This research de떠 s with the traffic accident of intersection in the case of Korea expressway. The purpose of this research is to analyze the hazardous locations and to clarify the reasons why they are dangerous. In pursuing the above, 195 intersections are classified into various types; the freeway traffic accident records from September 1, 1998. to December 31, 2003. are collected; the geometric structures Gnterchange angles, the number of lanes, radii of curvature, and grades) are investigated; and the nationwide freeway traffic volume are calculated by the freeway origin destination survey to construct the base of the research materials. From these collected materials, this research is advanced into a close exarnination of hazardous intersections and connecting roads, hence producing a various meaningful results. The main research results are as follows. This research exhibits the data of the hazardous intersections and connecting roads which are closely exarnined by applying the upper limit control. Based on the significance probability of 99.5%, the hazardous intersections are found to be 13 intersections including ’Kyung-Ju interchange'. Moreover, in the case of connecting roads, 10 hazardous intersections are found including ‘East Kwang-Ju No.2’ connecting road. Meanwhile, it can be decided as the special characteristics of hazardous intersection if the angle of intersection is big, and has many lanes of connecting roads. The hazardous connection roads have a small radius of curvature, a large grade, and a low traffic volume despite many lanes.
