(SR250) Human Factors Guidelines for Road Systems
11/14/2012 1:00 PM - 3:00 PM EST
The Human Factors Guidelines for Road Systems (HFG) (NCHRP Report 600) promote improved safety for highway users. It serves as a complement to existing and planned design guides and standards, such as the Manual on Uniform Traffic Control Devices, AASHTO's Policy on Geometric Design of Highways and Streets, and the Highway Safety Manual. After using traditional resources to develop possible design alternatives to improve safety on an in service or planned intersection or section of roadway, the practitioner may then use the HFG to enhance the possible solutions. The easy-to-use guidelines in the HFG provide the highway designer and traffic engineer with objective, defensible human factors principles and information that can be used to support and justify design decisions. The HFG will allow the non-expert in human factors to recognize the needs and limitations of the road user in a more effective manner in the design and operation of roads that are safer for all. When reviewing either existing or planned roads or intersections, highway designers and traffic engineers are strongly encouraged to use the HFG to identify and develop the safest solutions for road users.
