PROMPTING PATRON SAFETY BELT USE AT A RESTAURANT

A reversal (ABABAB) design was used to assess the effects of a verbal prompt on safety belt use of restaurant patrons. A verbal prompt delivered by employees at the exit door resulted in an average increase of 20% in safety belt use by drivers leaving the restaurant. A previous study provided this type of antecedent immediately before supermarket patrons entered their vehicles. This effort demonstrates the effects of a verbal prompt with greater latency between the prompt and target response.     

Teaching preschool children to report suspicious packages to adults

Law enforcement agencies stress that public reporting of terror‐related crime is the predominant means for disrupting these actions. However, schools may be unprepared because the majority of the populace may not understand the threat of suspicious materials or what to do when they are found on school grounds. The purpose of this study was to systematically teach preschool children to identify and report suspicious packages across three experiments. In the first experiment, we used multiple exemplar training to teach children to identify the characteristics of safe and unsafe packages. In the second experiment, we taught participants to identify the locations where packages should be considered unsafe. Finally, in the third experiment, we used behavioral skills training to teach participants to avoid touching unsafe packages, leave the area where they were located, and report their discovery to an adult. Results suggest the participants quickly developed these skills. Implications for safety skills in young school children are discussed.     

Work support,psychological well-being and safety performance among nurses in Hong Kong

This study investigated the mediating role of psychological well-being between work support and safety performance of 314 Hong Kong nurses, using self-reported questionnaires. Results showed that psychological well-being mediated the effects of work support on safety performance. The findings illustrate that work support was an important element to improve psychological well-being. This could generate better safety performance of the nurses. Implications and limitations are discussed.     

Interaction between pedestrians and automated vehicles: A Wizard of Oz experiment

Automated vehicles (AVs) will be introduced on public roads in the future, meaning that traditional vehicles and AVs will be sharing the urban space. There is currently little knowledge about the interaction between pedestrians and AVs from the point of view of the pedestrian in a real-life environment. Pedestrians may not know with which type of vehicle they are interacting, potentially leading to stress and altered crossing decisions. For example, pedestrians may show elevated stress and conservative crossing behavior when the AV driver does not make eye contact and performs a non-driving task instead. It is also possible that pedestrians assume that an AV would always yield (leading to short critical gaps). This study aimed to determine pedestrians’ crossing decisions when interacting with an AV as compared to when interacting with a traditional vehicle. We performed a study on a closed road section where participants (N = 24) encountered a Wizard of Oz AV and a traditional vehicle in a within-subject design. In the Wizard of Oz setup, a fake ‘driver’ sat on the driver seat while the vehicle was driven by the passenger by means of a joystick. Twenty scenarios were studied regarding vehicle conditions (traditional vehicle, ‘driver’ reading a newspaper, inattentive driver in a vehicle with “self-driving” sign on the roof, inattentive driver in a vehicle with “self-driving” signs on the hood and door, attentive driver), vehicle behavior (stopping vs. not stopping), and approach direction (left vs. right). Participants experienced each scenario once, in a randomized order. This allowed assessing the behavior of participants when interacting with AVs for the first time (no previous training or experience). Post-experiment interviews showed that about half of the participants thought that the vehicle was (sometimes) driven automatically. Measurements of the participants’ critical gap (i.e., the gap below which the participant will not attempt to begin crossing the street) and self-reported level of stress showed no statistically significant differences between the vehicle conditions. However, results from a post-experiment questionnaire indicated that most participants did perceive differences in vehicle appearance, and reported to have been influenced by these features. Future research could adopt more fine-grained behavioral measures, such as eye tracking, to determine how pedestrians react to AVs. Furthermore, we recommend examining the effectiveness of dynamic AV-to-pedestrian communication, such as artificial lights and gestures.     

Motivating and deterring factors for two common traffic-rule violations of cyclists in Germany

Cyclists have a rather high risk of being injured in traffic accidents compared to motor vehicle occupants. Contributing factors leading to these crashes still need to be properly understood.Two online surveys were conducted concerning reasons, motives and likelihood for two common violations: riding on the wrong path (N = 198) and cycling without light in the dark (N = 755). Motivations for the infringements were examined by multiple linear regression models, including variables derived from the theory of planned behavior (Ajzen, 1991) and deterrence factors as predictors of the intention to infringe.Results show that reported motives for the violations differ. For cycling on the wrong cycling path, 55% of variance could be explained. The most influential motive was a positive attitude towards the infringement. Twenty-nine percent of variance could be explained by the model for cycling without light in the dark. Subjective norms and assumed deterrence factors were found to have very little influence on intended violations in both surveys. Participants’ rule-knowledge was found to be generally low. Participants reported perceived regulative discrimination and technical hurdles to hinder rule-compliant behavior. Overall, the findings suggest that a more comprehensive, educational approach is required to manage cyclists’ behavior.     

An observational study of restraint and helmet wearing behaviour in Malaysia

Unrestrained and unhelmeted occupants are at increased risk of severe injury or death in the event of a crash, and there is evidence that children, particularly in low and middle income countries, have low restraint and helmet wearing rates.Roadside observations of occupants of passing vehicles (7247 cars, vans and taxis and 2897 motorcycles) in nearside lanes were made at seven selected road sites located around the Klang Valley (greater Kuala Lumpur) area representing a variety of demographic locations.The findings revealed an overall low rate of seat-belt wearing in vehicles (front seat drivers: 44.6%; front seat adult passengers: 33.8%; front seat child passengers: 11.8%; rear seat adult passengers: 5.2%; and, rear seat child passengers: 5.8%). For motorcyclists, the majority of adult riders and pillions wore helmets (93.4% and 85.8%, respectively), however a substantial proportion (40%) did not fasten their helmet properly. Of children observed on motorcycles, only 30.5% wore helmets.This study shows low seat-belt and helmet wearing rates, despite enactment of legislation that requires all vehicle passengers to be restrained and for all motorcyclists to wear helmets. This was particularly evident for children (front and rear seating positions) and rear seat adult passengers. It is suggested there is a general lack of awareness of safety and the benefits of restraint/helmet use, and lack of adequate and appropriate enforcement. The implications of the findings are discussed in terms of promoting restraint/helmets use, enforcement of legislation and implementation of technologies to increase appropriate restraint/helmet use.     

Associations between self-reported mindfulness,driving anger and aggressive driving

Anger and aggression on the roads is associated with how drivers evaluate the driving situation and the behaviour of other drivers. Consequently, both can be exacerbated when these evaluations are made superficially and/or when drivers have pre-existing negative schemas regarding certain types of road situations or users. Mindfulness is likely to have negative associations with anger and aggression because it promotes opposing appraisals. That is, it encourages emotion-regulation and involves acceptance of, but not reaction to, the current situation. To examine these associations, a total of 309 drivers responded to an online questionnaire assessing mindfulness, driving anger and aggressive driving. The results showed that mindfulness shared negative relationships with driving anger and self-reported aggressive driving. However, when these relationships were examined simultaneously using Structural Equation Modelling, mindfulness was found to relate only to anger and this, in turn, predicted aggressive driving. Further analysis showed that driving anger mediates the relationship between mindfulness and aggressive driving. These results suggest that mindfulness training may provide a promising intervention for drivers prone to driving anger and subsequent aggression.     

Exploring traffic safety culture and drunk driving: An examination of the community and DUI related fatal crashes in the U.S. (1993–2015)

This project explores the relationship between structural level factors associated with community traffic safety culture toward alcohol and alcohol related fatal crashes in the United States from 1993 to 2015. Multilevel growth curve models were estimated to explore these relationships within longitudinal data. As hypothesized, increases in factors associated with anti-alcohol community norms, values, attitudes, and beliefs were related to decreases in alcohol related crashes at the county level. Conversely, measures associated with pro-alcohol factors were related to increased alcohol related crashes. These findings are consistent with traffic safety culture, social norms theory, and the Positive Community Framework (PCF).     

The effects of a job crafting intervention on the success of an organizational change effort in a blue-collar work environment

The current study in a blue-collar context investigates whether a job crafting intervention may facilitate employee adaptation to organizational change, while decreasing exhaustion and increasing positive attitudes towards change and safety behaviour. It was hypothesized that the intervention would increase job crafting behaviours (i.e., seeking resources, seeking challenges, and optimizing demands) resulting in decreased employee exhaustion, and improved change attitudes and employee safety behaviour (i.e., adherence to organization’s standard operating procedures). The quasi-experimental study revealed that, after the intervention (consisting of a workshop, four weeks of job crafting implementation, and an evaluative session), employees reported an increase in two of the three trained job crafting strategies (i.e., seeking challenges, optimizing demands). Moreover, those who participated in the intervention reported lower levels of exhaustion, improved cognitive and behavioural attitudes towards change, and increased safety behaviour. The intervention was found to improve the affective, cognitive, and behavioural components of a change attitude due to increases in seeking challenges. Results were similar after controlling for quality information and leadership behaviour during the change. It is concluded that a job crafting intervention and resulting job crafting behaviour can be an effective way to achieve successful adaptation to organizational change.     

Acceptance of visual and audio interventions for distracted pedestrians

Distraction from mobile devices increases pedestrian risks at intersections. Innovative interventions are currently installed at road and rail intersections to alert pedestrians. These interventions will be effective only if pedestrians modify their behaviour. The Technology Acceptance Model (TAM) posits that behaviour changes as a result of behavioural intention, which is affected by perceived usefulness and perceived ease of use. However, the link between intention and actual behaviour is often overlooked. The current study aims to investigate this link and apply this theoretical framework to interventions for distracted pedestrians. We conducted a day-time field study at three railway level crossings in New Zealand with such interventions reminding pedestrians to look for trains: in-ground flashing lights located at footpath level, an audio warning message, and in-ground flashing lights combined with the audio warning message. Participants (N = 34, Mean age 33.6, SD = 8.6 years) walked through level crossings while performing a distractor task (visual and auditory distraction) or when not distracted. Actively checking for trains from both sides of the crossing was used as a measure of actual behaviour. All three interventions were perceived as useful (5.1 ± 0.4) and easy to use (5.6 ± 0.2) and resulted in positive intention to use the technology (5.8 ± 0.3). Statistical analyses confirmed that the TAM constructs - particularly perceived usefulness - affected intention, and intentions lead to behavioural change with improved crossing behaviours. This study highlights the importance of perceived usefulness and intentions to use the interventions with reducing distracted pedestrian behaviours.
