摘　　要：为确定高速公路互通立交出口前并设的多块指路标志的组合中合理的信息数量,基于认知心理学的相关理论,分别开展室内静态模拟试验和室外动态实车试验,得到组合式指路标志中不同的信息数量所对应的认知时间。通过回归分析,建立组合式指路标志信息数量与认知时间的计算模型。试验结果表明:认知时间和路名信息数量并没有显著的相关性;地名信息数量越多使得驾驶员的认知时间越长,当地名信息数量超过8个时,认知时间出现明显变化;在信息数量相等的条件下,标志版面数量对认知时间没有显著影响。建议高速公路组合式指路标志的地名信息数量以不超过8个为宜。In order to find the reasonable information load value of a guide sign array with a combined form setting up in front of freeway interchange exit,a static simulation experiment was performed in laboratory,and an on-road experiment was performed in test ground,based on theory of cognitive psychology.The reaction times of combined guide signs with different information loads were obtained through these experiments. A calculation model was built based on regression analysis for calculating the reaction time according to the information load. The result show that there is no significant correlation between reaction time and road names,that more place names the combined guide signs have,the longer reaction time the drivers need,that under conditions of equal information load,the number of signs in a sign array has no significant impact on reaction time,and that reasonable information load value of place names is 8.
