According to the Korean Traffic Accident Analysis System (TAAS), more than 200,000 traffic accidents occur every year. Also, the statistics including auto insurance companies data show 1.3 million traffic accidents. In the case of TAAS, the types of traffic accidents are simply divided into four; frontal collision, side collision, rear collision, and rollover. However, more detailed information is needed to assess for advanced driver assist systems at intersections. For example, directional information is needed, such as whether the vehicle in the car accident way in a straight or a left turn, etc. This study intends to redefine the type of accident with the more clear driving direction and path by referring to the Negligence standards used in automobile insurance accidents. The standards largely divide five categories of car-to-car/motorcycle /pedestrian/cyclist, and highway, and the each category is classified into dozens of types by status of the traffic signal, conflict situations. In order to present more various accident types for auto insurance accidents, the standards are reclassified driving direction and path of vehicles from crash situations. In results, the car-to-car accidents are classified into 33 accident types, car-to-pedestrian accidents have 19 accident types, car-to-motorcycle accidents have 38 accident types, and car-to-cyclist accidents are derived into 26 types.

COVID-19 여파로 인한 비대면 서비스와 가정 재정 불안정성의 증가로 이륜차 보험사기 발생이 예상되고 있다. 이와 함께 보험사기 수법도 갈수록 교묘해지고 있다. 하지만 비대면 배달 수요와 연관된 이륜차 교통사고와 보험사기 적발 모형 관련 연구는 매우 미흡한 실정이다. 이에 본 연구는 보험사기의 표본 편중문제를 해결하기 위해 균형 랜덤포레스트 알고리즘을 이용하고 보험사기 조사 전문가의 정성적인 판단 기준을 반영한 변수를 모델에 포함하여 적용성을 향상시키며 적발력 높은 이륜차 보험사기 모형을 개발하고자 한다. 보험사기 적발 모형 개발 결과, 기존의 비균형 랜덤 포레스트 모형에 비해 균형 랜덤 포레스트가 보험 사기혐의자를 분류하는 데 있어 통계적으로 우수한 점을 확인할 수 있었다. 특히, 총 26개의 변수를 토대로 탐색적 변수 조합을 적용한 모형의 예측 성능이 가장 높았지만 일부 변수만을 사용한 확인적 모형의 예측 성능도 크게 떨어지지 않은 와중에, 정성적인 보험사기 전문가가 선정한 변수만을 사용한 확인적 모형은 예측력이 떨어지는 것을 확인하였다. 또한, 총 26개의 변수 중 운전자 성별, 연령, 운전자 피보험자 일치 여부, 미수선 청구금액, 대인보험금 등이 중요한 변수로 확인되어 이를 활용해 이륜차 보험사기 혐의자 선별을 위한 적극적인 대처가 필요해 보인다.

In order to improve occupant protection in frontal crash, the IIHS introduced a small overlap frontal crash test in 2012. When the front corner of a car collides with another car or object, such as utility pole the test replicated the sequence of events. Because occupants move simultaneously forward and toward the side of the vehicle this test is challenging for some airbag and safety belt designs. In the small overlap frontal test, a car travels at 64 km/h toward a rigid barrier. A hybrid III dummy is positioned in the driver seat. 25% of the total width of the car strikes the barrier on the driver side. After review of small overlap frontal test protocol and overall rating, six run-throughs were performed according to the original test method.

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.

The Korean government announced its goal of commercializing autonomous vehicle by year 2020. With such changes, it is expecting to decrease car accident mortality by half. To commercialize autonomous car, not only worries on safety of autonomous vehicle has to be solved but at the same time, institutional system has to be clear to distinguish legal responsibilities in case of accident. This paper will present the legal improvement direction of the introduction of autonomous vehicles as follows. First, it is necessary to re-establish concept of 'driver' institutionally. Second, it is appropriate to focus on Level 3 autonomous vehicle which is about to be commercialized in year 2020 and organize legal responsibility. Third, we should have a clear understanding on how level 3 autonomous vehicle will be commercialized in the future. Fourth, it is necessary to revise The Traffic Law, Act on Special Cases concerning the Settlement of Traffic Accident, and Automobile Accident Compensation Security Law in line with level 3 autonomous vehicle. Fifth, it is necessary to review present car insurance system. Sixth, present Product Liability Law is limited to movable products (Article 2), however, it is necessary to include intangible product which is software. Seventh, we should review on making special law related to autonomous car including civil, criminal, administrative, and insurance perspectives.

This study deals with characteristics and risk of a PM based on user survey result, road driving test and data analysis of PM accident. Text mining method is applied to extract PM accident data from Big Data, which are claim data of private insurance company. Road driving test and survey on safety, convenience, noise, overtake ability, steering ability, and climbing ability of PM are performed to evaluate user's safety and convenience considering domestic road condition. As the result of claim data analysis, annual average increase rate of PM accident is 47.4% and average compensation of personal mobility is higher than that of bicycle by maximum 1.5 times. 79.8% of PM accident is self-caused accident due to unskilled driving and age-specific diagnosis rate of driver over 60 is higher than that of under 60. Diagnosis rate of over 60 at lower limb, foot, rib and spine is especially higher than that of under 60. As the result of road driving test and user survey, satisfaction level on safety and convenience of PM is evaluated as close to that of bicycle and satisfaction level of PM is increased after boarding. Overtake ability, steering ability, and climbing ability of PM are evaluated as same or better than that of bicycle but warning equipment to pedestrian or bike such as horn is required because noise level of PM during driving is too low. Finally, user survey result shows that bicycle road is suitable for PM and safety standard, advance-education and insurance are required for PM. It is suggested that drivers' license for PM can be replaced by advance-education. Results of this study can be used to prepare safety measures and legal basis for PM operation.

This paper describes effectiveness of accident reduction on vehicles equipped with AEB using accident data occurring in Korea. During the statistical period, we used the number of vehicles which are covered by auto insurance and the number of accidents. To maximize the reduction effect of accidents caused by the driver's carelessness, the analysis was limited to Physical Damage Coverage that covers the cost of repairing or replacing the damaged vehicle caused by the driver's fault. Due to Personal Information Protection Law, it was not capable of comparing the same vehicle using Vehicle Identification Number in this study. Instead of that, we used it as a similar vehicle, so there are limits to the comparison and analysis results. As a result of this study, we have found that the effect of reducing accidents was different depending on the vehicle class, but it was generally concluded that the number of accidents decreased when the vehicle was equipped with an AEB system. Domestic research on the AEB effect of reducing accidents is not active yet. Therefore, it is absolutely essential to analyze the effects according to various conditions such as driver's age, occupation and gender as well as expanding the study models in the future.

Recently a traffic accident of heavy duty vehicles under the mandatory installation of ADAS (Advanced Driver Assistance System) is often reported in the media. Heavy duty vehicle accidents are normally occurring a high number of passenger's injury. According to report of Insurance Institute for Highway Safety, FCW (Forward Collision Warning) and AEB (Automatic Emergency Braking) were associated with a statistically significant 12% reduction in the rate of police-reportable crashes per vehicle miles traveled, and a significant 41% reduction in the rear-end crash rate of large trucks. Also many countries around the world, including Korea, are studying the effects of ADAS installation on accident reduction. Traffic accident statistics of passenger vehicle for business purpose in TMACS (Traffic safety information Management Complex System in Korea) tends to remarkably reduce the number of deaths due to the accident (2017(211), 2018(170), 2019(139)), but the number of traffic accidents (2017(8,939), 2018(9,181), 2019(10,095)) increases. In this paper, it is introduced a traffic accident case that could lead to high injury traffic accidents by being equipped with AEB in a bus. AEB reduces accidents and damage in general but malfunction of AEB could occur severe accident. Therefore, proper education is required to use AEB system, simply instead of focusing on developing and installing AEB to prevent traffic accidents. Traffic accident of AEB equipped vehicle may arise a new dispute between a driver's fault and vehicle defect. It is highly recommended to regulate an advanced event data recorder system.

The purpose of this empirical study is to test hypotheses in order to identify the cost drivers that drive indirect costs in general hospitals in Korea. In various cases' studies, it has been suggested that overhead costs are driven by volume and complexity variables, how they are structurally related and how the cost impacts of these variables can be A unique feature of the research is the treatment of complexity as an endogenous variable. It is hypothesized that level of hospital complexity in terms of the number of services provided(i.e., “breath" complexity) and the intensity of individual estimated in practice. overhead services(ie., “depth" complexity) are simultaneous determined with the level of costs needed to support the complexity. Data used in this study were obtained from the Database of Korean Health Industry Development Institute, Health Insurance Review Agency and analyzed using simultaneous equation model, path model. The results found those volume and complexity variables are all statistically signi-ficance drivers of general hospital overhead costs. This study has documented that the level of service complexity is a significant determinant of hospital overhead costs, caution should be exercised in interpreting this as supportive of the cost accounting procedures associated with ABC. with ABC.
