需要关于驾驶时次要任务的总体频率以及个体差异和情境对分心频率的影响的信息，以了解分心对驾驶行为的影响。49名司机参加了一项基于自然驾驶数据的研究，并分析了驾驶时次要任务的频率。两种方法被用来评估次要任务的相互作用：从CAN的完整数据集（类似于370,000公里）和视频分析的一个选定的子集256行程（类似于20,000公里）的客观数据的分析。结果关于单一的次要任务的持续时间和驾驶时间的比例花在不同的次要任务的报告。当乘客在车内时，选择次要任务（除了与乘客的互动）的参与度降低。此外，据观察，特别苛刻的视觉手动辅助任务，最好是在汽车处于静止状态时进行，并避免在高速公路上行驶时。最后，直接比较了上述两种测量方法，并对未来的分析提出了建议。(C)2014爱思唯尔有限公司版权所有。
Information regarding the overall frequency of secondary tasks while driving, as well as individual differences and situational influence on distraction frequency, is needed to understand the impact of distraction on driving behavior. Forty-nine drivers took part in a study that was based on naturalistic driving data and analyzed the frequency of secondary tasks while driving. Two approaches were used to assess secondary task interaction: the analysis of objective data from CAN for the full data set (similar to 370,000 kin) and video analysis for a selected subset of 256 trips (similar to 20,000 km). Results regarding the duration of single secondary tasks and the proportion of driving time spent on the different secondary tasks are reported. Engagement in select secondary tasks (besides interaction with the passenger) was reduced when a passenger was in the car. Moreover, it was observed that especially demanding visual-manual secondary tasks were preferably performed when the car was at standstill and they were avoided when traveling at high speeds on the highway. In closing, the two measurement approaches mentioned above are directly compared and recommendations for future analyses are suggested. (C) 2014 Elsevier Ltd. All rights reserved.
