手机导航方式对驾驶行为的影响研究

Research on influences of mobile navigation modes on driving behavior

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。

In order to study the influences of mobile navigation on driving behaviors,simulated driving experiments and the eye movement experiments were designed and carried out,then the visual parameters and the vehicle driving state parameters were obtained. Through the variance and the significance analysis,differences in driving behavior under different mobile phone navigation modes were explored. The results indicate that all mobile phone navigation modes have a certain impact on driving behavior,resulting in distracted driving to a degree as a function of the mode,that hand-held mobile phone navigation reduces most significantly the drivers＇ attention to both the front area and the left side,in this navigation mode,the increase in the average glancing number is also the largest and the driver has the most frequent search for the visual area,that the drivers maintain stability by reducing the speed,the lagest decline extent in speed can be attributed to hand-held phone navigation,and that the vehicle ＇ s longitudinal velocity standard deviation is more concentrated when using mobile navigation,and the driver ＇ s control of the vehicle is strengthened.
