도로교통사고의 관리는 경찰서의 주요한 업무중의 하나이다. 이를 위해 각 관할경찰서는 교통사고발생 시 사고기록을 하며 기록된 자료는 통계적 분석의 근거로 사용되게 된다. 대부분의 사고통계분석 결과는 거시적인 수준에서의 효율적인 교통관리계획과 교통안전정책을 확립하는데 적용되어 왔다. 본 연구에서는 각 관할경찰서가 지역적 특성에 따른 구체적인 교통사고 예방정책을 시행할 수 있도록 품질기능전개(QFD)를 적용하였다. 사고다발지점을 찾기 위해 군집분석을 사용하였으며, QFD의 입력자료로 사용하기 위하여 각 관할지역별로 다양한 형태의 도로교통사고를 위한 포아손 회귀분석을 하였다. 본 연구의 결과는 지역마다 특징적으로 발생하는 다양한 형태의 도로교통사고 감소에 기여할 것으로 기대된다.

PURPOSES : The effects on traffic accidents change with the changing environment. Accordingly, this study analyzes the characteristics of traffic accidents based on the personal characteristics (gender and age) of drivers, and those of 25 autonomous districts in Seoul, and suggests improvements. METHODS : Based on data pertaining to traffic accidents in Seoul, the analysis of accident characteristics was conducted by categorizing the types of traffic accidents according to the drivers' gender and age, and characteristics of 25 autonomous districts in Seoul. Further, for statistical verification, the SPSS software was used to derive influence variables through a multinomial logistic regression analysis, and a method for reducing traffic accidents was proposed. RESULTS : Analysis results show that males tend to be more involved in speed-related accidents and females in low-experience driving-related accidents such as those during parking and alleyway driving. In addition, variables such as age, automobile type, district, and day of the week are found to influence accident types. CONCLUSIONS : This study analyzed the accident characteristics based on personal and city characteristics to reflect the sociological characteristics that influence traffic accidents. The number of traffic accidents in Korea could be decreased drastically by implementing the results of this study in customized safety education and traffic maps.

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.

This study aims to develop the traffic accident models by circular intersection type using count data model. The number of accident, the number of fatal and injured persons(FSI), and EPDO are calculated from the traffic accident data of TAAS. The circular intersection accident models are developed through Poisson and negative binomial regression analysis. The main results of this study are as follows. First, the null hypotheses that there are differences in the number of traffic accidents, FSI and EPDO by type of circular intersections are rejected. Second, the scale of intersection(median, large), number of approach road, mean width and length of exit road, area of the circulating roadway and central island are selected as factors influencing the number of traffic accidents, FSI and EPDO in rotary. Third, the scale of intersection(median), guide signs(limited speed, direction, roundabout), number of approach road, entry angle, area of the intersection and central island are adopted as factors influencing the number of traffic accidents, FSI and EPDO in roundabout. Finally, transferring from rotary to roundabout could be expected to make the accident decrease.

Objective: Objective of this study is to provide characteristics of injury frequency and severity by driving condition in large truck-related traffic collisions. Background: Traffic accidents involving large trucks draw a lot of attention in accident prevention and management policies since they bring about severe human and financial damages. Method: In order to identify the major risk factors of accidents by driving condition, 255 recognized traffic accidents by large truck drivers were analyzed in terms of time of the day, road type, and shape of the road. Results: The driving conditions in the results are represented by the following form of combination, "Road Type (Non-expressway or Express) - Shape of Roads (Straight, Curved, Downhill, or Intersection) - Time of Accidents (Day or Night)". In the analysis of injury frequency, Non-expressway-Straight-Day condition was the most frequent one. Meanwhile, Expressway-Curved-Day, Non-expressway-Curved-Night and Non-expressway-Intersection-Night were evaluated as high level in view of injury severity. Also, Expressway-Straight-Night is the driving condition that is the highest in risk among the conditions that have to be managed as grade "High". Non-expressway-Straight-Night, Non-expressway-Downhill-Day, and Non-expressway-Curved-Day are also categorized as grade "High". Conclusion and Application: Safety managers in the fields require basic information on accident prevention that can be easily understood. The research findings will serve as a practical guideline for establishing preventive measures for traffic accidents.

서울시의 생활도로내 비신호교차로는 2008년 총 41,702건의 교통사고 가운데 3,753건(9%)로 교통사고 발생율은 높지 않은 실정이나, 교통 기초부분의 불합리하고 미비한 제도 및 시설 운영으로 인하여 사고의 잠재성이 더욱 높다고 볼 수 있다. 특히 생활도로내 비신호교차로의 경우는 신호교차로에 비해 안전대책이 미흡한 실정이며, 교통사고의 분석 및 영향요인 모형에 관한 국내 연구가 매우 부족한 상황이다. 또한 외국과는 달리 우리나라의 경우 비신호교차로 운영의 통행우선권 개념이 설정되어 있지 않기 때문에 생활도로내 비신호교차로의 안전성 향상을 위한 연구와 안전대책이 시급하다. 따라서 본 연구에서는 생활도로내 비신호 교차로 교통사고예측모형 구축 과정 중 일반적으로 제한된 변수의 선정 및 모형의 구축에만 주로 초점이 맞추어진 기존 방법론의 문제점을 개선하고, 자료수집 및 수집과정에서 발생하는 자료의 불확실한 상태를 인정하면서 자료의 불확실성을 최소화하여 이용할 수 있는 방법론을 개발하는데 연구의 주안점을 두었으며, 사전에 위험요소들을 처리하여 적절한 교통안전정책을 세우도록 방향을 제시하고, 생활도로내 비신호 교차로의 안전성을 높이려는데 목적이 있다.

This study intends to present a traffic node-based and link-based accident prediction models using XGBoost which is very excellent in performance among machine learning models, and to develop those models with sustainability and scalability. Also, we intend to present those models which predict the number of annual traffic accidents based on road types, weather conditions, and traffic information using XGBoost. To this end, data sets were constructed by collecting and preprocessing traffic accident information, road information, weather information, and traffic information. The SHAP method was used to identify the variables affecting the number of traffic accidents. The five main variables of the traffic node-based accident prediction model were snow cover, precipitation, the number of entering lanes and connected links, and slow speed. Otherwise, those of the traffic link-based accident prediction model were snow cover, precipitation, the number of lanes, road length, and slow speed. As the evaluation results of those models, the RMSE values of those models were each 0.2035 and 0.2107. In this study, only data from Sejong City were used to our models, but ours can be applied to all regions where traffic nodes and links are constructed. Therefore, our prediction models can be extended to a wider range.

Exceptive clause of ambulance stated in Road Traffic Laws of ambulance car accidents is not properly applied and emergency staffs who transfer over 85% of emergency cases are to be forced to start out to the emergency field with unstable conditions which they may be punished on the criminal and civil laws. Hereby this study makes the following suggestions to activate the duties of transferring emergency cases by emergency staffs, promote their morale and diminish the victim of emergency staffs due to traffic accidents. 1) It is prescribed that ambulance car drivers should be protected legally by applying the exceptive clauses thoroughly regulated in special case clauses because ambulance cars are used for the purpose of saving the human life. 2) On the traffic accidents occurred during the transfer of emergency cases, the special insurance system is created for treating the ambulance car accidents, not to bind the emergency staff's mistake to traffic law and the victims are compensated by the nation on the basis of insurance system and emergency staffs have the systematic security. 3) On the road over six lanes, emergency lane is set on the center and ambulance car should be used as the exclusive lane. 4) Ambulance car drivers must have the habit of transferring emergency cases rapidly within the range of legal operation.
