Guide for Applying Quantitative Highway Safety Analysis Methods

The American Association of State Highway and Transportation Officials (AASHTO) Highway Safety Manual (HSM) is a guidance document for incorporating quantitative safety analysis in highway planning and development processes. Many procedures contained in the HSM are complex and challenging for the average practitioner to apply. Given the complexities of the HSM, some practitioners may not use the manual to its full potential. Currently, a new edition of the HSM is in development (HSM-2); this edition will have new and expanded analytical tools. A vigorous and in-depth guide is needed to enhance practitioners’ abilities to use HSM procedures to integrate roadway safety across transportation agency program areas. The objective of this project is to develop a guide focused on the use and application of quantitative highway safety analysis methods in the HSM-2 for informing decisions throughout the project life cycle, including but not limited to programming, planning, preliminary engineering, final design, construction, maintenance, asset management, assessment of transportation impacts from development, and traffic operations. The guide will assist practitioners from diverse professional backgrounds and levels of expertise to navigate and properly apply tools in the HSM-2. As a companion document, the guide should use references and not replicate content from the HSM-2.
