In recent, the enhancement of guide signs system for expressway were studied. And newly suggested signs in that research show left-right bilingual (Korean/English) configuration of 2 destinations whereas existing signs showed top-bottom configuration. However the new configuration have not been evaluated with discreet examination. In this study, several bilingual configuration designs are developed and evaluated with human factors experiment. Therefore the design with the shortest legibility time were chosen as a best design. As a result, the fact that the change of Korean/English configuration shows different results of the legibility time was confirmed. The guide sign with left-right bilingual (Korean/English) configuration of 2 destinations showed less legibility time than that of the existing signs with top-bottom configuration.
