Abstract

Systems and methods for estimation of roadway travel information based on historical travel data are disclosed. In one embodiment, a system for estimating travel conditions may comprise, for example, a communication network; an automobile navigation system communicatively coupled to the communication network, the automobile navigation system for specifying a future travel information for travel along the desired route on the desired date; and a processor communicatively coupled to the communication network, the processor estimating travel conditions associated with the desired route on the desired date, and the processor performing said estimation by correlating the future travel information with historical travel information.

Claims

1. A system that estimates travel conditions along a desired route on a desired future date, the system comprising:

a communication network;

an automobile navigation system communicatively coupled to the communication network, the automobile navigation system specifies future travel information for travel along the desired route on the desired future date; and

a processor communicatively coupled to the communication network, the processor estimating travel conditions associated with the desired route on the desired future date, and the processor performing said estimation by correlating the future travel information for the desired future date with historical travel information, and wherein said correlating is further based on at least a correlation of current traffic information and current weather information.

2. The system of claim 1, wherein information regarding the estimated travel conditions is automatically communicated to the automobile navigation system.

3. The system of claim 1, wherein the future travel information comprises geographic location information.

4. The system of claim 1, wherein the future travel information comprises route information, and wherein the historical travel information comprises historical traffic information.

5. The system of claim 1, wherein the communication network comprises a broadband data packet network.

6. The system of claim 1, wherein the automobile navigation system is installed in an automobile.

7. The system of claim 1, wherein the automobile navigation system is installed in a mobile device.

8. The system of claim 1, wherein the historical travel information comprises historical weather information.

9. A method for estimating travel conditions along a desired route on a desired future date, the method comprising:

in an automobile navigation system communicatively coupled to a communication network;

specifying future travel information for travel along the desired route on the desired future date; and

receiving estimated travel conditions associated with the desired route on the desired future date, wherein the travel conditions are estimated by correlating the future travel information for the desired future date with historical travel information, and wherein said correlating is further based on at least a correlation of current traffic information and current weather information.

10. The method of claim 9, wherein the future travel information comprises geographic location information.

11. The method of claim 9, wherein the future travel information comprises route information, and wherein the historical travel information comprises historical traffic information.

12. The method of claim 9, wherein the communication network comprises a broadband data packet network.

13. The method of claim 9, wherein the automobile navigation system is installed in an automobile.

14. The method of claim 9, wherein the automobile navigation system is installed in a mobile device.

15. The method of claim 9, wherein the historical travel information comprises historical weather information.
