乌尉天山胜利隧道进口段视感照度补偿分析

Analysis on illumination compensation of visual perception at entrance of Wuyu Tianshan Shengli Tunnel

为解决高海拔公路隧道路段短时照度剧烈变化导致驾驶人视感不适的问题,以乌尉天山胜利隧道为研究对象,模拟高海拔天气照度变化,设计隧道模型分析隧道进口段照度变化规律,得到照度折损系数曲线。判断视感适应阈值,建立驾驶人视感实时补(逆)偿原理模型。实验结果表明:实现进口段亮度连续优化补偿的范围为10~296.1 cd/m^(2)。本文为我国其他高海拔地区视感补偿提供科学计算方法。

In order to solve the problem of visual discomfort caused by the sharp change of short-term illumination in high-altitude highway tunnel sections,the Wuyu Tianshan Shengli Tunnel is taken as the research object to simulate the high altitude illumination change and design a tunnel model to analyze the illumination change law of the tunnel entrance.The illumination loss coefficient curve is obtained.The visual perception adaptive threshold is judged,and the principle model of real-time visual perception compensation(inverse)for drivers is established.The experimental results show that,the range to realize the continuous optimization compensation of brightness at the entrance is 10~296.1 cd/m^(2).It provides a scientific calculation method for the visual perception compensation in other high altitude areas in China.
