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

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.
