Rumble Stripe Noise Evaluation
4635
This project conducted a series of noise measurements in response to noise concerns related to the installation of rumble stripes on Trunk Highway 61 being brought forward to the Department. The noise measurements included a fixed number of noise readings in close proximity to locations where noise concerns originated. Additionally, efforts were made to gather data on the isolated additional noise generated from a vehicle driving over the rumble strips. The objective was to produce an objective measurement in order to determine the amount of noise existing under current conditions and identify effective mitigation strategies.

The result of this Contract was a Final Report Document with analysis and recommendations for noise mitigation strategies.

This contract was necessary to assess the level of noise in an area where numerous complaints had been received from concerned citizens regarding newly installed rumble stripes and restored public trust in the agency by mitigating noise issues while maintaining road safety. It was reasonable to use a contract for this project due to the urgency and high visibility of the project work.
