人脸识别是行人进行的人际判断之一。道路照明应增强天黑后这种判断的视觉部分。本文介绍了使用两种不同的程序进行的实验，识别和感知识别，调查为什么早期的研究导致不一致的结论的影响，光谱功率分布（SPD）对人脸识别。对于识别程序，采用两种观察持续时间（1秒和3秒）。这两个过程导致了类似的结论，在不同的距离识别能力。回顾这些和过去的结果表明，灯（SPD）的效果更有可能被发现时，任务是困难的，即小尺寸，简短的观察和正确命名的目标，而不是简单地从样本中挑选一张脸。
Face recognition is one of the interpersonal judgements carried out by pedestrians. Road lighting should enhance the visual component of such judgements after dark. This paper presents experiments carried out using two different procedures, identification and perceived recognition, to investigate why earlier studies have led to inconsistent conclusions about the influence of spectral power distribution (SPD) on face recognition. For the identification procedure, two observation durations were employed (1s and 3s). The two procedures led to similar conclusions regarding recognition ability at different distances. Review of these and past results suggests that an effect of lamp (SPD) is more likely to be found when the task is difficult, i.e. small size, brief observation and correctly naming the target rather than simply picking a face from a sample.
