Avaliação da oferta de transporte público no bairro Tirol (Regional Barreiro Belo Horizonte MG): uma abordagem logística

Abstract

This study presents an analysis of the public transportation network in the neighborhood of Tirol located in Barreiro, one of the nine administrative regions of Belo Horizonte municipality. To this end, only the network managed by BHTRANS Company (Empresa de Transportes e Trânsito de Belo Horizonte S/A) has been considered. In Tirol, the public transportation network is constituted of both conventional and supplementary lines. However, the conventional lines alone will be considered here, since the only up-to-date geo-reference database available is related to them. Using ArcGis, a Geographic Information System (GIS) software, the data can be manipulated in order to enable the application of a methodology to calculate a public transportation offer indicator for each of the Census population sectors within the neighborhood boundaries. This analysis scale has been chosen because it promotes the correlation between population density and head of the household average income, an information that has not been provided by IBGE (Brazilian Institute of Geography and Statistics) in a neighborhood scale. Thus, data on income and population density pertaining to each sector census, for the Census of 2010, the last Census conducted, were surveyed along to it. However before the numerosity of information acquired in this research, the IBGE data computed at different times, according to a chronology of information processing. Thus, during preparation of this monograph, the IBGE, was presented only to the level of census tract data on population. In the absence of data on income, using the database of the Census of 2010, proved to be incompatible to the development of the proposed methodology. Therefore, we chose to use the information pertinent to the 2000 census that includes the variables of population and income per census tract. With the spatialization of these elements, it is possible to establish a correlation between offer indicators, population density and economic profile. In most of the Census population sectors, the analysis has identified a strong correlation between level of public transportation offer and head of the household average income. However, this relation was not observed when evaluating population density versus offer indicator, which can be seen as an evidence that there are other factors contributing to one's choice of neighborhood other than public transportation availability. Furthermore, the information gathered enabled the identification of the accessibility level the population is exposed to.
