行人可以通过其他线索中的面部表情来判断另一个人的意图，而在天黑后帮助进行这种评估是道路照明的目的之一。先前的研究对于灯光谱是否影响做出此类判断的能力给出了不同的结论。使用更类似于行人行为的条件进行了一项实验，使用演员描绘与六种普遍认可的情绪相对应的面部表情的照片作为目标。使用强制选择程序、在两种类型的灯下以及彩色和灰度照片来寻求响应。灯的类型和图像颜色都没有对正确识别面部表情所传达的情感的频率产生显着影响。
A pedestrian may judge the intentions of another person by their facial expression amongst other cues and aiding such evaluation after dark is one aim of road lighting. Previous studies give mixed conclusions as to whether lamp spectrum affects the ability to make such judgements. An experiment was carried out using conditions better resembling those of pedestrian behaviour, using as targets photographs of actors portraying facial expressions corresponding to the six universally recognised emotions. Responses were sought using a forced-choice procedure, under two types of lamp and with colour and grey scale photographs. Neither lamp type nor image colour was suggested to have a significant effect on the frequency with which the emotion conveyed by facial expression was correctly identified.
