Removable Orange Rumble Strips--KS
Status: Complete
Description: The strips were deployed in advance of a bridge repair project in central Kansas on a two-lane rural road. The construction traffic control utilized a temporary signal to control flow through the single open lane across the bridge, and standard KDOT traffic control was used in advance of the signal, including two sets of asphalt rumble strips, one starting at about 1000-ft in advance of the signal and the other at about 1500-ft. The removable strips were installed 2500-ft in advance of the signal. The thickness of the strips (roughly 1/8-in) was not sufficient to be reliably detected by drivers. However, there was a statistically significant reduction in vehicle speeds after the installation of the strips, suggesting that the orange color of the strips acted as a warning device.
