摘要： The subject disclosure relates to solutions for arbitrating traffic blockages along vehicle routes. In some aspects, the disclosed technology encompasses a method including steps for determining a vehicle route, wherein the vehicle route comprises at least one lane plan to be followed by an autonomous vehicle (AV), identifying a blockage along the vehicle route, analyzing the blockage to determine if the blockage constitutes a persistent blockage, and if the blockage constitutes a persistent blockage, associating a time value with the blockage. Systems and machine-readable media are also provided.

摘要： Various technologies described herein pertain to routing an autonomous vehicle based upon risk of takeover of the autonomous vehicle by a human operator. A computing system receives an origin location and a destination location of the autonomous vehicle. The computing system identifies a route for the autonomous vehicle to follow from the origin location to the destination location based upon output of a computer-implemented model. The computer-implemented model is generated based upon labeled data indicative of instances in which autonomous vehicles are observed to transition from operating autonomously to operating based upon conduction by human operators while the autonomous vehicles are executing predefined maneuvers. The computer-implemented model takes, as input, an indication of a maneuver in the predefined maneuvers that is performed by the autonomous vehicle when the autonomous vehicle follows a candidate route. The autonomous vehicle then follows the route from the origin location to the destination location.

摘要： The subject disclosure relates to techniques for real-time lane validation. A process of the disclosed technologies can include steps for receiving a route from a remote computing system, the route indicating lanes on the route that an autonomous vehicle must traverse, traversing at least one lane of the lanes on the route, and sending sensor data to the remote computing system after traversing the at least one lane, the sensor data indicating whether the at least one lane is in accordance with a virtual lane of a virtual map, the virtual lane corresponding to the at least one lane.

摘要： Systems, methods, and devices are disclosed for synchronizing map updates for a navigating autonomous vehicle. A management service on a managing node can receive an update to a portion of a first map, where a limited visibility map, which is a subset of the first map, can be determined based on a geographical area around an autonomous vehicle navigating a route. The limited visibility map can be synchronized among all the nodes while the autonomous vehicle is using the limited visibility map by the management service delivering, to a plurality of downstream nodes, the update to the limited visibility map when the update does not modify a portion of the limited visibility map, and by bypassing, to the plurality of downstream nodes, the update to the limited visibility map when the update modifies a portion of the limited visibility map.

摘要： For one embodiment of the present disclosure, systems and methods for dynamically responding to detected changes in a semantic map of an autonomous vehicle (AV) are described. A computer implemented method includes obtaining sensor signals from a sensor system of the AV to monitor driving operations, processing the sensor signals for sensor observations of the sensor system, determining whether a map change exists between the sensor observations and a prerecorded semantic map, determining whether the map change is located in a planned route of the AV when the map change exists, and generating a first scenario with a first priority level to to stop the AV at a safe location based on a location of the map change.

摘要： A computing system that analyzes the network effects of avoidance areas on autonomous vehicle routing is described herein. The computing system includes a data store that comprises a set of avoidance areas through which the autonomous vehicle is prohibited from being routed. A routing system generates an initial route from a source location to a target location irrespective of avoidance areas included on the initial route. When a number of avoidance areas on the initial route exceed a predetermined threshold, one or more alternative routes are generated from the source location to the target location that respectively circumvent a corresponding identified avoidance area on the initial route. Metrics are evaluated for the one or more alternative routes and a subset of avoidance areas are outputted to desirably be removed from the set of avoidance areas.
