When is ADOT going to conduct additional noise measurements?

Because of the COVID-19 pandemic, average daily traffic volumes throughout Maricopa county are lower than usual. Taking noise measurements during this pandemic is not representative of typical traffic noise levels. ADOT is planning to resume field noise testing in late summer/early fall 2020 and in late February/early March 2021. Beyond that, ADOT will continue testing noise levels throughout the 22-mile corridor regularly in select locations. Schedules are subject to change because of the pandemic and other unforeseen situations.

I would like a bit of clarification regarding what installs and active devices are reported.

  • Report all installs that were done in Arizona (Arizona compliant) and/or for Arizona requirements, regardless of the reporting agency.
    • We don't want those installed in AZ reporting to say... Texas. These devices probably will not be compliant with AZ since the other state has different requirements and settings.
    • If they have an AZ requirement, installed in another state, report it.
      • If for some reason they are compliant with AZ, installed in another stated and don’t have an AZ requirement and don’t live in AZ, don’t report them.
