为了解驾驶员安全舒适度评价指标(驾驶负荷)在高原公路弯坡路段的变化特征,利用生物反馈仪等相关设备,在海拔大于3 000~5 000 m的高原公路选取符合标准的弯坡路段62段进行行车试验。定量分析了驾驶负荷与海拔、高原公路弯坡路段线形组合值之间的变化关系;并且建立了相关模型。结果表明,驾驶员在高原公路弯坡路段行车过程中,驾驶负荷受到海拔与弯坡路段线形组合值的双重影响;驾驶负荷随着海拔的升高而增大;上下行过程中,驾驶负荷随着弯坡路段线形组合值的增大而增大;在海拔与弯坡路段线形组合值的共同作用下,驾驶负荷变化更加明显,海拔越高、弯坡线形组合值越大,驾驶负荷越大。
In order to understand the changing characteristics of driver safety comfort evaluation index (driving load) on the curved road section of plateau highway, using the relevant equipment such as biofeedback instrument and so on, select the standard curved sections on the plateau highways above 3 000 ~ 5 000 m 62 paragraph for driving test. The relationship between driving load and altitude, the linear combination value of the curved section of the plateau highway is quantitatively analyzed. And the correlation model is established. The results show that the driver’s driving load is affected by the linear combined value of the altitude and the curved road section during the driving process on the curved road section of the plateau; the driving load increases with the elevation; Under the combination of linear combination of elevation and curved section, the driving load changes more obviously. The higher the elevation is, the larger the combined value of curve linear curve and the larger the driving load .
