| 摘 要： | 通过对27名典型车型驾驶员在高速公路不同线形条件下的运行速度、生理和心理变化等现场试验数据采集、分析,得到驾驶员安全舒适性评价指标(驾驶工作负荷度)在高速公路不同线形组合路段的变化规律;提出高速公路线形变化引起的车辆运行速度和驾驶工作负荷度变化具有提前性,而并非在道路线形变化点同时发生变化,这种提前现象反映出驾驶员对道路线形条件变化认知和决策的适应特性;提出了基于驾驶工作负荷度变化特性的高速公路不同线形组合路段划分标准。研究结论对道路设计、交通安全设施布设和道路运营管理等理论和实践具有一定的参考价值。

| Abstract: | In this research,typical vehicles(cars and trucks) were chosen for real-vehicle testing with a random sample of 27 drivers.Also,pieces of equipment were employed for real-time measurements of vehicle speed and changing indexes of physiology and psychology.Through analyzing the data of different drivers measured on various combined alignment,the orderliness of driver workload degree was obtained.The change of driver workload degree induced by road alignment was ahead of the change of the expressway alignment... |
