Prior to this research project, state highway agencies did not have tools for reflecting safety in their decisions concerning freeway and interchange projects.
The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 306: Safety Prediction Methodology and Analysis Tool for Freeways and Interchanges documents a safety prediction method for freeways that is suitable for incorporation in the Highway Safety Manual. Within the document are Appendices A through F: Practitioner Interviews, Database Enhancement, Proposed HSM Freeways Chapter, Proposed HSM Ramps Chapter, Proposed HSM Appendix B for Part C, and Algorithm Description.
Supplemental to the document are an Enhanced Safety Analysis Tool, a User Manual for the Tool, a Workshop Agenda, an Instructor Guide, and a PowerPoint Presentation.
The report and supplemental material are available on the National Academies web site at https://www.trb.org/Main/Blurbs/182569.aspx
