模拟驾驶环境下注意力评估系统设计与实现

Design and Implementation of Attention Evaluation System Under Driving Simulation Environment

摘要:

为研究注意力对安全驾驶的影响,搭建了一套模拟驾驶系统来监控驾驶员的脑电注意力水平；设计了一个实验范式,采集了3个被试的十八次实验数据并进行违规脑电信息的统计分析和评估；,结果表明:驾驶员注意力低水平与交通违规具有明显的相关性；违规驾驶的注意力指标与被试个体特征有关,并且具有具有较好的重现性；驾驶员交通违规的低水平阈值可以通过本模拟环境来测量,这对安全驾驶和事故风险控制具有积极的意义。

Abstract:

In order to study the influence of attention on safe driving, a driving simulation environment is established to monitor the driver's EEG attention level. A experimental paradigm is designed to record the eighteen trials of the three subject's and the traffic violations events statistical results are analyzed and evaluated. The experimental result shows that the driver's lower attention has obvious relevance with traffic violations. The attention level index is associated with individual characteristics and has well reproducibility. The threshold of driver's low attention level of traffic violations can be measured by the simulation environment, which has positive significance on safe driving and accident risk control.
