Maneuver generation program and method

摘要

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. A maneuver type is associated with a location if data corresponding to the location pass all the tests in the set of tests that characterize the maneuver type. The maneuver type associated with the location is used in providing a maneuvering instruction related to the location to the user by the navigation application.
