Abstract
The present invention provides a method and apparatus for automatically limiting the ground speed of a work machine. The work machine is adapted to move about the ground of a work site. An electronic site map having at least one speed restriction is maintained at a site office. The work machine monitors its position using an onboard GPS system and compares its actual speed and position to the site map. If the work machine exceeds the speed restriction, the work machine receives a signal and reduces speed.
