A First Step toward the Understanding of Implicit Learning of Hazard Anticipation in Inexperienced Road Users Through a Moped-Riding Simulator

Hazard perception is considered one of the most important abilities in road safety. Several efforts have been devoted to investigating how it improves with experience and can be trained. Recently, research has focused on the implicit aspects of hazard detection, reaction, and anticipation. In the present study, we attempted to understand how the ability to anticipate hazards develops during training with a moped-riding simulator: the Honda Riding Trainer (HRT). Several studies have already validated the HRT as a tool to enhance adolescents\u2019 hazard perception and riding abilities. In the present study, as an index of hazard anticipation, we used skin conductance response (SCR), which has been demonstrated to be linked to affective/implicit appraisal of risk. We administered to a group of inexperienced road users five road courses two times a week apart. In each course, participants had to deal with eight hazard scenes (except one course that included only seven hazard scenes). Participants had to ride along the HRT courses, facing the potentially hazardous situations, following traffic rules, and trying to avoid accidents. During the task, we measured SCR and monitored driving performance. The main results show that learning to ride the simulator leads to both a reduction in the number of accidents and anticipation of the somatic response related to hazard detection, as proven by the reduction of SCR onset recorded in the second session. The finding that the SCR signaling the impending hazard appears earlier when the already encountered hazard situations are faced anew suggests that training with the simulator acts on the somatic activation associated with the experience of risky situations, improving its effectiveness in detecting hazards in advance so as to avoid accidents. This represents the starting point for future investigations into the process of generalization of learning acquired in new virtual situations and in real-road situations

Accidental injury, risk-taking behaviour and the social circumstances in which young people (aged 12-24) live: a systematic review

In industrialised countries such as England and Wales, unintended injury (which ranges from sprains in sport to hospitalisation and death due to drugs or transport crashes) is the leading cause of death in children aged 0 to 14 years, and a major cause of death in young adults aged 15 to 24. It is also a major cause of ill health and disability in these age groups. There is a large body of research on young people and their perceived propensity to take risks. Common sense suggests that an increased willingness to place oneself at risk will result an increased likelihood of physical injury. However, given that pathways to injury are complex and not always well understood, the UK Department of Health commissioned a large systematic review to examine this multifaceted issue. Drug use • The review found that the use of drugs is associated with an increased risk of accidental death among young people and that 12–24 year olds are less at risk than those immediately older. However, risk of death increases with length of drug use, so there is value in targeting interventions at this age group. • Many more young men than women die from drug overdoses, because more men take drugs, but those women who do use drugs are at higher risk. Certain other groups of young people are more at risk than others. These include young people in deprived areas and men who have recently been released from prison. • There was a clear disjunction of views between young people who used drugs and those who did not. The young people who did not take drugs regarded them as risky and stated that media images about possible negative consequences dissuaded them from trying them, while those who did tended not to believe ‘official’ messages about possible harms and did not perceive taking drugs as being dangerous. Cannabis in particular was singled out as possibly being good for you, with some young people believing it to be cheaper than alcohol. The recent reclassification of cannabis and the subsequent debate may have helped to reinforce this view. • The burden of the more serious injuries – as demonstrated by the mortality statistics – is carried by young people in the lower socio-economic groups. • In road injuries, drugs are found in the bloodstream of more young fatal accident victims than older age groups; however, it is difficult to assess whether drugs actually contributed to the accident. • Driving on cannabis was thought to be more acceptable than drink-driving and not thought to be dangerous. Alcohol use • Almost everyone admitted to hospital for alcohol poisoning is aged between 11 and 17. After a sharp peak among 14 and 15 year olds, hospital admissions for injuries with alcohol involvement decline slowly between the ages of 16 and 30. • Correlational studies have shown that alcohol puts the drinker at an increased risk of injury, that young people are more likely to have injuries than older people, and that young men are more at risk than young women. In the one study that examined ethnicity, minority ethnic status did not increase alcohol-related injuries, and may in fact have had a protective association. • Views studies found that young people say that they do not commonly mix alcohol and other drugs. Most young people reported that drinking places them at greater risk of injury, though some did not. The younger teenagers – 14 and 15 year olds – felt most in danger of injury when drinking. Young people felt that they learned to manage their drinking through experience and that unsupervised, outdoor drinking was the most dangerous and was more common among younger teenagers (with injuries being considered less common in licensed venues). Peers encourage both drinking and drunken pranks, but also protect one another when they have become more vulnerable as a result of drink. Young people felt that drinking reduces their perceptions of danger and some stated that injury as a result was inevitable. Most young people were cautious about getting very drunk, though being sick as a result of drinking is common and not regarded as serious. Bad experiences – whether to self or someone else – might change behaviour in the short- but not long-term. • One study which examined attempts to reduce alcohol-related injuries found some evidence that motivational interviews in A&E departments are more effective than information handouts. Drink-driving • Drink-driving was generally considered dangerous and not socially acceptable, whereas driving on cannabis was more acceptable and not thought to be dangerous. Some young people stated that a lack of public transport (or alternatives, such as taxis) made it more likely that they would drink and drive. • Interventions based on models of behaviour change to reduce drink-driving are ineffective or have a negative effect. Combining different approaches has more effect than using a single approach. Education or skills training has either negative or no effects on driver behaviour and subsequent accidents, possibly because these approaches lead to over-confidence or early licensing. • Legislation and enforcement on reducing drink-driving has been found to be effective

The Impact of Human Error in the Use of Agricultural Tractors: A Case Study Research in Vineyard Cultivation in Italy

Recently, standards and regulations concerning occupational safety have become more and more rigorous. Nevertheless, the number of accidents and victims has not decreased significantly, as reported by official statistics. In Italy, the agricultural sector is certainly one of the most affected by this situation, especially taking into account the occurrence of serious injuries and fatalities related to the use of tractors. The main reasons for such a situation can be ascribed to the peculiarities of agricultural operations. Therefore, when analyzing the root causes of agricultural accidents, a user-centered approach is needed in order to make the development of health and safety interventions easier and more effective. Based on this, the present paper proposes a practical case study research focused on integrating the factor of human error into the risk assessment procedures of agricultural activities in vineyard cultivation. Such an approach allowed us to consider the impact of human errorwhile performing work activities (e.g., the use of a tractor)on hazards and related hazardous events in a thorough manner. The proposed approach represents a novelty in the sector of the safety assessment of agricultural activities, providing a first valuable basis for further analysis and implementation by researchers and practitioners

Personality traits and beliefs about peers\u2019 on-road behaviors as predictors of adolescents\u2019 moped-riding profiles.

Several efforts aimed at discriminating between different degrees of on-road risky attitudes have been devoted to the identification of personality profiles among young drivers. However, the results are often inconsistent because of the limits of selfreport measures. To overcome these limits, we tried to identify different profiles based on our study participants\u2019 driving performances in a virtual environment and to look for psychological predictors of inclusion in one of three profiles. One-hundred and fourteen inexperienced adolescents were involved in this study, which included two experimental sessions. During the first, before riding along five virtual courses on a moped simulator, participants\u2019 sensation seeking, locus of control, aggressiveness and beliefs about their peers\u2019 on-road behaviors were measured by means of self-report tools. During the second session, the participants drove the simulator along six courses that were different from those faced in the first session. A cluster analysis was run on a wide number of indexes extracted from the participants\u2019 performances to detect different riding profiles. Three profiles emerged (Imprudent, Prudent and Insecure), with specific riding patterns. The profiles also differed in terms of riding safety, assessed by means of the scores automatically given by the simulator to the participants\u2019 performances. Reporting an external locus of control, underestimating peers\u2019 on-road risky behaviors and showing less concern for fate among the possible causes of crashes are predictors that increase the risk of being included in the Imprudent profile. Low levels of dangerous thrill seeking predict inclusion in the Prudent profile, whereas high rates of self-reported anger play a role in discriminating the Insecure riders from the other profiles. The study indicates that it is possible to identify riding profiles with different degrees of on-road safety among inexperienced adolescents by means of simulated road environments. Moreover, inclusion in these profiles is predicted by different patterns of personality variables and beliefs. Further research is needed to verify the validity of these conclusions in real road conditions

Introducing a multivariate model for predicting driving performance: The role of driving anger and personal characteristics

Introduction: Maladaptive driving is an important source of self-inflicted accidents and this driving style could include high speeds, speeding violations, and poor lateral control of the vehicle. The literature suggests that certain groups of drivers, such as novice drivers, males, highly motivated drivers, and those who frequently experience anger in traffic, tend to exhibit more maladaptive driving patterns compared to other drivers. Remarkably, no coherent framework is currently available to describe the relationships and distinct influences of these factors. Method: We conducted two studies with the aim of creating a multivariate model that combines the aforementioned factors, describes their relationships, and predicts driving performance more precisely. The studies employed different techniques to elicit emotion and different tracks designed to explore the driving behaviors of participants in potentially anger-provoking situations. Study 1 induced emotions with short film clips. Study 2 confronted the participants with potentially anger-inducing traffic situations during the simulated drive. Results: In both studies, participants who experienced high levels of anger drove faster and exhibited greater longitudinal and lateral acceleration. Furthermore, multiple linear regressions and path-models revealed that highly motivated male drivers displayed the same behavior independent of their emotional state. The results indicate that anger and specific risk characteristics lead to maladaptive changes in important driving parameters and that drivers with these specific risk factors are prone to experience more anger while driving, which further worsens their driving performance. Driver trainings and anger management courses will profit from these findings because they help to improve the validity of assessments of anger related driving behavior

The ‘frontal lobe’ project: A double-blind, randomized controlled study of the effectiveness of higher level driving skills training to improve frontal lobe (executive) function related driving performance in young drivers

The current study was undertaken in order to evaluate the effectiveness of higher level skills training on safe driving behaviour of 36 teenage drivers. The participants, who attended the Driver Training Research camp in Taupo (NZ) over a two week period, were 16 to 17 years old and had a valid restricted driver licence. The study focused on four main aims. Firstly, the behavioural characteristics of the sample and their attitudes to risk taking and driving were examined. Results showed that speeding was the most anticipated driving violation, and high levels of confidence were associated with a higher number of crashes and a greater propensity for risk taking. Many, often male participants, also rated their driving skills as superior to others and thought they would be less likely than others to be involved in an accident. Secondly, the relationship between driving performance and executive functioning, general ability and sustained attention was evaluated. Overall, better driving performance and more accurate self-evaluation of driving performance was related to higher levels of executive functions, in particular, working memory, and cognitive switching. In addition, higher general ability and greater ability to sustain attention were also linked to better performance on the driving related assessments. The third focus of this study was to compare the effects of both, higher level and vehicle handling skills training on driving performance, confidence levels and attitudes to risk. While both types of training improved direction control, speed choice and visual search, along with number of hazards detected and actions in relation to hazards, statistically significant improvement on visual search was seen only after higher level skills training. Vehicle handling skills training significantly improved direction control and speed choice. In addition, confidence levels in their driving skills were significantly lowered and attitudes to speeding, overtaking and close following had improved significantly in the participants after the higher level driving skills training. The final aspect to this study was to examine the effects of the training over the following 6 month period based on self-reported driving behaviour. The response rate of participants however, was not sufficient to reach any meaningful conclusion on any long-term training effects. A pilot study using GPSbased data trackers to assess post-training driving behaviour revealed some promising results for future driver training evaluation studies. The overall implications of the results are discussed in relation to improving the safety of young drivers in New Zealand
