Driving simulators have become an important tool in human factors research, given that they are appropriately validated. Therefore, this study aims to explore the behavioral (absolute and relative) validity of a fixed-base driving simulator by analyzing different driving behavior measures such as speed, longitudinal acceleration, lateral acceleration, and brake pedal force. Thirty professional drivers participated in the experiment and the data was collected in real and simulated worlds under No Time Pressure (NTP) and Time Pressure (TP) driving conditions. Initially, comparative analyses were conducted on different driving behavior measures using Wilcoxon-signed rank test to examine absolute validity of the driving simulator. Finally, Generalized Linear Mixed (GLM) models were developed for computing the effective distance between real and simulated worlds by quantifying the parameters and for establishing relative validity. In general, the continuous profiles of driving behavior measures followed similar trends in real and simulated worlds and comparative analyses indicated relative validity of the driving simulator. The GLM models showed significant interaction effect of driving environments (real-world and simulated world) and driving conditions (NTP and TP) where high driving speed, high brake pedal force, and low lateral acceleration were observed in simulated world under TP driving condition than real-world under TP driving condition. Overall, the statistical analyses showed qualitative correspondence (relative validity) of the driving behavior measures in between real and simulated worlds. The findings from the current study showed expediency of the driving simulator and its effectiveness in conducting research on human factors and driver safety. 相似文献

Future traffic will be composed of both human-driven vehicles (HDVs) and automated vehicles (AVs). To accurately predict the performance of mixed traffic, an important aspect is describing HDV behavior when interacting with AVs. A few exploratory studies show that HDVs change their behavior when interacting with AVs, being influenced by factors such as recognizability and driving style of AVs. Unsignalized priority intersections can significantly affect traffic flow efficiency and safety of the road network. To understand HDV behavior in mixed traffic at unsignalized priority T-intersections, a driving simulator experiment was set up in which 95 drivers took part in it. The route in the driving simulator included three T-intersections where the drivers had to give priority to traffic on the major road. The participants drove different scenarios which varied in whether the AVs were recognizable or not, and in their driving style (Aggressive or Defensive). The results showed that in mixed traffic having recognizable aggressive AVs, drivers accepted significantly larger gaps (and had larger critical gaps) when merging in front of AVs as compared to mixed traffic having either recognizable defensive AVs or recognizable mixed AVs (composed of both aggressive and defensive). This was not the case when merging in front of an HDV in the same scenarios. Drivers had significantly smaller critical gaps when driving in traffic having non-recognizable aggressive AVs compared to non-recognizable defensive AVs. The findings suggest that human drivers change their gap acceptance behavior in mixed traffic depending on the combined effect of recognizability and driving style of AVs, including accepting shorter gaps in front of non-recognizable aggressive AVs and changing their original driving behavior. This could have implications for traffic efficiency and safety at such priority intersections. Decision makers must carefully consider such behavioral adaptations before implementing any policy changes related to AVs and the infrastructure. 相似文献

Social exclusion—being rejected or ignored by individuals or groups—is a common and adverse experience in social life. As a social activity, driving behaviour can be influenced by many factors. Whether social exclusion is one of these factors is an open question. Therefore, the aim of this study is to explore the impact of the social exclusion experience on individuals and their driving behaviours and the mediating effect of prosocial tendencies and driving anger. A total of 240 (104 males and 136 females) participants from China completed a questionnaire including the Ostracism Experiences Scale (OES), the prosocial tendencies measure (PTM), the Driving Anger Scale (DAS) and the Driver Behaviour Questionnaire (DBQ). The hierarchical multiple regression analysis and pathway analysis results showed that social exclusion experience and driving anger positively predicted aberrant driving behaviours (including aggressive violations, ordinary violations, lapses and errors), while prosocial tendencies had a negative impact on aberrant driving behaviour. Moreover, prosocial tendencies and driving anger mediated the relationship between social exclusion and driver behaviour, accounting for 11.18% and 46.71% of the total effect, respectively. The chain-mediated effect of prosocial tendencies and driving anger was also significant, accounting for 5.26% of the total effect of social exclusion on driver behaviour. This study examines the mechanisms underlying social exclusion experiences that positively predict individuals' unsafe driving behaviours, thereby filling a gap in social exclusion research and suggesting new avenues of exploration into the personal and social influences that affect driving behaviours. 相似文献

Emotions during driving have an essential impact on driving safety. This study aims to explore the relationships among emotional intelligence, emotional regulation, driving anger and related behaviour. A total of 304 drivers (aged 18–57) completed online questionnaires, including the trait emotional intelligence (TEI) scale, difficulties in emotional regulation scale (DERS), driving anger scale (DAS) and driver anger expression inventory (DAX). The results showed that the influence of TEI on maladaptive driving anger expression was negative, and individuals with higher emotional intelligence showed less maladaptive expressions of driving anger. Difficulties in emotion regulation played a mediating role between emotional intelligence and driving anger. These results suggest that drivers with high emotional intelligence and emotion regulation may face driving situations calmly and with a high level of driving safety. 相似文献

Anger and aggression on the road may sometimes appear unprovoked and unrelated to current driving circumstances. It is unclear whether such anger and aggression arises because of events prior to those circumstances in which anger is experienced and aggression is exhibited. In this study, time pressure and enforced following of a slowly moving vehicle were used to increase drivers’ anger in order to assess whether affect and behaviour during a subsequent, non-provocative, drive would change accordingly. Ninety-six drivers drove twice in a simulated urban environment. During the first drive, oncoming traffic and a slowly moving lead vehicle required that half of the drivers travelled far slower than they would choose. During the second drive, drivers again followed slower vehicles and were required to respond to traffic events not encountered in the manipulation drive. Mood (Profile of Mood States) was assessed before and after each drive, and anger evaluations, arousal (heart rate) and behaviour (speed, lane position and collisions) were measured during drives. Anger increased and both mood and driving behaviour deteriorated in drivers exposed to slower lead vehicles, compared with control group drivers. These behavioural differences of speed and lane positioning carried over into the subsequent drive even to driving situations unlike those where provocation had previously occurred. Drivers who had previously been impeded later approached hazards with less caution, and attempted more dangerous overtaking manoeuvres. It is concluded that sometimes dangerous driving may result from anger provoked by circumstances other than those in which the behaviour is exhibited. 相似文献

Summary An empirical review and critique of existing state standards for batterer programs in the domestic violence field appeared timely, given the current debate about their status and utility. Although there has been a considerable amount of polemic discussion of the topic, relatively limited data have been reported. The present article surveyed the content of standards developed in 30 states within the United States. Five categories of interest were examined including: (1) the minimum length of treatment specified; (2) specification of treatment orientation, methods, and content; (3) preferred or allowable modalities of treatment; (4) whether research findings were mentioned or endorsed as a basis for development of treatment standards; and (5) methods for developing and revising standards. A related area, the minimum education required for providers, was also included as an area of interest to further describe the current pool of practitioners targeted for regulation. An analysis of the content of these standards was then performed with regard to existing peer-reviewed research in the field. The results are discussed in terms of the strengths and weaknesses of current standards, the areas in which further research is needed, and specific recommendations regarding steps that might be taken to improve existing efforts. 相似文献

Summary Competence in mental health is explored in many roles, including that of researcher, author, teacher, supervisor, therapist, evaluator, consultant, forensic specialist, case manager, and administrator. It is viewed not only as a construct but also as an ongoing process within the individual. Five fundamental areas are examined: (1) Maintaining high standards of competence, (2) keeping within one's boundaries of competence and limitations of one's expertise, (3) maintaining competence in human diversity in practice and research, (4) engaging in continuing education in scientific and professional areas, and (5) protecting the welfare of others when standards are lacking. Guidance is also received from ethics codes, published standards of practice, federal and state laws, and institutional policies and regulations. 相似文献

ABSTRACT A text by Martin Niemoller which begins “When the Nazis came for the Communists …” has been widely quoted, but its text varies greatly and the date and original audience have been uncertain. This article examines the evidence and concludes that the most probable original version, which differs from most versions by having no mention of the Jews, was published in an article by Niemoller in 1979. This text was probably first spoken in the context of Niemoller's political activism in the late 1950s or 1960s. The various developments in the famous text can then be explained by principles of oral (or semi-oral) transmission of texts. 相似文献

BackgroundAs road complexity increases the requirement for number of road signs also increases, although the amount of road side space does not. One practical strategy to address this is to present multiple road signs on the same gantry (sign co-location). However, there is very little research on the safety implications of this practice.Method36 participants (mean age = 42.25 years, SD = 13.99, 18 females) completed three driving simulator scenarios, each scenario had a different sign co-location condition: no co-location, dual co-location and triple co-location. Each scenario presented similar information using direction signs, variable message signs and variable speed limit signs, under. Each drive included standard motorway driving (100 km/h speed zone) in free flow traffic and one emergency event where a lead vehicle suddenly braked. The scenario order was counterbalanced and the emergency event vehicle varied.ResultsOverall, there was no impact of co-locating signs on general driving performance. No significant difference was observed between conditions for reaction time and minimum headway in response to the emergency event. Participants were able to correctly choose their destination whether the signs were co-located or not.DiscussionFor the particular configuration of signs tested there is no evidence that co-location negatively impacts driving performance. However, there may be some implications for travel speed and the manner in which the emergency event is responded to. Future work should confirm the findings on real roads. These findings provided support for sign co-location as a practical and safe option for displaying multiple road signs in a confined area. 相似文献
