Abstract
A method for managing haul routes in work environments comprises receiving performance criteria associated with a haul route and establishing a target total effective grade for at least one machine associated with the haul route based on the performance criteria. The method also includes collecting performance data associated with the at least one machine. A drive axle torque of the at least one machine is determined and an actual total effective grade associated with the at least one machine is estimated. The at least one machine is identified as an underperforming machine if the actual total effective grade for the at least one machine exceeds the target total effective grade. An average total effective grade for the at least one machine is determined as a function of the actual total effective grade. A haul route deficiency is identified if the average total effective grade exceeds a threshold level.
