New Car Assessment Program(NCAP) provides consumers with vehicle safety information, primarily front and side crash rating results, and more recently rollover ratings, to aid consumers in their vehicle purchase decisions. NCAP is a system to improve driver and passenger safety by providing market incentives for vehicle manufacturers to voluntarily design their vehicles to better protect drivers and passengers in a crash and be less susceptible to rollover, rather than by regulatory directives. NCAP have been performed since 1999 in Korea by the government in order to reduce fatalities and injuries caused by traffic accidents. Although as the number of vehicles models increases, more vehicle models are required to be test and NCAP is evaluated as a valuable system for vehicle safety, the expansion of the system is slow. It looks like that the benefit of NCAP quantitatively was not verified. In this study, based on the idea that the benefit of the NCAP is defined as the decrease of traffic accident severity by improving vehicle safety, a methodology to analyze the effectiveness of NCAP quantitatively in terms of traffic safety was developed. According to the developed methodology, the reduced numbers of fatalities and injuries were 1.51 and 466 in 2005. 자동차 안전도평가제도는 제작사가 보다 안전한 자동차를 제작하도록 유도하기 위해 충돌시험 등을 통하여 자동차의 안전성을 평가하고, 그 결과를 소비자에게 공개하고 있다. 이것은 자동차 사고로 인한 사회적 손실을 감소시킬 수 있는 효과적인 자동차 안전정책 중의 하나로써, 우리나라는 1999년부터 건설교통부 주관으로 신차평가를 실시하고 있다. 현재 안전도평가 대상차종이 크게 증가하여 안전도평가 대상 차종의 확대가 필요한 시점임에도 불구하고, 현실은 그렇지 못한 실정인데, 그 이유로는 평가인력, 시설 및 비용 등 여러 가지가 있겠으나, 가장 근본적인 이유는 자동차 안전도평가제도의 효과를 정확하게 파악하지 못하기 때문인 것으로 판단된다. 이에 본 연구에서는 자동차 안전도평가제도를 통해 자동차제작사가 자동차의 안전도를 향상시킴으로써 교통사고 발생 시 사고의 심각도를 얼마나 줄여줄 수 있는지를 정량적으로 분석함으로써 자동차 안전도평가제도의 효과를 측정해 보고자 하였다. 안전도평가 항목 중 이용가능한 자료가 있는 정면충돌만을 대상으로 정면충돌로인한 사상자 수를 추정하고 안전도가 향상된 차종의 판매대수를 이용하여 자동차 안전도평가제도의 효과를 측정할 수 있는 방법을 개발하였다. 2005년도 자료를 이용하여 정면충돌사고 시 사상자 감소분을 추정해 본 결과, 자동차 안전도평가제도를 시행함으로써 자동차 안전도가 향상되어 2005년 1년 동안 교통사고로 인한 사망자는 약 1.51명, 부상자는 약 446명 감소한 것으로 나타났다.

The domestic car to car accident Perpendicular to side car crash in a car accident case, the proportion was the highest. Safety regulations and New Car Assessment Program tests to ensure safety in side impacts tend to strengthen regulatory requirements. Side Pole Impact of the road, trees and utility pole, etc. aspects of vehicle side impact crash tests and more intensive deformation and impact energy after the collision mitigation occurs due to a lack of space and will cause fatal injury to the driver. Being studied in this paper AE-MDB side impact test and Side Pole test change the body injury results data analysis and evaluation methods KNCAP hatch side impact applied to the phase comparison should investigate.

Recently a lot of social attention to the safety of the car is being poured. The government secure the safety of the car through the car safety standards and NCAP (car safety rating system), and has been an effort to inform its performance. However, the current Motor Vehicle Safety Standards and the evaluation system have been made only by the front-seat. So, attention to the safety of rear-seat is relatively much inferior. The purpose of this paper was undertaken to confirm the status of the rear seat safety in frontal crash. In this paper, we selected two sedan and two SUV. And we also use the following dummies. [5% -ile female , 50% -ile male , 5% -ile pregnant female(MAMA) , 6 year-old child (Q6)]. According to standard of NCAP frontal crash safety test, we performed full frontal sled test twice. Test pulse used the average deceleration of the test pulse that used in the NCAP frontal crash safety test for a total of 30 vehicles. According to the test results, we found that the Injury criteria of rear-seat passenger is higher than that of frontal-seat passenger. Injury criteria difference between male and female were not large. But, Injury criteria of Q6(was seated in CRS) was lower than any other dummies.

The frontal crash test methods and references are divided into two types. One is the full frontal crash test of us and Korea, the other is the Euro 40% offset deformable barrier frontal crash test. These two methods are used for Vehicle Safety Standards and NCAP. The purpose of this paper is to compare the crashworthiness and occupants injury of US full frontal crash test with those of Euro 40% offset frontal test. Four small passenger cars were tested for two test methods at each speed 56kph, 64kph. The results show that the chance of serious injury of 56kph full frontal crash test is higher than that of 64kph 40% offset, and 56kph full frontal crash test is appropriate to protect a head and chest.

In 1999, the Korean New Car Assessment Program(KNCAP) was initiated with the primary purpose of providing consumers with a measure of the relative safety potential of vehicles in frontal crashes. The side impact test was added to KNCAP in 2003. 24 passenger cars, 3 SUVs and 2 Vans were evaluated and the star ratings for the side impact tests have been reported. From 2008, the KNCAP changed the side impact dummy from EuroSID-1 to EuroSID-2 to improve the Flat Tops effect. Test results show that the dominant factor for the good star rating is the rib deflection of the EuroSID-2.

Whiplash injuries of the neck are one of the most common injuries reported from automotive rear impacts. Whiplash injuries can be reduced by changing geometry of head restraint. Therefore, geometries of head restraint were evaluated according to the test procedures of the Korea New Car Assessment Program (KNCAP) to improve safety of head restraint. In this study, nine vehicle’s head restraints were tested. As the test results, one head restraints is rated at “Marginal”, three head restraints are rated at “Acceptable” level, and the last five head restraints are rated at “Good” level.

In 1999 the New Car Assessment Program (NCAP) in Korea was initiated with the primary purpose of providing consumers with a measure of the relative safety potential of vehicles in frontal crashes. The side impact test was added to the Korean NCAP in 2003. The eight small passenger cars were evaluated and the star ratings for the side crashes were reported. The star ratings for the injury severities are estimated using conversion points from the head injury criterion (HIC) and the maximum value of the chest deflection, the viscous criterion, the abdominal force and the pubic symphysis force. According to the test results, the dominant factors for the star ratings are the chest injuries such as the chest deflection and the viscous criterion.

In 2010, the number of accidents of side crash of car to car crash incidence is equivalent to 51.6 percent of the 86,156 cases. It had the highest proportion in a whole car accident. Also in the second half of 2010, cars registration of greater than or equal to 1,400 ㎏ and less than or equal to 1,600 kg is equivalent to 24% of the condition in the domestic passenger cars registration, which is showing the highest number of status. Therefore, to guarantee security of side crash, we tested KNCAP moving barrier(950㎏) with the AE-MDB(1500㎏) reflecting characteristics and design of the car on the market today and studied the effects on the vehicle structure deformation and dummy injury compared to the moving barrier of KNCAP.
