标志视认性研究中的主观评价

人对道路交通标志的视认性研究是一个涉及多种学科的交叉课题,因此,通常的研究手段和方法不能完全的满足科研的需求。本文在探讨、介绍了人眼视觉系统的结构,归纳、总结了静态、动态视觉的基本特性的基础上,针对试验仪器在标志视认性客观评价上的局限以及人的主观心理作用在视认过程中的影响,制定了几套以道路交通标志上汉字笔画粗细为研究对象的主观评价试验,并得出了一些值得进一步探究的结论。

Subjective Evaluation in Study of Traffic Sign Visibility

Study on road traffic sign visibility is considered as interdisciplinary science,therefore,ordinary means and methods cannot fully meet the research needs.The human visual system's structure is introduced and the static and dynamic visual characteristics are summarized.Several subjective evaluation tests for thickness of Chinese character strokes are designed to make up for the limitations of test equipment applied in the test and the subjective psychology impact on the traffic signs visibihty.Some conclusions worth further study are summed up.
