Abstract

Many rural, 2-lane roads lack medians, barriers, or other physical measures to separate the travel lanes. As a result, a distinct potential exists for vehicles to cross centerlines, possibly leading to sideswiping or striking oncoming vehicles head-on. In this article, the growing use of centerline rumble strips (CRSs) as a means of warning drivers against crossing over into opposing traffic is detailed. The focus is on an Arizona Department of Transportation (ADOT) pilot program in which CRSs were placed on several stretches of rural highways in northern Arizona. Preliminary results from this study suggest that CRSs can be a cost-effective solution to reduce crashes on rural roads. The ADOT's experiences, observations, and lessons learned from this research are also provided.
