• Abstract:
  This report focuses on collecting and analyzing external and internal noise levels generated by the modified transverse rumble strips on US-41 that were reconstructed in October 2022. The goal is to enable a comparison with noise levels generated by the previous rumble strips that were constructed in the same location in 2019. This work is organized in three tasks: (1) observe and document the construction of the 2022 transverse rumble strips, (2) collect US-41 traffic flow data as well as external and internal noise levels generated by the 2022 transverse rumble strips, and (3) compare the collected external noise levels generated by the 2022 US-41 rumble strips to those generated by the 2019 US-41 rumble strips that were collected and reported in the related 2021 study. The comparison results demonstrate that the time-equivalent continuous sound pressure level (Leq) generated by the 2022 US-41 transverse rumble strips at the AASHTO T 390-recommended measurement distances of 25 and 50 feet were lower than those reported in the 2021 study.
