Buildings are constructed for the use of humans, and all building codes are developed using human factors as they apply to buildings. As an egineer I could not design a building without being cognizant of human factors as they apply to buildings. The hallway width, door heights, lighting, handrail heights, floor loads, desk height, stair dimentions are examples of human factors implemented in buildings.
Likewise, automobiles are operated by humans and roadways are designed by impletmenting human factors. Sight distances, perception reaction times, illumination, pedestrian interaction, whiplash levels are examples of human factors as they apply to transportation.
