摘要
以标志视认过程分析为基础,基于驾驶员认知特性推导了汉字指路标志字高模型,通过大量特殊设计的室内模拟试验和室外实际驾驶试验,以当前我国驾驶员认知特点和交通环境特点为基础,确定了模型中的关键参数。经实车试验验证,该模型符合中国驾驶员对汉字标志的认知习惯,模型计算结果与实车试验结果具有较高吻合性。
A new Chinese character height model for traffic guide signs was developed based on the process analysis of guide sign reading and the perceive characteristics of Chinese drivers.The key parameters of the model were got by some special designed simulations and driving tests based on the perceive characteristics of Chinese drivers and the characteristics of traffic environment. The verifying test shows that the new model well assorts with the perceive characteristics of Chinese drivers.The Chinese character height of guide sign which was got by the model has a good consistent with the test result.
