Roadway Shoulder Treatments Rumble Strips

John Huang, Ph.D., PE and John Poullain, PE

This three-hour online course discusses the design and practices used for roadway shoulder rumble strips (SRS). Course topics include the research, past and ongoing, effectiveness, advantages, disadvantages, and benefits for various types of pavement and roadways. The types, designs and dimensions, guidelines for best applications and installation in new and existing roadways are also covered. State policies and practices are reviewed. One-third of all traffic fatalities is caused by run-off-road (ROR) crashes and two-thirds of these crashes occur in rural areas. Many drivers are falling asleep because of fatigue or alcohol or inattention. Shoulder rumble strips (SRS) effectively alert drivers who are running off the roadway by causing a sudden rumbling sound and vibration of the vehicle. Rumble strips are also used to warn drivers of road changes in order to slow for toll plazas, to change lanes for work zones around a curve or to slow for a curve or traffic signals.

Among the topics covered:

History and development of shoulder rumble strips.
Past and ongoing research.
Areas of concern, which require further research.
Types of rumble strips, and improvements in roadway safety.
Construction in pavements and/or shoulders.
How SRS alert drivers for roadway changes.
Benefits and disadvantages.
Survey of State policies and practices.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
