    Sooner than later, the growing development of Autonomous Vehicles (AVs) will represent not only an imminent transformation of transportation dynamics, but also further advantages for their users, including many improvements in road crash prevention, efficiency and sustainability. However, different concerns and constraints may affect the intention of adopting this technology among its potential customers, especially for what concerns those constraints related to safety, viability and stability. The objective of this study was to examine the influence of perceived safety and value attributed to the AV in the drivers’ intention to use it, considering the drivers’ demographic factors, driving...

    Sooner than later, the growing development of Autonomous Vehicles (AVs) will represent not only an imminent transformation of transportation dynamics, but also further advantages for their users, including many improvements in road crash prevention, efficiency and sustainability. However, different concerns and constraints may affect the intention of adopting this technology among its potential customers, especially for what concerns those constraints related to safety, viability and stability. The objective of this study was to examine the influence of perceived safety and value attributed to the AV in the drivers’ intention to use it, considering the drivers’ demographic factors, driving habits, interaction with information technologies and self-reported safety records (using conventional vehicles) as potential predictors. For this cross-sectional study, data from 1205 drivers of conventional vehicles were analyzed through a structural equation modeling (SEM) approach. The intention to use autonomous vehicles could be predicted through demographic and driving-related factors, as well as by the level of interaction of individuals with information and communication technologies (ITCs). It was also found that the perceived safety of AVs and their attributed value for transport and road safety mediate the associations between drivers’ features and the final intention of using (or not) autonomous vehicles. The results of this study suggest that perceived safety and the value attributed to AVs significantly influence the intention of adopting it. In other words, a deeper emphasis on the safety, causality prevention and efficiency-related benefits may strengthen the acceptance of this new technology and enhance its progressive inclusion in transport dynamics among drivers.

    Well-being, behavioral patterns and cycling crashes of different age groups in Latin America: Are aging adults the safest cyclists?

    Sergio Useche, Francisco Alonso, Jaime Sanmartín, Luis Montoro, Boris Cendales

    (2019). Article

    PLoS ONE. Num.14(8): e0221864

    Objectives This study aimed at analyzing the cycling safety-related factors and the mental health indicators of elderly cyclists in comparison with other age groups. Methods For this cross-sectional study, we analyzed the data of 911 bicyclists from two Latin American countries that have been experiencing a substantial growth of urban cycling during the last few years: Colombia and Argentina. Participants responded to an e-questionnaire on bicycling behaviors, mental health and cycling safety. Results Aging adults reported lower rates of risky behaviors and traffic crashes (around .38 in five years), and, on the other hand, more cycling protective behaviors, a higher risk perception...

Participants responded to an e-questionnaire on bicycling behaviors, mental health and cycling safety. Results Aging adults reported lower rates of risky behaviors and traffic crashes (around .38 in five years), and, on the other hand, more cycling protective behaviors, a higher risk perception and a better knowledge of traffic norms than both other adults (26–50 years old) and young cyclists (<26). Cycling behaviors and crashes were found to be significantly related to mental health indicators, the latter being higher in aging cyclists. However, this population remains more prone to distractions experienced while cycling than other age groups. Conclusions Although the behavioral features of aging adults were comparatively “safer” than the ones displayed by other age groups, factors such as cycling distractions and this population’s over-representation in traffic crashes suggest the need of enforcing policymaking for a better integration of this age segment in alternative transportation dynamics.

    Trait driving anger and driving styles among Colombian professional drivers

    Sergio Useche, Boris Cendales, Francisco Alonso, Luis Montoro, Juan C. Pastor

    (2019). Article

    Heliyon. Num.5(8): e02259

    This study analyzes the association between trait driving anger and driving styles in a sample of Colombian professional drivers. Additionally, the internal and external validity of the Deffenbacher's Driving Anger Scale (DAS-14) was examined in the study population. The DAS-14 and the Spanish Version of the Multidimensional Driving Style Inventory (S-MDSI) were administered to 492 urban bus and taxi operators. Average trait driving anger scores in the study population were similar to those reported in previous validation studies from Spain, Argentina, China, and Malaysia. After deleting three cross-loaded items, confirmatory factor analyses revealed a three-dimensional latent structure for...

The DAS-14 and the Spanish Version of the Multidimensional Driving Style Inventory (S-MDSI) were administered to 492 urban bus and taxi operators. Average trait driving anger scores in the study population were similar to those reported in previous validation studies from Spain, Argentina, China, and Malaysia. After deleting three cross-loaded items, confirmatory factor analyses revealed a three-dimensional latent structure for the DAS-14, similar but not equal to the previous Spanish speaking validations. This factorial structure fits the data reasonably well. Finally, linear regression analyses revealed that the three factors of the DAS-14 (impeded progress by others, illegal driving, and direct hostility) significantly predict adaptive and maladaptive driving styles. Overall, the results of this study suggest that the DAS-14 is a reasonably reliable measure of driving anger traits among professional drivers, and it also provides relevant insights for the prevention of risky driving styles in this occupational group.

    Psychosocial Work Factors, Job Stress and Strain at the Wheel: Validation of the Copenhagen Psychosocial Questionnaire (COPSOQ) in Professional Drivers

    Sergio Useche, Luis Montoro, Francisco Alonso, Juan C. Pastor

    (2019). Article

    Frontiers in Psychology. Num.10:1531

    Introduction: Psychosocial work environment has been related to many negative health outcomes in different workforces. However, evidence in this regard is still limited in the case of transport workers, and most of the tools used in research, often excessively generic, do not fully consider the specific key stressors, and adverse issues present in the psychosocial environment of professional driving. Objective: Thus, the purpose of this study was to obtain a complete description of the validation of measurement applied to psychosocial factors at work in professional drivers, using the Enterprise version (2018) of COPSOQ-III.

    Introduction: Psychosocial work environment has been related to many negative health outcomes in different workforces. However, evidence in this regard is still limited in the case of transport workers, and most of the tools used in research, often excessively generic, do not fully consider the specific key stressors, and adverse issues present in the psychosocial environment of professional driving. Objective: Thus, the purpose of this study was to obtain a complete description of the validation of measurement applied to psychosocial factors at work in professional drivers, using the Enterprise version (2018) of COPSOQ-III. Methods: The data was collected from 726 Spanish professional drivers, and the analyses were conducted using the competitive Confirmatory Factor Analysis or CFA, obtaining basic psychometric properties and an optimized structure for the instrument applied to active transport workers. Results: The results suggest a clear factorial structure, high factorial weights, internal consistency, and an improved adjustment to the psychosocial conditions of this group, excluding a set of items with low psychometrical adjustment and keeping the five-factor structure of the questionnaire: demands, influence and development, interpersonal relationships and leadership, job insecurity, and strain-effects and outcomes. Conclusion: Overall, what was found in this study supports the hypothesis that the validated version of COPSOQ in professional drivers, together with complementary information sources specific for their work environment, may have a relevant research value and some important practical implications for the improvement of the occupational safety, and health within the typically vulnerable industry of transportation.

    Commuting Accidents of Spanish Professional Drivers: When Occupational Risk Exceeds the Workplace

    Javier Llamazares, Sergio Useche, Luis Montoro, Francisco Alonso

    (2019). Article

    International Journal of Occupational Safety and Ergonomics.

    Background. Work traffic accidents are an issue both in Spain and all over the world, and specific evidence on commuting accidents is scarce. Even though both industrial safety and welfare have been improved during the last decades, the commuting accidents rate is growing worldwide. Purpose. The aim of this study was to examine and describe the characteristics of commuting traffic crashes of Spanish professional drivers. Materials and methods. For this cross-sectional study, commuting accidents suffered by drivers during the last 12 years were analyzed. Crossed and heatmap-based analyses were performed in order to establish patterns and driver-based differences among commuting crashes....

For this cross-sectional study, commuting accidents suffered by drivers during the last 12 years were analyzed. Crossed and heatmap-based analyses were performed in order to establish patterns and driver-based differences among commuting crashes. Results. Commuting crashes’ features were found to be associated with demographic and job-related variables of professional drivers. Drivers’ gender, time slots (peak/off-peak hours) and the specific hour of the event explained different trends in accident severity and characteristics. Conclusions. The results of this study suggest that commuting accidents involving professional drivers differ in demographic and situational issues from general and on-duty professional drivers’ traffic crashes. Also, since in Spain commuting crashes are occupational accidents, more numerous and better actions should be taken in this regard, especially considering the association of professional drivers’ accidents with fatigue and shift-working.

    Healthy but risky: A descriptive study on cyclists’ encouraging and discouraging factors for using bicycles, habits and safety outcomes.

    Sergio Useche, Luis Montoro, Jaime Sanmartin, Francisco Alonso.

    (2019). Article

    Transportation Research Part F. Num.62:587-598

    Transportation is a necessary process that requires not only adequate means, but also indi- vidual choices. And apparently, the recent boom of alternative modes of transportation has substantially changed people’s perceptions of cycling, as well as the reasons why they decide to use a bike. Nevertheless, people identify some motives that encourage this use together with the perceived risks and the discouraging factors which affect the choice of using a bike, thus making it important to explore all these elements in the light of the empirical evidence. The objective of this study was to explore and describe the encouraging and discouraging reasons behind the use of bikes among cyclists,...

    Transportation is a necessary process that requires not only adequate means, but also indi- vidual choices. And apparently, the recent boom of alternative modes of transportation has substantially changed people’s perceptions of cycling, as well as the reasons why they decide to use a bike. Nevertheless, people identify some motives that encourage this use together with the perceived risks and the discouraging factors which affect the choice of using a bike, thus making it important to explore all these elements in the light of the empirical evidence. The objective of this study was to explore and describe the encouraging and discouraging reasons behind the use of bikes among cyclists, together with the reasons behind their journeys and the relationship of these elements with their crash history. For this study, 1064 cyclists were asked to complete an electronic survey which gathered information on their cycling-related habits, perceptions and motives. The results show that physical health and fitness (38%), contribution to environmental sustainability (14%), econ- omy (13%) and time saving (10%) were the most frequent factors which encouraged cycling. On the other hand, perceived crash risk (17%), adverse weather conditions (17%) and lack of safety (16%) were found to be the most relevant discouraging factors. Finally, participants who cycled with more regularity were found to be less prone to suffer cycling crashes. The findings of this study support that cycling is a choice based on both benefits and risks, and its perceived connection to health is highly prevalent among active cyclists. Furthermore, perceived risks which may discourage cycling are an issue that needs to be addressed by transport policies, in order to enhance the engagement of the population in this mode of transportation. Also, this study highlights the need to strengthen utility cycling (cycling for transport to and from places) as a way to integrate transportation within healthier practices and habits.

    Explaining self-reported traffic crashes of cyclists: An empirical study based on age and road risky behaviors

    Sergio Useche, Francisco Alonso, Luis Montoro, Cristina Esteban.

    (2019). Article

    Safety Science. Num.113:105-114

    The growing rates of traffic crashes involving cyclists are currently recognized as a major public health and road safety concern. Furthermore, risky behaviors on the road and their precedent factors have been conceptualized as potential determinants for explaining, intervening and preventing traffic injuries of cyclists. Objectives: This study aimed at examining whether individual factors and self-reported risky behaviors could explain the crash rates of cyclists in a period of 5 years. Methods: A sample of 1064 cyclists was used, with a mean age of 32.83 years. Participants answered a survey assessing demographic data and information on risky behaviors, risk perception, knowledge of...

    The growing rates of traffic crashes involving cyclists are currently recognized as a major public health and road safety concern. Furthermore, risky behaviors on the road and their precedent factors have been conceptualized as potential determinants for explaining, intervening and preventing traffic injuries of cyclists. Objectives: This study aimed at examining whether individual factors and self-reported risky behaviors could explain the crash rates of cyclists in a period of 5 years. Methods: A sample of 1064 cyclists was used, with a mean age of 32.83 years. Participants answered a survey assessing demographic data and information on risky behaviors, risk perception, knowledge of norms, and suffered cycling crashes. Results: Using Structural Equation Models, it was found that crash rates in cyclists could be explained through risky behaviors, risk perception, knowledge of traffic norms and cycling intensity. Through a multi-group path model differentiating cyclists by age group, it was also found that cycling intensity has a differential impact on self-reported crashes in older (age > 25) and younger (age<=25) cyclists. Conclusions: This study suggests that risky behaviors mediate the relationship between the individual factors and the crash rates of cyclists, and that age exerts an important effect in the variation of the explanatory structure of the model. The design of educational tools would be useful for promoting not only the avoidance of risky behaviors, but also a generalized awareness on road safety issues. Practical applications: This research provides an empirical precedent in the study of the impact of factors related to risky behaviors on the road and to safety outcomes of cyclists.

    Conceptualization of aggressive driving behaviors through a Perception of aggressive driving scale (PAD)

    Francisco Alonso, Cristina Esteban, Luis Montoro, Andrea Serge

    (2019). Article

    Transportation Research Part F. Num.60:415–426

    Research on traffic safety has highlighted the importance of studying and intervening in aggressive driving in order to reduce crashes and accidents. The main objective of this work is to describe the perception of what people consider an aggressive behavior, and their per- ception of which are the most aggressive acts performed when driving. The sample was composed of 1079 Spanish drivers aged over 14. They participated in a national telephone survey, completing a questionnaire which gathered socio-demographic data and informa- tion on the drivers’ profiles, containing a ‘‘Perception of aggressive driving Scale (PAD)”. The unifactorial ANOVA test for repeated measures of the General Linear...

    Research on traffic safety has highlighted the importance of studying and intervening in aggressive driving in order to reduce crashes and accidents. The main objective of this work is to describe the perception of what people consider an aggressive behavior, and their per- ception of which are the most aggressive acts performed when driving. The sample was composed of 1079 Spanish drivers aged over 14. They participated in a national telephone survey, completing a questionnaire which gathered socio-demographic data and informa- tion on the drivers’ profiles, containing a ‘‘Perception of aggressive driving Scale (PAD)”. The unifactorial ANOVA test for repeated measures of the General Linear Model (GLM) with a = 0.05 procedure was used for the comparison of mean values. Results show that drivers tend to make higher valuations regarding the aggressive character of the PAD (M = 7.86 SD = 0.05). The situation that most concerned Spanish drivers was ‘‘To produce damage to other people with some type of object or weapon” (M = 9.47 SD = 0.05), which does not necessarily correspond to the driving context. Differences in perception were found depending on socio-demographic variables. Women, drivers over 29years old, low- middle social classes, and drivers who had suffered two accidents, tended to evaluate PAD as more aggressive. These findings suggest that differences in the perception of aggressive behaviors depend on social situations and on the driver’s personal features. Finally, the findings of this research will help road safety researchers understand the con- cept of aggressiveness under different perspectives, and take into account the existing dif- ferences between dangerous and punishable behaviors. Moreover, these outcomes showed the necessity to deepen the research on those behaviors that Spaniards perceive as aggres- sive, and to develop knowledge on why the perception of aggressiveness changes according to the characteristics of the population, and how this perception is reflected in people’s attitudes and behaviors towards road safety.

    Work stress and health problems of professional drivers: a hazardous formula for their safety outcomes.

    Sergio Useche, Boris Cendales, Luis Montoro, Cristina Esteban.

    (2018). Article

    PeerJ. Num.6:e6249

    Background: Several empirical studies have shown that professional drivers are a vulnerable occupational group, usually exposed to environmental stressors and adverse work conditions. Furthermore, recent studies have associated work-related stress with negative job performances and adverse health outcomes within this occupational group, including cardiovascular diseases and unsafe vehicle operation. Objective: The aim of this study was to describe the working conditions and the health status of this occupational group, and to evaluate the association between the Demand–Control model of job stress and their self-reported health and safety outcomes. Methods: A pooled sample of 3,665...

    Background: Several empirical studies have shown that professional drivers are a vulnerable occupational group, usually exposed to environmental stressors and adverse work conditions. Furthermore, recent studies have associated work-related stress with negative job performances and adverse health outcomes within this occupational group, including cardiovascular diseases and unsafe vehicle operation. Objective: The aim of this study was to describe the working conditions and the health status of this occupational group, and to evaluate the association between the Demand–Control model of job stress and their self-reported health and safety outcomes. Methods: A pooled sample of 3,665 Colombian professional drivers was drawn from five different studies. The Job Content Questionnaire and the General Health Questionnaire were used to measure work stress and self-reported mental health, respectively. Additionally, professional drivers self-reported health problems (hypertension, dyslipidemia, diabetes and overweight) and health-related risky behaviors (smoking and sedentary behavior). Results: Regarding the Job Demands–Control (JDC) model, it was found that approximately a third part of Colombian professional drivers suffer from high job strain (29.1%). Correlational and multivariate analyses suggest that de JDC model of stress is associated with the professional drivers’ mental health, traffic accidents and fines, but not with other physical and behavioral health-related outcomes, which are highly prevalent among this occupational group, such as hypertension, dyslipidemia, diabetes, overweight, smoking and sedentary behavior. Conclusion: The results of this study suggest that (a) stressful working conditions are associated with health and lifestyle-related outcomes among professional drivers, and (b) that evidence-based interventions are needed in order to reduce hazardous working conditions, job stress rates and their negative impact on the health of this occupational group
