A method of adjusting an operator workload during a travel segment including tracking over a time period, using at least one sensor, one of inputs by an operator indicative of an operator workload or image sensor data or a biometric parameter indicative of an operator stress level during the travel segment. Determining, using a controller that is operatively connected to the at least one sensor, a level of one of the operator workload or operator stress level. The method also includes adjusting, using a controller that is operatively connected to the control computer, the operator workload when the level of one of the operator workload or operator stress level exceeds a predetermined threshold.
