Abstract:
1. A method in a computing device for generating a graphical turn indicator to illustrate a maneuver at a road junction that interconnects a plurality of road segments including a first road segment and a second road segment, the method comprising: determining, based on the geometry of the road junction, in which circular sector each of the plurality of road segments lies to generate a mapping between the plurality of road segments and a multiplicity of circular sectors, wherein each of the multiplicity of circular sectors corresponds to a different turn type; in response to determining that the first road segment and the second road segment are mapped to a shared circular sector, associating the first road segment with a circular sector adjacent to the shared circular sector to generate an adjusted mapping between the plurality of road segments and the multiplicity of circular sectors; and generating the graphical turn indicator according to the adjusted mapping, including generating different graphical elements for different turn types indicated by the graphical turn indicator.
