“…The paths from the root to the leaf express classification rules [62]. The DT algorithm is a new tool for analyzing the existing crash dataset and predicting crash severity [63]. In the DT, the value of a particular criterion is generally used to specify each internal node.…”

“…A CHAID tree is a DT that is formed by repeatedly splitting the subsets of the space into two or more child nodes, beginning with the entire data set [66]. To determine the best split at any node, any permissible pair of the categories of predictor variables is merged until there is no statistically significant difference within the pair with respect to the objective variable [63,66,67]. Chi-square tests are applied at each stage in building the CHAID tree to ensure that each branch is associated with a statistically significant predictor of the response variable [68,69].…”
