Long Description: Figure C6. Control Double Vehicle Off-tracking Calculation for the 12-ft. Lane Change

Figure C6 plots the path of each axle center for a 12-ft. lane change for the control double vehicle. Off-tracking was computed as the difference in Y values (lane position) of each trailing axle from the steer axle. The worst off-tracking of the truck at this excitation frequency was 12.75 - 11.42 or 1.33 ft., which was reported as 16 in. This process was repeated for the eight excitation frequencies in order to find the global highest absolute off-tracking value.
