基于驾驶员眼动特征的蓄能荧光标线诱导特性及设置方法

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,采集了20名驾驶员的眼动数据,定量分析了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。最后,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,当辉度值为3坎德拉每平方米(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9m效果最佳。

Research on Inducing Characteristics and Setting Method of Energy Storage Fluorescent Marking Based on Driver"s Eye Movement Characteristics

In order to study the visibility of fluorescent markings for active road illumination, UC-win /Road software was used to simulate the highway fluorescent markings, and the eye movement data of 20 drivers was collected to quantitatively analyze the width and layout of different marking lines. Next, the law of the influence of the visibility of the fluorescent marking on the proportion of the driver"s fixation point and the rate of change of the pupil area. Finally, the simulation results are verified by the outdoor real vehicle experiment. The results show that the scheme with the line width of the straight line segment is 100% is the best solution; the luminance value is 3 candela per square meter (cd/m2), the most economical; the curve road marking is applied outside the lane edge line and the spacing is 9m works best.
