摘要
为研究不同车型和转向条件下山区公路小半径光学长隧道驾驶人的注视转移特性,选取小汽车和大货车在云南山区隧道开展实车实验研究。将公路隧道按光学长隧道特点分成接近段、入口段和出口段3段,使用眼动仪分别采集了实车实验中10名驾驶人的眼动数据。将驾驶人注视位置划分为5个区域并统计各区域注视点频率,然后运用马尔可夫链分析不同车型和转向条件下驾驶人的注视转移特性,并用双因素方差分析了车型、隧道路段、转向对注视分布的影响。结果表明,小汽车和大货车驾驶人对正前方的注视比例均在45%以上。在不同转向和不同的隧道路段,2种车型的驾驶人注视点分布、一步转移概率分布均存在一定的差异,且左转时在不同公路隧道路段的注视策略变化较大,右转时则较为平稳。总体而言,不同车型、不同公路隧道位置、不同的转向均显著影响到驾驶人注视点的分布,以上3个因素两两之间存在一定的交互作用。
In order to investigate drivers′fixation transition features of small-radius optically long tunnel in mountain areas,a car and a truck are selected to carry out field experiments in mountain tunnels in Yunnan.According to features of optically long tunnel,a tunnel is divided into approach section,entrance section,and exit section.The eye-movement data of 10 drivers are collected by eye trackers.In addition,fixation zone of drivers are divided into five sight zones,and fixation frequency of each zone is counted.The Markov chain is used to analyze fixation transition features of drivers with different vehicle types and steering directions.The influences of vehicle type,tunnel segment,and steering directions on fixation distribution are analyzed by two-way ANOVA.The results show that for both car and truck drivers,the proportion of attention paid to the front area of their visual field is more than 45%.With different vehicle types,steering directions,and tunnel segments,there are differences in the fixation distribution and one-step-transition probability.The fixation strategy in different tunnel segments changes greatly when the driver turns left;while it is more stable when turns right.In general,different vehicles,tunnel segments,and steering directions all have significant effects on the drivers′fixation distribution,and they certainly interact with each other.
