DELINEATION AS ROAD SIGNING: A STUDY OF VISUAL CUES ON RURAL ROADS AT NIGHT

Formal delineation schemes on rural roads need to supply several types of information to the driver under night conditions. He needs longer-term delineation information or reasonable preview in order to plan ahead on approach to curves. The experiment reported explored the effect of various delineation schemes, road contour, distance to the curve, and the curve direction of turn under two reaction time instructional conditions. The results demonstrated that road-side post delineation provides effective information of this type, while no benefit was found from edgelining. Right-hand curves were responded to faster and were more easily detected than left-handers. (Vehicles in Australia travel on the left. U.S. readers may prefer to read "right" for "left", and vice versa.) Serveral interesting interactions were found between the factors studied. (SRIS)
