中文摘要
      研究基于上海市自然驾驶项目,共计提取了296个驾驶人使用手机的行为样本,并基于动态时窗构建了表征驾驶人控制行为的特征指标,针对使用手机的5种操作行为:拨打、接听、通话、挂断和查看信息,分别分析了各操作过程中驾驶人纵向、横向控制活动的强弱情况,执行控制操作的灵敏程度以及车辆控制状态的稳定性.研究表明驾驶过程中使用手机的部分操作会导致驾驶人控制活动有所减弱,控制操作更加迟缓,且大多数分心操作对纵向控制稳定性产生了显著影响.这些发现有助于更好地了解驾驶人使用手机时的自然行为变化,为交通安全管控提供指引.
英文摘要
      There is a clear relationship between driving behavior and crash risk, with using mobiles during driving one of the key factors related to crash risk and severity. Towards the limitation of driving simulators in an unnatural setting, 296 samples of mobile phone operations during driving were extracted in Shanghai naturalistic driving study data, and the process of using mobile phones was divided into five operations: dialing, answering, talking and listening, hanging up and viewing. The study respectively analyzed the strength of driver’s control activities, the sensitivity of the control operation and the stability of the control state during each operation. Studies have shown that some operations will lead to a decrease in driver’s control activities and affect the stability of vertical control. These findings help develop more reasonable traffic safety management measures.
