[sustran] Re: On Noise Pollution

[Todd Alexander Litman]

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
