Development and validation of the Spanish Hazard Perception Test.
2014
The aim of the current study is to develop and obtain valid evidence for a hazard perception test suitable for the Spanish driving population. To obtain valid evidence to support the use of the test, the effect of hazardous and quasi-hazardous situations on the participants' hazard prediction is analyzed and the pattern of results for drivers with different driving experience--that is, learner, novice, and expert drivers and reoffender vs. nonoffender drivers--is compared. Potentially hazardous situations are those that develop without involving any real hazard (i.e., the driver did not actually have to decelerate or make any evasive maneuver to avoid a potential collision). The current stu…
Modeling offenses among motorcyclists involved in crashes in Spain.
2013
In relative terms, Spanish motorcyclists are more likely to be involved in crashes than other drivers and this tendency is constantly increasing. The objective of this study is to identify the factors that are related to being an offender in motorcycle accidents. A binary logit model is used to differentiate between offender and non-offender motorcyclists. A motorcyclist was considered to be offender when s/he had committed at least one traffic offense at the moment previous to the crash. The analysis is based on the official accident database of the Spanish general directorate of traffic (DGT) for the 2003–2008 time period. A number of explanatory variables including motorcyclist character…
Inhibiting and Facilitating Factors to End a Violent Relationship: Patterns of Behavior Among Women in Spain
2013
The objective of this study are (a) to explore the factors, which facilitate or inhibit women’s responses to intimate partner violence (IPV) and their ability to leave a violent relationship; (b) to identify patterns of behavior in abused women based on their perception of the violence and the actions they take to find help or a solution to the problems derived from IPV. Semistructured interviews were carried out. The critical path is defined as the sequence of decisions and actions taken by affected women to address the violence they experienced. Based on this concept, we identified several factors that affect women’s responses to violence, and categorized them into inhibiting and facilita…
Arrival-time judgments on multiple-lane streets: the failure to ignore irrelevant traffic
2014
How do road users decide whether or not they have enough time to cross a multiple-lane street with multiple approaching vehicles? Temporal judgments have been investigated for single cars approaching an intersection; however, close to nothing is known about how street crossing decisions are being made when several vehicles are simultaneously approaching in two adjacent lanes. This task is relatively common in urban environments. We report two simulator experiments in which drivers had to judge whether it would be safe to initiate street crossing in such cases. Matching traffic gaps (i.e., the temporal separation between two consecutive vehicles) were presented either with cars approaching o…
Another look at safety climate and safety behavior: deepening the cognitive and social mediator mechanisms.
2012
WOS:000301081700053 (Nº de Acesso Web of Science) “Prémio Científico ISCTE-IUL 2013” In this study, safety climate literature and the theory of planned behavior were combined to explore the cognitive and social mechanisms that mediate the relationship between organizational safety climate and compliance and proactive safety behaviors. The sample consisted of 356 workers from a transportation organization. Using a multiple mediation design, the results revealed that proactive and compliance safety behaviors are explained by different patterns of combinations of individual and situational factors related to safety. On the one hand, the relationship between organizational safety climate and pr…
A multi-agent safety response model in the construction industry.
2014
BACKGROUND: The construction industry is one of the sectors with the highest accident rates and the most serious accidents. A multi-agent safety response approach allows a useful diagnostic tool in order to understand factors affecting risk and accidents. The special features of the construction sector can influence the relationships among safety responses along the model of safety influences. OBJECTIVE: The purpose of this paper is to test a model explaining risk and work-related accidents in the construction industry as a result of the safety responses of the organization, the supervisors, the co-workers and the worker. METHODS: Sample: 374 construction employees belonging to 64 small Spa…
Can We Study Autonomous Driving Comfort in Moving-Base Driving Simulators? A Validation Study.
2016
Objective: To lay the basis of studying autonomous driving comfort using driving simulators, we assessed the behavioral validity of two moving-base simulator configurations by contrasting them with a test-track setting. Background: With increasing level of automation, driving comfort becomes increasingly important. Simulators provide a safe environment to study perceived comfort in autonomous driving. To date, however, no studies were conducted in relation to comfort in autonomous driving to determine the extent to which results from simulator studies can be transferred to on-road driving conditions. Method: Participants ( N = 72) experienced six differently parameterized lane-change and de…
Pleasant music as a countermeasure against visually induced motion sickness.
2013
Visually induced motion sickness (VIMS) is a well-known side-effect in virtual environments or simulators. However, effective behavioral countermeasures against VIMS are still sparse. In this study, we tested whether music can reduce the severity of VIMS. Ninety-three volunteers were immersed in an approximately 14-minute-long video taken during a bicycle ride. Participants were randomly assigned to one of four experimental groups, either including relaxing music, neutral music, stressful music, or no music. Sickness scores were collected using the Fast Motion Sickness Scale and the Simulator Sickness Questionnaire. Results showed an overall trend for relaxing music to reduce the severity o…
Concomitant dental injuries in maxillofacial fractures - a retrospective analysis of 1219 patients
2014
BACKGROUND/AIM: Traumatic dental injuries are frequently combined with maxillofacial fractures, but literature addressing this topic is rare. In a retrospective study, the frequency of dental lesions in inpatients with traumatic facial injuries was analyzed. MATERIAL AND METHODS: All patients referred to the Department of Oral and Maxillofacial Surgery of the University Medical Center of the Johannes Gutenberg-University Mainz for inpatient treatment due to facial fractures between January 2001 and December 2007 were analyzed regarding the type of fracture, its localization, and potential concomitant dental injuries. In addition a systematic review was performed to compare the findings of t…
Rifle-balancing in precision shooting:behavioral aspects and psychophysiological implication
2007
This study investigated sharpshooters' strategies to control their rifle stability during the aiming period. Six elite and six pre-elite shooters completed a simulated realistic shooting task (laser rifle), and their performance was evaluated from behavioral and psychophysiological perspectives. The analysis of the rifle's barrel movement, indexing the shooter's behavioral performance, supported the view that rifle-balancing is an essential determinant of superior shooting performance. The psychophysiological data, i.e. the brain slow potentials, suggested that the shooters applied different rifle-hold strategies; the elite shooters concentrated primarily on achieving a stable rifle positio…
