Abstract
A geographic database used by a navigation system includes data regarding which corners of an intersection are connected by a crosswalk and the type of crosswalk. The geographic database also includes data regarding locations of crosswalks at a location other than an intersection. Using this information, the navigation system can provide crosswalk information to a pedestrian regarding where to cross a road.
