Estimation of safety performance functions for urban intersections using various functional forms of the negative binomial regression model and a generalized Poisson regression model

•Multiple safety performance functions (SPFs) are developed by crash severity for urban intersections.•Three functional forms of negative binomial (NB) models and a generalized Poisson (GP) model are used to develop the SPFs.•The developed SPFs are compared based on goodness of fit and predictive pe...
