• Abstract:
  The Federal Highway Administration (FHWA) organized 37 States to participate in the FHWA Evaluation of Low-Cost Safety Improvements Pooled Fund Study as part of its strategic highway safety plan support effort. The purpose of the study was to evaluate the safety effectiveness of several low-cost safety improvement strategies through scientifically rigorous crash-based studies. One of the strategies evaluated for this study is the combination of centerline and shoulder rumble strips. This strategy is intended to reduce the frequency of crashes by alerting drivers that they are about to leave the travelled lane. While research into the performance of shoulder and centerline rumble strips applied separately has been conducted, the combination of shoulder and centerline rumble strips is still relatively rare and has not been studied to the same degree. This study sought to fill this knowledge gap.
