Abstract

Visibility of lane marking is impaired at night, or in case of rain, and thereby threatens traffic safety. Recently, various studies and technology have been developed to improve lane marking visibility, such as the extension of lane marking life expectancy (up to 1.5 times), improvement of lane marking equipment, improvement of lane marking visibility (32.7%) by applying phosphorescent material mixed paint, and expressway lane design standards alternative (length 6m, gap 12m, width 13cm: 27.8% of painted surface are reduced) adoption with ergonomic analysis. In this study, a set of cost-benefit analyses was performed for the cases where such techniques were applied. Based on the literature review, 26.9% of traffic accidents would be prevented by improving lane marking visibility by 32.7%; accident reduction benefit was calculated as much as 12.5 billion KRW. Meanwhile, total increased cost when introducing phosphorescent material mixed paint and lane design standards alternative is calculated as 30.6 billion KRW. However, economic feasibility could not be secured with 0.41 of cost-benefit ratio when applied to the expressway network as a whole. Additionally, cost-benefit (B/C) analysis was applied to each of the top 20 night accident hot spots and the results of B/C ratios were between 0.67 and 4.20, showing that 11 out of 20 spot sections of expressway can have economic feasibility. This results indicate, with this kind of pavement marking applied to accident hot spots in rural expressway, better visibility and economic feasibility can be guaranteed through traffic accident reduction. Some limitations and future research agenda have also been discussed.

야간 혹은 우천시에 노면표시의 시인성이 저하되어 교통안전에 위협을 초래하고 있는 가운데, 본 연구에서는 최근 소개된 차선도색 장비 성능개량에 따른 노면표시 수명 연장(1.5배), 축광차선도료를 배합한 야광 노면표시의 시인성 개선(32.7%), 인간공학적 검토를 통한 고속도로 차선도색 설치규격 개선안(도색길이 6m, 빈길이 12m, 차선폭 13cm: 도색면적 27.8% 절감)을 도입하였을 때 종합적인 소요비용 및 사고절감 편익을 고려한 경제성분석을 통해 도입타당성을 제시하고자 하였다. 기존 문헌을 바탕으로 노면표시 시인성 32.7% 개선에 따라 26.9%의 사고감소 효과가 있는 것으로 나타났으며, 이에 대한 고속도로 교통사고 절감편익은 125억원으로 산정되었다. 야광차선 도입 및 설치규격 개선에 따른 총비용 증가분은 306억원으로 고속도로 일괄 도입시 경제성(비용-편익비 0.41) 확보가 어려운 것으로 나타났다. 야간 교통사고가 잦은 상위 20개 구간을 대상으로 각 구간별 경제성 분석을 수행한 결과, 구간에 따라 비용-편익비가 0.67~4.20으로 전체 20개 구간 중 11개 구간에서 경제성이 확보되어, 특히 지방부 고속도로 사고다발구간에 야광 노면표시 및 설치 규격 개선을 우선적으로 적용시 사고 감소에 따른 경제성이 존재하는 것으로 확인되었다. 연구의 한계와 향후 연구주제가 함께 논문의 말미에 토의되었다.
