The coded variables in the different files are not consistent and little information on accident etiology is collected. Examples of the inadequacies of present data in terms of the collected and coded variables are show. A system approach is needed to identify critical, currently neglected variables and develop units of measurement and data collection procedures. The system view would be based on the paradigm of the human operator in a man-machine system, simultaneously performing tracking and vigilance tasks and making decisions in a varying environment. By increasing utilization of more dophisticated mathematical models of man-machine systems and controlled laboratory experiments, sets of critical variables could be defined and their interactions studied, both theoretically and experimentally. /GMRL/
