Abstract GUIDANCE SYSTEM FOR A MOBILE MACHINE Disclosed is a method of determining a grade of a roadway (14) bordered by a marker (16) including a bottom that contacts the roadway, with a 5 machine (12) traveling on the roadway, the method comprising locating, with a scanning device (30), a first point indicative of the bottom of the marker at a first geographical location along the roadway; locating, with the scanning device, a second point indicative of the bottom of the marker at a second geographical location along the roadway; and comparing the locations of the first point and the 10 second point to determine the grade of the roadway. Also disclosed is a method of determining a bank of a roadway (14) bordered on a first side by a first marker (16) including a bottom that contacts the roadway and bordered on a second side by a second marker (16) including a bottom that contacts the roadway, with a machine (12) traveling on the roadway, the method comprising locating, with a 15 first scanning device (30) mounted on one of a left and right side of the machine, a first point indicative of the bottom of the first marker at a geographical location along the roadway; locating, with a second scanning device (30) mounted on the other side of the machine, a second point indicative of the bottom of the second marker at the same geographical location; and comparing the locations of the first 20 point and the second point to determine the bank of the roadway. |
