도로조명시설의 설치 형태에 따른 운전자의 시선변화와 신체변화를 연구하였다. 야간 운전시 도로 조명 등기구의 설치위치에 따른 운전자의 시선, 감성, 행동의 변화와 이의 상관관계를 조사하여 조명 조건이 운전자에게 어떠한 영향을 주는지 비교 측정하였다. 특히 라인형태의 낮은 조명이 운전자 시선의 영향여부를 중점적으로 분석하였다.

This study conducted a subjective evaluation of brightness perception and visual discomfort according to dimming speeds and CCTs(Correlated Color Temperatures). Dimming speeds of two different CCT lights(2,700K, 6400K) were set to 1.7%/s, 3.3%/s, 5.0%/s, 6.7%/s, and 10.0%/s respectively. Subjects checked the time when they perceived the change of the brightness and visual discomfort. As a result, when dimming speeds were 1.7%/s, 3.3%/s, 5.0%/s, 6.7%/s, more than half of subjects responded the change of the brightness in 55.0~45.0% dimming ratios, and felt the visual discomfort in 35~25% dimming ratios. When the brightness was changed, dimming level responded to the brightness perception of hight CCT(6,400K) was higher about 8.0% then dimming level responded to the brightness perception of low CCT(2,700K). Dimming level responded to the visual discomfort of low CCT(2,700K) was higher about 5.0% then dimming level responded to the visual discomfort of hight CCT(6,400K).
