Abstract
A method for operating a navigation system is disclosed. An ordered plurality of interconnected segments providing a route from an origin to a destination is obtained. A guidance message for each of the segments is formed. The step of forming the guidance message comprises determining whether to reference a previous segment and adding a reference to a current segment.

A method of providing route guidance for traveling from a first segment to a second segment using a geographic database comprising:
- obtaining data from said geographic database that indicates whether a reference to said first segment provides orientation for traveling to said second segment;
- if said data indicates said reference provides orientation, providing a phrase of after or a synonym thereof and a name of said first segment;
- providing an indication of travel direction to said second segment;
- and
- providing a reference to said second segment.
A method of providing route guidance for traveling from a first segment to a second segment using a geographic database comprising:
- obtaining data from said geographic database that indicates whether to reference a node connecting said first segment to said second segment to provide orientation for traveling to said second segment;
- if said data indicates to reference said node, providing a phrase of at or a synonym thereof and a name of said node;
- providing an indication of travel direction to said second segment;
- and
- providing a reference to said second segment.
A method of providing route guidance for traveling on a first segment using a geographic database comprising:
- obtaining data from said geographic database that indicates whether to reference a next node to provide orientation for traveling on said first segment, wherein said next node connects said first segment to a next segment;
- if said data indicates to provide said reference, providing a phrase of toward or a synonym thereof and a name of said next node;
- and
- providing a reference to said first segment.
A method of providing route guidance for traveling from a first segment to a second segment comprising:
- providing a phrase of after or a synonym thereof;
- providing a name of said first segment;
- providing an indication of a travel direction from said first segment to said second segment;
- and
- providing a name of said second segment, wherein said name of said second segment is a name of a geographic feature visible from a junction of said first segment and said second segment.
