다국어 초록 (Multilingual Abstract)

Since the first highway of Korea from Seoul to Inchon was constructed in 1969, so many other highways have been constructed and expanded throughout the country and transportations using these highways also have been increased.
Accordingly, occurrence of traffic accident on the highway increased year by year up to 2,500 cases in 1975 since that time. However, no research to prove the causes of the accident was reported.
In this reserch, a total of 9,448 cases of traffic accident on the highway in Korea was studied for the purpose of etiological analysis about the factors concerned with the occurrence of traffic accident. The data were collected from the accident record identified and preserved for 5 yearsfrom 1971 to 1975 by the Korea Highway Corporation.
The analyzed results were as follows;
1. Four to ten times of increase in accident occurrence rate was revealed during early dawn (3:00 a.m.∼6:00 a.m.) when drivers usually were fallen into sleep and fatigue in comparison with the least occurrence rate recorded from 8:00 a.m. to 10:00 p.m. Also the accident occurrence rate was higher in long way driving by 2∼2.5 times than short way driving less than 100km.
2. The highest occurrence(33.6%) was noted to happen in the course of the last quarter to the destination where the driver usually became relaxed from the alertness.
3. Accident occurrence rate was gradually decreased by 15% according to every 5 years of drivers' age increasement which represents the skillfulness of driving.
4. The proportion of accident occurrence due to defects of vehicle was only 14.2% of total causes.
5. The accident occurrence rate at precipitation was as high as 3 times of one at no-precipitation.
6. During the road surface was moist, or covered with water film, snow or ice, the accident occurrence rate was as high as 4 times of one during dry.
7. No change of accident occurrence rate due to change of traffic amount was found in this study.
