1.1 Overview of Human Factors Guidelines for Road Systems: Design and Operational Considerations for the Road User Human Factors Guidelines for Road Systems: Design and Operational Considerations for the Road User is a guidance document that brings human factors principles and findings to the highway designer and traffic engineer. It will allow the non-expert in human factors to more effectively bring consideration of the roadway user into practice about design, operations, and safety.

Human factors is the scientific discipline that studies how people interact with devices, products, and systems. It is an applied field where behavioral science, engineering, and other disciplines come together to develop the principles that help assure that devices and systems are usable by the people who are meant to use them.

Traffic engineering practice certainly did not develop ignoring the driver. But systematic data on driver capabilities and performance as a resource for design practice is relatively recent.

given changes over the years in roadways, vehicles, traffic, operations, and even drivers. • Both the roadway system and human behavior are complex and there may be some applications where a minimum design requirement is insufficient to support the desired driver behavior.

considerations, the guidance can help identify probable human factors causes or countermeasures. The document is constructed so that links among chapters and sections help the reader connect related issues, provide key background information when needed, and relate site features and traffic engineering elements.
