Miles Hunsinger

In 2008 Michigan Department Transportation began a project to mill 5,700
miles of center line rumble strips on selected Michigan Trunk lines at a
total cost of approximately $8 million. The purpose of the study was to
assess the impact of center line rumble strips on the number of head on and
sideswipe collisions in the state of Michigan. The data for this study were
obtained from Michigan Traffic Crash Facts and Michigan Department
Transportation for 2004 through 2009. The results indicate a significant
decrease in head on and sideswipe collisions after installation of center
line rumble strips.
