1. A method for sorting among a plurality of potential route plans for operating an autonomous ground based machine at a work site, the method comprising:

  • creating a virtual model of a terrain of the work site;

    creating a first virtual lane within the virtual model, wherein the first virtual lane corresponds to a first proposed route plan of the plurality of potential route plans and has at least one measurable lane constraint;

    creating a first virtual machine footprint having a first virtual movement profile, wherein the first virtual machine footprint corresponds to an actual footprint of the autonomous ground based machine and the first virtual movement profile corresponds to an actual autonomous movement profile of the autonomous ground based machine;

    moving the first virtual machine footprint from a starting position along the first virtual lane to an ending position along the first virtual lane according to the first virtual movement profile;

    during the moving step, comparing the first virtual machine footprint to the at least one measurable lane constraint; and

    designating the first proposed route plan as either viable or unacceptable based on the comparison of the first virtual machine footprint to the at least one measurable lane constraint.
