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。
By collecting and analyzing the field test data of 27 typical vehicle drivers under different linear conditions of the expressway, the driver safety comfort evaluation index (driving load degree) is obtained in different linear forms of the expressway It is pointed out that the changes of the highway running speed and the driving load degree caused by the linear change of the expressway are advanced rather than changed at the same time. This advance phenomenon reflects the change of the linear condition of the road Cognitive and decision-making, and proposed the criteria for dividing line segments with different linear combination based on the variation of driving load degree. The conclusion of the study is of certain reference value to the theory and practice of road design, traffic safety facilities layout and road operation management.
