摘要: 为了预防重型长途货运汽车驾驶员夜间的驾驶疲劳,在京珠高速公路进行实车试验,采集驾驶员的历时心率数据,并以心率增加率和疲劳综合评价值为指标分析和评价驾驶疲劳情况。结果表明:驾驶仓栅式载货车属于轻级劳动强度,疲劳综合评价值为1.300;而驾驶半挂车属于中级劳动强度,疲劳综合评价值为1.624~1.929。进一步通过安全阈值分析得出,重型货车驾驶员每次连续驾驶的时间不宜超过3.0 h。研究结果为夜间重型货车驾驶员合理安排驾驶时间,有效预防驾驶疲劳提供了参考依据。

Abstract: In order to prevent night driving fatigue of heavy long-distance freight vehicle drivers, a real vehicle test is conducted in the Beijing-Zhuhai Expressway. In the test, heart rate of drivers is collected, and then heart rate increase ratio and fatigue comprehensive assessment value are used to analyze and evaluate driving fatigue. The results show that for the driver driving a stake truck, the workload lies at a light level, fatigue comprehensive assessment value is 1.300. While for the driver driving a semitrailer, the workload lies at an intermediate level, fatigue comprehensive assessment value is 1.624~1.929. Further safety threshold analysis concludes that each continuous driving time for truck drivers should be no more than 30 h.The results provides a reference for drivers to reasonably arrange driving time and effectively prevent driving fatigue.
