It’s all in the mind: The relationship between mindfulness and nomophobia on technology engagement while driving and aberrant driving behaviours

This study investigated the relationship between mindfulness and nomophobia on technology engagement while driving and aberrant driving behaviours. Nine hundred and ninety participants completed an online survey (Female: 68.6%; Age: M = 51.2 years, SD = 15.7, Range = 18.0–84.0 years) that assessed mindfulness, nomophobia, technology engagement while driving, aberrant driving behaviour, and self-reported crashes and infringements during the past two years. Structural equation modelling (SEM) was used to examine the relationships between mindfulness and nomophobia, on one hand, with self-reported engagement with technology while driving and general aberrant driving behaviours (combination of errors, lapses and violations) on the other. The results of the SEM showed that, as expected, mindfulness shared negative relationships with nomophobia, engagement with technology and aberrant driving behaviours, while all other relationships were positive. In terms of engagement with technology, there were direct and indirect paths between nomophobia and mindfulness and engagement with technology. The results of this study demonstrate the positive influence mindfulness can have on nomophobia, engagement with technology while driving, and dangerous driving behaviours that have been associated with crash risk. Mindfulness practices may reduce the effect of nomophobia on engagement with technology while driving and increased dangerous behaviours as a result. This will be increasingly important as modern work and social practices encourage people to increasingly use the phone while driving, and the technology within smart devices, and connectivity of these to the vehicle, increase. More research is needed to understand whether mindfulness-based interventions can reduce nomophobia, and thereby improve driving behaviours and reduce crash rates.     

The prevalence of in-vehicle driving distractions in road traffic collisions as a function of road type

While some previous research suggests that conversing with passengers is the most prevalent in-vehicle distraction while driving, others have concluded instead that it is mobile phone use. One possible explanation for these differences is that distraction prevalence varies with road type. To test this proposal the current study investigated the prevalence of in-vehicle driving distraction in road traffic collisions (RTCs) as recorded in national records from the US and New Zealand. Analysis using odds ratios suggested conversing with passengers to be a more prevalent distraction in RTCs on minor roads than on major roads, and mobile phone use to be a more prevalent distraction on major roads than on minor roads. These results show the importance of considering the type of road when investigating the prevalence of driving distractions in RTCs in future research.     

How does emotional intelligence predict driving behaviors among non-commercial drivers?

Dangerous driving behaviors have been found to be a leading contributor to vehicle crashes and fatalities, with more than 2.7 million people injured and 36,560 people killed in the United States in 2018 (NHTSA, 2020). Drivers’ emotions have been found to be among the leading contributors to dangerous driving behaviors. Emotions can be measured and understood through one’s emotional intelligence (EI). Previous research has confirmed the relationship between EI and dangerous driving behaviors among general driving populations in limited scope. This study analyzed dangerous driving behaviors (e.g., aggressive driving) among non-commercial US drivers. 615 US drivers ages 18 to 65 (M = 31.14, SD = 11.15) with valid US driver’s licenses (non-commercial) participated in this study. Participants completed an online survey through Qualtrics that included the Trait Emotional Intelligence Questionnaire (TEIQue-SF) to measure different dimensions of EI and the Dula Dangerous Driving Index (DDDI) and the Driving Behavior Questionnaire (DBQ) to measure dangerous driving behaviors. Furthermore, participants reported their demographic information, including age, sex, and location. Correlation analysis revealed that significant associations exist between dangerous driving behaviors and EI. The emotionality component of EI was found to be the strongest predictor of dangerous driving behaviors. The findings concluded that participants with higher EI scores engaged in less dangerous driving behavior, resulting in fewer crashes and fatalities. Thus, promoting and improving EI may be useful in preventing risky driving among non-commercial drivers. Incorporating emotional intelligence education in driver’s education, workplace training, and licensing procedures can be helpful to develop safer drivers. Further research is needed to investigate commercial drivers’ behaviors in relation to EI.     

The influence of fatalistic beliefs and risk perceptions on road safety attitudes in Latin America; A two-country study

Road safety is a major challenge in the Latin American region; however, there is a significant lack of research undertaken there. To contribute to addressing this gap, this paper reports on an exploration of the antecedents of traffic safety attitudes in two Latin American contexts: Brazil and Ecuador. Building on related work undertaken in other countries, the research explored the relationships between fatalistic beliefs, traffic risk perceptions, and road safety attitudes, while accounting for age, gender, and exposure to the road environment. Data from 2432 individuals, analysed using Structural Equation Modelling, revealed differences in the extent to which different fatalistic belief constructs (including divine control, luck, helplessness, internality, and general fatalism) were related to road safety attitudes. Moreover, fatalistic beliefs were found to influence road safety attitudes both directly and indirectly through their influence on risk perceptions. Those that reported more fatalistic beliefs also reported more dangerous attitudes to road safety and a lower perception of on-road risk. Mirroring findings from work undertaken in other countries, we found males compared to females and younger compared to older respondents to report more dangerous attitudes to road safety, with inconclusive results for risk perceptions. We also found very similar patterns of results in the data from the two countries included in the research. Results are discussed with regards to informing the design of road safety interventions aimed at influencing individual road user attitudes and, ultimately, human behaviour and system performance.     

What is the motor vehicle crash risk for drivers with a sleep disorder?

In many parts of the world, drivers with serious sleep disorders have restrictions on their licence – with the fitness-to-drive criteria varying across licensing jurisdictions. This study aimed to systematically review the literature that evaluated the available scientific evidence for the relationship between sleep disorders and two driving safety outcome measures: (i) motor vehicle crashes (MVC) and (ii) on-road driving test outcome. This review was registered with PROSPERO in July 2019 (see CRD42019144643). A systematic search of public health, psychology and transport databases was conducted on November 8th, 2019. The quality of evidence for each study was rated using the National Heart, Lung and Blood Institute Quality Assessment tools. Thirty-nine studies published between 1976 and 2015 met the inclusion criteria (n = 9 case-control; n = 24 cohort/cross-sectional; n = 6 before-after). Overall, the quality of evidence for 22 studies was rated as ‘good’, nine as ‘fair’ and eight as ‘poor’. Included studies addressed: sleep apnoea and sleep-related breathing disorders (n = 35); central disorders of hypersomnolence and narcolepsy (n = 5), and insomnia (n = 2), with some studies covering multiple sleep disorders. Of the thirty-five studies specifically investigating MVC risk associated with sleep apnoea, eighteen studies reported an increased risk (n = 11 ‘good’, n = 4 ‘fair’, n = 3 ‘poor’ quality), seven reported no difference in risk (n = 3 ‘good’, n = 4 ‘fair’ quality), and two provided inconclusive findings (n = 1 ‘good’, n = 1 ‘fair’ quality). Most studies suggested that increased sleep apnoea severity was associated with an increased MVC risk. Furthermore, untreated sleep apnoea was predominantly associated with increased risk, whilst decreased risk was associated with Continuous Positive Airway Pressure (CPAP) and uvulopalatopharyngoplasty (UPPP) treatments. Five studies (n = 3 ‘good’, n = 2 ‘fair’ quality) investigated MVC risk associated with disorders of hypersomnolence and narcolepsy, and all reported increased risk. Only two studies investigated MVC risk associated with insomnia, with inconsistent findings: one reporting increased MVC risk (‘good’) and one reporting no difference (‘fair’). Regarding impacts on on-road driving test outcome, our comprehensive search found no studies investigating the association between sleep disorders and this driving safety outcome measure. Notwithstanding the limitations of the included studies, the weight of evidence suggests a moderately elevated MVC risk for drivers with sleep disorders (sleep apnoea; hypersomnia and narcolepsy), with the majority reporting around two and a half times higher risk, and lower risk with treatment. This evidence is consistent with current fitness-to-drive guidelines, most of which specify licence restrictions conditional upon severity, treatment compliance and effective response to treatment. The generalisability of the findings is limited as many identified studies had methodological limitations, were conducted across a wide time period, in numerous licensing jurisdictions with different requirements, and across a diverse range of participant populations. A large-scale, population-based controlled study, in multiple licensing jurisdictions with equivalent licensing and fitness-to-drive requirements, is warranted to rigorously investigate MVC risk and sleep disorders, including evaluating the possible benefit of therapies.     

Mobile phone use while driving in Finland

Mobile phones represent one of the most common distractions for drivers and phone use while driving is particularly problematic in Finland. The aim of this research was to explore the Finnish sample of responses from ESRA2 (E-Survey of Road users' Attitudes) with a specific focus on the distracting behaviours related to mobile phone usage while driving. ESRA2 data is derived from online surveys amongst a representative sample of the adult populations in each participating country. In total a sample of 994 responses were collected in Finland for ESRA2, which included 703 responses from participants who held a driver’s licence and reported driving a car in the 30 days prior to the survey.The results provide evidence of the problematic usage of mobile phones while driving in Finland. Mobile phone use was considered across three specific types of usage: (1) handheld phone calls while driving; (2) handsfree phone calls while driving; (3) texting, emailing or social media use while driving. Almost half (49.4 %) of the sample reported using a handheld mobile phone to make a call while driving at least once in the 30 days prior to the survey. A similar percentage (41.4 %) of the sample had used a phone hands-free and 35.6 % had texted, emailed, or used social media.The study highlights how mobile phone usage is a complex and multifaceted issue and that there are a broad range of underlying factors that influence mobile phone usage depending on the way in which people engage with their mobile phone while driving. The findings suggest that a systematic approach to reducing mobile phone distraction is needed that addresses the issue through a combination of legislation, enforcement, and education.     

Safer road users: Investigating the influence of PRIME road markings on motorcycle rider behaviour

Innovative road markings for motorcyclists, designed as Perceptual Rider Information for Maximising Expertise and Enjoyment (PRIMEs) were installed on the approach to demanding left-hand bends at six trial sites and a comparison site across the West Highlands of Scotland. These road markings were presented as a series of ‘gateways’ to encourage safer riding. Video data were collected to measure motorcycle speed, lateral position, braking and use of the road markings, before and after the PRIMEs were installed. A total of 9,594 motorcyclists were observed. Across the six trial sites, statistically significant reductions in speed were observed (at three sites). Significant changes in lateral position were observed at the final PRIME gateway marking (at one site), and at the apex of the bend (at three sites). Reduced braking was observed at three sites and there was a statistically significant increase in the use of PRIME road markings across four of the sites. No statistically significant effects were observed at the comparison site. These findings are discussed in relation to sustained effects and aspects of the ‘Safe System’ approach that are relevant to reducing motorcycle casualties.     

Synchronising self-displacement with a cross-traffic gap: How does the size of traffic vehicles impact continuous speed regulations?

In this article, we investigated what visual information is used by drivers at a road crossing when they want to synchronize their displacement with that of an incoming traffic train. We made the hypothesis that synchronizing self-displacement with that of a traffic gap shares the same perceptual-motor basis as interception tasks. While a large body of literature demonstrates that bearing angle is used to control interception, another range of studies points to optical size and expansion as playing a critical role in collision avoidance. In order to test the hypothesis of the exclusive use of bearing angle in road crossing task, we manipulated the optical size and expansion of oncoming traffic elements independently of bearing angle variations. We designed a driving simulator study in which participants were to adjust their approach speed in order to cross a road junction within a moving traffic gap. We manipulated the initial offset of participants with the traffic gap, the geometry of the road junction and the way optical size of oncoming traffic elements evolves over the course of a trial. Our results showed an effect of optical size and optical expansion manipulations eventhough, we also found similar displacement profiles as in interception studies. This demonstrates that bearing angle could not explain alone the control of such a complex perceptual-motor task. We discuss these results with regard to similar results in other fields of literature.     

Visual exploration of pedestrian crossings by adults and children: Comparison of strategies

In pedestrian crossing situations, children are less able to make safe crossing decisions compared to adults.The aim of the present study was to analyze and compare the ocular behaviour of children and adults in the pedestrian crossing situations using the eye tracking. The study involved 22 children ranging in age from 5 years to 6 years 2 months and 22 adults. Children and adults participated in a brief eye tracking session designed to explore field of view in road crossing scenarios. They were presented with four pictures of pedestrian crossing and instructed to observe the pictures as if they were on the sidewalk getting ready to cross the road. The eye movements of the subjects looking at the pictures on the screen were collected through the eye tracker.The results showed that adults used a far more intense exploration of the useful visual field of view. They looked at all the different areas of the field of view more frequently and for a longer time. Another interesting point is that the children gazed at areas and elements that are irrelevant to a safe crossing but prove salient for various reasons. Implications for road safety training are discussed.
