A Background Information Form, a Safe Driving Self-Regulation Questionnaire (SD-SRQ), the Traffic Climate Scale (TCS), and the Multidimensional Driving Style Inventory (MDSI) were used as instruments; data was collected from 471 Israeli and 400 Turkish participants. The contribution of the interaction between the motivation for safe driving and the traffic culture/climate in Israel and Türkiye on driving styles was examined by a moderated moderation analysis. The analysis showed that the two countries are differently impacted by traffic climate and safe driving motivation. The study’s key finding is that while emotionally demanding traffic and autonomous forms of motivation and amotivation have an impact on the patient-careful driving style in Türkiye, traffic climate which is emotionally demanding and requires abilities and skills, together with controlled forms of motivation and amotivation have an impact on dissociative and anxious driving styles in Israel.

Despite the availability of connected information, drivers might still face decision-making dilemmas that pose potential risks to traffic safety. To explore the impact of connected information in such interactive dilemmas on driving decisions and traffic operation, a video-based preemptive/yielding (P/Y) decision-making experiment involving 62 straight-going (SG) and 62 left-turning (LT) drivers was conducted under connected information provision. Recognizing the potential adverse effects on operational efficiency if both drivers choose to yield and the threat to traffic safety in scenarios where both opt for preemptive actions, the joint decisions made by SG and LT drivers were treated as response outcomes. Three interactive dilemmas conditions, the provision of turning information, and individual characteristics attributes were considered as explanatory variables. By developing a random regret minimization mixed multinomial logit model, this study examined the effects of connected information on joint decisions and their subsequent influence on potential traffic safety and operational efficiency. The findings indicate that (1) different dilemma conditions significantly influence joint decisions. The high probability of Y-Y and P-P joint decisions suggests that even with the availability of connected information, better driving decisions may not always be achieved. Notably, providing connected information in dilemma condition (2) (where the SG vehicle had a smaller speed but a closer distance to the intersection than the LT vehicle) increases the likelihood of heterogeneous Y-P joint decisions, thus benefiting overall traffic operations. (2) Turning information generally contributes to traffic operations by increasing Y-P joint decisions, yet it also exacerbates potentially hazardous interactions, marked by an increase in both sides choosing preemptive behaviors (P-P joint decisions). This emphasizes the need for traffic authorities to regulate left-turning vehicles’ turn signal usage. (3) Heterogeneous individual characteristics tend to lead to diverse joint decisions, particularly concerning penalty record, accident history, and driving skill. Surprisingly, the heterogeneity of education, income, and driving experience presents a higher probability of homogeneous joint decisions. Overall, this study contributes significantly to understanding the determinants influencing interactive driving decision-making under connected information provision, aiming to the advancement of more efficient and safer vehicle-connected transportation systems.</div></div>","PeriodicalId":48355,"journal":{"name":"Transportation Research Part F-Traffic Psychology and Behaviour","volume":"109 ","pages":"Pages 320-335"},"PeriodicalIF":3.5,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143099904","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}

The regulations on distracted driving mainly restrict physical and visual distractions related to the use of handheld phones, with less restrictions on cognitive distractions. However, it is not yet clear which cognitive distracted driving behaviors may lead to significant decrease in driver vigilance. The purpose of this study is to assess how different cognitive distractions affect driver vigilance when drivers use advanced driving assistance functions in a monotonous driving highway environment. Using a driving simulator and external devices, the multi-dimensional including mental workload, vigilance reaction time and accuracy, eye movement data were collected from 31 participants. Cognitive distractions types included visual-manual-cognitive distraction tasks, auditory-cognitive distraction tasks and a no-distraction task. Three Multiple Criteria Decision-Making methods were used to evaluate the driver vigilance level during different types of cognitive distractions. The results indicate that participants exhibited lower vigilance levels during visual-manual-cognitive distraction tasks (L3 and L2) compared to auditory-cognitive distraction tasks (L2 and L1) and the no-distraction task (L1). This was due to the nature of the visual-manual-cognitive tasks, such as the message-sending task, which involve both language generation and comprehension, requiring higher levels of brain activation and attention resources. Therefore, visual-manual-cognitive distraction tasks should be limited when drivers use advanced driving assistance functions. In contrast, simple auditory-cognitive distractions, such as listening to new tasks, helped drivers remain alert and maintained vigilance levels comparable to the no-distraction task. This indicates that the auditory-cognitive distractions that involve language comprehension can assist drivers in maintaining an appropriate stimulation level, thereby preventing a decrease in vigilance associated with mind-wandering. Therefore, auditory-cognitive distractions involving language comprehension can be permitted in simple driving environments. As the vigilance level was lower at moderate level for auditory-cognitive involving working memory(1-back), it is recommended to warn this type of distraction.</div></div>","PeriodicalId":48355,"journal":{"name":"Transportation Research Part F-Traffic Psychology and Behaviour","volume":"109 ","pages":"Pages 571-587"},"PeriodicalIF":3.5,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143099978","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}

Increasing attention has been directed toward the subjective dimensions of walkability, such as individuals’ emotional responses to specific environments, due to their significant association with walking intentions. However, assessing subjective feelings through surveys is challenging to apply consistently across numerous alleyways. Therefore, this study investigates the potential of smart wearable sensors to assess pedestrians’ emotional experiences during walking. Specifically, the research focuses on classifying emotional states, which are categorized as pleasant or unpleasant (i.e., valence)–within pedestrian environments. This classification is achieved by integrating multi-sensor data and anomaly detection techniques. Participants’ physiological and movement data, including electrodermal activity, heart rate variability, and acceleration, were collected via wearable devices while simultaneously surveying their emotions for data labeling. Machine learning algorithms were used to classify emotions by integrating features derived from sensor data and anomaly detection outcomes. The results demonstrate that integrating data from multiple sensors significantly improved the accuracy of emotion classification compared to relying on single-sensor data alone. The performance was further enhanced by incorporating anomaly features into the analysis. These findings advance the understanding of pedestrians’ subjective emotional experiences and their momentary feelings within pedestrian environments through the continuous application of wearable sensors.

To rectify this limitation, an on-road “think aloud” study was conducted with participants in the UK and supplemented by a video-cued retrospective interview using a shortened version of the Schema World Action Research Method. 175 decision points were then analysed using Neisser’s Perceptual Cycle Model, which highlights the relationships between the information perceived from the narrow passage environment, a driver’s schema, and the actions taken. It was found that drivers conduct four key assessments, including evaluating their interaction partner’s intention and the suitability of give way gaps on both sides of the road, when deciding what actions to take during a narrow passage interaction. These results provide a clearer understanding of how driver behaviour is influenced by different contextual/situational factors in a safety critical driving situation and helps ensure that future mathematical models better reflect driver decision-making during narrow passage interactions.

Sleep deprivation tends to impair cognitive function, which compromises drivers’ capabilities and increases the likelihood of crashes. Researchers have developed driver monitoring systems that can detect driving impairment by utilising driving performance measures and drivers’ physiological measures. However, sleep deprivation could induce specific physiological variations accompanied by changes in driving performance, thereby rendering detection of driving impairment challenging. This study aims to categorise drivers’ physiological and driving performance indicators associated with sleep deprivation and to evaluate existing evidence using a systematic review. Additionally, by examining the combined measures of behavioural and physiological state of vigilance, this review identifies correlations between various driving performance metrics and drivers’ physiological responses that can help in detecting the state transitions of drivers. The twenty-five studies that met the review criteria were chosen in accordance with the PRISMA framework from four research databases: Scopus, Web of Science, Transportation Research International Documentation (TRID), and IEEE Xplore digital library. Findings from this systematic review provide consistent evidence that sleep deprived driving induces physiological variations and leads to driving performance deficits. Sleep deprived driving resulted in increased electroencephalographic slow activity (alpha and theta power) of the brain and correlated with driving performance deficits. Ocular markers, including saccadic velocity, mean blink duration, variations in gaze behaviour, and PERCLOS, were able to detect physiological impairments while driving in sleep-deprived conditions. Combining physiological measures, such as slow eye movements and increased power in the alpha and theta bands of the EEG, also served as a robust measure of impaired driving performance. Notably, this review acknowledges limitations due to the diversity of methodologies across the studies, which complicates direct comparisons of findings. Nonetheless, these research findings will give directions for future research in developing strategies for robust real-time warning systems incorporating hybrid measures to mitigate the consequences of sleep deprived driving.</div></div>","PeriodicalId":48355,"journal":{"name":"Transportation Research Part F-Traffic Psychology and Behaviour","volume":"109 ","pages":"Pages 458-479"},"PeriodicalIF":3.5,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143099887","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}
