Abstract: A vehicle navigation system may include a data pipeline that proposes routing graph modifications from automatically ingested data sources and that provides enough context to suggest an expiration time to remove the routing graph modifications once imposed. The system and method receives from at least one data source routing graph modification data including geographic location data identifying a location to which a routing graph modification applies. The routing graph modification data is associated with one or more roadway elements in a routing graph of a navigation constraints system, and the routing graph modification data associated with the one or more roadway elements is classified as a routing graph modification. The routing graph modification is added to or, if expired, removed from the navigation constraints system.

Abstract: Systems and methods for determining object motion and controlling autonomous vehicles are provided. In one example embodiment, a computing system can be configured to perform operations. The operations can include obtaining data indicative of state(s) of a first object and a second object within a surrounding environment of an autonomous vehicle. The operations can include determining a first predicted motion trajectory of the first object based at least in part on the state data. The operations can include determining a second predicted motion trajectory of the second object based at least in part on the state data and the first predicted motion trajectory of the first object. The operations can include determining a motion plan for the autonomous vehicle based at least in part on the second predicted motion trajectory of the second object and initiating a motion control in accordance with at least a portion of the motion plan.
