Abstract

Recently, advanced sensors and communication technologies have been widely applied to advanced safety vehicles for reducing traffic accidents and injury severity. 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.

교통사고 및 사고로 인한 사상자수 감소를 위해 기존의 자동차에 각종 센서나 통신기술 등의 첨단기술을 융합한 첨단안전자동차에 대한 연구가 활발히 진행 중에 있다. 이러한 첨단안전자동차의 시장진입 및 관련 기술도입을 위해서는 첨단안전자동차 기술의 효과분석을 통한 도입 타당성 평가가 필요하다. 본 연구에서는 계층화분석법(AHP: Analytic Hierarchy Process)을 이용하여 첨단안전자동차 기술 중 사고예방의 기능을 가지는 첨단운전자지원시스템의 효과추정 방법론을 제시하였다. 제시한 효과추정 방법론을 이용하여 적응형순항제어장치(ACC: Adaptive Cruise Control), 자동비상제동장치(AEBS: Automatic Emergency Braking System), 차로이탈경고장치(LDWS: Lane Departure Warning System), 사각지역감시장치(BSDS: Blind Spot Detection System)의 네 가지 시스템을 통합하여 평가하였다. 분석결과, 운전자지원시스템의 효과는 약 10.18%의 사고감소 효과가 있는 것으로 나타났으며, 적응형순항제어장치는 10.43%, 자동비상제동장치는 10.17%, 차로이탈경고장치는 9.96%, 사각지역감시장치는 10.14%의 사고감소 효과가 있을 것으로 추정되었다. 본 연구의 결과는 추후 첨단안전자동차 시스템 도입시 도입타당성을 제시하는데 기초자료로써 활용이 가능할 것으로 기대된다.
