Problem Statement
Although current and historical efforts to reduce transportation-related noise have been costly to develop, implement, and enforce, the nature and magnitude of their specific costs have not been well documented or accurately measured. As a consequence, policymakers may not have been thoroughly informed with regard to decisions on the design of noise-regulation and control strategies and the allocation of resources among different measures to reduce noise impacts. Maintaining support for the continued investment in noise-reduction technologies, including noise-modeling tools, and the development of effective noise-regulation strategies is contingent upon developing a more complete understanding of the costs of transportation noise, including the cost associated with further reductions on noise and the economic impacts of residual uncontrolled noise. In addition, it is imperative to understand the measurable benefits of an effective, well-rounded noise-control strategy, which includes elements of source noise control, operational techniques, and land use planning, including the design and development of accurate prediction tools

Proposed Research
The objective of the proposed study is to determine how past funds have been spent with regard to transportation noise reduction and to make recommendations on how to best allocate future funds, taking into account the potential benefits associated with particular decisions.

The study will include a general account of past expenditures and a related evaluation of effectiveness. In short, the study will address the following three questions:
1. On what projects have noise-related funds been spent?
2. How effective were these projects at accomplishing their goal of noise reduction; that is, what benefits were reaped?
3. How are future noise-related funds best spent?
In addition, this study will produce guidelines that will explain the process for conducting a noise cost-benefit analysis. This document will serve as a prototypical cost benefit tool.
