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.

Get Involved with Transportation Research Board (TRB)

NCHRP and BTSCRP develop resources for DOTs, transportation professionals, and other agencies. Resources include research related to the AASHTO Highway Safety Manual and AASHTO Manual for Assessing Safety Hardware, safety guides for practitioners, and behavioral research. Transportation professionals may contribute problem statements, conduct research, and volunteer for project panels.

The Safe System Approach in Minnesota

Minnesota

The MnDOT Safe System Approach (SSA) implementation plan has the goal of institutionalizing the SSA across the agency. will be a framework leading the agency to broad application of SSA principles throughout the project development process. The SSA will be seen as an approach for staff at MnDOT to utilize in their work toward eliminating fatalities and serious injuries.

Data for Proactive Road Safety: Continuous Pavement Friction

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%.

Prioritizing Safe System Elements Along a Rural Continuum

This pilot effort created a new way of looking at rural safety needs on a continuum. The project used six characteristics: block size, distance to fire stations, distance to public schools, distance to Level 1 & 2 trauma centers, intersection density, and undeveloped land.
