Abstract

To minimize the degree of damage in the SMART highway's punctuality and safety occurred from the car-barrier collisions, the impact conditions for longitudinal barriers in SMART highway was determined to be significantly larger than the existing maximum impact conditions. Results from computer simulation runs show that the existing domestic highest-performance roadside barrier did not satisfy the suggested impact conditions. The newly developed N-class barrier designed with computer simulation model and verified by full-scale crash tests has satisfied the SMART highway impact conditions in terms of occupant safety indexes and structural adequacy.

본 연구에서는 충돌사고시 스마트하이웨이의 정시성과 안전성의 손상정도를 최소화 하도록 스마트하이웨이의 종방향 베리어 충돌조건으로 기존의 충돌조건보다 상당히 상향된 충돌조건이 제시된다. 스마트하이웨이 충돌조건을 적용하여 기존 국내 최고 성능등급 베리어에 대한 컴퓨터 시뮬레이션 결과 탑승자 안전도를 만족하지 못하였다. 스마트하이웨이 충돌조건에 만족하는 베리어 개발을 위해서 컴퓨터 시뮬레이션에 의한 설계를 수행하고 실물차량 충돌시험을 통한 성능 검토결과 개발된 N등급 베리어가 탑승자 안전지수와 구조적 적절성을 만족하였다.
