Safety Network Screening was conducted for arterial/collector intersections in the city and surrounding area of Madison, Wisconsin. A total of 4,062 intersections were evaluated. The Equivalent Property Damage Only (EPDO) index was used as safety performance measure to identify and rank roadway facilities for potential safety improvements. Wisconsin CODES data were used to estimate jurisdiction specific intersection crash costs by crash type and severity Following the Highway Safety Manual guidance, the EPDO with Empirical Bayes adjustments was implemented to account for regression to the mean and crash severity. Intersections were ranked according to the magnitude of the EPDO index to identify sites with potential for safety treatment.
