• Abstract:
  The high societal cost of roadway crashes nationwide makes improving highway safety an important ; objective of transportation agencies. Recognizing this, Safety Management Systems (SMS) have been ; required by the Federal Highway Administration (FHWA) to encourage states to pursue and promote ; safety and accident investigations. In 2006, the Wyoming Department of Transportation (WYDOT) SMS ; Committee organized an effort to reduce the number of fatal and serious injury crashes on Wyoming ; roadways. A plan was published in a formal document known as the Wyoming State Highway Safety ; Plan (WSHSP). When developing the WSHSP, the WYDOT SMS Committee recognized four main ; emphasis areas: roadway departure crashes, use of safety restraints, impaired driving, and speeding. ; While each one of the four emphasis areas plays an important role in the overall reduction of fatal and ; serious injury crashes statewide, this research focuses primarily on roadway departure crashes. This ; research study summarizes the effectiveness of the WSHSP on crash severity statewide. This is done by ; analyzing crash severity on geometric conditions statewide, as well as the effectiveness of two types of ; safety devices installed on selected roadway sections: shoulder rumble strips and cable median barriers.
