针对驾驶员驾驶安全舒适性特性,以我国双车道公路不同线形组合路段划分标准为研究对象,引入驾驶员驾驶工作负荷理论和驾驶工作负荷度计算模型,通过对驾驶员在双车道公路不同平曲线半径和纵坡坡度条件下的动态驾驶试验方案设计,采集了36名驾驶员在双车道公路不同平曲线半径和纵坡坡度上行车时的运行速度和心电指标数据;在此基础上通过驾驶员在驾驶过程中眼动视频的分析处理,得到小客车和大货车驾驶员在双车道公路不同平曲线半径和纵坡坡度线形、自由流条件下行驶时的驾驶工作负荷度变化规律,发现不同的平曲线半径和纵坡坡度对驾驶员驾驶工作负荷度的影响不同,并确定了满足驾驶安全舒适性的平曲线半径和纵坡坡度划分阈值,最终提出了基于驾驶工作负荷度的双车道公路不同线形组合路段划分标准。
針對駕駛員駕駛安全舒適性特性,以我國雙車道公路不同線形組閤路段劃分標準為研究對象,引入駕駛員駕駛工作負荷理論和駕駛工作負荷度計算模型,通過對駕駛員在雙車道公路不同平麯線半徑和縱坡坡度條件下的動態駕駛試驗方案設計,採集瞭36名駕駛員在雙車道公路不同平麯線半徑和縱坡坡度上行車時的運行速度和心電指標數據;在此基礎上通過駕駛員在駕駛過程中眼動視頻的分析處理,得到小客車和大貨車駕駛員在雙車道公路不同平麯線半徑和縱坡坡度線形、自由流條件下行駛時的駕駛工作負荷度變化規律,髮現不同的平麯線半徑和縱坡坡度對駕駛員駕駛工作負荷度的影響不同,併確定瞭滿足駕駛安全舒適性的平麯線半徑和縱坡坡度劃分閾值,最終提齣瞭基于駕駛工作負荷度的雙車道公路不同線形組閤路段劃分標準。

In view of driver safety and comfort, this paper researched the classification of various combined alignment section on two-lane highway, and introduced the theory of driving workload and the calculation model of driver workload degree. During the experiment, 36 drivers’ ECG indicator and operating speed data in different two-lane highway horizontal curve radii and longitudinal slopes were collected, and eye movement videos were analyzed. Then, the variation of the driving workload of car and truck drivers on various combined alignment sections with different horizontal curve radius and slope grades on two-lane highway was obtained. It is found that the different horizontal curve radius and slope grades had different effects on the driver workload degree. The divided threshold of horizontal curve radius and slope grade was got, which could meet the driver safety and comfort. In addition, the standard of various combined alignment sections on two-lane highway based on the driver workload degree was classified.
