In order to simplify the calculation of threshold luminance difference
based on threshold luminance difference experiment calculation model of ANSI/IESNA RP800
two simplified calculation models were proposed with constant stimuli experiment and WeberFechner'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 RP800 as a case study.It is found that the visibility values calculated from these three models are in good agreement.
