The Application of the Level-crossing Theory of Multidimensional Random Processes to the Evaluation of Vehicle Operators’ Performance

The application of the level-crossing theory of multidimensional random processes to the evaluation of the vehicle operators’ performance allows not only evaluating the possible deviation from parameters, but also considering the dynamics of the parameter changes. The level-crossing intensity is acquired for normal distribution random process correlated by two dimensions, as well as for the multidimensional process when a maximum mutual correlation of parameters is considered. The criterion is defined that allows evaluating the possibility that none of the parameters will reach an unacceptable value.
