Research oriented identification of railway passenger station of vision, vision, visual range,con- , trast, and other aspects, observed by more accurate observation of the orientation identification, so as to reduce misunderstanding,read the leak,saving the observer's time. Through field surveys and comparative analyses, using the method of calculation of the visual angle,combined with ergonomic principles,deduces perspective and horizon and perspective and identify the relationship between the size of identity card and the size of the observer to identify brand is directly related to visual range, and watch the identifying information for the best visual angle 30?when in normal view;Ratio of font color and background color,number,small, watching identifies more clearly; Color contrast sensitivity, the higher the draw of character recognition. Guide provides new data based on the design of the badges, in appropriate locations reasonably identifies the direction of the observer can observe more accurately oriented identity, while improving the efficiency of railway passenger station.%目的 研究铁路客运站导向标志的视角、视野、视距、对比度,使观察者更准确地观察导向标志,减少误读、漏读,节省观察者时间.方法 通过实地调查和对比分析,运用视角的计算方法,结合人机工程学原理,推导出视角与视距和视角与标志牌大小的关系.结果 标志牌的大小和观察者到标志牌的视距有直接的关系,观看标志信息牌的最佳视觉角度范围在正常人平视时的30°视锥内;字体颜色与背景颜色的比值:数值越小,观看标志牌越清晰;色彩搭配对比感度越高,得出字符辨认性越大.结论 为导向标示牌的设计提供新的数据依据,在适当的位置设置合理的导向标志,使观察者能更准确地观察导向标志,同时提高了铁路客运站的工作效率.
