为研究新老驾驶人在农村公路复杂环境中的视觉特性,采用眼动仪测量若干被试人员在实际驾驶过程中的视觉生理指标,运用统计学和数据挖掘方法分析新老驾驶人的瞳孔直径、注视特性、扫视特性和追随眼动特性,进而辨析新老驾驶人的驾驶行为特性差异。结果表明,在农村公路复杂道路环境中,新老驾驶人的视觉特性和驾驶行为具有明显差异。新驾驶人的瞳孔直径变化剧烈,表现出长时间注视和注视反馈特性;老驾驶人具有较多短时间注视特性,注视前瞻性和反馈特性都很明显,并且具有追随眼动特性。
In order to study the visual characteristics of old and new drivers in the complex environment of rural roads, the eye movement meter was used to measure the visual physiological indexes of some subjects during actual driving. The pupil diameter of new and old drivers was analyzed by using statistics and data mining methods , Gaze characteristics, glancing characteristics and follow the eye movement characteristics, and then distinguish between new and old drivers of driving behavior differences. The results show that the visual characteristics and driving behavior of new and old drivers are obviously different in the complicated road environment of rural road. The new driver’s pupil diameter changes dramatically, showing long-term gaze and gaze feedback characteristics; older drivers have more short-term gaze characteristics, looking forward and feedback characteristics are obvious, and has to follow the eye movement characteristics.
