Based on models of Safety Performance Functions (SPFs), Iowa screened roadway facilities for Potential for Crash Reduction (PCR). PCR was then applied to project screening and prioritization, intersection projects, Super-2 corridor studies, a pilot safety corridor program, and environmental assessments.
