【摘要】：现有的交通警告标志辨识度研究未考虑选项心理暗示与辨认反应,为弥补因此造成的不足,将改进的模糊问卷调查法与基于E-Prime试验系统的试验研究相结合,对国标GB 5768—2009《道路交通标志和标线》中的62个道路警告标志的辨认错误率与辨认反应时长进行评价,利用数理统计及三级分法找出其中辨识度差的警告类标志,并对部分筛选出的实例提出可能的改进措施和设计方案。结果表明,现有道路交通警告标志中,多股轨道与道路相交、注意分离式道路、到无人看守铁道路口100 m、注意保持车距等25个警告标志(占40.32%)的辨识度较差,其中多股轨道与道路相交、注意分离式道路、到无人看守铁道路口100 m等10个标志(占16.13%)的错误率、反应时长等指标尤为突出,辨识度极差。最后参考国外标志设计方案,对部分道路交通标志进行了改进,试验表明改进后的道路交通警告标志辨识度有了明显提高。
[Abstract]:The existing traffic warning sign identification research did not consider the options and identify psychological reaction, to make up for the inadequate, fuzzy questionnaire improvement and experimental research of E-Prime test system based on the combination of the national standard GB 5768 - 62 road 2009< road traffic signs and markings > in the warning sign identification error identification rate and response time is long evaluation, using mathematical statistics and three division method to find out the identification of bad warning signs, and put forward the improvement measures and design scheme of possible examples of some selected. The results show that the existing road traffic warning signs, multi track and road intersection, pay attention to the separated road unattended railway crossing 100, to m, to keep the distance between vehicles and other 25 warning signs (40.32%) less recognizable, which shares rail and road intersection, pay attention to the separated road, to no one The railway junction 100 m 10 mark (16.13%) error rate, response time and other indicators is particularly prominent, recognition is poor. The final design reference marks on the part of the road traffic signs were improved. Experiments show that the improved road traffic warning sign identification has been significantly improved.

【正文快照】： 0引言道路交通警告标志在所有的道路交通标志中占据了很特殊的位置(设计与设置的特殊性等),其对于交通安全具有至关重要的控制性[1]。虽然道路交通标志和标线的设计与规定屡次改进,但仍然存在部分标志辨识度不高的情况,还需要进一步完善。本文重点研究现有国标GB 5768—2009《
