Roadway Shoulder Treatments – Rumble Strips
John Poullain, P.E.
Course Outline
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.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
Learning Objective
At the conclusion of this course, the student will have covered these topics on SRS:
Intended Audience
This course is intended for civil engineers and transportation design engineers.
Benefit to Attendees
The student will become familiar with the design and practices used for roadway shoulder rumble strips (SRS).
Course Introduction
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.
Course Content
The course is based on Parts 1 and 2 of the US DOT Federal Highway Administration publication, “Shoulder Treatments - Rumble Strips (Milled SRS, Rolled SRS)”, (2000 Edition, 66 pages), PDF file.

Course Summary
This course should serve as a guide to assist engineers in understanding the effectiveness, benefits, placement and types of SRS. Best applications and installation in new and existing roadways are discussed. This course should serve as a guide for designing and selecting appropriate SRS for type of roadway pavement and usage.
