Abstract

Centerline rumble strips are placed between opposing lanes of traffic in "no passing" zones to alert drivers that they have crossed over into the path of oncoming traffic. Although several states and Canadian provinces have experimented with the centerline rumble strips, there is no clear standard for the patterns and dimensions of the strips. This study evaluates 12 different patterns for milled centerline rumble strips to determine the optimal pattern and dimensions for installation on Kansas highways. The patterns were installed at an isolated location for testing and evaluated based on vehicle interior noise level, steering wheel vibration level and exterior noise level. The tested patterns were generated based on the installations of other states. Seven vehicles of various sizes negotiated these rumble strips at varying speeds while the decibel levels at the driver's location, as well as steering wheel vibration, were recorded and analyzed. Based on the results of these tests, two patterns were chosen for further testing in an actual highway setting.
