Abstract

A method of operating a navigation system to provide route guidance messages for traveling along a route is disclosed. A plurality of features visible from segments of the route are obtained from a geographic database associated with the navigation system. An importance rating is determined for each identified feature. The guidance message references the identified feature with the highest determined importance rating. Importance ratings take into account the persistence or seasonal dependence of the identified characteristics. The importance rating is adjusted in favor of the identified feature that is closest to the lane in which the vehicle is currently located.

Description

[0001] References to related applications [0002] This application is a partial continuation application of application No. 12 / 549,604 filed on August 28, 2009. Technical field [0003] The present invention relates to a method and a system for operating a navigation system, and more particularly to a method and method for using contextual elements along a calculated route from a starting location to a destination location to provide route guidance (guidance) and system Background technique [0004] A navigation system that provides various navigation-related functions and features to end users is available. For example, some navigation systems can determine the optimal route to travel from a starting point to a destination location along the road network in a geographic area. Using input from the end user, the navigation system can check various potential routes between the starting location and the destination location to determine the optimal route. The navigation system can ...
