指路标志信息量与认知性关系研究

Relationship Between Information Quantum of Traffic Guide Sign and Its Cognition

研究以眼动仪EMR-8B为主要的实验仪器,以大量的室内实验为研究手段。通过记录试者视点在室内模拟影像中播放的指路标志上的停留时间,从而得到不同信息量指路标志的认知时间,建立了标志信息量与认知时间的量化关系。在汉字字数少于17字,路名数少于6个时,认知时间增长趋势相对均匀,超过这一标准增长趋势明显;在指路标志的版面信息量设计时,汉字字数应以少于17字、路名数少于6个为宜。

Resorting to large numbers of indoor experiments applying EMR-8B as experimental apparatus, and getting the cognition time of traffic signs with different information quantum through recording the residence time of the object＇ s eye mark on traffic signs played by projection, the paper develops the quantitive relationship between the information quantum of traffic guide sign and its cognition time. The increase tendency of cognition time can keep balance with the characters of road name under 17 and the number of road names under 6. Traffic guide sign designing should accord with such norm （characters of road name under 17 and number of road name under 6） .
