逆反射系统在高速公路隧道中的应用研究

Application of Retroreflective System in Shuang Shan Tunnel of Guizhou Zhipu Expressway

文中结合驾驶人的视觉特性和视觉需求,构建高速公路隧道内部逆反射系统,提出一种基于驾驶人视觉需求的高速公路隧道逆反射系统设计方法,并在贵州织普高速双山隧道进行推广应用和工程示范。通过依托项目室内仿真实验发现,反光环可以一定程度缓解驾驶人的弯道错觉效应,当弯道路段可见反光环的个数为3个时,具有良好的诱导效果;此外对逆反射系统及照明系统进行眼动实验发现,设置逆反射系统的隧道在驾驶人的视距视区及瞳孔变动方面优于仅设置照明系统的隧道,对高速公路隧道中部视错觉及视距视区具有很好的改善效果,可以有效提高驾驶人的速度感知能力和距离感知能力,缓解视错觉效应,提升视距扩大视区,有利于提高驾驶人在高速公路隧道的行车安全性。

In this paper,according to the driver's visual characteristics and needs,the internal retroreflection system of highway tunnel is constructed,and a design method of highway tunnel retroreflection system based on the driver's visual needs is put forward,which is applied and demonstrated in Shuang Shan Tunnel of Guizhou Zhipu Expressway.Relying on the project,through indoor simulation experiment,it is found that the retro-reflection system ring can alleviate the driver's visual illusion effect to a certain extent.When the number of visible reflective rings in road curved sections is three,it has good guidance effect.In addition,eye movement experiments are carried out on the retroreflection system and lighting system.It is also found that the tunnel with retroreflection system is better than that with lighting system only in visual range and pupil variation.And the retroreflection system has a good improvement effect on the visual illusion and sight distance visual area in the middle of expressway tunnel,which can effectively improve the driver's speed perception ability and distance perception ability,expand the visual area,and help improve the driver's driving safety in expressway tunnel.
