Assessment and mitigation of community noise impacts from major highway projects-a proponent's approach

Abstract

The assessment and mitigation of community noise impacts from major highway projects are discussed. The Ministry of Transportation (MoT) policy for noise impacts at residences contains a mitigation eligibility scale which permits larger project related noise increases where pre-project noise levels are lower. The graphical representation of the revised MoT noise policy is also presented. It is found that an average noise environment of 55 dBA or less is fully compatible with residential land use.
