SWOV researchers de Winkel, Christoph and van Nes authored the article 'Towards a framework of driver fitness: Operationalization and comparative risk assessment' in Transportation Research Interdisciplinary Perspectives.
Whereas driver fitness is widely recognized as a prerequisite for safety, the construct lacks a formal framework. We present the first steps towards its operationalization. We interpret availability and allocation of cognitive and physiological resources as fitness dimensions, and risk factors fatigue/drowsiness, distraction/inattention, intoxication, sudden incapacitation and speeding as state variables loading on these dimensions.
