Abstract:Lane departure crashes including single-vehicle-run-off-road crashes, opposite direction sideswipe and head-on crashes are considered the most sever
crashes and often dominated by sleep deprivation/fatigue, and distracted driving. According to the Federal Highway Administration, 53 percent of annual
fatal crashes are attributed to lane and road departures. In Wyoming, lane departure crashes comprised 72 percent of all sever crashes for the years 2008 –
2010. While lane departure crashes are mostly driven by drivers‘ errors, reduction of the frequency and severity can be achieved by more forgiving
roadside and specific countermeasures. Rumble strips/stripes are used by many states as a relatively low cost proven safety countermeasure to reduce or
prevent lane departure crashes through providing a vibrotactile and audible warning to inattentive motorists. Although the advantages of rumble strips
were generally found to outweigh the disadvantages, several issues and concerns have been identified regarding the implementation of rumble strips;
noise, maintenance, and the adverse effects on bicyclists and motorcyclists are among the most recognized concerns.
This study demonstrated that despite the fact that rumble strips have been used for many years, there are no standardized practices used in the U.S. A
significant number of states are still working on updating their rumble strips policies; their main goal is to enhance motor vehicle safety while
accommodating all road users to the highest practical extent. The information provided in this report and the companion Expert System that was
developed as part of this study may provide the necessary background for WYDOT and other transportation agencies when it comes to updating or
developing an effective all road users‘ friendly rumble strips policy.
