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.

Data-Driven Strategies Using Predictive Modeling and Interactive Dashboards

Iowa
Since traffic safety projects often yield varying impacts on safety performance, Iowa DOT established a robust system to track crash histories related to safety projects, which is essential to assess project effectiveness, efficiency, and return on investment. The system is helpful to site identification, safety issue diagnosis, and countermeasure evaluation.

B/C Analysis Using Conflict Detection for Midblock Pedestrian Crossings

Georgia
Georgia DOT used conflict detection to assess pedestrian safety at midblock crossings in Jesup, Georgia, allowing for safety concerns to be assessed in further detail than utilizing crashes alone. Using proactive conflict detection data and reactive observed crash data, pedestrian safety projects can be economically justified and prioritized.

Prioritizing Safe System Elements Along a Rural Continuum

FHWA
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.

Aligning Projects and Policies with the Safe System Approach

FHWA
FHWA has a Safe System Alignment Framework for projects, to assess roadway locations and potential infrastructure improvements through a Safe System lens. It also offers a Safe System framework for policy, to assess policies, plans, processes, programs, and documents.
