Macro-Level Analysis of Safety Planning and Crash Prediction Models: A Guide
The
Highway Safety Manual (HSM) is a tool that helps transportation agencies make data-driven
decisions about safety. It includes methods for quantifying safety performance and predicting
crash frequencies. The HSM is currently being updated to include macro-level crash prediction models,
which can be used to assess safety trends at a regional or national level.
NCHRP Web-Only Document 348: Macro-Level Analysis of Safety Planning and Crash Prediction Models: A Guide,
from TRB's National Cooperative Highway Research Program,
provides guidance on how to use a
spreadsheet tool developed during this project.
The document is supplemental to
NCHRP Research Report 1044: Development and Application of Quantitative Macro-Level Safety Prediction Models.
