Analysis of traffic accidents on rural highways using Latent Class Clustering and Bayesian Networks

► The simultaneous use of Latent Class Clustering (LCC) and Bayesian Network (BN) is useful for road safety analysis. ► LCC is used to reduce heterogeneity in the traffic accidents data. ► BNs are used to identify the main factors that contribute to traffic accident severity. ► For each cluster and for the entire database we built and compare the BN's results. ► This comparison allows identifying new information and insights that would not have been possible to obtain without a previous LCC analysis.
