Secondary accident is common type of accident which occurs in Korean highway tunnels. Fatality rate of secondary accidents in highway tunnels is six time higher than primary accidents. Video type VMS is a new way of providing information to road users which was recently introduced by Korean government to prevent secondary accidents in highway tunnels. In this study we compared changes in driver's behavior when information is provided by Text type and Video Type VMS. In addition to analyze effects of secondary accident reduction, driving behavior was analyzed based on providing advance information by video type VMS at tunnel entrance. Analysis showed that both text type and video type VMS has similar effect on driver behavior. Video type VMS showed positive effect on driver's behavior to prevent secondary accident when information is provided 1km ahead of accident. Considering there results and the short-term memory characteristics of driver, it was determined that information should be provide at about 650m from the entrance of the tunnel. The results of this study are consistent with the requirement that VMS should be installed at least 500m ahead of tunnel and produce more accurate providing information points. 650m is also appropriate interval for providing information in tunnel to cope with an accident ahead.

DEA를 이용한 교통사고 잦은 곳 개선사업 효율성 측정방안 연구
김형규,이수범,엄대룡,원동욱,신소명,Kim, Hyung Kyu,Lee, Soo Beom,Eom, Dae Lyoung,Won, Dong Uk,Shin, So Myoung 한국안전학회 2017 한국안전학회지 Vol.32 No.5
Over the past 30 years, the business effects of the improvement project at black spot have been decreasing since 2010, with a reduction in the amount of government spending, coupled with proposing a uniform improvement plan. In order to promote more efficient improvement projects, it is necessary to evaluate the efficiency of local governments and improve the business methods of local governments with low efficiency. However, more sophisticated efficiency analysis methods are needed. Because in previous studies have been limited to the analysis of effects before and after the project through the simple before-after analysis. For this purpose, this study analyzed the efficiency of improvement project at black spot by local governments in Gyeonggi-do using DEA to compare and analyze efficiency in various fields. As a result, Goyang, Seongnam, Paju, Hanam and Yangju showed high efficiency local governments. For local governmetns with low efficiency, the improvement projets to improve efficiency were divided into civil engineering work, structure work, pavement work, additional work and transportation work, and the appropriate construction ratios of each local government were analyzed and presented.

도심도로 자율협력주행을 위한 자율주행시스템의 안전성 평가 시나리오 개발 연구
강민지 ( Kang Min Ji ),박신형 ( Park Shin Hyoung ),신소명 ( Shin So Myoung ),이한빈 ( Lee Han Bin ),김지호 ( Kim Ji Ho ) 한국도로교통공단 2022 교통안전연구 Vol.41 No.1
본 연구는 레벨 4 수준의 도심도로 자율협력주행에 대한 안전성 평가 시나리오 개발을 목적으로 한다. 시나리오 설계를 위해 레벨 4 자율협력 주행에서 요구되는 기술 수준과 V2X 기반의 자율주행 시스템의 아키텍처를 검토하고, 다양한 측면의 안전성 평가 중 차량의 동적 운전 임무(DDT, Dynamic Driving Task)에 해당하는 기능인 도로 주행 시 차량을 운행하는 데 필요한 전술 기능(Tactical Function)과 운영 기능(Operational Function)을 안전성 평가의 대상으로 설정하였다. 본 연구의 결과는 자율협력주행 상황의 전반적인 시나리오를 개발할 수 있는 방법론을 제시함으로써 효과적이고 체계적인 안전성 평가 시나리오를 통해 자율협력 주행 기술의 안전성 확보에 기여할 것으로 기대된다. The purpose of this study was to develop a safety evaluation scenario for cooperative Level 4 autonomous driving on urban roads. To design scenarios effectively, we first reviewed technologies required by Level 4 autonomous driving and the architectures of V2X-based autonomous driving systems. Tactical Function and Operational Function are both required for vehicles to drive on the road, and these aspects of safety assessment are features of the dynamic driving task. The results of this study may contribute to improving the safety of cooperative autonomous driving technologies via an effective and systematic safety evaluation scenario by presenting a method for the development of scenarios for cooperative autonomous driving situations.
