Pedestrian Priority Zones in the Context of Urban Mobility and Valorization of Public Space

The second half of the XX century was marked by a great increase in the number of people living in cities. Urban agglomerations became poles of attraction for migration flows and these phenomena, coupled with growing car-ownership rates, resulted in the fact that modern transport systems are characterized by large number of users and traffic modes. The necessity to organize these complex systems and to provide space for different traffic modes changed the way cities look. Urban areas had to cope with traffic flows, and as a result nowadays typical street pattern consists of a road for motorized vehicles, a cycle lane (in some cases), pavement for pedestrians, parking and a range of crucial signage to facilitate navigation and make mobility more secure. However, this type of street organization may not be desirable in certain areas, more specifically, in the city centers. Downtown areas have always been places where economic, leisure, social and other types of facilities are concentrated, not surprisingly, they often attract large number of people and this frequently results in traffic jams, air and noise pollution, thus creating unpleasant environment. Besides, excessive traffic signage in central locations can harm the image and perception of a place, this relates in particular to historical centers with architectural heritage.

IPH response to consultation: Introduction of 20mph speed restrictions on smaller residential streets

Conall McDevitt (SDLP MLA) launched a consultation regarding the introduction of 20mph speed restrictions in residential streets as part of his bid to introduce legislation through a Private Members Bill in the Northern Ireland Assembly.  The purpose of the Bill is to increase road safety, particularly for pedestrians and other road users, with additional health and environmental benefits. IPH submitted a response to the Private Members’ Bill regarding the introduction of 20mph speed restriction on smaller residential roads.  IPH recognises the potential public health benefits of this proposal in terms of reduced injuries and fatalities in built up areas; more opportunities for walking and cycling (helping to tackle obesity and reduce the risk of diabetes, heart disease and stroke); greater social cohesion among communities and improved mental health; and reduced emissions that contribute to climate change, air and noise pollution.

”Public Health Protection through Air Quality Controls”

Health is an important aspect of everybody’s life. Today, there is an increasing recognition and commitment to the pursuit of health both within government and beyond. Any attempt on the part of the " State to protect and promote people’s health, in turn, must be accompanied by effective controls on air quality, as air constitutes ‘ one of the important elements of man’s life and the consequences of air pollution covers a very wide spectrum ranging from material ---damage to personal discomfort and illness. The broad social and economic objectives adumbrated in the Directive Principles of State Policy including the commitment to improve public health underlying in Article 47 and the obligation to preserve and protect-the natural environment cast under Article 48A of the Constitution are being used as versatile weapons by the State to regulate the public health scenario. Preservation and maintenance of air quality is a significant area within the sphere of public health, where the regulatory arm of the law is not adequately touched and in this arena urgent State intervention through legislative and administrative action is called for in the well-being of the society. Judiciary also plays a pivotal role in this arena in the larger interest of the society and for the benefit of the present and future generations. The research study is an attempt to analyze how far the existing legal system, for maintaining air quality and in controlling air pollution, is effective in protecting public health. The study also analyzes the limitations of the control mechanisms. The study focuses on industrial air pollution, indoor and personal air pollution, vehicular pollution and noise pollution which are today appearing as the major public health hazards affecting the air quality. However, this is not to overlook the importance of controls required under other areas of public health.

Identifiering och kartläggning av buller i centrala Falun

Ett problem i dagens moderna samhälle är att bullernivåerna är för höga. Dessa höga bullernivåer är en hälsorisk och kan ge människan permanenta skador. Buller är något som inte får försummas. Syftet med examensarbetet är att identifiera och kartlägga bullret på Holmgatan i centrala Falun. Syftet är också att analysera resultatet och sätta det i förhållande till myndigheternas krav och riktlinjer avseende bullernivåer. Examensarbetet avgränsas till bullermätning och kartläggning på delar av Holmgatan i centrala Falun, som bedömts vara extra utsatta för buller. Bullermätningarna utfördes under fyra vardagar och under tider från det att de flesta affärer öppnar till att de stänger, kl. 10-18. Metoden bestod utav bullermätningar som utfördes med en timmes intervall längs den utvalda delen av Holmgatan. Dagarna då dessa mätningar utfördes var 2/12 till 5/12-2013. Resultatet redovisas som medelvärdet per timme av alla dagar då bullermätningarna utfördes. Resultatet varierade, det lägsta bullermedelvärdet var 57 dB och det högsta bullermedelvärdet var 83 dB. Det syns tydligt att de högre värdena ligger närmare en gata som används av bussar och andra transportfordon. De lägre värdena låg oftast i närheten av Geislerka parken, som är en stor och öppen yta mitt i Holmgatan. Över lag så låg bullermedelvärdena mellan 60-65 dB. Slutsatsen tyder på att bullernivån på Holmgatan överskrider inte myndigheternas krav på vad som anses som skadligt men ligger strax under riktlinjerna för maximalnivån för utomhusbuller (70 dB). Åtgärder såsom att plantera vegitation på fasader och omleda trafiken skulle kunna vidtas för att minska bullernivån på Holmgatan.

Mapeamento acústico como ferramenta para predição de ruído urbano na área de influência do estádio Arena das Dunas, Natal/ RN

The Noise Pollution causes degradation in the quality of the environment and presents itself as one of the most common environmental problems in the big cities. An Urban environment present scenario and their complex acoustic study need to consider the contribution of various noise sources. Accordingly to computational models through mapping and prediction of acoustic scene become important, because they enable the realization of calculations, analyzes and reports, allowing the interpretation of satisfactory results. The study neighborhood is the neighborhood of Lagoa Nova, a central area of the city of Natal, which will undergo major changes in urban space due to urban mobility projects planned for the area around the stadium and the consequent changes of urban form and traffic. Thus, this study aims to evaluate the noise impact caused by road and morphological changes around the stadium Arena das Dunas in the neighborhood of Lagoa Nova, through on-site measurements and mapping using the computational model SoundPLAN year 2012 and the scenario evolution acoustic for the year 2017. For this analysis was the construction of the first acoustic mapping based on current diagnostic acoustic neighborhood, physical mapping, classified vehicle count and measurement of sound pressure level, and to build the prediction of noise were observed for the area study the modifications provided for traffic, urban form and mobility work. In this study, it is concluded that the sound pressure levels of the year in 2012 and 2017 extrapolate current legislation. For the prediction of noise were numerous changes in the acoustic scene, in which the works of urban mobility provided will improve traffic flow, thus reduce the sound pressure level where interventions are expected

A sound education: Becoming aware of the sound around us

In this article it is intended to discuss the issue of noise pollution from an unusual point of view: noise pollution is not only the result of sound increase worldwide, but, particularly, the poor quality of our listening habits in modern life as well. In contemporary society we are subject to a considerable amount of stimulus to all our senses: vision, scent, taste and hearing which are becoming more and more insensible due to over exposure in our environment. These increased stimuli make us look for alternatives to reduce our ability to perceive them and be protected from injuries. However, our sensitivity will also decrease. In the specific case of environment noise, over exposure has made us forget the enchantment of certain sounds that used to give us pleasure or evoke good feelings by many ways, making us recall certain good things, bringing particular moments of our lives to our memory or even filling us with strong emotion. The Canadian composer and music educator, R. Murray Schafer, believes that noise pollution is the result of a society who became deaf. Closing our ears to noise protect us from noise pollution but also prevent us from grasping subtleties of listening. Contemporary world does not help us to be aware of sound in the space around us; acquiring this hearing ability is a matter of focus, interest and practice. Sound education exercises are aimed at children, teenagers and adults who want to improve their listening ability to environmental sounds, perceive its proprieties and learn how sound affects us and touches our feelings. The results are easy to accomplish and contribute to our awareness of the sound environment around us and to the conception of the environmental sound as a composition made by everybody and everything through positive actions, strong will and high sensitivity.

Desenvolvimento e caracterização acústica de painéis multicamadas unifibra, multifibras e mesclados, fabricados a partir de fibras vegetais

Em um tempo em que altos níveis de ruído fazem parte do cotidiano das pessoas, a necessidade de controlá-los não é somente evidente, mas providencial. Atualmente a poluição sonora, em nível mundial, só não é mais grave do que a poluição do ar e da água. No Brasil a situação não é diferente, pois se estima que mais de 15 milhões de pessoas apresentem algum grau de deficiência auditiva devido a este problema ambiental. Dispositivos acústicos como painéis, barreiras, etc., quando de alta eficiência, geralmente, são de custosa aquisição, tornando, em muitas das vezes, inviável sua utilização, principalmente, por empresas de pequeno porte e orçamento limitado. Assim, soluções alternativas, a começar por novos materiais, que sejam menos custosos e possuam desempenho satisfatório surgem como uma ótima opção caso propostas tradicionais sejam inviabilizadas devido ao custo. Algumas fibras vegetais, na forma de painéis, possuem características acústicas satisfatórias quando utilizadas para reduzir a reverberação em determinados ambientes fechados. Dessa forma, considerando as tendências ambientais globais, o uso de fibras vegetais é uma boa oportunidade para agregar valor às referidas fibras e assim contribuir com o desenvolvimento tecnológico do país, já que estes materiais são de fácil obtenção, existem em abundância, não são tóxicos e provêm de fontes renováveis. Este trabalho apresenta a metodologia de desenvolvimento de painéis fabricados a partir de fibras vegetais (açaí, coco, sisal e dendê), assim como a metodologia utilizada para sua caracterização acústica em câmara reverberante em escala reduzida, baseando-se na norma ISO 354/1999. Os dados de coeficiente de absorção dos painéis são obtidos através de um analisador de frequências utilizando-se o Método da Interrupção do Ruído. A comparação entre os resultados obtidos para os painéis artesanais e os materiais convencionais ensaiados permite concluir que o desempenho acústico demonstrado por alguns painéis de fibras vegetais são muito satisfatórios, uma vez que seus coeficientes de absorção sonora foram compatíveis, e em alguns casos superiores, àqueles apresentados pelos materiais convencionais em determinada faixa de freqüência. Finalmente, uma comparação numérico-experimental é realizada, a fim de avaliar a influência de painéis de fibras de sisal sobre as características acústicas de uma pequena sala.
