There are now two highway transportation engineering tools available to highway designers, highway planners, and traffic engineers to help identify driver behavior problems and then select appropriate safety treatments. They are the American Association of State Highway and Transportation Officials' (AASHTO) Highway Safety Manual (HSM) and the Transportation Research Board's (TRB) Human Factors Guidelines for Road Systems (HFG). The HSM may be used to quantify the effects of safety decision-making on crash frequency and severity outcomes when estimating the safety of roadway infrastructure projects. At their inception, the HSM and HFG were envisioned to be living documents that would incorporate new research as it became available. The HSM would focus on improved safety quantitative estimating methodologies and the HFG would focus on road user human factor research as it became available for guideline material. It was recognized that some topics could not be developed in the initial HFG publication. It is expected the upcoming 3rd edition of the HFG will contain chapters for bicycles, motorcycles, roundabouts, and more pedestrian guidelines.
