Abstract
An autonomous vehicle identifies an intersection, identifies an object in proximity to the intersection, identifies a plurality of outlets of the intersection, and, for each outlet, identifies a polyline associated with the outlet, identifies a target point along the polyline, and determines a constant curvature path from the object to the target point. The system determines a score associated with each outlet based at least in part on the constant curvature path of the outlet, generates a pruned set of outlets that includes one or more of the outlets from the plurality of outlets based on its score, and for each outlet in the pruned set, generates a reference path from the object to the target point of the outlet.
