Abstract

A system for navigation along a desired route on a desired future date may include a map interface operable to display a traffic condition and a travel time received via a communication network, and an automobile navigation network communicatively coupled to the communication network. The automobile navigation network may estimate the traffic condition and the travel time for travel along the desired route on the desired future date based on historical travel information, current traffic information and current weather information. Information regarding the estimated travel conditions may be automatically communicated to the map interface. The traffic condition may include geographic location information and/or route information. The historical travel information may include historical traffic information.

Claims

1-20. -20. (canceled)

21. A system for navigation along a desired route on a desired future date, the system comprising:

a map interface operable to display a traffic condition and a travel time received via a communication network; and

an automobile navigation network communicatively coupled to the communication network, the automobile navigation network estimates the traffic condition and the travel time for travel along the desired route on the desired future date based on historical travel information, current traffic information and current weather information.

22. The system of claim 21, wherein information regarding the estimated travel conditions is automatically communicated to the map interface.

23. The system of claim 21, wherein the traffic condition comprises geographic location information.

24. The system of claim 21, wherein the traffic condition comprises route information, and wherein the historical travel information comprises historical traffic information.

25. The system of claim 21, wherein the historical traffic information is associated with a day of the week the desired future date falls on.

26. The system of claim 21, wherein the communication network comprises a broadband data packet network.

27. The system of claim 21, wherein the map interface is installed in an automobile.

28. The system of claim 21, wherein the map interface is installed in a mobile device.

29. The system of claim 21, wherein the historical travel information comprises historical weather information.

30. A method for navigation along a desired route on a desired future date, the method comprising:

by a map interface communicatively coupled to an automobile navigation network via a communication network;

displaying a traffic condition and a travel time received via the communication network,

wherein the automobile navigation network estimates the traffic condition and the travel time for travel along the desired route on the desired future date based on historical travel information, current traffic information and current weather information.

31. The method of claim 30, wherein the traffic condition comprises geographic location information.

32. The method of claim 30, wherein the traffic condition comprises route information, and wherein the historical travel information comprises historical traffic information.

33. The method of claim 32, wherein the historical traffic information is associated with a day of the week the desired future date falls on.

34. The method of claim 30, wherein the communication network comprises a broadband data packet network.

35. The method of claim 30, wherein the map interface is installed in an automobile.

36. The method of claim 30, wherein the map interface is installed in a mobile device.

37. The method of claim 30, wherein the historical travel information comprises historical weather information.
