five participants completed the experiment, and subjective, performance, and qualitative data were collected. The results showed that V2V cooperative process transparency significantly affected drivers’ subjective responses. Compared with the baseline condition, both the limited- and high-transparency conditions significantly improved overall situation awareness and reduced workload. The limited-transparency condition also significantly increased trust and system usability, whereas the differences in trust and system usability between the high-transparency and baseline conditions were not significant. Compared with the limited-transparency condition, the high-transparency condition significantly improved overall situation awareness, whereas overall workload, trust, and system usability did not differ significantly; at the workload-dimension level, however, Temporal Demand was significantly lower under high transparency. No significant differences were found in task performance across conditions. Qualitative interviews indicated that most participants considered the richer interface understandable and acceptable, although some reported possible information overload.

Adopting a layered behavioural perspective, this study examines how reasoned and unreasoned influences operate across multiple layers of mobility decision-making to shape MaaS adoption intentions in Kochi, India. Drawing on 49 semi-structured interviews, the analysis reveals that adoption is not a discrete technological choice but a layered and conditional process. Structural and spatial conditions determine feasibility, while social roles and household responsibilities mediate practical acceptability. At the cognitive level, instrumental evaluations of cost, time, and flexibility interact with habitual reliance on private modes, emotional comfort, and perceived control. These interacting filters produce conditional, rather than sustained, behavioural commitment to MaaS. The study contributes a behaviourally grounded analytical framework that reframes MaaS adoption as a socio-behavioural transition rather than a purely technological shift. The findings underscore the need for infrastructure-first readiness, regulatory alignment, and trust-building strategies to translate intention into sustained mobility change.</div></div>","PeriodicalId":48355,"journal":{"name":"Transportation Research Part F-Traffic Psychology and Behaviour","volume":"123 ","pages":"Article 103837"},"PeriodicalIF":5.0,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149211999","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}
