Urban form indicators as proxy on the noise exposure of buildings
Silva, Lígia Torres; Oliveira, Marta Isabela Fernandes; Silva, José F.Available online 27 September 2013 ; The present paper aims to address the problems of the urban environment as an area of interaction between urban forms and urban noise. This interaction is intended to be monitored using urban indica-tors, by comparing the effects of noise propagation using models of urban forms. The model of noise pre-diction allowed developing noise studies in facades, resulting in noise l...
Observatórios urbanos, ferramentas para monitorização das cidades
Ferreira, Andreia Cristina; Silva, Lígia Torres; Ramos, Rui A. R.O crescimento permanente das áreas urbanas e todos os problemas que esse facto acarreta, faz com que seja importante adotar ferramentas que consigam auxiliar a gestão urbana. Os observatórios urbanos são, então, uma ferramenta que, através de indicadores, permitem a monitorização das cidades, avaliando a sua evolução ao longo do tempo, e comparando-as com outras cidades. Os observatórios são ainda importantes n...
City Noise-Air : an environmental quality index for cities
Silva, Lígia Torres; Mendes, José F. G.Global population growth has led to an increase of the number of people living in urban areas. As a consequence, stresses on space, ecosystems, infrastructures, facilities and personal lifestyles have been enhanced. Problems related to the quality of life in cities are increasingly relevant, especially with regard to environmental issues. Domestic and industrial sources and, primarily, motorised traffic are res...
Urban observatories, tools for monitoring cities
Ferreira, Andreia Cristina; Silva, Lígia Torres; Ramos, Rui A. R.The growth of urban areas, and all the problems that this fact entails, make more immediate the need to search for tools that are able to assist urban management. The urban observatories are, then, a tool that through indicators allows monitoring of the cities, assessing their progress over time. The observatories are also important to support decision making, involvement of people in decisions, data analysis a...
Healthand well-being in urban areas : the WHO Healthy Cities project
Santos, Luís N. V.; Silva, Lígia Torres; Ramos, Rui A. R.; Torres, MargaridaThe increasing number of people in the city takes the countries and organizations to ask themselves about the direction of urban areas in the provision of quality life and sustainability.The WHO promotes the Healthy Cities project to encourage local planning actions to provide more health and sustainability for cities.Viana do Castelo follows this directivedeveloping a monitoring system that allows reflection o...
Electric vehicle and conventional vehicle. Urban air pollution assessment
Vale, Andreia; Silva, Lígia Torres; Rodrigues, Daniel Souto; Ramos, Rui A. R.Road traffic is the main source of air pollutant emissions in urban areas. Pollutant emissions can be evaluated and calculated using mathematical models based on the characteristics of traffic flowing in roads. This article aims to assess the air pollution produced by a fleet of vehicles with conventional (diesel and petrol) and electrical (hybrid and electric) motorization, in the city centre of Braga. The sci...
The influence of urban form on facades noise levels
Oliveira, Marta Isabela Fernandes; Silva, Lígia TorresThe urban form affects directly the natural habitats, ecosystems and the different species. Indirectly the urban form influences the behavior of the trajectory, which in turn affects the air quality, the global climate and of course the noise propagation. This paper seeks to address the problems of the urban environment as an area of interaction between urban forms and urban noise. This interaction is intended...
A proposed methodology for understanding urban growth pattern : a case study in...
Ourng, Chanvoleak; Rodrigues, Daniel Souto; Silva, Lígia Torres; Ramos, Rui A. R.In this paper, the main goal is to understand the relationship between urban growth and physical factors in order to determine the potential area for future urban expansion. A methodology is suggested for understanding urban growth pattern in Siem Reap which could effectively sustain archaeological sites and to balance the land use between urban and non-urban areas in Siem Reap, Cambodia. Remote sensing techniq...
Modeling urban growth pattern for sustainable archaeological sites : a case stu...
Ourng, Chanvoleak; Rodrigues, Daniel Souto; Silva, Lígia Torres; Ramos, Rui A. R.In this paper, the main goal is to understand the relationship between urban growth and physical factors in order to determine the potential area for future urban expansion. A policy is suggested that could effectively sustain the archaeological sites and to balance the land use between urban and non-urban areas in Siem Reap, Cambodia. Remote sensing is used to analyze land use maps of Siem Reap from 1993 to 20...
How urban noise can influence the learning-teaching process. Quantitative and q...
Magalhães, B.; Silva, Lígia TorresThe aim of this study is to evaluate the impact of urban noise and noise generated inside the buildings of elementary schools and its influence on the performance of their students. The sample is consists of the school EB1/JI in Prozela and school EB1/JI in Currais. The first one is located near the International Airport Francisco Sá Carneiro and the other school is surrounded by an electrical substation,...
