Abstract

Recently, interest in safety has been increasing in every area, especially in the field of transportation. The accurate evaluation of the stability of road facilities is needed to improve the level of safety in the field of transportation and the application of new technologies is required to reduce the number of natural disasters. In this study, the wind data were compared and analyzed according to the type of measurement, and an evaluation of the stability of road signs using the wind data was conducted. In addition, a stability plan to secure road signs was elaborated and its effect on the wind load was analyzed. It was found that the wind data measured by a mobile atmospheric observing system (MAOS) was 2.43 times bigger than that measured by the Korea meteorological administration (KMA) and road weather information system (RWIS). In terms of their stability, the road signs were susceptible to failure caused by gusty winds and it was found necessary to ensure their stability. In the future, it will be possible to evaluate the stability of road facilities using road line weather data and the application of wind load reduction technologies is expected to improve road safety.

최근 안전에 대한 관심이 크게 높아지고 있으며, 도로 교통 분야에서도 안전의 필요성이 대두되고 있다. 이에 따라 도로 교통 분야의 안전성 제고를 위하여 도로 시설물의 객관적인 안정성 평가가 필요하며, 자연재해 대비를 목적으로 도로 시설물의 피해 저감이 가능한 기술 적용이 필요하다. 따라서 본 연구에서는 계측 유형별 풍속 데이터와 이를 적용한 도로표지의 구조 안전성을 비교 분석하여 기상 계측 유형의 시설물 안전성 평가에 대한 영향을 분석하였다. 더불어 도로표지의 안정성 확보 방안을 도출하였으며, 도출한 안정성 확보 방안 중 풍하중 저감 기술에 대한 효과를 분석하였다. 계측 유형별 풍속 데이터 분석 결과, 기상관측차량시스템의 풍속 데이터는 기상청과 도로기상정보시스템의 풍속 데이터에 비하여 약 2.43배로 크게 나타났다. 또한 기상관측차량시스템의 풍속 데이터를 적용한 도로표지의 안정성 검토를 통하여 돌풍으로 인한 도로표지의 파괴 및 전도의 가능성이 있는 것으로 분석되며, 안정성 확보 방안 마련이 필요한 것으로 판단된다. 도로 선형 단위의 기상 데이터를 활용하여 도로 시설물의 객관적인 안정성 분석과 모니터링이 가능할 것으로 판단되며, 풍하중 저감 기술 적용을 통하여 도로 안전도의 제고가 기대된다.
