Um método para análise e visualização de dados georreferenciados relacionados ao trânsito de veículos

Abstract

Traffic accidents of vehicles are one of the biggest causes of deaths in the world's young population, and there is a tendency to increase this number in the next years. The occurrence of accidents is influenced by several factors, such as road conditions, climatic conditions, law enforcement by government agencies, among others. It would be interesting to know in more detail which of these factors has the greatest influence. On the internet, there is an immense amount of data generated by diverse agencies and companies, but much of this information is not analyzed, either because of lack of access, or because the data is not structured in a way that allows its understanding. The availability of data is increasing, either through open data policies implemented by the government, or through collaborative web tools, which make it possible record information by population, and subsequently make their data available. This work proposes a method of grouping georeferenced data from several sources, to perform a statistical analysis using the technique of Principal Components Analysis, which can identify in a georeferenced way which characteristics influence more in the occurrence of traffic acidentes of vehicles. After the analysis, a new methodology for visualizing results, plotted on maps, is explored, which can serve as an aid to government agencies and decision makers who take actions to reduce traffic accidents.
