1. A method for determining a preferred route using a computer-implemented routing system, the method comprising:
- using a routing system to access an origin and a destination in a routing graph representing a network of roads and including two or more nodes and one or more links, each link representing a road and each node representing an intersection that includes at least one road;
using the routing system to determine a preferred route from the origin to the destination based at least in part upon a variable cost for traversing at least one link in the routing graph, the variable cost being based on a day in which the at least one link is to be traversed; and
communicating the preferred route from the routing system to a user system.

Abstract
A preferred route may be determined from an origin location to a destination location. The determination is made by processing directed links (e.g., one-way edges) in a graph that includes one or more links and two or more nodes. The determination of a preferred route may include an estimate of the time required at one or more intersections along alternative routes and/or an estimate of the time required to travel the alternative routes based on the day of the week or the day of the year in which travel occurs.

15. A computer-readable medium or propagated signal having embodied thereon a computer program configured to determine a preferred route using a computer-implemented routing system, the medium or signal comprising one or more code segments configured to:
-
use a routing system to access an origin and a destination in a routing graph representing a network of roads and including two or more nodes and one or more links, each link representing a road and each node representing an intersection that includes at least one road;
use the routing system to determine a preferred route from the origin to the destination based at least in part upon a variable cost for traversing at least one link in the routing graph, the variable cost being based on a day in which the at least one link is to be traversed; and
communicate the preferred route from the routing system to a user system. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
