摘要： 为研究公路视错觉减速标线的横向宽度对驾驶人瞳孔变化的影响，以梳齿形减速标线为例，横向宽度选择20~50 cm，通过对15名驾驶人进行室内仿真试验，采用瞳孔面积变化率作为评 价公路视错觉减速标线的横向宽度安全舒适性的指标，建立了两者的回归模型。结果表明：运行速度为80 km/h的路段，随着标线横向宽度增大，驾驶人紧张程度愈加严重，瞳孔面积变化率绝 对值越大。以瞳孔面积变化率20%作为表征驾驶人驾驶紧张程度和安全舒适性的阈值，将其代入逻辑回归模型进行计算，得出减速标线横向宽度以44 cm为宜。在此条件下，以40~120 km/h的速 度行驶进行第2组试验，随着运行速度增加，驾驶员视野变窄且视力下降，此时驾驶人的紧张感变强，瞳孔面积变化率增大。

Abstract: Aiming at researching the effect of optical illusion deceleration marking transverse widths on the change of pupil of drivers, the case of comb-shaped deceleration marking was taken as an example and 15 drivers were chosen out for the indoor simulation test, which selected the transverse width was from 20 cm to 50 cm. The changing rate of pupil area was selected as the evaluation index to evaluate the driving safety and comfort of the transverse width of highway optical illusion deceleration marking and the regression models of both were established. The results show that as the transverse widths of marking increase, the drivers feel more nervous and the absolute value of pupil change rate is larger at the section of the road with the speed limit of 80 km/h. The changing rate of pupil area (20%) is used as the threshold to describe divers’ driving tension degree, safety and comfort. The changing rate of pupil area is put in the logistic regression model for calculation and the transverse width of appropriate deceleration marking is 44 cm. Based on the above condition, the second test was carried out with the driving speed from 40 km/h to 120 km/h. And the results indicate that as the driving speed increases, the driver’s visual field is narrowed and the visual acuity is decreased, therefore, the tension of the driver is stronger and the change of pupil area is increased.

Key words: traffic and transportation engineering, changing rate of pupil area, optical illusion deceleration marking, transverse widths
