MUNICIPAL STRATEGY ON TRAFFIC NOISE REDUCTION - CASE STUDY LISBON

摘要

Due to the demands established by the community directives, related to the Assessment and Management of Environmental Noise, and national law, the competency to elaborate strategic noise mapping, the harmonization of indicators and the evaluation methods of environmental noise is responsibility from the Municipality. We aim to support the elaboration of the Action Plans based upon the noise map with the view to preventing and reducing environmental noise particularly where exposure levels can induce harmful effects on human health and to preserving environmental noise quality where it is good. This project will allow the evaluation of environmental noise using common methods, selecting potential critical areas of noise exposure and the following Noise Reduction Plans. We start with several case studies each leading to a different solution, in order to adopt an environmental strategy of noise reduction. Careful planning shows that, exposure to noise can be avoided or reduced. Control options should take into account the technical, financial, social, health and environmental factors of concern. Cost/benefit relationships, as well as the cost-effectiveness of the control measures, must be considered in the context of the social and financial situation of each community.
