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.

Using Before and After Tools to Make Data Driven Safety Decisions

New Jersey
As part of the HSIP, NJDOT uses observational before/after analyses with a volume adjustment tool to evaluate countermeasure effectiveness and safety benefits. For example, post-deployment evaluation of centerline rumble strips showed a total crash cost benefit of more than $11 million for all target crashes.

Get Involved with Transportation Research Board (TRB)

NCHRP
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, contribute to TRB Standing Committees, and volunteer for project panels.

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.
