• Abstract:
  In 2008, Michigan launched a major systemwide installation of both ; centerline and shoulder rumble strips on 5,400 miles of its rural, ; non-freeway highway system. This unprecedented initiative was ; accomplished during a three-year period ending in 2010. A two-phase ; evaluation study focused on the crash reduction benefits of centerline ; rumble strips, which have not been studied as extensively as shoulder ; rumble strips. The just-completed Phase 2 study included an analysis of ; before-and-after crash data, a cost-benefit study, surveys of drivers and ; MDOT personnel, and guidelines for local road agency implementation of ; rumble strips.
