Breaking Barriers: Alternative Approaches to Avoiding and Reducing Highway Traffic Noise Impacts

The objective of this research is to develop a resource of innovative approaches--beyond the use of noise barriers--to avoid and minimize highway traffic noise and address complaints. The resource should provide descriptions, ranges of noise reduction benefits, cost factors, and context-appropriateness for design choices and management strategies that may be adopted for other reasons, but that provide noise reduction co-benefits, as well as those adopted specifically to address noise.
