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。
In order to make up for the deficiency caused by this, the existing traffic warning sign identification research did not consider the option psychology suggestion and recognition reaction. The improved fuzzy questionnaire method was combined with the experimental research based on the E-Prime test system, and the national standard GB 5768- 2009 road traffic signs and marking "62 road warning signs recognition error rate and identification of response time to evaluate the use of mathematical statistics and three-point method to identify the warning signs which are poorly identified, and partial screening The examples presented suggest possible improvements and design options. The results show that, in the existing road traffic warning signs, the multi-track intersects with the road, paying attention to the identification of 25 warning signs (40.32%), such as separated road, 100 m to the unmanned railway crossing, The multi-strand orbit intersects with the road, and the attention is paid to the error rate and response time of 10 signs (16.13%) such as detached roads to the 100-meter unmanned railway crossing, which are particularly prominent and have poor recognition. Finally, referring to the design scheme of the foreign sign, some of the road traffic signs are improved. The tests show that the improved identification of the road traffic signs has been obviously improved.
