摘要
文中在武汉黄龙山隧道开展实车试验,以驾驶人注视持续时间和频率、扫视持续时间和频率为指标,分析普通路段、桥下阴影段、以及隧道入口段的变化规律,并构建驾驶负荷评价模型,对隧道入口区域进行评价.结果表明:驾驶人在桥下阴影段的注视、扫视持续时间总体较普通路段高,但较隧道入口段低,而注视、扫视频率呈相反变化趋势;当隧道入口区域前存在阴影效应时,视觉指标离散度增大,初次阴影效应会使驾驶人视觉指标短时发生较大变化,连续阴影效应会使驾驶人眼动行为逐渐趋于不良状态,在隧道入口段黑洞效应的出现会导致视觉指标突变,阴影效应和黑洞效应会显著提高驾驶负荷.
Abstract
A full-scale vehicle test was carried out in Huanglongshan Tunnel in Wuhan.Taking the du-ration and frequency of driver's gaze and the duration and frequency of glance as indicators,the chan-ging laws of ordinary road sections,shadow sections under the bridge and tunnel entrance sections were analyzed,and a driving load evaluation model was constructed to evaluate the tunnel entrance ar-ea.The results show that the duration of driver's gaze and glance in the shadow section under the bridge is generally longer than that in the ordinary section,but lower than that in the tunnel entrance section,while the frequency of gaze and glance shows an opposite trend.When there is shadowing effect in front of the tunnel entrance area,the dispersion of visual indicators increases.The first shad-owing effect will make the driver's visual index change greatly in a short time,and the continuous shadowing effect will make the driver's eye movement behavior tend to be bad gradually.The appear-ance of the black hole effect at the entrance of the tunnel will lead to the sudden change of visual indi-cators,and the shadowing effect and black hole effect will significantly increase the driving load.
