Human factors for safer road infrastructure

Those who are familiar with the jargon of industrial safety engineers know that "Human Factors" is a terminus technicus. In this case the term means a number of psychological and physiological threshold limit values that are relevant in operating machines, cars and technical facilities.

The term Human Factors (HF) includes all qualities that are generally found as characteristical human limitations of perception, thinking, language and memory in operating vehicles and technical facilities. Human Factors are general human qualities that are typical and stable in all people - regardless of origin, culture or age etc. Individual qualities as well as temporary affectivity, illness, medication or special motivations are excluded. For instance drunkenness, over-ambition or heart failure would not count as "Human Factors" because man as such is not generally drunk, over-ambitious or has heart failures.
