<\/span>Did WisDOT consider noise levels as part of the I-94 project?<\/h4>\n

Yes, it was a federal requirement. U.S. noise regulation (23 CFR 772) requires state highway agencies to determine noise impacts and evaluate possible mitigation measures as part of a proposed Type I Federal Aid project. I-94 is considered a Type …<\/p><\/div>\n <\/article>

\n

<\/span>How did WisDOT determine where to place noise barriers?<\/h4>\n

The Traffic Noise Model (TNM 2.5)\u00ae was used to predict future traffic sound levels. Impacted locations were then considered for noise abatement measures. Project staff evaluated potential design and traffic control modifications, such as prohibiting trucks or changing the horizontal …<\/p><\/div>\n <\/article>

<\/span>What is an impacted receptor?<\/h4>\n

An impacted receptor\/listener or common use area is one with:<\/p>\n

  • A predicted future traffic sound level which approaches or exceeds the WisDOT Noise Level Criteria (NLC) for Considering Barriers for different land use categories;<\/li>\n
  • Or when predicted future traffic sound <\/li><\/ul>…<\/div>\n <\/article>
    \n

    <\/span>Are there impacted receptors along I-94?<\/h4>\n

    Yes. Approximately 154 receptors were modeled as part of the noise analysis for the project. Approximately 25 receptors are considered impacted since future noise levels are anticipated to approach or exceed the NLC.…<\/p><\/div>\n <\/article>

    \n

    <\/span>What does feasible and reasonable mean?<\/h4>\n

    For a noise abatement measure to be feasible, a minimum of one impacted receptor or common use area must achieve a five (5) decibel noise reduction. For a noise barrier to be reasonable, the total cost may not exceed $30,000 …<\/p><\/div>\n <\/article>

    \n

    <\/span>How effective are noise barriers?<\/h4>\n

    Effectiveness depends on the distance between the impacted receptor and the barrier. For areas located directly behind a barrier providing an eight (8) dB reduction, the noise level will be perceived as being cut in half. This benefit decreases as …<\/p><\/div>\n <\/article>

    <\/span>Are noise barriers reasonable for the I-94 corridor from WIS 35 North to US 12?<\/h4>\n

    Noise barriers were evaluated in the areas of the impacted receptors. The noise barriers in most areas were well in excess of the reasonable cost of $30,000 per benefited receptor. In the southwest quadrant of the WIS 35 South Interchange, …<\/p><\/div>\n <\/article>

    <\/span>Will WisDOT consider noise levels during construction?<\/h4>\n

    Yes. The noise generated by construction equipment will vary greatly, depending on equipment type\/model\/make, duration of operation and specific type of work effort. Typical construction noise levels are shown in the table below.<\/p>\n
