隧道减光格栅段全天候路面照度计算模型
All-weather Road Illuminance Calculation Model for Tunnel Light Reduction Grille Section
摘要
Abstract
Understanding the characteristics of road illuminance distribution and temporal variation in the tunnel light reduction grille section is essential for the design of light reduction grilles and the evaluation of the lighting environment.The paper constructs an all-weather road illuminance calculation model for the tunnel light reduction grille section that takes into account both direct sunlight and sky scattering based on solar radiation theory and the CIE luminance distribution function.The accuracy and effectiveness of the model are validated through measured data.The results indicate that the model can accurately predict the spatiotemporal variations of illuminance on the bright and dark areas of the road surface in the light reduction grille section under different seasons and weather conditions.The calculated results aligh well with the measured data,with an average deviation percentage of less than 8％.Increasing the number of sky elements can enhance the calculation accuracy of the model proposed in this paper,with a greater impact on the illuminance calculation values in the dark areas of the road surface.Considering both accuracy and computational efficiency,it is recommended to divide the sky into 12 layers with a total of 247 sky elements when applying this model.关键词
