Abstract: Currently, the mechanisms of non-visual effects of road lighting environments on drivers are unclear. In this paper, Electroencephalography (EEG) and other measures were used to record physiological and psychological indicators during driving at different correlated color temperature(CCT) levels (3500k vs. 4500k vs. 5500k vs. 6500k), with the aim of preliminarily verifying the existence of non-visual effects of the lighting environment on drivers on urban motor vehicle roads. The results suggest that 3500k and 4500k help to improve the subjects' mood, while 5500k and 6500k are more likely to induce negative emotions in the subjects.
