Filed:

Nov 20, 2000

Appl. No.:

9/716489

Inventors:

Michael J. O'Shea - Chicago IL

Assignee:

Navigation Technologies Corporation

International Classification:

G06F16500

US Classification:

701211

Abstract:

A maneuver generation program for a computer-based navigation system. The navigation system provides a user with a series of maneuvering instructions to go from a first location to a second location in a geographic area. The series of maneuvering instructions are derived from a list of data entities that represent a route from the first location to the second location. The list of data entities includes data that represent a plurality of locations along the route at which maneuvering instructions may be provided. The maneuver generation program determines one and preferably no more than one maneuver type selected from a predetermined plurality of maneuver types for each location of the plurality of locations along the route. The maneuver generation program performs a series of tests upon data corresponding to each location. Each of the plurality of maneuver types is characterized by a unique set of tests selected from a predetermined superset of tests.
