Applying the Human Factors Guidelines For Road Systems (HFG) To The Road Safety Audit (RSA) Process

This paper describes the activities and results associated with a pilot study to assess the value and efficacy of the Human Factors Guidelines for Road Systems, Report 600, Second Edition (HFG) for conducting road safety audits (RSAs). Published by TRB, the HFG provides focused discussions of design issues and design solutions in the context of a detailed presentation of road user needs, capabilities, and limitations. The HFG summarizes human factors principles and concepts that could be used primarily by roadway designers, traffic engineers, and safety professionals to improve roadway design and traffic safety. Five states in the United States (U.S.) participated in the pilots and, across these states, a total of 190 end-users were given in-person, instructor-led training on the objectives, contents, and application of the HFG. Of the five U.S. states participating in the pilot study, three states—Arizona, Nevada, and Wisconsin—used the HFG to support the conduct of multiple RSAs. Results from twelve RSAs on existing roadway facilities using the HFG across the three states are provided. The results highlight the facility type, critical safety issues being studied, and specific chapters and guidelines in the HFG that provided valuable insights, design solutions, and countermeasures. Though the pilot study was preliminary and qualitative, the contents and materials presented in the HFG provided consistent value and aid to a diverse group of engineers and safety professionals. A regular theme in the feedback provided by the pilot states was that the HFG provided end-users with practical, implementable solutions to real-world problems. This report highlights the key human factor guidelines these three states used in their RSA studies.
