摘要
为研究不同车型驾驶人在小半径公路短隧道入口环境中的视觉负荷,选择云南省国省干线平曲线半径为255m的公路隧道开展实车实验.利用Dikablis Professional眼动仪系统,以瞳孔面积变化速度为指标,比较瞳孔变动的差异,分析不同车型对视觉负荷和驾驶安全的影响.研究结果发现,大货车驾驶人的瞳孔面积变化平均速度显著比小客车驾驶人更快、波动范围更小,大货车与小客车驾驶人瞳孔变动速率波峰分别位于0~10m与5~15m处;当在入口段区域后可视隧道出口时,大货车与小客车驾驶人瞳孔面积变化速度均会产生波动,大货车驾驶人在瞳孔变动峰值过后的变化速度离散性更大.研究结果表明,大货车驾驶人的暗适应位置点距离洞门更近,在隧道入口段行驶时存在更严重的视觉负荷,行车安全性较差.
In order to study drivers' visual load of different types in short tunnel entrance environment of small radius highway, a real vehicle experiment was carried out in a highway tunnel with a radius of 255m on the horizontal curve of the national and provincial trunk lines in Yunnan province. Using the Dikablis Professional Eye Movement System and taking the pupil area change speed as an index, the difference of pupil change was compared, and the influence of different vehicle types on visual load and driving safety was analyzed.The results show that the average speed of pupil area change of large truck drivers is significantly faster and the fluctuation range is smaller than that of small bus drivers. Peak of pupil change rate of drivers of large trucks and small buses are located at 0~10m and 5~15m respectively. The change rate of pupil area of the large truck and the passenger car will fluctuate when the tunnel exit is visible behind the entrance section, and the change speed of drivers of large trucks after the peak value of pupil change is more discrete. The research results show that the dark adaptation points of large truck drivers are closer to the entrance of the tunnel, and there is more serious visual load and the driving safety is poor when driving at the entrance of the tunnel.
