This two-hour training will provide an overview of human factors principles . It will allow the non-expert in human factors to more effectively bring consideration of the road user’s capabilities and limitations into policies and practices. Knowing how road users interact with their vehicle, the roadway and other road users can also provide useful insights into roadway safety. Armed with that knowledge, construction and maintenance personnel, planners, engineers, public health professionals and law enforcement can work together to target appropriate countermeasures to help reduce injury crashes.
