摘要: 为研究毗邻互通立交特长隧道的运行特性和驾驶行为变化规律,选取10名驾驶员在雅康高速公路二郎山隧道进行实车实验,利用Tobii眼动仪、前向碰撞预警系统Mobileye及Cirelet单导脑电系统等仪器,采集真实交通状态下车辆位置、时间、行驶速度、驾驶员瞳孔直径及专注度等数据,划分毗邻互通立交特长隧道特征区,给出二郎山隧道入口前和毗邻互通立交分流点段的行驶速度和瞳孔直径分布特性和变化曲线,建立二郎山隧道进出口区瞳孔直径线性模型,并评价洞内景观带专注度等级,分析定向变道影响点至互通立交分流点驾驶行为规律。实验结果表明,设置洞内景观带可以缓解驾驶员视觉疲劳,且景观带国旗区效果优于星空区。驾驶员看到定向变 道标线白色虚线后,瞳孔直径逐渐减小至3.65 mm,行驶速度维持在71~73 km·h-1 ,在变道操作期的视觉负荷和心理紧张度最大,在条件观察期专注度最高,驾驶员需要根据等待可插车间隙迅速反馈和进行是否变道等操作。

Abstract: To analyze the operation characteristics and driving behaviors of the super-long tunnel adjacent to interchanges, this study carried out the real vehicle test with 10 drivers operating in the Erlangshan Tunnel of the Yakang Expressway in China. The data of vehicle position, time, driving speed, and driver's pupil diameter and concentration were selected using Tobii eye tracker, Mobileye forward collision warning system, and Cirelet singleguide EEG system under real traffic conditions. The feature zones of the super-long tunnels adjacent to interchanges are divided. Given the distribution characteristics and variation curves of the driving speed and pupil diameter in front of the entrance of the Erlang Mountain Tunnel and adjacent interchange diversion points, a linear model of pupil diameter in the entrance and exit area of Erlangshan Tunnel was established, and the concentration level of the landscape belt in the tunnel was evaluated. The driving behavior changes from the directional lane change influence point to the interchange diversion point were analyzed. The results show that the landscape belt in the cave can relieve the driver's visual fatigue, and the effect of the national flag area of the scenery belt is better than that of the starry sky area. When the driver sees the white dashed line of directional lane change marking, the pupil diameter gradually decreases to 3.65 mm, and the driving speed is maintained at 71~73 km·h-1 . During the lane change operation period, the visual load and psychological tension are the highest, and the concentration is the highest in the conditional observation period. The driver needs to give rapid feedback and conduct lane change or not according to the acceptance gap.
