You will find some useful references in the "Noise" chapter of the
"Transportation Cost and Benefit Analysis Guidebook"
(http://www.vtpi.org/tca). Please let me know if you find any additional
information to add.
Traffic noise does tend to increase with:
* Traffic speed (particularly tire and wind noise)
* Traffic acceleration
* Large, heavily loaded trucks and buses (since their engines must work
extra hard)
* Motorcycles
* Vehicles with malfunctioning engines and mufflers
* Horn honking
Traffic noise impacts are also affected by the distance and amount of noise
barriers between traffic and people impacted.
Best wishes,
-Todd Litman
