1. A method of determining a time to embark on an overall day'"'"'s route determined by a navigation device, comprising:
- determining said overall day'"'"'s route including each of a plurality of separate trips to different ending locations, each of said plurality of separate trips being separated in time over a day;
determining an estimated total travel time of traversal for said overall day'"'"'s route between a beginning geographic location of a first one of said plurality of separate trips, and an ending geographic location of a last one of said plurality of separate trips, based on an average of prior real time sampling of traffic patterns over an extended period of time, mapping data, and a future start time for embarking on said overall days route;
prompting a best future start time for embarking on said overall day'"'"'s route based on said average of real time sampling of traffic patterns over said extended period of time; and
re-determining said estimated total travel time of traversal for said overall day'"'"'s route, and update a map with future predictive traffic condition information, in response to said modification of said future start time.

Abstract
A navigation device includes a predictive traffic data database to store predictive traffic data at a plurality of times and a map database to store mapping data. A mapping module calculates a route and an estimated time of traversal for a route between a beginning geographic location and an ending geographic location based on the predictive traffic data and the mapping data. A start time modification module monitors for a modification of a start time for the route, with the mapping module recalculating the estimated time of traversal in response to the modification of the start time for the route.

6. A navigation device, comprising:
-
a mapping module arranged to determine an overall day'"'"'s route including each of a plurality of separate trips to different ending locations, each of said plurality of separate trips being separated in time over a day; a database to maintain said different ending locations, and to determine an estimated total travel time of traversal for said overall day'"'"'s route between a beginning geographic location of a first one of said plurality of separate trips, and an ending geographic location of a last one of said plurality of separate trips, said estimated total travel time being based on an average of prior real time sampling of traffic patterns over an extended period of time, mapping data, and a future start time to embark on said first one of said plurality of separate trips; and a graphical departure time control arranged to prompt a best future start time to embark on said first one of said plurality of separate trips based on said average of real time sampling of traffic patterns over said extended period of time; wherein said mapping module is arranged to re-determine said estimated total travel time of traversal for said overall day'"'"'s route, and update a map with future predictive traffic condition information, in response to modification of said future start time. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)

16. Apparatus for determining an estimated total travel time of traversal for an overall day'"'"'s route determined by a navigation device, comprising:
-
means for determining said overall day'"'"'s route including each of a plurality of separate trips to different ending locations, each of said plurality of separate trips being separated in time over a day; means for determining an estimated total travel time of traversal for said overall day'"'"'s route between a beginning geographic location of a first one of said plurality of separate trips, and an ending geographic location of a last one of said plurality of separate trips, based on an average of prior real time sampling of traffic patterns over an extended period of time, mapping data, and a future start time for embarking on said overall day'"'"'s route; means for prompting a best future start time for embarking on said overall day'"'"'s route based on said average of real time sampling of traffic patterns over said extended period of time; and means for re-determining said estimated total travel time of traversal for said overall day'"'"'s route, and update a map with future predictive traffic condition information, in response to said modification of said future start time. - View Dependent Claims (17, 18, 19, 20)
