Toward the “Human Stability” in Transportation Systems: Concept and Objectives.

Human errors are responsible for about 70% of incidents and accidents in transportation systems. This paper proposes to take into account human stability whose main objective is to improve risk control. A reminder of definitions on different terms (robustness, resilience …) is provided to position the human stability in relation to these terms. Then, a definition of “human stability” is proposed in the form of states of stability and transitions. A first formalism, mono-criterion, is proposed and applied to a transportation system: air traffic control.
