本文依托四川雅泸高速公路长大纵坡路段行车安全对策研究项目,开展了针对山区高速公路连续下坡路段驾驶员特性分析,重点阐述了货车驾驶员在连续下坡路段驾驶行为特征问卷调查统计结果,以及车辆在连续下坡路段行驶时驾驶员皮温、脉搏、皮肤导电水平等生理指标的变化趋势,以进一步把握山区高速公路连续下坡路段驾驶员特性。分析结果表明货车驾驶员对于长大下坡的危险意识不够,并且存在相当数量的驾驶员有把下坡误认为是平坡或上坡的经历。在下坡过程中驾驶员生理指标总体呈上升趋势,接近坡底时呈下降趋势,驾驶员在连续下坡路段容易出现紧张情绪。
This paper relies on Sichuan Yalu Expressway Longitudinal section of road safety measures research project carried out for the mountain highway continuous downhill section driver characteristics analysis focused on truck drivers driving characteristics of continuous downhill section of the questionnaire survey results, As well as the trend of physiological indexes such as driver’s skin temperature, pulse rate and skin conduction level when the vehicle runs down a continuous downhill section, so as to further grasp the driver characteristics of the continuous downhill section of mountainous expressway. The analysis showed that truck drivers were not aware of the danger of getting on and off, and there was a significant amount of pilots who mistook for downhill slopes or uphill. During the downhill process, the physiological indexes of pilots showed an overall upward trend, which showed a downward trend when approaching the bottom of the slope. Drivers were prone to tension in the continuous downhill section.
