Estimation of roadway travel information based on historical travel data
First Claim
1. An automobile navigation system for specifying future travel information for travel along a desired route on a future date, the automobile navigation system comprising:
- a processor configured to estimate future travel conditions associated with the desired route on the future date and to correlate the future travel information with historical travel information to perform the estimation; and
a data storage that stores real-time travel information, the real-time time travel information being used to determine the estimated future travel conditions.

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.
