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.

AWSC at Low-Volume Unsignalized Intersections

Delaware
With 40% of fatalities and serious injuries occurring at low-volume, unsignalized intersections, DelDOT implemented All-Way Stop Control. After three years, there were zero fatalities and 82% fewer injury crashes at the intersections evaluated.

Data for Proactive Road Safety: Continuous Pavement Friction Measurement

Kentucky
Pavement Friction Management (PFM) using Continuous Pavement Friction Measurement (CPFM) is a proactive approach for managing pavements for safety throughout the roadway lifecycle. Taking a lifecycle approach to designing, specifying, and maintaining friction performance saved Kentucky more than $1 billion annually and reduced fatal and severe crashes by up to 24%.

Method for Short-Term Network Screening

Iowa
Iowa DOT's short-term network screening method identifies freeway segments most likely to have excess crashes in coming weeks, which helps prioritize emergency response and enforcement. Seasonal conditions (weather, animal crossings) may be factored into crash risk. The method can also help with the design of effective countermeasures.
