In addition, European efforts to conduct cost-benefit analyses on highway noise are reviewed, as is pavement research that will lead to lower noise levels and will be a vital input to any cost-benefit analysis model.

Quiet pavements reduce noise by controlling the surface characteristics of the pavement. Much less documentation is available on the costs for pavement modifications by resur facing and grinding than on the costs of noise barriers.
