TRANSPORT DEVICE OPERATOR STRESS FEATURES ANALYSIS D. Anita Wo niak Marshal's Office of the Malopolska Voivodship Basztowa 22, PL 31-156 Krakow, Poland

The paper is focusing on known publications review concerning the transport device operator stress features and identification possible and their influence at man decision making process. The paper composition include: stress phenomenon analysis, human features and stress interaction analysis, human availability models including stress factors, and stress analysis tools analysis. Stress has been recognized as a major influential factor to affect the operator's health, safety, and productivity. Stress is subjective and express man reaction from external to potential reactions. The operator stress is often expressed as quality of life indicators related to satisfaction with a given domain of functioning and have influence at the human operation potential (health). Studies on the role of the state of mental and physiological functions are an important part of the theory of operators working reliability and a causeand-effect relationship between the functional state and their availability. The review on known selected publications concerning the transport device operator stress features and others, including own research, helps to identify possible stressors acting at man and their influence at decision making process. The measure possible stress parameters: physiological, subjective and behavioral types have also been discussed. The transport devices’ operator fatigue remains to be one of the important factors that contribute to possible accidents accompanying transportation processes. The problem of availability and reliability of human operators activities are today more practically oriented crucial and a branch of applied psycho-physiological research.
