  • This study was conducted to examine the usage effects of an augmented reality head-up display (AR-HUD) system on the risk perception and psychological changes of drivers. To do so, we conducted an experiment to collect the driver response times for vehicles and pedestrians as their risk perception behavior, and used a driving behavior determinants questionnaire consisting of Problem Evading, Benefits/Sensation Seeking, Anti-Personal Anxiety, Anti-Personal Angry, and Aggression factors for collecting the psychological characteristics of the drivers. Thirty drivers were randomly assigned into an in-vehicle AR-HUD using group and a control group. As a result, the Anti-Personal Anxiety and Anti-Personal Angry factors were negatively correlated with the response time for the control group. In contrast, these results were not shown for the in-vehicle AR-HUD system using group. These results indicate that the in-vehicle AR-HUD system may partially induce a relaxation of tension or stress for drivers with a high level of interpersonal anxiety. Therefore, the in-vehicle AR-HUD system might contribute to not only the visual safety driving behaviors of drivers, but also to their psychological driving safety with specific characteristics.

  • Objectives: The purpose of this study was to evaluate the level of workplace violence experienced by taxi drivers and identify the affected factors. Methods: Two hundred twelve taxi drivers were investigated for general characteristics and workplace violence was evaluated using K_WVSⓇ13. The data was collected from July to October 2020 through questionnaires. It was analyzed using t-test and ANOVA with SPSS WIN23.0. Results: Most of the taxi drivers were elderly and suffered from long hours of labor and low wages. After evaluating four sub-factors of workplace violence, 'psychological and sexual violence from customers', 'psychological and sexual violence from customers, supervisors, and coworkers' and 'physical assault from customers/supervisors/coworkers' were judged as risks. For 'psychological and sexual violence from customers, supervisors, and coworkers', the mean score by age was significantly higher for workers in their 70s or older and those with 30 years of experience compared to other age groups. In the case of 'psychological and sexual violence from customers', sales taxis were significantly higher than private taxis. Conclusions: It is necessary to develop a workplace violence prevention program suitable for the characteristics of taxi drivers in order to manage their physical and mental health. When establishing such a program, business type, age, and experience must be considered.

  • According to statistics, drunk drivers who repeatedly violate the DUI (Driving under influence) regulation have been continuously increased, and now the habitual drunk drivers become a societal problem. Employing a confirmative factorial analysis of structural equation model to analysis psychological characteristics of habitual drunk drivers and also seek countermeasures, this study identify the difference among three different groups of drivers: 1) sober drivers, 2) drivers with a DUI violation record, and 3) drivers with more than two records. The results of this study are as follows: First, remedies and educational contents to rectify drunk drivers can be differentiated according to their drunk driving records. Second, using defense mechanism (e.g., rationalization, projection, sublimation), drunk driving psychology (such e.g., sense of guilt, shame, embarrassment) and self-esteem (e.g., affirmation, denial) as theory variables, a Structural Equation is constructed to represent Psychological Characteristics of drunk driving according to records on drunk driving. Third, as a result of analysis of the Psychological Characteristics Model, measures for prevention and reduction of drunk driving suitable for the characteristics of respective group are also suggested. Forth, drunk driving measures based on drinking individuality are complemented by concurrence analysis on records of drunk driving records and National Alcoholism Screening Test (NAST) score. Also, two or more times recorded drunk drivers are classified as inveterate drunk drivers.

  • Recently, there is a growing interest in promoting safe and convenient roadway and traffic conditions for elderly drivers. This paper analyzed the driving characteristics, self recognition, and any inconvenience of elderly drivers over age 65 through an extensive survey, and drew some action plans to improve the driving conditions for elderly drivers. Survey results showed that the major trip purposes of the elderly driver were found to be commuting(50%) and business(33%), and this pattern was similar to the general drivers. The elderly drivers are interested in "safety", but "brand recognition" was the more important factor for the general drivers in the process of vehicle selection. The elderly drivers had no technical skill difference in driving as compared to the general drivers, but they fully recognized the physical deterioration such as reaction time and sight distance. In addition, the elderly drivers had a tendency to feel psychological contraction as to high workload driving conditions, thus it was necessary to make safe driving conditions by improving the design elements of traffic control devices on the roadways including visibility.

  • As majority of the traffic accidents in intersections is caused by human factor, a close examination is required on its contributing factors through measuring the psychological and physiological response according to the driving characteristics of the drivers and the road conditions. In this study, for the safety evaluation of individual intersection considering human factors of the drivers, electroencephalography reaction was measured utilizing cutting-edge measuring equipment and survey on drivers' cognitive characteristics in ordinary times and while driving test was conducted. The relationship between the electroencephalography response when approaching the intersection and cognitive evaluation survey data in driving test was clarified, and individual intersection safety evaluation model was built considering cognitive evaluation factor and the reaction of a bio-response electroencephalography data. As a result, I could find out that cognitive evaluation was made through the reaction of a bio-response (Electroencephalography) process because electroencephalography reaction of a bio-response showed differently by the physical characteristics of the intersection and cognitive evaluation had a difference.

  • Tunnel sections on the highway are different from rest of sections on the highway in terms of velocity, the number of passing cars, and vehicle density which, in particular, affect drivers' behavior before and after drivers pass through the tunnel. However, literature review reveals that former studies are too focused on quantitative indicator to consider qualitative aspects. Therefore, this paper conducts survey questionnaire and IPA (Importance Performance Analysis) to find out qualitative improvements on velocity drop on the tunnel sections. The results show as follows: First, drivers require improvements of tunnel form (length and curved form inside tunnel) which is derived from long distance tunnel. Second, experts primarily ask for amendment of geometric characteristics. With comparison of requirements of both drivers and experts, there are many differences in length of tunnel and form of curved tunnel. This also presents that drivers don't satisfy with both length of tunnel and form of curved tunnel that are provided as a part of highway design factors.

  • The objectives of the present research are twofold. First, this research aims to compare the effect of trait characteristics(sensation seeking, social resistance and type-A behavior) with that of driving specific characteristics(driving anger and type-A driving) on problematic driving behavior. Second, the role of life stress as a mediator in the relationships between general trait characteristics and traffic safety index was examined. 1158 licensed commercial vehicle drivers were surveyed and their accident-related records were obtained in this research. Results showed that driving specific characteristics were significant indicators of traffic safety and life stress mediated the relationships between general trait characteristics and traffic safety index. These findings implicate that understanding drivers' driving specific characteristics and their levels of life stress is important to reduce problematic driving behaviors and enhance traffic safety.

  • This paper investigated habitual drunk drivers' characteristics by grouping them by the number of DUI records, and customized countermeasures for each group. Theoretical models to accommodate underlying causes for drunk driving, which adopted the form of a path analysis, were developed based on psychological variables. According to the psychological paths to drunk driving, each group showed different defense mechanisms and different senses of guilty, shame and embarrassment. This provided a rationale for differentiating countermeasures for each group. Habitual drunk drivers were found to have a strong propensity of self-justification due to their defense mechanism. Thereby, it would be useless to simply discourage them from drinking and driving. Rather, more active measures such as locking devices, invalidation of driver license, and group counseling should be taken to stop habitual drunk driving. Furthermore, since habitual drunk drivers showed high projection propensity, it is necessary to force them to participate in a sensibility training program, which might entail the amendment of related laws or regulations.

Differential Effects of Subjective Evaluation for Attention and Situation Adaptability on Driving Mobility as a Function of Driver's Age: Moderating Effect of Motivation (연령대에 따른 주관적 주의능력과 외부환경 적응능력이 운전이동성에 미치는 영향에서의 차이: 동기특성의 조절효과)

  • This study investigated the differential effects of subjective evaluation for attention and situation adaptability, and motivation on driving mobility as a function of driver's age. The results can be summarized as followings. First, subjective capability evaluation tended to decrease as the drivers' age increased, and lower evaluation for situation adaptability seemed to be recognized earlier than attentional ability in middle-aged drivers. Second, although subjective evaluation for attentional ability predicted positively driving mobility of all age groups, but only subjective evaluation for situation adaptability predicted positively driving mobility of older drivers. Third, among motivational elements, BAS predicted positively driving mobility of young and middle-aged driviers, whereas BIS predicted positively driving mobility of older drivers. Finally, middle-aged drivers tended show increased driving mobility when their attentional ability score and BAS were high, whereas older drivers showed lowest level of driving mobility when their situation adaptability score and BIS were low. These results suggest importance of integrated consideration for drivers' subjective evaluation for attention and situation adaptability, and motivation to understand characteristics of driving mobility in different age groups.
