DESIGNING HUMAN FRIENDLY ROAD INFORMATION BOARD FOR HIGHWAY DRIVERS FROM THE VIEWPOINT OF MULTIPLE SPATIAL FREQUENCY CHANNEL MODEL OF HUMAN VISUAL SYSTEM

This paper addresses the visibility of variable message signs. The authors implement a model of the human visual system in order to establish a more rational method of designing message signs. It is suggested that drivers may be subject to visual adaptation specific to the spatial frequency as well as its orientation. A multiple frequency channel model is used to better understand how humans perceive information signs at different viewing distances.
