It is very important to research drivers' visual behavior. Angle of vision is very important and accounts for more than 90% as the source of driving information. In curve sections, drivers can know the front circumstances and drive more safely and comfortably through facilities guiding their eye movements. Therefore, the standards of installation and effectiveness of these facilities to guide drivers' gaze need to be reconsidered considering characte- ristics of drivers' eyes. The national road no. 34 (Jincheon IC, Buckamri-Yipjangmun section), which is a high-accident-frequency location, is chosen for experimental place. The aim of this study is to understand the process of drivers' visual movement which is drivers' visual behavior and to check the facilities to guide their eyes. Another goal of this study is to improve facilities to guide drivers' eyes on a result basis of considering drivers' visual behavior especially for traffic safety in a high-accident-frequency curve sections. 운전에 필요한 외부 정보는 90% 이상을 운전자의 시각에 의존하고 운전자의 시각활동과 이에 따른 인지, 판단, 행동에 이르는 일련의 과정을 통하여 이루어짐으로 운전자의 시각활동 특성을 파악하는 것은 중요한 의미를 갖는다. 특히 곡선부에서는 원활한 운전성을 확보하고 운전중의 교통안전 증진을 위하여 시선유도 시설을 설치하고 운전자에게 전방의 상황을 사전에 제공하고 있다. 따라서 시선유도시설은 무엇보다 운전자의 시각특성이 반영된 관점에서 시선유도 시설의 설치기준, 효용 등이 재검토되어야 할 필요가 있다. 따라서 본 연구에서는 위와 같은 배경을 바탕으로 교통사고 다발지점으로 지정되어 있는 국도 34호선(진천IC, 벽암리∼입장면 구간, 편도1차로)을 대상으로 운전자의 시각행태와 시선유도 시설을 확인하는 시각적 일련의 과정을 파악하는데 주 목적을 두었다. 그리고 이 결과를 바탕으로 곡선부 교통사고 다발지점에서의 교통안전 증진을 위하여 시선유도시설에 관한 운전자 시각행태를 파악하고 향후 정비되어야 할 방향 검토에 목적을 두었다.

The work analyzes the existing situation and defines special problems concerning traffic accidents in the two countries. The report is divided into three parts: 1) Using the global approach of SMEED, the data were evaluated using multiple regression analysis, and homogeneous groups of countries were defined by cluster analysis. In the global approach, the linear model is better than SMEED's non-linear model in explaining the number of fatalities. Among the different groups of countries, the linear approach was found to be better suited for industrialized countries and the non-linear approach better for the developing countries. T도 comparison of traffic fatality data for the Federal Republic the developing countries. The comparison of traffic fatality data for the Federal Republic of Germany and the Republic of Korea showed different regression equations during the same time period. 2) The BOX/JENKINS time series analysis on a monthly basis points out clearly similar seasonal patterns for the two countries over the years studied. The decrease in traffic accidents following the intensification of the safety belt requirement was proved in the ARIMA model. It amounts to 7 to 8 percent fewer personal injury accidents and fatal accidents. The identified increase in safety in the Federal Republic of Germany since the 1970s is mainly due to the reduction of accident severity in residential areas. 3) Speeds and headways on motorways in th3e two countries were also compared. The measurements point out that German road users drive faster, take more risks, and accept shorter time gaps than Korean road users. However, the accident statistics show accident rates for Korea that are several times higher than those in the Federal Republic of Germany.
