DELINEATION OF STOP-SIGN APPROACHES
The objective of the study was to use new types of delineation at a stop approach to determine if drivers could be made more aware of the "Stop" situation ahead. The treatments involved post delineators, raised markers, and transverse striping placed at various spacings in advance of the "Stop" signs. Speeds were measured 200 feet (61 m) and 1,200 feet (366 m) in advance of the "Stop" sign. Brakelight distances were also recorded. The various delineations provided significant reductions in speeds. Post delineators in combination with transverse stripes were the most effective. No significant difference was found between results obtained with geometric and constant-rate-of-advancement (one per second) spacing; however, both patterns were better than a constant spacing. For rural sites, the length of roadway marked should be approximately 1,200 feet (366 m).
