EVALUATION OF CURVE DELINEATION SIGNS

The three post-mounted delineator systems currently used in Virginia were tested at five sites for their effectiveness in controlling run-off-the-road accidents. The changes in speed and lateral placement noted with the systems in place were taken as driver responses to the systems. The study indicated that drivers react most favorably to chevron signs on sharp curves greater than or equal to 7 degrees and to standard delineators on curves less than 7 degrees. It is suggested that statewide use of delineators based on these findings will improve the safety and uniformity in delineation on the rural highway system.
