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.
