Development and Application of Safety Performance Functions in Project Delivery

Iowa
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.
