摘　　要：针对阈值增量在评价动态眩光方面存在的不足之处,从人眼视觉特性出发,提出一种基于亮度对比分析原理的动态眩光评价方法,建立动态眩光评价模型。以人眼视野范围的变化为切入点,研究驾驶员行驶速度的改变对其感受自身所处照明环境等效光幕亮度的影响因子,利用多种数学模型对行驶速度与对应行驶速度下动、静态等效光幕亮度比率之间的关系进行曲线估算,探索动、静态眩光差异系数。实验结果表明,动、静态眩光差异系数与驾驶员行驶速度呈正相关;从拟合优度和方差检验等方面分析,动静态眩光差异系数与行驶速度之间的关系用指数型函数模型描述效果最佳。该评价方法可为动态眩光评价体系的建立奠定基础,为我国道路照明设计提供设计依据与解决方案。In light of the shortcomings of threshold increments in evaluating dynamic glare,starting from the visual characteristics of human eyes,this paper proposes a dynamic glare evaluation method based on the principle of brightness contrast analysis and builds a dynamic glare evaluation model.With the change in the field of view of human eyes as the starting point,the influence factor of the change in driving speed on the driver’s perception of the equivalent light curtain brightness in the lighting environment is studied.A variety of mathematical models are used to determine the relationship of driving speed with the ratio between dynamic and static equivalent light curtain brightness at the corresponding driving speed to explore the dynamic and static glare difference coefficient.The experimental results show that the difference coefficient is positively correlated with the driving speed of the drivers.From the analysis of goodness of fit and variance test,the relationship between the dynamic and static glare difference coefficient and the driving speed can be best described with an exponential function model.This evaluation method can lay a foundation for the establishment of a dynamic glare evaluation system and provide design basis and solutions for road lighting design in China.
