Development and Application of Crash Severity Models for Highway Safety: Conduct of Research Report
The first edition of the Highway Safety Manual has provided methods and procedures for
estimating total crashes, crashes by type, and crashes by severity at the site level, project level and
corridor level. Crash prediction models are critical in the entire safety management system recommended
by HSM, including network screening, economic analysis, project prioritization, and safety effectiveness
evaluation.
NCHRP Web-Only Document 351: Development and Application of
Crash Severity Models for Highway
Safety: Conduct of Research Report, from TRB's National Cooperative Highway Research Program, is supplemental to
NCHRP Research Report 1047: Development and Application of Crash Severity Models for Highway Safety: User Guidelines.
The document seeks to identify gaps and opportunities in the current severity prediction/estimation
procedures within the HSM, to develop and validate new severity models to address the gaps and opportunities, and
to develop a guidance document that includes protocols for the use and application of severity-based
models in a format suitable for possible adoption in the HSM.
