Abstract

A method of operation of an intelligent real-time distributed traffic sampling and navigation system includes: receiving navigation information of a client; analyzing the navigation information to provide traffic information; generating a travel route based on the analyzing the navigation information; and sending the travel route for display on the client.

Claims

1. A method for operating an intelligent real-time distributed traffic sampling and navigation system comprising:

selecting a geographic region;

receiving a client'"'"'s navigation information from the geographic region including receiving the client'"'"'s navigation information sampled in a no server access region after a client'"'"'s position has reached an area with server access;

analyzing the client'"'"'s navigation information to provide traffic information;

generating a travel route based on the analyzing the navigation information; and

sending the travel route for displaying on a client; and

wherein receiving the client'"'"'s navigation information includes;

receiving the client'"'"'s navigation information from a portion of a client distribution.

2. The method as claimed in claim 1 further comprising:

generating a travel time based on the analyzing the navigation information; and

sending the travel time to the client'"'"'s position.

3. The method as claimed in claim 1 wherein analyzing the client'"'"'s navigation information sampled in the no server access region includes extrapolating a traffic condition in the no server access region utilizing the client'"'"'s navigation information sampled in a region having server access.

4. The method as claimed in claim 1 wherein analyzing the client'"'"'s navigation information includes corroborating the client'"'"'s navigation information with a traffic feed.

5. A method for operating an intelligent real-time distributed traffic sampling and navigation system comprising:

providing controls for selecting a geographic region at a client with the controls at the client;

receiving client'"'"'s navigation information in the geographic region including receiving the client'"'"'s navigation information sampled in a no server access region after a client'"'"'s position has reached an area with server access;

analyzing the client'"'"'s navigation information to provide traffic information;

generating a travel route based on the analyzing the client'"'"'s navigation information; and

sending the update for displaying on the client; and

wherein receiving the client'"'"'s navigation information includes;

receiving the client'"'"'s navigation information from a portion of a client distribution.

6. The method as claimed in claim 5 wherein analyzing the client'"'"'s navigation information includes processing traffic flow and displaying results of the traffic flow processing.

7. The method as claimed in claim 6 wherein analyzing the client'"'"'s navigation information includes extrapolating a traffic condition with navigation information from the no server access region to improve extrapolation analysis.

8. The method as claimed in claim 5 wherein receiving the client'"'"'s navigation information includes receiving the client'"'"'s navigation information sampled in the no server access region with navigation information sampled in an area with server access.

9. The method as claimed in claim 5 wherein analyzing the client'"'"'s navigation information includes analyzing the client'"'"'s navigation information using a best fit approach.

10. An intelligent real-time distributed traffic sampling and navigation system comprising:

a control module for selecting a geographic region;

a server receive module for receiving client'"'"'s navigation information from the geographic region including receiving the client'"'"'s navigation information sampled in a no server access region after a client'"'"'s position has reached an area with server access;

a traffic flow processing module, coupled to the server receive module, for analyzing the client'"'"'s navigation information;

a traffic flow display module, coupled to the traffic flow processing module, for displaying the output of the analyzing the client'"'"'s navigation information;

a route engine module, coupled to the traffic flow processing module, for generating a travel route based on the analyzing the client'"'"'s navigation information; and

a traffic to client module, coupled to the route engine module, for sending the travel route to the client; and

wherein receiving the client'"'"'s navigation information includes;

receiving the client'"'"'s navigation information from a portion of a client distribution.

11. The system as claimed in claim 10 further comprising:

the route engine module for generating a travel time based on the analyzing the client'"'"'s navigation information; and

the traffic to client module for sending the travel time to the client.

12. The system as claimed in claim 10 wherein the traffic flow processing module is for extrapolating a traffic condition in the no server access region utilizing the client'"'"'s navigation information sampled in a region having server access.

13. The system as claimed in claim 10 wherein the traffic flow processing module is for corroborating the client'"'"'s navigation information with a traffic feed.

14. The system as claimed in claim 10 further comprising a server client partition module for providing controls to the client.

15. The system as claimed in claim 14 wherein the traffic flow processing module is for processing traffic flow and displaying results of the traffic flow processing.

16. The system as claimed in claim 14 wherein the traffic flow processing module is for extrapolating a traffic condition with the client'"'"'s navigation information from the no server access region to improve extrapolation analysis.

17. The system as claimed in claim 14 wherein a server receive module is for receiving the client'"'"'s navigation information sampled in the no server access region with the client'"'"'s navigation information sampled in an area with server access.

18. The system as claimed in claim 14 wherein a traffic flow processing module is for analyzing the client'"'"'s navigation information using a best fit approach.
