Book excerpt: This study compared both traditional and empirical Bayes methodologies for ranking high hazard locations and evaluating highway safety treatments for five case studies. The case studies were either based on data collected for previous studies or data retrieved from the Highway Safety Information System (HSIS). These included two high hazard location ranking studies for New York and Illinois and three treatment evaluation studies: Michigan raised pavement markers, Michigan change in posted speeds, and Minnesota traffic signal installation. In addition, an extended empirical Bayes methodology was developed that allows for the use of explanatory variables (covariates) in a regression model along with a computer program for its implementation. The explanatory variables used in these case studies were roadway characteristics such as curvature, pavement width, shoulders, divided highway, and initial posted speed. The regression methodology also allowed for the examination of a nonlinear relationship between vehicle-miles traveled (VMT) and accidents.
