• 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.
