摘要：	Traffic crashes result in significant life and economic loss and also bring have emotional burden to the society. More than 50% of all fatal crashes and traffic crash fatalities occurred in rural areas. Lane departure crashes are a major type of crashes in terms of crash frequency and injury severity. Lane departure crashes include run-off-the road (ROR), head-on, cross-median, and overturn crashes, and overturn crashes are a major crash type. In New Mexico, 65% of all fatalities and 44.5% of all serious injuries occurring on roadways from 2004 to 2009 involved lane departure. Alcohol, speed, fatigue, and distraction are frequent contributing factors to lane departure crashes. Drivers who are fatigued and/or inattentive at the wheel can understandably veer off the roadway onto the shoulder or even cross the centerline and veer into oncoming traffic, posing the horrific injury outcomes. Additionally, poor visibility of roadway lane shoulders has been identified as one of the leading causes of lane departure crashes during nighttime and inferior weather conditions. Rumble strips have been an effective highway safety countermeasure for inattentive or distracted drivers against potential overturn crashes due to their audible rumbling sound and tactile vibration, especially on rural highways. However, due to infrastructure deterioration that can be attributed to aging, traffic loading, rainfall, and temperature variation, roadway shoulder striping becomes less visible to provide the motorist with adequate information of the edge of the outside driving and lead to an increase in overturn crash occurrence frequencies and severities.
