Abstract(s)Urban growth is continuously applying pressure over resources, infrastructures and facilities, affecting negatively the standard of living in cities. In this 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, which 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 characteristics, acoustical maps were created and overlaid together with the land-use-based acoustic zoning and population distribution layers. This combination was the basis for the identification of critical zones, both in terms of noise levels and people exposure to this kind of pollution. This paper aims to present the approach, including the theoretical framework, and to discuss the results of a summer scenario of noise exposure in the city center.
