驾驶员注意力分配定量方法研究

驾驶员在不同的路况环境下存在不同的注意力分配模式,为弄清其分配模式特点,利用露天体育场内作为模拟驾驶环境,并利用眼动设备,记录被试者在直道驾驶任务、弯道驾驶任务、复杂路况驾驶任务等3种路况下的眼动数据,采用划分兴趣区域的方式,把视觉信息源划分为原车道兴趣区域FL(Former Lane)和其他兴趣区域OA(Other Areas)两个兴趣区域,对平均百米注视次数、平均百米注视时间、不同兴趣区域注视次数百分比3个眼动指标在两个兴趣区域内的分布情况进行分析和对比,得出不同路况环境下不同的注意力分配模式来揭示驾驶员驾驶过程中的注意力分配特点。研究结果对于驾驶员驾驶培训侧重点的改进、对于预防交通事故都具有重要意义。

Quantitative Measuring Method for the Allocation of Drivers'Attention

To find out the allocating modes of drivers' attention to different road situation,the data of drivers' eye movements under such 3 kinds of road situations as straight driving,curve driving and complex driving was recorded in a stadium that was taken as the simulation driving environment. Meanwhile,according to drivers' interest area,the visual information sources were divided into the Former Lane of interest and the Other Areas of interest. By analyzing and contrasting the allocation of 3 kinds of eye movement indexes (namely,the average fixation number of per hundred meters,the average fixation time of per hundred meters,and the percentage between different interest areas) in the two interest areas,the different allocation modes of drivers' attention to different road situations were obtained and corresponding allocation features of drivers' attention were revealed. The study is beneficial to the prevention of traffic accidents.
