MONITORING OF DRIVER'S FATIGUE – STATISTICAL ANALYSIS OF TEST DRIVER TRAJECTORIES IN VARIOUS ENVIRONMENTS AND IN DIFFERENT DRIVER STRESS DEGREES

The aim of this work was to develop a methodology for measuring and evaluation of dynamic behavior of the driver in various environments, to determine the differences between the behavior of unwearied and fatigued driver and to propose a development of a mechanism for detection of dangerous situations. Sets of test drives with unwearied drivers were performed on a highway, in the tunnel and at the simulator, followed by statistical analysis. The most suitable characteristics were determined and used for comparison with data obtained from test drives performed within 24 Hours. Allan deviation and Poincare distance are the best parameters for the determination of driver's behavior, because these parameters are calculated from neighboring consecutive samples and carry immediate information about changes of driver's performance. In the experiments with fatigue-influenced driver, the case of vehicle going to get out of the traffic line was well detectable.
