Abstract
Techniques are provided for displaying a route symbol with narrative driving directions. A route symbol for a particular maneuver may be used to represent the road to which the maneuver relates. For example, one type of a route symbol that may be used to represent a road may be an interstate route symbol that has substantially the same appearance (e.g., substantially the same or similar shape, and/or substantially the same coloration) as an interstate route sign used to mark the interstate itself. Another example of a type of a route symbol that represents a road is an highway route symbol that looks substantially the same as a highway route sign used to mark a state highway. A route symbol used for the display of a maneuver also may include route symbols that are related to the type of maneuver, such as the type of a turn, described by the maneuver.
