摘要

Illuminance, luminance and spectral outputs of several roadway lighting systems were measured at the driver's eyes position. While viewing the road, drivers' gaze directions along with pupil dilation are measured under the dynamic lighting conditions. At normal driving speeds, the luminance changes were generally slower or comparable in speed to the two fast visual adaptation mechanisms: neuronal adaptation and pupillary response, but much faster than photochemical adaptation. This paper applies a simple exponential model for photochemical adaptation to the varying luminance conditions measured on several roadways. Under empty road conditions, the effective luminance adaptation changes appear to be on the order of one percent of the physical variation. This result could have significant implications for the computation of small target visibility on the roadway.
