The AASHTO Highway Safety Manual (HSM) provides fact-based, analytical tools and techniques to quantify the potential safety impacts of planning, design, operations, and maintenance decisions.
The TRB National Cooperative Highway Research Program's NCHRP Research Report 983: Reliability of Crash Prediction Models: A Guide for Quantifying and Improving the Reliability of Model Results complements the HSM by providing methods for consistently ensuring model reliability.
Supplemental to the report are NCHRP Web-Only Document 303: Understanding and Communicating Reliability of Crash Prediction Models, a communications plan, a flyer, and a PowerPoint presentation.
