【摘要】：内蒙古草原分布广阔,已建、在建道路都不可避免要穿越草原。在草原道路上交通事故时有发生,大多数事故是由于驾驶员的疏忽大意或操作失误导致,也可以说是驾驶员在行车时采取的驾驶行为不符合交通任务的需求导致。因此,本文对草原道路行车时产生的驾驶行为进行研究,在进行合理的实验设计后,进行了实车驾驶实验。统计并分析了五名驾驶员的头部、手臂及其他部位驾驶行为。结合驾驶员实验前后的主观问卷调查,采用心率增长率和心率变异指标LF/HF与驾驶行为进行对比分析。通过分析发现一些有经验驾驶员的驾驶行为分配比较均衡,相反一些年轻无经验驾驶员的驾驶行为分配不太均衡,各部位驾驶行为出现过多或过少现象。研究还发现驾驶员的驾驶行为与心电指标的关联性较高,当驾驶员的驾驶行为次数增加或减少时,心率变异指标LF/HF会出现较大波动,心率增长率也会出现相应的升高或降低。根据驾驶行为主客观评价结果,对内蒙古草原道路行车时出现的一些不安全驾驶行为,给出合理建议。
[Abstract]:Inner Mongolia grasslands are widely distributed, have been built, the road under construction is inevitable to cross the grassland. Traffic accidents occur from time to time on the grasslands. Most accidents are caused by drivers' carelessness or operational errors. It can also be said that drivers' driving behavior does not meet the needs of traffic tasks. Therefore, the driving behavior of steppe road is studied in this paper. After reasonable experimental design, the real driving experiment is carried out. The driving behavior of five drivers in head, arm and other parts was analyzed. Combined with subjective questionnaire of drivers before and after the experiment, heart rate growth rate and heart rate variability (LF/HF) were compared with driving behavior. It is found that the distribution of driving behavior of some experienced drivers is more balanced, while that of some young and inexperienced drivers is not balanced, and the driving behavior of various parts appears too much or too little. It is also found that the driver's driving behavior is highly correlated with the ECG index. When the driver's driving behavior increases or decreases, the HRV LF/HF will fluctuate greatly, and the heart rate growth rate will increase or decrease accordingly. According to the results of subjective and objective evaluation of driving behavior, reasonable suggestions are given for some unsafe driving behaviors that occur when driving on grasslands in Inner Mongolia.
