The three post-mounted delineator systems currently used in the state of 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 drivers' responses to the systems. The study showed that drivers react most favorably to chevron signs on sharp curves and to standard delineators on curves less than 7 degrees. It is suggested that state-wide use of delineators based on these findings will improve the safety and uniformity in delineation on the rural highway system.
