摘　　要：为了研究公路主动发光的荧光标线视认性,利用UC-win/Road软件对公路荧光标线进行仿真模拟,采集20名驾驶员的眼动数据,定量分析不同标线宽度和布设方式下,荧光标线视认性对驾驶员注视点占比和瞳孔面积变化率影响的规律,通过室外实车实验的方式对仿真结果进行验证。结果表明:直线路段标线宽度为100%的方案是最佳方案,当辉度为3 cd/m^2时,为最经济方案;曲线路段标线施划在车道边缘线外侧且间距为9 m效果最佳。To study the visibility of fluorescent markings for active road illumination,the UC-win/Road software was used to simulate the highway fluorescent markings,and the eye movement data of 20 drivers were collected to quantitatively analyze the width and layout of different marking lines.Next,the influence of the visibility of fluorescent marking on the driver’s visual range and the change of the pupil area were examined.Finally,the simulation results were verified in an outdoor real vehicle experiment.Results show that the best design for a straight road segment was 100%in luminance at 3 cd/m^2,and for curve road section,it shall be marked on the shoulder margin in space of 9 m.
