Utilização de Matriz de Risco para análise de microacessibilidade física em uma via arterial

Abstract

In big urban areas, walking is a way of displacement quite used by the population. Therefore, is essential that the route is made with comfort, security and autonomy, according to the rules of Universal Design. Even so, it can be seen, in practice, a precarious infrastructure of sidewalks, which is specially harmful to people with disabilities or reduced mobility, foreclosing their using of urban space and hence theis full inclusion in society. It is necessary, then, a studying of the sidewalks to suggest interventions, with the intention of improve their quality. However, the public authorities don’t have resources to a complete repair instantly, A way would be mapping all the issues and make a list, highlighting the ones that would need a more urgent adjustment. A tool that can be an ally of such study is the Risk Matrix, that consists on illustration of the risks of a situation, determined by the assoociation between the probability that they could happen and their impact, showing easily which risk is the most severe. This study aims to make a field survey of a sidewalk’s sample of Desembargador Moreira Avenue (between Pontes Vieira and Abolição avenues), according to current rules and laws, for determination of risks offered to people in wheelchairs and subsequente elaboratoin of the Risk Matrix. First, is shown a theoretical fundamentation about the subject, and next the proposed method, that was based on the definitioin of the problems (or risks) that would be observed, on ellaboration of the forms to the survey and on utilization of the concepts of impact and probability in order to determinate the intensity of each risk. After this, the results are shown, containing the probability and impact values, some illustrations of problems found during the survey and the risk’s ranking of the chosen excerpt for the study, with relevant discussions about what is displayed.
