  • Recent advanced sensors and communication technologies have been widely applied to advanced safety vehicle (ASV) for reducing traffic accident and injury severity. To apply the advanced safety vehicle technologies, it is important to quantify the safety benefits, which is a fundamental for justifying application. This study proposed a methodology for quantifying the effectiveness of the advanced driver assistant system (ADAS), and applied the methodology to lane departure warning system (LDWS) and automatic emergency braking system (AEBS) which are typical advanced driver assistant systems. When the proposed methodology is applied to 2008-2010 gyeonggi-province crash data, LDWS would reduce about 10~14% of relevant crashes such as head-on, run-off-the road, rollover and fixed-object collisions on the road. In addition, AEBS could potentially prevent about 50% of total rear-end crashes. The outcomes of this study support decision making for developing not only vehicular technology but also relevant safety policies.

  • Recently, with the increase of the interest to global environmental problems, bicycle has been recognized as the most environmentally friendly transportation mode. To promote cycling, it is necessary to ensure road space that bicycle can keep running safely and smoothly. This paper aims to evaluate the district with rearranged road space and network, given priority to bicycle, comparing the traditional district which are given priority to car from viewpoints of environment, safety and accessibility. As evaluation indicators, the carbon dioxide emission on the environment. the number of collision between car and bicycle on safety and an accumulated frequency measure on accessibility were used. As the result, it was clarified that bicycle road measures to create bicycle road by reallocation of road space and form bicycle exclusive network were effective.

  • The Ministry of Land, Infrastructure and Transport (MoLIT) and the Korean Automobile Testing and Research Institute (KATRI) are supporting the development of Lv.3 automated vehicle (hereinafter, AV) technology by constructing an automated driving pilot city (as known as K-City) equipped with total 5 evaluation environments (urban, motorway, suburban, community road, and autonomous parking facility) which is a test bed exclusively for AV (2017~2018). An upgrade project is in a progress to materialize harsh environments such as bad weather (rain, fog, etc.) and reproduction of communication jamming (GPS blocking, etc.) with the purpose of supporting the development of Lv.4 connected & automated vehicle (hereinafter, CAV) technology (2019~2022). We intend to proactively establish a national level standard for CAV test-bed and test road requirements, test method, etc. for establishment of a road map for the construction of the test bed which is being promoted step by step and analyze and, when required, benchmark the case of China that has announced and is utilizing it. Through this, we plan to define standardized requirements (evaluation facility, evaluation system, etc.) on the test bed for the development of Lv.4/4+ CAV technology and utilize the same for the design and construction of a test bed, establishment of a road map for the construction of a real car-based test environment related to the support for autonomous driving service substantiation, etc. through provision of an evaluation environment utilizing K-City, and the establishment of a K-City upgrade strategies, etc.

  • In the era of the 4th Industrial Revolution, research and development on autonomous vehicles have been actively conducted all over the world. Under these international trends, the Ministry of Land, Infrastructure and Transport is actively promoting the development of autonomous vehicles aiming at commercialization of autonomous vehicles at level 3 or higher by 2020. In the level 3 autonomous vehicle, it is essential to transfer control between the driver and the vehicle according to driving situations. Prior to the full-fledged autonomous vehicle age, this study developed a representative scenario for the safety evaluation on take-over on expressways. To accomplish this, we developed a highway driving scenario first, and then developed six control transition scenarios based on 2014 highway traffic accident data and take-over data. The variables to be considered in the developed scenarios are divided into drivers, vehicles, and environmental factors. A total of 36 variables are selected.

  • The ISO 26262 standard requires a preliminary hazard analysis and risk assesment early in the development for automotive system. This is a first step for the development of an automotive system to determine the necessary safety measures to be implemented for a certain function. In this paper, we propose an ontology-based hazard analysis and risk assessment method for automotive functional safety. We use ontology to model the hazard and SWRL(Semantic Web Language) to describe risk analysis. The applicability of the proposed method is evaluated by the case study of an ESCL(electronic steering column lock) system. The result show that ontology deduction is useful for improving consistency and accuracy of hazard analysis and risk assessment.

  • 10년 후, 미래의 자동차는 더 이상 단순한 운송수단이 아닌 우리의 삶을 윤택하고 더욱 풍요롭게 만들어주는 일상의 공간(업무 휴식 정보)으로 진화 발전할 것이다. 이러한 자동차 패러다임 변화의 중심에는 지능형자동차 기술이 자리하고 있다. 지능형자동차 기술은 자동차산업뿐만 아니라 사회 경제 전반에 미치는 파급효과가 매우 크기 때문에 국가 경쟁력 강화를 위한 차원에서도 큰 가치를 지니고 있다. 또한 미래형자동차는 안전성 편의성 향상이라는 소비자들의 다양한 요구와 시장의 확대를 희망하는 기업의 요구가 잘 맞물려 있기 때문에 향후 기술개발에 대한 예산 확충 및 지원 확대가 절실히 필요하다. 지난 1990년대부터 지능형자동차 개발에 적극적으로 참여한 일본, 미국, 유럽 등 자동차선진국은 최근 각종 신기술을 개발해 시장에 내놓고 있다. 자동차 10대 강국 중하나인 한국은 21세기 세계 자동차시장 선점과 오는 2010년 세계 3위의 기술 강국으로 도약한다는 야심찬 계획을 세우고, 지난 2003년에 미래형자동차를 국가 '차세대 성장동력산업'으로 선정하였다. 이에 따라 국가연구개발사업인 '미래형자동차사업'을 출범시켰으며, 국내 자동차업계는 물론 대학 및 연구소 등과 연계하여 '지능형자동차' 등 3분야의 관련 핵심기술 개발에 박차를 가하고 있다. '지능형자동차 기술개발'이라는 비전과 목표를 달성하기 위해서는 IT기술과 자동차와의 융합기술 개발이 그 무엇보다 중요하다. 우리나라가 세계에 IT강국으로서 명성을 널리 자랑하고 있다는 점에서 지능형 자동차의 미래는 밝다고 할 수 있지만, 관련 분야의 인적자원 네트워크 구축이 보다 탄탄하게 다져지지 않는다면 이는 그저 '빛 좋은 개살구'에 지나지 않을 것이다. 끝으로 국내에서 진행되는 ITS 관련 프로젝트와 지능형자동차 개발 연구과제의 유기적 연계와 효율적 추진, 지능형 자동차 시험 평가방법 표준화, 국제 기술 표준화 및 안전규제에 적극 대응, 지능형자동차 신규제품 및 서비스의 도입을 위한 제도개선 및 정비 등에, 정부와 산 학 연이 지혜를 모아 중점 실행계획을 수립하고 행동으로 옮길 때 우리의 지능형 자동차 미래는 밝을 것이다.

  • In recent years, the emergence of virtual reality (VR Virtual Reality) technology has provided a new model of safety education, enabling users to learn and respond to disasters in a virtual safety education environment. However, the related VR products related to domestic and foreign R & D are relatively simple, there is no practical training on specific accident, and it is not practical enough to play a sufficient role in safety education. In this paper, the problems and disadvantages of VR technology applied in the field of automobile safety education as an example of automobile accident among the types of disasters are examined, and a system framework of automotive safety education based on VR technology is proposed. The vehicle safety education system proposed in this paper will help users to improve driving safety consciousness, to acquire safety knowledge in driving, and to acquire driving safety skill which is very important for automobile safety education. In addition, the design and production methods of safety education based on VR technology are considered to have important reference implications for the application of modern teaching and teaching theory by integrating with VR technology and developing related teaching materials products and finally introducing education.

To apply the advanced safety vehicle technologies, it is important to quantify safety benefits, which is a fundamental for justifying application. This study proposed a methodology for quantifying the effectiveness of the Advanced Driver Assistant System (ADAS) with the Analytic Hierarchy Process (AHP). When the proposed methodology is applied to 2008-2010 Gyeonggi-province crash data, ADAS would reduce about 10.18% of crashes. In addition, Adaptive Cruise Control, Automatic Emergency Braking System, Lane Departure Warning System and Blind Spot Detection System are expected to reduce about 10.43%, 10.17%, 9.96%, and 10.18%, respectively. The outcomes of this study might support decision making for developing not only vehicular technologies but also relevant safety policies.
