1. A method of processing vehicle navigation information for use in autonomous vehicle navigation, the method comprising: receiving, by a server, navigation information from a plurality of vehicles, wherein the navigation information from the plurality of vehicles is associated with a common road segment; storing, by the server, the navigation information associated with the common road segment; generating, by the server, at least a portion of an autonomous vehicle road navigation model for the common road segment, wherein the autonomous vehicle road navigation model includes a three-dimensional spline corresponding to a target trajectory along the common road segment; and distributing, by the server, the autonomous vehicle road navigation model to one or more autonomous vehicles for use in autonomously navigating the one or more autonomous vehicles along the common road segment.
