The main objective of this study is to investigate the factors which affect the roadside signboard cognition during driving. As for the experimental subject to this research, 10 kinds of signboards of suburban roadside shops were studied. The three visible distance of signboards in driving simulator were measured; detectable distance, confirmable distance and legible distance. Also, solid angle and visible angle were analyzed. The effect of color, size, placement of signboard and the difference of luminosity between signboard and its background were shown. The difference of luminosity can be considered when signboard is detected, confirmed and distinguished. Also, wide board placed closer to the road is effective at confirming.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
