User interface for predictive traffic
View Patent ↗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 re-calculating the estimated time of traversal in response to the modification of the start time for the route.
1. 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, based on an average of real time sampling of traffic patterns over an extended period of time, mapping data, and a future start time for traversing said overall day's route;
a graphical departure time control arranged to modify said future start time for said overall day's route; and
a display arranged to prompt a best time to depart on said overall day's route 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 viewing area with future predictive traffic condition information, in response to movement of said graphical departure time control.
