摘　　要：由于GB5768-2009的规定比较模糊,我国路面限速标记的设置条件和尺寸比较混乱,不仅没有起到限制驾驶人行车速度的目的,也带来一定的安全隐患。通过模拟仿真技术结合问卷调查和实验研究,对分别使用数字和图案的路面限速标记的效果、路面图案限速标记的设置尺寸进行了探讨。结果发现:(1)相对于数字,多数驾驶人认为采用图案形式的路面限速标记,更容易被他们所理解,也更容易引起他们的注意;(2)无论是高速公路还是二级公路,路面限速标记均宜采用长宽比为3∶1的图案,二级公路的宽度宜采用2.4m左右,高速公路的宽度宜采用2.7m左右。As GB5768--2009 could not give clear instructions on how to set speed limit markings on the road and what sizes to use, design engineers are confused, and many different road markings could make traffic much more dangerous. Based on the traffic simulation technology, questionnaire survey, and some experimental study, this paper explores the difference of figure and graphic road marking, as well as the size of the graphic road marking. The results showed that： （1） compared with the figure road marking, graphic road marking can attract drivers＇ attention much more easily; （2） both expressway and secondary highway, the road speed limit marking should adopt the pattern of length/width ratio is 3 ： 1, and the width of marking should be about 2.4 m for secondary road, while that should be around 2.7 m for expressway.
