Evaluation of Curve Delineation Signs on Rural Highways
Jennings, Barton E.

Year: 1983
VTRC No.: 84-R16
Abstract: 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 we-re taken as drivers' responses to the systems. The study showed that drivers react most favorably to chevron signs on sharp curves > 7 degrees and to standard delineators on curves < 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.
