PURPOSES : This study deals with first traffic violations occurred by novice drivers, which may be associated with traffic accidents. The objective of this study is to identify what kinds of drivers' characteristics influence on duration till the first traffic violation. METHODS : For the study, Survival Analysis and Cox proportional hazard model, that are usually used in the medical field, were employed. Survival Analysis was conducted to investigate whether there exist differences in survival duration by each covariate, whereas Cox proportional hazard model was used to identify significant factors that affect survival duration till novice drivers violate traffic regulations for the first time after getting a driver license. RESULTS : The results of Survival Analysis indicate that female, age (less than 21), low-frequency examinee of written exam, and non-crash involved drivers have longer duration till the first violation compared to male, greater than 21 years old, high-frequency examinee of written exam, and crash involved drivers, respectively. For the Cox proportional hazard model, license class 1 acquisitor was found to increase the survival duration till the first traffic violation was made, while male, age of 21-24, age of 25-34, age of 45-54, and crash involved drivers were more likely to reduce the survival duration. CONCLUSIONS : Absolutely, traffic violation is closely related to traffic accidents and all of the drivers should keep the traffic regulations to enhance highway safety. The results of this study might provide some insights to construct safe road environments by controlling the factors that reduce the traffic violation duration of novice drivers.

Background: Working conditions and psychosocial work factors have acquired an important role explaining the well-being and performance of professional drivers, including those working in the field of public transport. This study aimed to examine the association between job strain and the operational performance of public transport drivers and to compare the expositions with psychosocial risk at work of three different types of transport workers: taxi drivers, city bus drivers, and interurban bus drivers. Method: A sample of 780 professional drivers was drawn from three transport companies in Bogota (Colombia). The participants answered the Job Content Questionnaire and a set of sociodemographic and driving performance questions, including age, professional driving experience, work schedules, and accidents and penalties suffered in the last 2 years. Results: Analyses showed significant associations between measures of socio-labor variables and key performance indicators such road traffic accidents and penalties. Furthermore, multiple linear regression analysis contributed to explain significantly suffered accidents from key variables of the Job Demand-Control model, essentially from job strain. In addition, throughout post-hoc analyses, significant differences were found in terms of perceived social support, job strain, and job insecurity. Conclusion: Work stress is an issue that compromises the safety of professional drivers. This research provides evidence supporting a significant effect of job strain on the professional driver's performance. Moreover, the statistically significant differences between taxi drivers, city bus drivers, and interurban bus drivers in their expositions to work-related stress suggest the need for tailored occupational safety interventions on each occupational group.

In this study, the causes of human error were identified through the survey of the drivers of the three organizations: Seoul Metro, Seoul Metropolitan Rapid Transit Corporation, and Korail. It was started with the aim of finding and eliciting causes in various directions including human factors, job factors, and environmental factors. The Cronbach alpha value was 0.95 for the reliability significance of the stress-induced factors in the operational area. The significance probability for organisational factors was shown to be 0.82, and the significance of the sub-accident experience and the driving skill factors in operation was 0.81 In addition, the analysis results showed that stress-induced in the field of driving is higher than the human factors in the reliability analysis. The results of the analysis confirmed that the reliability of the organizational and operational stress-induced factors was higher than other causes. In order to reduce urban railroad accidents, this paper suggests a method for operating safe urban railroad through the minimization human errors.

Traffic accidents occur due to complex influences of transportation companies, drivers, and road environment. This study found that education and surroundings for transportation companies, driving habits of drivers, and road safety facilities and accessory facilities were main factors that affected strongly traffic accidents. Also, it found that driving habits of drivers could affect accidents heavily more than two other factors. Road safety and accessory facilities were analysed that they affected traffic accidents independently with transportation companies and their own drivers. Therefore, in order to achieve a traffic accident prevention as our main target, those companies need to produce atmosphere that their own drivers can have safety awareness, and related institutions for the above target should run parallel with policy assistance and strict traffic enforcement. In the end, this study suggests that transportation companies should secure manpower wholly being charged with traffic safety and financial resources investing in it.

교차로는 일반 도로와 달리 서로 다른 기하구조 및 교통운영을 가진 도로가 결합되는 지점으로 매우 복잡한 도로 환경적 요인을 내포하고 있다. 특히, 교차로 접근도로에서 진입하는 차량 간의 상충과 정지 신호시 급정지, 녹색 등화시 급출발 등 다양한 주행패턴의 변화로 인해 교통사고는 지속적으로 발생되며, 교통사고의 주요 발생원인은 인적요인으로 알려져 있다. 이에 본 연구에서는 교차로 영향권 내에서의 운전자 행동에 영향을 주는 요인을 도출하기 위해 최첨단 계측장비를 활용한 뇌파, 시각, 주행속도 등의 생리적 반응을 측정하였다. 개별 교차로의 집중도 뇌파는 보조 간선도로에 비해서 주 간선도로, 사고다발 교차로에서 피실험자의 생체적 반응 뇌파가 높게 출현되고 있음을 규명하였다. 또한, 사고다발 교차로에 서 운전자의 시각활동은 넓게 분포함으로써 주변 차량으로부터의 주의운전을 강화하고 있는 것으로 분석되었다. 또한, 운전자 부하를 유발하는 주요 요인으로 감속과 가속, 주변 차량의 차로변경, 주행속도 변화 등의 요인이 운전자 부하에 직접적인 요인으로 나타나 교차로의 교통사고의 발생원인과 매우 밀접한 관계가 있음을 규명하였다. 본 연구의 결과는 향후 운전자의 생체반응을 고려한 교차로의 안전성 평가를 위한 기초자료로 할용이 가능할 것으로 판단된다.

Recommendations for older driver-friendly automobile interior design have been determined by taking into account older people's physical and cognitive characteristics. Twenty three older people (aged from 54 to 78) and five younger people (from 20 to 29) performed several tasks in actual driving conditions, in which their reaction times and performance errors were recorded. Some design factors were found to be related to older drivers' visibility and controllability. Several design recommendations were proposed in terms of cluster color and font, display location, and HVAC control type. Proposed recommendations are expected to satisfy a wider range of older drivers as these will facilitate automobile interior designs which are fitter to older drivers' visual, cognitive, and manual capabilities.

자율주행자동차의 도입은 자동차의 산업생태계 변화뿐만 아니라 사회적, 문화적, 경제적 변화를 가져올 것이다. 사회적 수용성은 자율주행자동차 상용화가 성공하기 위한 중요한 영향 요인 중 하나이다. 본 연구는 수요자 관점에서 자율주행자동차의 수용에 영향을 주는 요인들이 무엇인지 분석하였다. 본 연구에서는 운전자의 개입 여부에 따라 부분자율주행자동차(PAV)와 완전자율주행자동차(FAV)로 정의하였다. 설문은 운전자뿐만 아니라 비운전자도 포함하여 20세 이상을 대상으로 수행되었다. 그 결과 PAV와 FAV 수용에 영향을 미치는 요인들은 다르게 나타났다. PAV의 경우 운전자와 직접적인 관련이 있는 요인들이 수용성에 영향을 미쳤고, FAV의 경우 외부 환경 요인들이 자율주행자동차의 수용에 영향을 미치는 것으로 나타났다. 이러한 결과는 PAV와 FAV의 수용 확산을 위해서는 서로 다른 전략이 필요하다는 것을 보여주었다.
