Four rural curves were video-taped at night following treatment with six different levels of delineation: no delineation, centerline only, centerline and edgeline, centerline and edgeline and post delineations, centerline and edgeline and raised pavement markers (RPM), and all delineators present. Video presentations were randomly given to 78 subjects. Their response involved distance from target when the curve was detected, direction of the curve and confidence in detection decision.
