Abstract
Navigational lane guidance enhances a maneuver display by incorporating full display of available lanes in a freeway, when available in the map data. An otherwise regular turn icon display is replaced with a variable width image that grows to show all available lanes, highlighting lanes usable to complete a navigated maneuver. A new lane TrueType font displays the lane guidance image, with individual characters representing each possible line situation. Since TrueType fonts are vector-based, they can be used to generate the lane images at any size, in a platform-independent fashion. The lane font has direction arrows, which can be combined to form composite arrows; and additional direction arrows as needed to allow replacement of the routing icons currently in use. Lane dividers may also be implemented.
