exist in the area due to the data in memory 13. The
navigation computer then proceeds to calculate an
optimum road path route between the start position
of the vehicle and the desired destination. This
road path route is optimized based on either a
minimum time or minimum distance criterion which
criterion is preprogrammed into the navigation
computer 11. In addition, the route selected by the
computer 11 will also take into account any trip
preferences and detours which are stored in the trip
memory 12 [column 3, lines 39 through 52].
As for the additional navigation route calculations, "[t]he
trip memory 12 also includes storage locations 23 and 24 in
which additional detour or preference information will be
stored that will be used in calculating a second and third
route,
respectively" (column 4, lines 32 through 36). Kirson teaches
that
the navigation apparatus 10 will display to the
vehicle operator each of the calculated routes along
with preferably both the mileage associated with
each route and the travel time associated with each
route. Thus the vehicle operator will now have a
visual display of each of the three different routes
along with ranking criteria describing the mileage
and travel time differences between the routes.
Then the vehicle operator can select which of the
three calculated routes he desires with regard to
implementing vehicle guidance instructions for the
vehicle operator so as to arrive at the desired
destination [column 5, lines 28 through 39].
