1. A guidance system for a machine, comprising:
- a scanning device configured to generate a signal indicative of an actual lateral distance from the machine to a roadway marker;
a locating device configured to determine a geographical location of the machine; and
a controller in communication with the scanning device and the locating device, the controller being configured to;
receive a desired lateral distance from the machine to the roadway marker, the desired lateral distance being adjusted based on at least one of geographical location, a condition of a roadway being traversed by the machine, a condition of the machine, or an experience of a machine operator;
compare the desired lateral distance to the actual lateral distance; and
implement a response to the comparison based on at least one of the geographical location, the condition of a roadway being traversed by the machine, the condition of the machine, or the experience of a machine operator.

Abstract
A guidance system for a mobile machine is disclosed. The guidance system may have a scanning device configured to generate a signal indicative of a lateral distance from the machine to a roadway marker, a locating device configured to determine a geographical location of the machine, and a controller in communication with the scanning device and the locating device. The controller may be configured to receive a desired lateral distance from the machine to the roadway marker, and to compare the desired lateral distance to the actual lateral distance. The controller may further be configured to implement a response to the comparison based on the geographical location.

12. A method of guiding a machine, comprising:
-
measuring an actual lateral distance from the machine to a roadway marker; receiving a desired lateral distance from the machine to the roadway marker; comparing the actual lateral distance and the desired lateral distance; determining a geographical location of the machine and determining a severity of the machine contacting or crossing the roadway marker based on the geographical location; and implementing a response to the comparison based on the severity. - View Dependent Claims (13, 14, 15)

16. A machine, comprising:
-
a power source; a plurality of traction devices associated with the power source to propel and steer the machine; a scanning device configured to generate a signal indicative of an actual lateral distance from the machine to an earthen berm; and a controller in communication with the scanning device and the locating device, the controller being configured to; receive a desired lateral distance from the machine to the earthen berm, the desired lateral distance being adjusted based on a risk value; compare the desired lateral distance to the actual lateral distance; and implement at least one of a warning provided to an operator of the machine or corrective maneuvering of the machine in response to the comparison based on a magnitude of the risk value.
