  • Systems and methods for haul road management based on greenhouse gas emissions
    Patent number: 8090560
    Abstract: A method for haul road design based on greenhouse gas emissions comprises receiving a first set of performance data associated with a plurality of machines and establishing a greenhouse gas emission limit for the plurality of machines based on the first set of performance data. A target greenhouse gas emission level for each of the plurality of machines is determined based on the greenhouse gas emission limit, and total effective grade is determined based on the target greenhouse gas emission level for the respective machine. The method also includes generating a haul road design based on the total effective grade.

  • Systems and methods for improving haul road conditions
    Patent number: 8014924
    Abstract: A method for improving haul road surface conditions comprises collecting performance data associated with at least one machine operating on a haul route and determining a rolling resistance of each of the at least one machine based on the performance data. An average rolling resistance associated with one or more portions of the haul route is determined based on the rolling resistance of each of the at least one machine. The one or more portions of the haul route are identified as irregular if the average rolling resistance of the one or more portions exceeds a threshold resistance value. A proposed modification to the irregular portion of the haul route is generated, and performance of the at least one machine is simulated based on the proposed modification. The method also includes outputting results of the simulated performance.
