Railroad accident analysis using extreme gradient boosting

Abstract: Railroads are critical to the economic health of a nation. Unfortunately, railroads lose hundreds of millions of dollars from accidents each year. Trends reveal that derailments consistently account for more than 70% of the U.S. railroad industry's average annual accident cost. Hence, knowledge of explanatory factors that distinguish derailments from other accident types can inform more cost-effective and impactful railroad risk management strategies. Five feature scoring methods, including ANOVA and Gini, agr… Show more

“…Therefore, estimating and mitigating the consequences of potential accidents would increase railway operational efficiency. The goal of the (Bridgelall & Tolliver, 2021) study was to identify factors associated with the most frequent and expensive types of accidents that are not attributable to human error. Their paper on railway accidents states that nearly 71% of the average annual financial loss of US railways is related to derailment accidents.…”

“…A blind approach to finding the best hyperparameters for a classifier is to conduct several cross-validation cycles and plot the performance trends with different hyperparameter settings (Bridgelall and Tolliver 2021). Of course, doing so also requires selecting the best crossvalidation type, the cross-validation parameters, the performance scores to monitor, and the number cycles to average those scores.…”

“…combined the zero-inflated Poisson regression model, the zero-inflated negative-binomial regression model, the zero-inflated gamma regression model and the zero-inflated log-normal regression model to propose a new approach for evaluating the damages resulting from railway accidents in Korea. Bridgelall and Tolliver [16] analyzed railroad derailment accidents using extreme gradient boosting. An interpretive structural modeling and Bayesian network combining approach was applied by Huang et al [17].…”
