System and method for dynamic navigational route selection
First Claim
1. A vehicle navigation system, said system comprising:
- a navigation route indicator for presenting to a user a travel route based upon the fastest anticipated transit time between a set of points;
a receiver for accepting data pertaining to current average speeds within an area encompassed by said set of points; and
a processor for determining a particular route having the fastest anticipated transit time from among a plurality of possible routes matching said set of points, said anticipated transit time being determined, at least in part, from said accepted data.

Abstract
A navigation system and method factors into its routing decisions information pertaining to transient delays encountered from time to time, one example of such a transient delay is accident information obtained from currently available broadcast traffic flow sources. The system can also factor in historically available traffic delay data based on time of day or other parameters. The navigation system keeps track of the routes traveled by the vehicle (or user) and the times of transit of such routes. When a user requests a route based upon given end-points, the navigation system can use its own stored historical data, as well as currently available traffic delay data, to calculate and announce a given route.

11. A method of determining the fastest anticipated transit time in a roadway navigation system;
- said method comprising;
accepting from a user at least one end-point to define a navigation route having the least transit time for said user;
factoring anticipated transit times between said end-points for each possible navigation route with historically available transit times between said end-points for each possible navigation route and with available data pertaining to currently known traffic delays between said end-points for each possible navigation route; and
based on said factoring, communicating a navigation route having the least transit time between said endpoints. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A vehicle navigation system operable for displaying a user'"'"'s current position superimposed on a graphically represented map, said system comprising:
-
means for establishing routes to be traveled by said user, said routes based on a fastest transit time between various points; and
means for adjusting said routes based upon transient data received by said navigation system from time to time. - View Dependent Claims (22, 23, 24)
