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.
