【摘要】：为研究驾驶员驾驶时使用不同手机导航方式对驾驶行为的影响,开展模拟驾驶试验,利用眼动仪获取4个场景下车辆行驶状态和驾驶人视觉参数;通过均值比较,方差和显著性分析,探究不同手机导航方式下驾驶行为存在的差异。结果表明:不同手机导航方式均造成驾驶分心,但分心程度不同;手持手机导航使驾驶人对前方和左侧区域的关注下降最为显著;使用导航时,驾驶人一般通过降低车速来减少分心带来的潜在风险,其中手持手机导航降低幅度最大;使用手机导航时,车辆纵向速度标准差更加集中,说明此时驾驶人对于车辆的控制变强。
[Abstract]:In order to study the influence of different mobile phone navigation modes on driving behavior, a simulated driving test was carried out, and the vehicle driving state and driver visual parameters were obtained by using eye movement instrument, and the mean values were compared. The variance and significance were analyzed to explore the differences of driving behavior under different mobile phone navigation modes. The results showed that different mobile phone navigation modes caused driving distractions, but the distractions were different. Handheld mobile phone navigation caused the most significant decrease in the attention of the front and left areas. Drivers generally reduce the potential risk of distraction by slowing down their speed, with handheld navigation reducing the most; using mobile phones, the longitudinal speed standard deviation of the vehicle is more concentrated. This indicates that the driver's control over the vehicle has become stronger.
