超特长隧道特殊光环境的对比试验研究

Comparative Experimental Study on Special Light Environment ofSuper-Long Tunnel

为了对超特长隧道特殊光环境减少疲劳驾驶的作用进行定量分析,选取光源色温改变、彩色灯光带、LED点光源像素矩阵、高清图像投影等特殊光环境方案,开展真实环境下的实车驾驶对比试验,利用眼动仪和生理记录仪采集驾驶员的眼球运动行为参数和生理指标,建立起隧道内视觉环境与驾驶员视觉行为特征及生理反应的联系,提出隧道特殊光环境方案的选择建议。

In order to quantitatively analyze the effect of special light environment on reducing fatigue driving in super-long tunnel,special light environment schemes,such as color temperature change of light source,color light band,pixel matrix of LED point light source and high-definition image projection,are selected to carry out real-world driving test.Eye movement behavior parameters and physiological indexes of drivers are collected by eye tracker and physiological recorder.The relationship between the visual environment in the tunnel and the driver′s visual behavior and physiological response is established,and suggestions on the selection of special light environment for tunnels are put forward.
