ABSTRACT:
A method and apparatus for determining an alternate route from a new source location located on an original route to a subsequent location on the original route using a vehicle navigation system are described. A portion of the original route to be avoided by the alternate route is determined which begins at the new source location. The portion of the original route includes a plurality of segments each of which has an original parameter associated therewith. Selected ones of the original parameters are adjusted thereby resulting in a plurality of adjusted parameters. The alternate route is then determined based in part on the adjusted parameters.
