Abstract:
The Connecticut Department of Transportation developed, in 1973, a Statewide Transportation Noise Abatement Program to deal with the growing problem of highway noise in Connecticut. The program provides a mechanism for identifying and evaluating noise impacted areas on a priority basis. A noise abatement project implementation schedule is also developed based on available funding. Two successful noise abatement projects, an earth berm and a wooden wall, have been completed. Noise reductions of up to 10 dBA have been measured at residences located behind these barriers. This paper discusses the program and describes the development and evaluation of the two projects.
