摘　　要：为研究不同道路监控补光灯对驾驶员眩光的影响程度,挑选10名视力正常受试者夜晚驾车经过城市、郊区、高速3种不同环境路段,使用照度计测量不同路段补光灯及补光灯环境照度,采用Tobii Pro Glasses 2眼动仪获取眼动特征数据,分析驾驶员瞳孔直径变化程度及瞳孔中心位移变化。研究结果表明:驾驶员在不同道路监控补光灯照明刺激下,人眼运动会发生不同程度变化。郊区道路瞳孔直径变化最大可达32%左右,是城市道路及高速道路的3倍左右。郊区道路监控补光灯照度以及补光灯环境照度差距明显,增大驾驶员暗适应时间,在3 s内瞳孔直径未能恢复正常,造成视物不清。同时在郊区道路驾驶员瞳孔中心位置偏移至视角范围为5°~220°的边缘区域远离中央窝区,造成视野模糊。研究结果可为驾驶员夜间安全驾驶提供数据支撑及应对措施。To investigate the influence of glare from different road monitoring supplementary lights on the drivers,10 subjects with normal vision were selected to drive at night through three road sections with different environments including urban,suburban,and highway.The illuminance meters were used to measure the illuminance of supplementary light and environment in different road segments.The eye movement characteristic data were obtained by using the Tobii Pro Glasses 2 eye tracker,and the change in the pupil diameter and pupil center displacement of drivers was analyzed.The results show that under the illumination stimulation of monitoring supplementary lights in different road environments,the eye movement of drivers varies to different degrees.The change of pupil diameter on suburban road can reach up to about 32%,which is about three times those of urban road and highway.There is significant difference in the illuminance between monitoring supplementary light and environment on suburban road,the driver’dark adaptation time increases,and the pupil diameter fails to return to normal within 3 s,resulting in blurred vision.At the same time,the pupil center position of drivers on the suburban road shifts to the edge area with a viewing angle range of 5°to 220°away from the central fossa area,resulting in blurred vision.The research results can provide data support and countermeasures for drivers to drive safely at night.
