驾驶时间对营运驾驶员驾驶能力影响的试验研究

针对影响交通安全的疲劳驾驶问题,以公路客运行业的营运驾驶员为研究对象,应用人机工程学和试验心理学的理论方法按驾驶时间的不同设计了区组对比的试验方案,并用试验仪器现场采集了99个样本的试验数据,利用F检验和H检验等统计学方法分析了驾驶时间对驾驶员驾驶能力的影响。结果表明:驾驶时间在8~12 h之间,驾驶员的反应能力和注意能力会显著降低,而驾驶员的感知能力和操作能力的降低不明显;驾驶员的主观疲劳感受随驾驶时间的变化不明显。

Experimental Research on the Impact of Driving Time on Commercial Driver's Driving Ability

An investigation focusing on fatigue driving in road safety was performed using the methodologies of human factors and experimental psychology.Commercial drivers of highway passenger transport were chosen as the study objects and experiment of a block design is schemed according to the difference in driving time.After the collection of 99 driver's experiment data,the influence of driving time on driver's driving ability was analyzed using F and H test in statistics.The results showed that after 8 to 12 hours of driving,degradation of driver's ability of reaction and concentration was significant,but degradation of driver's ability of cognition and operation was not significant;the change of driver's feeling of fatigue was not significant as driving time increased.
