Human Factors Guidelines for Road Systems Third Edition

This technical report presents the Human Factors Guidelines for Road Systems, Third Edition (HFG3), developed by the National Cooperative Highway Research Program (NCHRP). The HFG3 aims to assist highway designers, traffic engineers, and other practitioners in integrating human factors principles into roadway design and operations. The document outlines the limitations of existing resources in addressing the needs and capabilities of roadway users, such as drivers, pedestrians, and cyclists. It details the objectives of the project, which include providing a comprehensive resource for safe roadway design, supplementing existing safety tools, and documenting best practices in road safety analyses. The report also summarizes methods for implementing the research findings, including recommendations for making the HFG3 accessible to state Departments of Transportation (DOTs), developing promotional materials, and conducting pilot studies. The anticipated outcomes of the research are aimed at enhancing roadway safety through informed design and operational decisions.
