摘要： The present disclosure relates to generating graphical turn indicators associated with road junctions having an on-route road segment and multiple off-route road segments extending from a center of the road junction. More particularly, the present disclosure provides graphical turn indicators that represent road junctions having multiple road segments that extend from a center of the road junction within close angular proximity with respect to one another. Each road segment of a road junction is mapped to a unique graphical element of the graphical turn indicator and each graphical element represents a particular turn type.
