摘要: Although traffic deaths are caused by an array of factors, in the United States more than half of all roadway fatalities are caused by roadway departures (FHWA 2006). In 2003, there were 25,562 roadway departure fatalities, accounting for 55 percent of all roadway fatalities in the United States. Roadway departure includes run-off-the-road (ROR) and head-on fatalities. In 2003, more than 16,700 people died in ROR crashes (39 percent of all roadway fatalities), and head-on crashes represented 12 percent of all fatal crashes (FHWA 2006). On average, one roadway departure fatality crash occurred every 23 minutes. An average of one roadway departure injury crash occurred every 43 seconds (FHWA 2006). In short, roadway departures are a significant and serious problem in the United States. MDOT through the Traffic Engineering Division is committed to improve Mississippi highway safety. MDOT has invested valuable resources to implement a series of safety improvement programs such as the Rumble Stripes program. Unfortunately, there is a dearth of studies documenting the impact of Rumble Stripes on roadway safety. Thus, this study summarizes an effort funded by the MDOT to quantitatively document the safety impact of rumble stripes in Mississippi. Both descriptive and inferential statistics were used to determine the safety impact. Thirteen road segments were selected to collect and process the data for this research project. The results presented in this paper intend to serve as a sample of the impact of this type of programs. Furthermore, other projects and other departments of transportations might benefit with implementing the analysis presented here as an avenue to quantify the safety impact of rumble stripes an other safety programs.
