Análise estatística das ocorrências de acidentes ferroviários na região Centro-sudeste paulista, causas e consequências

Abstract

The present study aimed to cross information collected during eight years of occurrences and their causes in the central-southeast region, to find possible causes of these occurrences and to estimate the percentage of repetition of these causes in the occurrences. This research is justified by its contribution in terms of greater efficiency in transport by the networks, reducing losses, increasing exports and reducing the economic impact in order to integrate the railroad to the means of transportation. Data was collected on all railway occurrences in the Central-southeast region of São Paulo between 2010 and 2018 (1156 cases). The statistical significance of the associations verified by the non-parametric test of χ2 (chi-square) was obtained. The results showed the locations of Uberlândia, Valefértil and Jardim do Ingá as the places where accidents occur more frequently and that have the largest number of derailments; the Permanent Way is responsible for most of the accidents, which mostly result in derailment in the Uberlândia, Valefértil and Jardim do Ingá sites; business security is linked directly to accidents caused by third parties (collision and trampling); and collisions occur more frequently on trains with empty wagons, unlike derailment, which occurs mostly with trains with loaded wagons.
