接打电话时驾驶人的应激反应特征分析

Analysis of Stress Response Characteristics of Drivers When Answering a Phone Call

为研究驾驶人在接打电话时的应激反应特征的特性,并预防由分心驾驶时带来的交通事故,开展不同场景下的模拟实验。利用驾驶模拟器仿真平台模拟城市复杂路线和高速公路等应激场景,并使用Facelab5眼动仪对接打电话时驾驶人的眼动和驾驶行为进行了记录,分析了接打电话时驾驶人的眼动和驾驶行为及其表征参数。结果表明:驾驶人在驾驶车辆过程中接打电话会导致其在水平方向与垂直方向注视范围集中,注视面积变小,可获取的道路信息明显减少;同时,在城市道路中对加速踏板的控制精度下降,提高了驾驶风险,交通事故率升高。

For the study of drivers on the characteristics of the stress response characteristics of the phone calls,and prevent traffic accidents caused by distracted while driving,to carry out the simulation experiments under different scenarios using a driving simulator simulation platform to simulate urban complex line and highway stress scenario,and use when docking Facelab5 eye-movement apparatus called driver's eye movement and driving records,answer the phone when driving is analyzed the person's eye movement and driving behavior and characterization parameters.The results show that when a driver is talking on the phone,he/she will focus his/her gaze in both horizontal and vertical directions,and the gaze area will become smaller,and the available road information will be significantly reduced.At the same time,the control accuracy of the accelerator pedal in urban roads decreases,thus increasing the driving risk and increasing the traffic accident rate.
