Abstract
In order to examine the effects of circadian rhythm in subjective alertness on the occurrence of traffic accidents, the authors investigated the occurrence rate of traffic accidents adjusted to traffic volume in Seoul and the relative rate of fatal accidents versus total traffic accidents in Korea at different times of day in 1991. We analyzed these data in relation with the circadian rhythm in subjective alertness. The results were as follows. Both the occurrence rate of traffic accidents adjusted to traffic volume and the relative rate of fatal accidents versus total traffic accidents were the highest at 3-4 a.m., known as the time period of the lowest subjective alertness. They were negatively correlated with subjective alertness (p<0.05, p<0.001). In conclusion, it is suggested that the circadian rhythm of subjective alertness should have a significant effect on the occurrence of traffic accidents despite many confounding factors such as driving environments.
저자들은 각성도의 일주기 리듬이 교통사고 발생에 어떤 영향을 미치는가를 알아보기 위해 교통량을 고려한 시간대별 교통사고 현황과 시간대별 전체사고에 대한 사망사고의 상대적 빈도를 조사하여 주관적 각성도의 일주기 리듬과 비교하여 보았다. 그 결과 일주기 리듬 상 각성도가 가장 떨어지는 시기라 알려져 있는 오전
