【摘要】：公路隧道出口段亮度变化情况会严重影响驾驶员视觉心理负荷,其亮度优化计算应该综合考虑行车安全和节能环保的要求。通过隧道出口段不同环境照度和运行时间情况下驾驶员视觉特性试验,采用定性和定量相结合的方法研究了瞳孔面积与环境照度之间的变化规律,同时结合节能环保的要求建立了公路隧道出口段最佳亮度计算的多目标优化模型,采用系统聚类的方法对隧道出口照明区段进行聚类分析,并给出了模型求解的方法。最后,以包(头)茂(名)高速公路南五台隧道为例进行了实证研究,基于模型计算出各聚类区段最佳照明亮度。结果表明,隧道出口段亮度设置应该是一个渐变过程,且应该更加注重洞口20 m以内的亮度要求。
[Abstract]:The luminance change of the exit section of highway tunnel will seriously affect the visual psychological load of the driver. The optimal calculation of the luminance should take into account the requirements of driving safety and energy saving and environmental protection.The variation of pupil area and ambient illumination was studied by means of qualitative and quantitative analysis through the pilot visual characteristic test under different environmental illumination and operating time at the exit of the tunnel, and the method of qualitative and quantitative analysis was used to study the relationship between pupil area and environmental illumination.At the same time, a multi-objective optimization model for the optimal luminance calculation of the exit section of the highway tunnel is established according to the requirements of energy saving and environmental protection. The method of systematic clustering is used to analyze the lighting section of the tunnel exit, and the method to solve the model is given.Finally, taking Nanwutai Tunnel of Bao (Tou) Mao (Ming) Expressway as an example, the optimal lighting brightness of each cluster section is calculated based on the model.The results show that the luminance setting of tunnel exit section should be a gradual process and more attention should be paid to the luminance requirement within 20 m of the tunnel entrance.
