For obtaining more realistic junction shapes in a road network map, a classifier (212) obtains crosswalk features from an aerial image (208, 308) of a road and an authoritative road network map (210, 310) of the road. An enhanced road network map (320) is created by co-locating the crosswalk features as crosswalk instances (312) into the authoritative road network map. Each crosswalk instance in the enhanced road network map includes coordinates of a boundary (316) of a single crosswalk. The crosswalk instances of the enhanced road network map are grouped into one or more junction instances by a geometrical reasoner, and their coordinates are refined based on coordinate centers of the junctions. Road network nodes, road network segments and attributes of the enhanced road network map are then updated to provide its connectivity. Afterwards, the enhanced road network map can be converted into a pre-defined format for road traffic simulations.

In various examples, one or more deep neural networks (DNNs) are executed to regress on control points of a curve, and the control points may be used to perform a curve fitting operation—e.g., Bezier curve fitting—to identify landmark locations and geometries in an environment.

As a result, reconstructed curves corresponding to the landmarks—e.g., lane line, road boundary line, crosswalk, pole, text, etc.—may be used by a vehicle to perform one or more operations for navigating an environment.
