摘　　要：目的随着科学技术的发展,虽然空运和铁路两种运输方式越来越受人们的欢迎,但公路仍然是中国现阶段最主要的运输方式之一,隧道是公路的一部分,为了保证车辆安全通过隧道,驾驶员的视觉感知是当今研究的热点。方法分析隧道照明的特殊结构,结合人眼中间视觉可见度的特征,构建基于隧道照明中间视觉可见度的模型。结果获得人眼中间视觉的敏感波长范围,建立中间视觉可见度的函数关系式,并模拟设置合理的隧道照明参数。通过实验验证了在中间视觉下,人眼的可见度和清晰度达到最佳。结论构建的基于隧道照明中间视觉可见度的模型能提高人眼的视觉效果,保障车辆安全通过隧道,为隧道照明设备设置提供参考价值。Objective With the development of science and technology,air and railway transportation methods are becoming more and more popular,but roads are still one of the most important transportation modes in China at this stage.And to ensure the safety of vehicles passing through the tunnel as a part of the highway,the driver’s visual perception is a research hotspot.Methods This paper analyzed the special structure of tunnel lighting,and in combination with the characteristics of the intermediate visual visibility of human eyes,it studied a model based on the intermediate visual visibility of tunnel lighting.Results The sensitive wavelength range of the intermediate vision of human eyes was obtained,the function relationship of the intermediate vision visibility was established,and the parameters under reasonable tunnel lighting were simulated.It was experimentally verified that the visibility and sharpness of human eyes reached the maximum under intermediate vision.Conclusion The constructed model based on the intermediate visibility of tunnel lighting can improve the visual effect of the human eyes and ensure vehicles safe passage through the tunnel,providing a positive reference value for tunnel lighting.
