Análise estatística dos acidentes ferroviários nas principais malhas do Brasil

Abstract

In 2022, 400 railway accidents were recorded on Brazil’s main railway networks. This work proposes a comprehensive statistical analysis of railway accidents that occurred from 2015 to 2022, focusing on the Southern, Northern, Western, and Paulista networks, intending to enhance the quality of processed information and identify occurrence patterns. The methodology is based on developing a structured process, employing statistical methods to analyze the collected data, and focusing on the accident’s circumstances, causes, and consequences. The analysis results served as the basis for creating a risk panel in the form of a dashboard, allowing for accessible and intuitive data visualization. The visualizations developed were tested by the endusers and ultimately, this tool facilitated the identification of preventive measures, such as analyzing the optimal train circulation times, to reduce the quantity and severity of railway accidents in the studied regions. This study has contributed to railway safety by providing essential information on critical times, high-risk locations, and contributing factors to accidents.
