高速行车状态下驾驶人应激反应能力研究

为减少驾驶人在高速公路行车时因应激反应失误而引发交通事故,基于动力定型理论,开发驾驶人应激反应训练系统并进行仿真实验研究。选用30名被试分别在4个高速公路中典型应激交通场景下进行,运用MP 150实时记录被试人员的心率参数,运用对数回归和相关性分析,研究应激反应能力与训练次数间的定量关系。结果表明:随着训练次数增加,驾驶人应激反应能力增强。驾驶人经过标准规定次数的训练,即可减缓应激状态下的心理紧张,提高应激反应准确性和速度。设计的系统及建立的训练次数标准,满足驾驶人应激反应能力训练需求,可增强驾驶人应激能力,减少此类交通事故发生。

Research on Stress Response Ability of Drivers on The State of High Speed Driving

Based on the theory of driving stress training and impetus customization, driver stress training system was designed to reduce traffic accidents due to drivers＂ lack of stress response ability when driving under the expressway conditions. In the experiment, 30 subjects were selected to attend 4 typical conditions for the virtual simulation expressway driving experiment on the system platform. Heart rate was detected by MP150 simultaneously to indicate variation of stress response ability. Experimental data were disposed of by logistic regression and relativity analysis. The results show that stress response ability was strengthened with the increasing number of training. Trained on different stress driving scenes under urban road condition by training standards, drivers were relaxed and their response accuracy and speed was promoted. Demands of stress response were satisfied by training system and standards. Stress response ability of drivers can be pro- moted and these types of traffic accidents can be redneed efficiently.
