Insight in the acceptability of Intelligent Speed Adaptation (ISA) is an important requirement for the supported implementation of speed limiter technology. The aim of this study was to investigate the behavioural intention to accept ISA technology in a sample of 218 male minibus taxi drivers in Addis Ababa, Ethiopia. The hypothesized framework proposed attitude, effort expectancy, performance expectancy and social influence as determinants of the behavioural intention to accept ISA technology. It was found that positive evaluation towards using ISA technology and the degree of convenience associated with the use of this technology are likely to represent target goals for interventions aimed to promote the use of such technology among minibus taxi drivers. These results have also practical implications for the Ethiopian Transport Authority which is taking the initiative to large scale deployment of in-vehicle speed control technology in Ethiopia.

Hanoi City is a typical motorcycle dominant city in Vietnam with a modal share of motorcycles of more than 80% and motorcycle riders involved in more than 70% of road fatalities. It is important to understand the major causes of motorcycle crash severity to suggest effective countermeasures. There have been studies elsewhere examining factors related to small-displacement motorcycle crash severity, but work in Vietnam is scarce. This study uses ordinal logistic regression to investigate contributory factors to the odds of severe crashes involving motorcycle riders. A distinction is made between crashes where motorcyclists are involved as the second party (i.e., as victims of the crash) on the one hand and as the first party (i.e., as the person responsible for causing the crash) on the other hand. Results show that age and gender of the first party person, size of the vehicle collided with, and presence of a pillion passenger significantly contribute to the severity of crashes in which motorcyclists are involved as the second party. Significant factors to the severity of crashes in which motorcyclists are involved as the first party are age, time of the crash, road class, size of the second party vehicle, pillion passenger presence, and riding speed. The findings contribute to a deeper understanding of fatal crashes with small-displacement motorcycles in a developing city. This study helps to identify countermeasures to improve road safety of small-displacement motorcycle riders.

People with an autism spectrum disorder (ASD) might experience difficulties while driving, for instance, related to hazard perception. These difficulties may be related to cognitive issues (internal) such as attention-shifting, sequential performance, and multitasking. Possibly related to these issues, some people with ASD experience stress and anxiety while driving. Among other reasons, stress could relate to the roadway environment and infrastructure design, e.g., sensory overload due to lighting conditions. Yet, the relationship between roadway environment and infrastructure and driving experiences of people with ASD is somewhat overlooked in previous research. This study aimed to (1) explore how people with ASD experience roadway environment/infrastructure while driving (2) identify coping strategies to deal with interfering elements related to roadway environment/infrastructure. There were twelve participants (mean age: 34.8, of which 66.7% were female), semi-structured interviews to examine the appraisal of roadway environment and infrastructure. The interviews were analyzed based on a phenomenological hermeneutical approach. Each participant reported both positive (e.g., environment and infrastructure can be supporting, enhance predictability) and negative appraisals (e.g., stress, anxiety) to roadway environment/infrastructure. Various elements such as light, noise, and, being rushed caused additional pressure on (1) the driving performance (e.g., driving too slowly, not noticing important elements), (2) traffic analyzing skills (e.g., difficulties in overseeing new situations), (3) and the efficient application of traffic rules. The participants described different coping mechanisms to deal with the influence of interfering elements; for example, alternative transport means or adjusting behavior (e.g., switch off radio, early departure). This demonstrates that besides internal factors such as attention, external factors like roadway environment and infrastructure can also influence the driving experience of ASD drivers, potentially leading to driving-related stress and anxiety. Policymakers could consider the current findings when designing new guidelines and roadway environment and infrastructure design principles.

Driving anger and aggressive driving are main contributors to crashes, especially among young males. Trait driving anger is context-specific and unique from other forms of anger. It is necessary to understand the mechanisms of trait driving anger to develop targeted interventions. Although literature conceptually distinguished reactive and proactive aggression, this distinction is uncommon in driving research. Similar, cognitive biases related to driving anger, measured by a combination of explicit and implicit measures, received little attention. This pilot study related explicit and implicit measures associated with reactive and proactive aggression to trait driving anger, while considering age. The sample consisted of 42 male drivers. The implicit measures included a self-aggression association (i.e., Single-Target Implicit Association Test) and an attentional aggression bias (i.e., Emotional Stroop Task). Reactive aggression related positively with trait driving anger. Moreover, a self-aggression association negatively related to trait driving anger. Finally, an interaction effect for age suggested that only in young male drivers, higher proactive aggression related to lower trait driving anger. These preliminary results motivate further attention to the combination of explicit and implicit measures related to reactive and proactive aggression in trait driving anger research.

Mobile phone use while riding is one of the five most common risky behaviors of motorcycle riders in Vietnam. This study investigated motorcyclist’s mobile phone use while riding intention and behavior based on the extended Theory of Planned Behavior (TPB) framework. Based on this framework, attitude, subjective norm, perceived behavioral control, habits, and health motivation underlying the rider’s mobile phone use while riding intentions and behavior were included in a questionnaire and captured by direct and indirect measurements. Small-displacement motorcycle riders (N = 291) completed the extended TPB based questionnaire. An exploratory factor analysis technique identified the selected factors (e.g., attitude, habit, etc.). Moreover, Structural Equation Modeling results showed moderate to good fits to the observed data. Therefore, the results supported the utilization of extended TPB framework in identifying factors of mobile phone use while riding intention and behavior. Specifically, negative attitude, perceived behavioral control, and mobile phone use while riding habit related to the intention to use a mobile phone while riding of small-displacement motorcyclists. Meanwhile, habit and behavioral intention related to the behavior to use a mobile phone while riding of small-displacement motorcycle riders. Especially, the correlation between behavioral intention and self-reported behavior was very strong. This finding embraced previous research indicating that intention was a major motivational component of behavior. Based on the results, safety intervention implications for small-displacement motorcycle riders were discussed.

Introduction: Heterogeneous driving populations with many different origins are likely to have various sub-cultures that comprise of drivers with shared driver characteristics, most likely with dissimilar traffic safety cultures. An innovative methodology in traffic safety research is introduced which is beneficial for large datasets with multiple variables, making it useful for the multi-variate classification of drivers, driving attitudes and/or (risky) driving behaviours. Method: With the application of multidimensional scaling analysis (MDS), this study explores traffic safety culture in the State of Qatar using a questionnaire and investigates the similarity patterns between the questionnaire items, aiming to classify attitudes towards risky driving behaviours into themes. MDS is subsequently applied to classify drivers within a heterogeneous driving sample into sub-cultures with shared driver characteristics and different risky driving attitudes. Results: Results show that acceptance of speeding is highest among the young Arabic students and acceptance of distraction and drivers’ negligence such as phone use and not wearing a seatbelt is highest among male Arab drivers. Acceptance of extreme risk-taking like intoxicated driving and red-light running is highest among South-Asian business drivers. Conclusion: It is important and practical to understand risky behavioural habits among sub-cultures and thereby focussing on groups of drivers instead of individuals, because groups are easier to approach and drivers within sub-cultures are found to influence each other. By indicating which groups of drivers are most likely to perform specific risky driving themes, it is possible to target these groups and effectively emphasise certain subsets of risky driving behaviours during training or traffic safety education. Practical Applications: This study provides guidance for the improvement of driver education and targeted traffic safety awareness campaigns, intending to make changes to attitudes and habits within specific driver sub-cultures with the aim to improve traffic safety on the longer term.

Driving is a complex, goal-directed task. ASD can be related to impairments in executive functioning (EF), which may interfere with driving. This study aimed to investigate (1) if 16 young novice drivers with ASD exhibited a divergent performance on EF tests compared to 18 neurotypical peers, (2) if ASD participants exhibited a divergent driving performance compared to their neurotypical peers, and (3) if differences in driving performance would be related by the performance on the EF tasks. All participants completed a driving simulator scenario and computer-task battery. Driving error classification allowed the selection of several driving measures (e.g., collisions, speeding). Three EF tasks measuring working memory (WM), attention, and response inhibition were included. Results indicated lower WM and attention performance of the ASD participants compared to the control group, whereas response inhibition was similar across groups. Furthermore, the current study demonstrated that people with ASD can be considered as capable drivers once they have learned how to drive, that it is important to take different types of hazards into account, and that EF performance is related to driving performance. This relation may be different for drivers with and without ASD. Moreover, the relation may depend on the specific EFs and driving parameters under investigation. Future research could focus on the very early phases of driving education, and include additional driving and EF measures.

Cardiovascular disease (CVD) patients benefit from an active lifestyle with a certain level of physical activity. Assessing the physical activity level of patients in an objective manner can be problematic. Self-reporting tends to be biased and lack of therapy adherence has a negative influence on managing disease risk factors. In this paper we propose a digital framework which collects the level of physical activity of CVD patients with an app and processes this data to obtain an objective measure of physical activity, which is visualized in a dashboard available for the caretakers. By exploiting behavioural theories and combining them with this objective measure of physical activity, patients are classified according to their attitude towards active travel behaviour. Based on this knowledge, caretakers can propose a more active lifestyle to patients by identifying opportunities in making the daily trips of the patients more active. For example, short distances done by car can be suggested to be replaced by walking or biking. The behaviour theories also allow to assess the risk of not adhering to the prescribed therapy. This tool will help in providing a more tailored care and approach to persons with CVD.

Intersection accidents result in a significant proportion of road fatalities, and attention allocation likely plays a role. Attention allocation may depend on (limited) working memory (WM) capacity. Driving is often combined with tasks increasing WM load, consequently impairing attention orienting. This study (n = 22) investigated WM load effects on event-related potentials (ERPs) related to attention orienting. A simulated driving environment allowed continuous lane-keeping measurement. Participants were asked to orient attention covertly towards the side indicated by an arrow, and to respond only to moving cars appearing on the attended side by pressing a button. WM load was manipulated using a concurrent memory task. ERPs showed typical attentional modulation (cue: contralateral negativity, LDAP; car: N1, P1, SN and P3) under low and high load conditions. With increased WM load, lane-keeping performance improved, while dual task performance degraded (memory task: increased error rate; orienting task: increased false alarms, smaller P3). Practitioner Summary: Intersection driver-support systems aim to improve traffic safety and flow. However, in-vehicle systems induce WM load, increasing the tendency to yield. Traffic flow reduces if drivers stop at inappropriate times, reducing the effectiveness of systems. Consequently, driver-support systems could include WM load measurement during driving in the development phase.

Prior studies indicated higher collision rates among young novice drivers with peer passengers. This driving simulator study provided a test for a dual process theory of risky driving by examining social rewards (peer passengers) and cognitive control (inhibitory control). The analyses included age (17–18 yrs, n = 30; 21–24 yrs, n = 20). Risky, distracting, and protective effects were classified by underlying driver error mechanisms. In the first drive, participants drove alone. In the second, participants drove with a peer passenger. Red-light running (violation) was more prevalent in the presence of peer passengers, which provided initial support for a dual process theory of risk driving. In a subgroup with low inhibitory control, speeding (violation) was more prevalent in the presence of peer passengers. Reduced lane-keeping variability reflected distracting effects. Nevertheless, possible protective effects for amber-light running and hazard handling (cognition and decision-making) were found in the drive with peer passengers. Avenues for further research and possible implications for targets of future driver training programs are discussed.

Youth with an autism spectrum disorder (ASD) depend to a great extent on friends and family for their transportation needs. Although little research exists, Cox et al. (2012) surveyed parents/caregivers of youth with ASD (previously) attempting to learn to drive. This study serves as an extension by surveying driver instructors. Several questions queried advice for teaching youth with ASD how to drive, and for improving the current driving education to better fit the needs of youth with ASD. Furthermore, respondents were asked to indicate whether specific characteristics, often associated with ASD, have an impact on driving ability. A total of 52 driver instructors reported potential problems when teaching youth with ASD to drive. Advice for teaching youth with ASD to drive mainly focused on a need for structure, clarity, visual demonstration, practice, repetition and an individualized approach. Results however also showed that the relation between ASD and driving performance might not always be negative but can be positive. Practical implications are provided.

Distracted driving has received increasing attention in the literature due to potential adverse safety outcomes. An often posed solution to alleviate distraction while driving is hands-free technology. Interference by distraction can occur however at the sensory input (e.g., visual) level, but also at the cognitive level where hands-free technology induces working memory (WM) load. Active maintenance of goal-directed behavior in the presence of distraction depends on WM capacity (i.e., Lavie's Load theory) which implies that people with higher WM capacity are less susceptible to distractor interference. This study investigated the interaction between verbal WM load and WM capacity on driving performance to determine whether individuals with higher WM capacity were less affected by verbal WM load, leading to a smaller deterioration of driving performance. Driving performance of 46 young novice drivers (17-25 years-old) was measured with the lane change task (LCT). Participants drove without and with verbal WM load of increasing complexity (auditory-verbal response N-back task). Both visuospatial and verbal WM capacity were investigated. Dependent measures were mean deviation in the lane change path (MDEV), lane change initiation (LCI) and percentage of correct lane changes (PCL). Driving experience was included as a covariate. Performance on each dependent measure deteriorated with increasing verbal WM load. Meanwhile, higher WM capacity related to better LCT performance. Finally, for LCI and PCL, participants with higher verbal WM capacity were influenced less by verbal WM load. These findings entail that completely eliminating distraction is necessary to minimize crash risks among young novice drivers

This study investigated if decreased cognitive control, reflected in response inhibition and working-memory performance, is an underlying mechanism of risky driving in young novice drivers. Thirty-eight participants aged 17 to 25 years old, with less than 1 year of driving experience, completed a simulated drive that included several risky driving measures. Measures of response inhibition and verbal working memory were negatively associated with the standard deviation of the lateral lane position. Response inhibition, but not working memory, was also negatively related with the detection of, reaction to, and crashes with road hazards. Unexpectedly, increased cognitive control did not always relate to decreased risky driving. Visuospatial working-memory performance related positively with yellow-light running and negatively with the minimal following distance inside the city center. The findings evidence the role of cognitive control in explaining risky driving in young novice drivers. This relationship, however, differed per cognitive function and per driving parameter. Implications for future research and traffic safety interventions are discussed.
