Rumble Strip Design Analysis to Contribute to Low Exterior Noise and the Durability of Inlaid Stripes

The main goal of the research is for Oregon Department of Transportation (ODOT) to identify an implementable rumble design (strip, stripE, or combination inlaid), which is acceptable in noise output to communities who live close to the highway, but without the rumble losing its safety benefit of alerting drivers when they depart the road. Documentation of rumble strip/stripE designs that meet the aforementioned design criteria will be delivered in the format of a proposed design specification for use by ODOT and other road authorities. The combination of traffic situation, road condition and driver variability make it very challenging to develop robust rumble design alerting devices. Through conducting the research in this project, a list of rumble geometry with predicted performance will be developed for ODOT to make decisions from. Moreover, three extensive literature reviews will be done. The first literature review will be on existing shoulder and center rumble strip designs to compare emerging sinusoidal designs against conventional designs. The second literature review will examine required noise levels associated for safety and the maximum/minimum range for drivers and potential public members close to the roadway. Moreover, to corroborate the vehicle speeds chosen in the project, the research team will look into accident reports that involve rumble strips to formulate a range of plausible speeds over rumble strips. The third literature review will focus on existing physics-based models that describe the noise generation process when tires roll over road surfaces. Numerical modeling using a Finite Element Method (FEM) will be conducted to simulate noise generation given various inputs. This modeling will be verified against existing published measurement data, including some alternative project data completed for ODOT.
