Abstract

Evaluating critical noise disturbance zones in a mid-sized city J. F. G. Mendes & L. Silva Department of Civil Engineering, University of Minho, Portugal Abstract Urban growth is continuously applying pressure on resources, infrastructures and facilities, negatively affecting the standard of living in cities. In h s context, evaluating and monitoring the urban environmental quality has become a main issue, particularly important when considered as a decision-support tool that contributes to more livable and sustainable cities. Viana do Castelo is a mid-sized city located on the northwest Portuguese seaside, whch undertook the challenge of developing an environmental program leading to the integration in a Healthy Cities European Network. Within this program, the identification of urban noise levels and people exposure was considered a priority. The scientific toolbox adopted to develop the studies includes noise simulation models and a GIS platform. Based on traffic data and site physical cha
