The statistical analysis of highway crash-injury severities: A review and assessment of methodological alternatives

► This paper provides a state-of-the-practice review of statistical methods for analyzing crash-injury severity data. ► Methodological issues germane to the analysis of injury severity data are discussed. ► Appropriate techniques for addressing these methodological issues are described. ► These techniques range from simple, binary outcome models to more sophisticated models allowing for heterogeneous effects and correlated error terms. ► Areas of opportunity for future research are highlighted based upon advances in computing and richer data sources.
