About the research


Work-zone safety is a persistent problem that requires an effective suite of tools that can be applied to constantly varying conditions. The Federal Highway Administration (FHWA) summarizes the severity of the problem by noting that during the past five years in work-zone crashes more than:
The objective of this research is to quantify the impact of using temporary rumble strips within the advanced warning section of a work zone to evaluate both safety and operational aspects including the following: driver braking, change in speed, change in speed compliance, change in lane crossover or going around the rumbles, physical movement of the rumble strips from their initial placement, and tracking of work-zone crashes.
This research will support state DOTs, local agencies, and contractors in preventing work-zone intrusions and rear-end crashes. In addition, this effort supports the MAP-21 emphasis area on safety within the work zone.
