Highway Safety Manual

A new generation of highway safety analysis tools is being deployed to the transportation community through several innovative research efforts. The Highway Safety Manual (HSM) is published by the American Association of State Highway Transportation Officials (AASHTO). FHWA has developed supporting implementation tools including the Interactive Highway Safety Design Model (IHSDM) and the Crash Modification Factors (CMF) Clearinghouse. These tools will greatly advance state and local highway agencies' ability to incorporate explicit, quantitative consideration of safety into their planning and project development decision making.

The first edition of the HSM provides the best factual information and tools in a useful form to facilitate roadway planning, design, operations, and maintenance decisions based on precise consideration of their safety consequences. The primary focus of the HSM is the introduction and development of analytical tools for predicting the impact of transportation project and program decisions on road safety.

AASHTO’s Highway Safety Manual Webpage

AASHTO’s Highway Safety Manual webpage, highwaysafetymanual.org, serves as the official HSM website where you can find the most up to date information and new developments on the HSM.
