This study focused on novice drivers. Novice drivers get involved in more traffic accidents than the other drivers because of less driving experience. The aim of this study is to investigate the relationship between driving confidence levels and speeding, drunken driving, and traffic accidents. 192 drivers responded driving confidence levels questionnaire and driving experience items. 'Circumstance Insensibility', 'Unsafe Driving', 'Incautious Driving', and 'Self-efficacy of Driving' had significant relations with speeding in novice divers group. Especially, 'Circumstance Insensibility' showed a significant relation with speeding, drunken driving and traffic accidents. In the result of path analysis, driving confidence levels explained 22% of the speeding, 12% of the drunken driving and 21% of the traffic accidents in novice drivers group. 'Circumstance Insensibility' was most effective for traffic accidents of novice drivers. We verified that 'Self-efficacy of Driving' affects on traffic accidents via speeding.

This driving simulation study examined relative differences in driving anger as the functions of drivers' gender and driving experiences, and actor-observer perspectives when they were exposed in two anger-provoking driving scenarios(cutting-in and sudden stop). The results showed the followings. First, neither drivers' gender nor driving experience, when they were considered independently of the driving situation types and actor-observer perspectives, yielded significant difference in driving anger. Second, actor-observer effect on driving anger was observed only in the cutting-in condition where other driver's intension was emphasized. Third, the female drivers of low driving experience tended to show the strongest tendency of actor-observer bias in the cutting-in condition. These results suggested that the levels of driving anger as the functions of drivers' gender and driving experience can be differed by types of driving situation as well as perspectives of drivers' interpreting the situations.

The purpose of this research is to study the relation between the change of driver's driving confidence level in the age categories and driving behavior. To survey the driving confidence level, we used the 'Driving Confidence Scale' questionnaire and surveyed the drive career, mileage, driving days, violation of traffic regulation (drunk driving, overspeed), traffic accident experience (assaulter, sufferer) together. The subjects of investigation were from 19-year-old to 80-year-old and 1,055 persons were participated in the research totally. To examinethe structure of driving confidence level, we executed the factor analysis. We compared the driving confidence level in the age categories (under 29-year-old, 30~39, 40~49, 50~64, over 65-year-old) and studied the relation between driving confidence level and driving behavior. Driving confidence level was composed of 4 factors such as 'insensibility to situation', 'unsafe driving', 'careless concentration' and 'self-efficacy of driving', and there was decreasing tendency for driving confidence level and overall driving behavior according to increasing age. Driving confidence level had the interrelation with age range, assaulting accident, suffered accident, driving period, drunk driving, overspeed, driving career and so on. We examined the difference of driving confidence level and driving behavior by dividing the participated drivers' groups into the traffic accident experienced group, drunk driving group and overspeed driving group, and there was a significant difference on driving confidence level and driving behavior between the group who had not experienced the violation of traffic regulation or traffic accident and another group who had experienced the violation of traffic regulation or traffic accident.

본 논문에서는 비상운전 상황하에서 표출되는 운전원들의 직무전략 및 인지적인 특성을 도출하기 위해 운전원 교육 프로그램을 대상으로 운전원들의 직무특성을 분석하였다. 운전원들의 직무특성을 인지과정의 개입 정도에 따라 크게 Macro와 Micro로 구분하여 이들 직무특성을 잘 대변해 줄 수 있는 비상운전 시나리오를 개발하였다. 시뮬레이터를 통해 개발 시나리오에 따른 운전원들의 비상운전절차 수행과정을 비디오로 기록, 운전원들의 행동과 대화내용을 전산 분석하여 직무특성을 도출하였다.

The purpose of the present driving simulation study was to investigate the effects of fatigue induced both by sleep deprivation and time-on-task on driver's driving performance. The results are as followings. First, although the drivers in almost every experimental conditions showed faster driving speed than that was required, the drivers in the sleep-deprivation and over 1-hour time-on-task condition drove slower than the target speed. Second, the drivers in the sleep-deprivation and over 1-hour time-on-task condition crossed the lane less frequently than those in the other conditions, they weaved more in the lane. Third, as the drivers became more fatigued both by sleep deprivation and continuous driving, they reported higher fatigue scores in the subjective fatigue ratings. The results suggested that although the drivers might adapt a compensative driving strategies when they were fatigued, their driving performances were indeed impaired, in general.

This study focused on driver's carefulness and researched the relationship between driving confidence and driving behaviour in elderly and young drivers. In order to evaluate the driving confidence level, 'Driving Confidence Scale' was developed. 175 of young drivers(younger than 25) and 150 of elderly drivers(older than 65) conducted Driving Confidence Scale. They answered their driving patterns; driving history, annual mileage, the frequency of committing traffic violation, and experience of accident within 5 years. Elderly driver's data was collected by face to face interview. The factors of driving confidence were analyzed and the driving confidence level of young and elderly drivers was compared. Driving Confidence was consisted of 4 factors; environment of traffic condition, safe driving, driving ability, attention. Elderly driver's confidence was lower than young driver's. Elderly drivers in high driving confidence group, showed longer driving history and they were tend to commit violations more frequently than elerly drivers in low driving confidence group. Young drivers, whose driving confidence level was high answered more driving history, annual mileage, the frequency of committing traffic violation and experience of accident within 5 years.

This study is to investigate the effects of driving anger and traffic congestion on drivers' behaviors. Driving anger is the propensity to become angry while driving, and people differ in the tendency to get angry when encountering frustration and provocation on the road. Individual differences of the propensity contribute to anger on the road and aggressive driving leading traffic vaiolations and accidents. In the experiment three traffic conditions (an open road condition, a bumper-to-bumper traffic condition and a being stuck behind a slower driver condition) were simulated and driving behaviors were collected with RTSA-DS(Road Traffic Safety Authority-Driving Simulator). The results were as follows: Most of high anger drives drove at higher speeds in an open road condition, and in the bumper-to-bumper condition they drove faster and had an higher crash rate, which suggests they did aggressive driving, and risky and unsafe behaviors.

본 연구는 발전 기술이 다양한 우리나라 원자력 발전소들 사이의 운전 경험에 대한 정보가 원자력 발전소의 운전 성과에 미치는 효과를 실증적으로 분석하는 것을 목적으로 하였다. 기존의 원자력 발전의 학습 효과 분석은 주로 단일 발전소를 대상으로 수행되었다. 그러나 어떤 발전소의 운전 경험이 운전 성과에 미치는 효과는 그 발전소에만 국한되는 것이 아니고 다른 발전소에도 영향을 줄 수 있으므로 발전소들 사이의 운전 경험에 대한 정보의 공유에 대한 분석이 요구된다. 그런데 모든 발전소의 운전 경험이 동일한 가치를 가지고 있다고 볼 수는 없다. 동일 부지와 동질적 발전 기술을 가진 발전소들 사이에는 운전 경험의 운전학습효과가 클 것이지만 다른 부지와 이질적 발전 기술의 발전소들 사이에는 운전 경험에 관한 정보의 공유 비용이 높을 것으로 기대된다. 본 연구의 실증 분석 결과, 동질적 기술을 가지고 있는 발전소들 사이의 운전 정보의 공유가 대체적으로 더 활발한 것으로 분석되었으며 동일 부지에 있는 발전소들의 운전 경험이 운전 성과 향상에 미치는 효과가 큼을 알 수 있다. 이러한 실증 분석 결과는 예상과 일치하는 것으로 기존의 다양한 원자력 발전 기술의 도입이 발전소의 운전 성과 측면에서는 비효율적이었음을 지적하는 것이다.

차세대원전을 위한 새로운 운전여유도 평가체제를 정립하였다. 본 연구에서 개발된 운전여유도 평가체제는 노심감시 및 보호체제는 그대로 유지하되 부하추종운전시 운전여유도를 만족하는 운전허용범위를 P-ASI Diagram으로 나타내는 것이다. 새로운 운전여유도 평가 방법을 사용하여 Mode K 기법에 의한 차세대원전의 일일 부하추종운전에 대한 운전여유도 평가를 수행하였으며, 운전여유도를 만족하는 범위를 P-ASI Diagram으로 나타내었다. 본 연구에서 도출한 운전여유도와 ASI의 관계를 쉽게 파악할 수 있는 P-ASI Diagram이 COLSS와 병행된다면 운전유연성 증진 뿐만아니라 운전원의 입장에서도 더욱 용이한 부하추종운전을 수행할 수 있을 것으로 판단된다.
