Nocturnal roadway lighting, in particular, has a substantial impact on drivers\u2019 physiological and psychological states, influencing behavior and safety. This study investigates the non-visual effects of correlated color temperature (CCT: 3000K vs. 4000K vs. 5000K) and illuminance levels (20 lx vs. 30 lx) of urban motor vehicle road lighting on driver alertness during various driving tasks. Conducted between 19:00 and 20:30, the experiments utilized a human-vehicle-light simulation platform. EEG (\u03b2 waves), reaction time, and subjective evaluations using the Karolinska Sleepiness Scale (KSS) were measured. The results indicated that the interaction between CCT and illuminance, as well as between CCT and task type, significantly influenced driver alertness. However, no significant effect of CCT and illuminance on reaction time was observed. The findings suggest that higher illuminance (30 lx) combined with medium CCT (4000K) effectively reduces reaction time. This investigation enriches related research, provides valuable reference for future studies, and enhances understanding of the mechanisms of lighting\u2019s influence on driver alertness. Moreover, the findings have significant implications for optimizing the design of urban road lighting.<\/jats:p>","DOI":"10.3390\/s24154927","type":"journal-article","created":{"date-parts":[[2024,7,30]],"date-time":"2024-07-30T11:11:25Z","timestamp":1722337885000},"page":"4927","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["An Investigation into the Effects of Correlated Color Temperature and Illuminance of Urban Motor Vehicle Road Lighting on Driver Alertness"],"prefix":"10.3390","volume":"24","author":[{"given":"Quan","family":"Chen","sequence":"first","affiliation":[{"name":"School of Mechanical Engineering, Southeast University, Suyuan Avenue 79, Nanjing 211189, China"}]},{"given":"Zelei","family":"Pan","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Southeast University, Suyuan Avenue 79, Nanjing 211189, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3419-0952","authenticated-orcid":false,"given":"Jinchun","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Southeast University, Suyuan Avenue 79, Nanjing 211189, China"}]},{"given":"Chengqi","family":"Xue","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Southeast University, Suyuan Avenue 79, Nanjing 211189, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1070","DOI":"10.1126\/science.1067262","article-title":"Phototransduction by Retinal Ganglion Cells That Set the Circadian Clock","volume":"295","author":"Berson","year":"2002","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"600","DOI":"10.1523\/JNEUROSCI.20-02-00600.2000","article-title":"A Novel Human Opsin in the Inner Retina","volume":"20","author":"Provencio","year":"2000","journal-title":"J.
