摘　　要：驾驶员的注意力分配对行车安全至关重要。目前基于驾驶员注意力分配的研究大多是基于定性的,从定性和定量两个角度,结合实际道路场景,借助眼动仪进行实车试验,记录并统计驾驶员在不同道路环境及驾驶环境[直行路段、掉头路段、人行横道(非路口)路段、超车、起步、靠边停车]下眼动数据,分析其注视点、注视时间及注视区域的特性;并得出在不同道路环境及驾驶环境下注意力的分配模式,揭示驾驶员在驾驶过程中的注意力分配特点。研究结果对驾驶员安全驾驶、车辆辅助系统、无人驾驶系统及驾驶员驾驶培训考核标准的改进有着十分重要的意义。Driver attention allocation is critical to driving safety.Nearly all the existing researches based on driver attention allocation are from qualitative point.From both qualitative and quantitative point,the real vehicle experiment is carried out with the practical road scene using eye tracker.In the experiment,the driver s eye movement data from different road environment and driving condition such as straight road section were the statistic,Uturn section,crosswalk with non-intersection road,overtaking,starting,and parking.Then the characteristics of attention,fixation duration and gaze area were analyzed.Finally the distribution model of attention in different road environment and driving environment was obtained,which reveals the characteristics of attention distribution of drivers during driving.The results are of great significance to the improvement of driver safety driving,vehicle assistance system,unmanned driving system and driver training assessment criteria.
