Embodiment Construction

[0024] I. Navigation system

[0025] figure 1 Is a block diagram of a navigation system 100 associated with a computing platform 102, such as an in-vehicle navigation device, a personal navigation device, a mobile computer, a mobile phone, a personal digital assistant (PDA), a personal computer, or any other computer. Navigation system 100 is a combination of hardware and software components. In one embodiment, the navigation system 100 includes a processor 104, a drive 106 coupled to the processor 104, and a non-volatile memory storage device 108 for storing a navigation application software program 110 and possibly other information.

[0026] The navigation system 100 also includes a positioning system 112 . Positioning system 112 may utilize GPS-type technology, a dead reckoning-type system, or a combination of these or other systems, all of which are known in the art. Positioning system 112 may include suitable sensing devices to measure distance traveled, speed, direc...

Abstract

A method of operating a navigation system to provide a route guidance message for traveling a route is disclosed. A plurality of features visible from a road segment of the route is obtained from a geographic database associated with the navigation system. An importance rating for each of the identified features is determined. The guidance message references the identified feature having a highest determined importance rating. The importance rating considers a permanence or a seasonal dependency of the identified feature. The importance rating is adjusted to favor the identified feature closest to the lane in which the vehicle is currently located.

Description

[0001] References to related applications [0002] This application is a continuation-in-part of Application Serial No. 12 / 549,604, filed August 28,2009. technical field [0003] The present invention relates to methods and systems for operating a navigation system, and more particularly to methods and systems for providing route guidance using contextual elements along a calculated route from an origin location to a destination location. system Background technique [0004] Navigation systems are available that provide various navigation-related functions and features to end users. For example, some navigation systems are capable of determining the optimal route to travel along a road network in a geographic area from an origin location to a destination location. Using input from the end user, the navigation system can examine various potential routes between the origin location and the destination location to determine the optimal route. The navigation system may then p...
