About the research

This study examined the effect of rumble strips on traffic speeds along the northbound and southbound directions of US 65 in Springfield, Missouri. The results indicate that the rumble strips can be placed in a reasonable amount of time and can remain visible and attached to the pavement for several months. However, the desired reductions in speed and speed variability did not occur. The rumble strips should not be expected to reduce speed or speed variability on multilane highway work zones.
