| 摘 要： | 为了解决现行道路照明可见度计算过程中阈限亮度差的计算过于复杂的问题，基于ANSI／IESNARP-8-00规范中阈限亮度实验的计算模型，利用定值刺激法进行阈限对比实验和根据韦伯一费昔勒定律进行理论推导，分别得到了简化的阈限亮度差计算模型。为了使阈限亮度差计算模型更符合道路照明的实际情况，给出了用于修正模型的负对比修正系数、识别时间修正系数和年龄修正系数。分别利用这2个模型和RP-8—00中的模型计算了某条件下的道路照明可见度，结果表明，用这2个简化模型的计算得到的结果与用RP-8-00中的模型计算得到的结果吻合。

| Abstract: | In order to simplify the calculation of threshold luminance difference, based on threshold luminance difference experiment calculation model of ANSI/IESNA RP-8-00, two simplified calculation models were proposed with constant stimuli experiment and Weber-Fechner＇s Law, respectively. Negative contrast correction coefficient, identification time correction coefficient and age correction coefficient were obtained. A road lighting visibility was calculated with these two models and the model of RP-8-00 as a case study. It is found that the visibility values calculated from these three models are in good agreement. |
