Abstract
A method of and apparatus for generating an alternate route for a system to travel to a predetermined destination are described. The method comprises determining a velocity of a system traveling along a primary route; and generating an alternate route to the primary route if the system velocity is below a predetermined motion threshold. A navigation system for generating an alternate route to a destination includes a motion sensor for detecting the navigation system velocity along a primary route and a controller coupled with the motion sensor. The controller receives a motion signal indicating navigation system motion and generates an alternate route to the primary route responsive to the motion signal indicating navigation system motion different from a predetermined motion threshold value.
