The operator attributes can be used to facilitate enhanced remote operations for autonomous vehicles. For example, request parameters can be obtained in response to a request for remote assistance associated with an autonomous vehicle. An operator can be selected to assist with autonomy tasks for the autonomous vehicle based at least in part on the operator attributes for the operator and the request parameters associated with the request. Remote assistance for the first autonomous vehicle can be initiated, facilitated by the first operator in response to the request for remote assistance.
Various examples are directed to systems and methods for controlling an autonomous vehicle. For example, a navigator system at an autonomous vehicle may generate a plurality of local routes beginning at a vehicle location and extending to a plurality of local route end points. The navigator system may access general route cost data, the general route cost data describing general route costs from the plurality of local route end points to a trip end point. The navigator system may select the first local route of the plurality of routes based at least in part on the general route cost data. A vehicle autonomy system at the autonomous vehicle may begin to control the autonomous vehicle along the first local route.
Aspects of the present disclosure include systems, methods, and devices to facilitate pick-up/drop-off zone (PDZ) handoffs between autonomous vehicles. Consistent with some embodiments, a pick-up/drop-off zone (PDZ) is located based on detecting a first autonomous vehicle stopped at a stopping location. A system determines, based on one or more criteria, whether to request the first autonomous vehicle to remain stopped at the stopping location to create an opportunity for a second autonomous vehicle to claim the PDZ. An amount of time for the first autonomous vehicle to remain stopped at the stopping location is determined based on the one or more criteria. A request to remain stopped at the stopping location is transmitted to a vehicle autonomy system of the first autonomous vehicle based on satisfaction of the one or more criteria. The request specifies the amount of time for the first autonomous vehicle to remain at the stopping location.
The present disclosure is directed to systems and methods associated with a communication infrastructure. The communication infrastructure includes a vehicle integration platform that includes a plurality of application programming interfaces configured to facilitate message communication among clients. The communication infrastructure includes a registration authority system configured to receive certificate signing requests from the clients and to generate client-specific credentials for establishing a predetermined time period of ability for client authentication within the vehicle integration platform. The communication infrastructure includes a certificate authority system configured to normalize requests received from the clients via the registration authority system such that the client-specific credentials are established according to an approved hierarchy of licensing certificates. The communication infrastructure includes a security library accessible by each of the clients and by components of the vehicle integration platform. The security library is configured to provide implementation logic for signing messages and implementation logic for validating messages.

Disclosed are autonomous vehicles that may autonomously navigate at least a portion of a route defined by a service request allocator. The autonomous vehicle may, at a certain portion of the route, request remote assistance. In response to the request, an operator may provide input to a console that indicates control positions for one or more vehicle controls such as steering position, brake position, and/or accelerator position. A command is sent to the autonomous vehicle indicating how the vehicle should proceed along the route. When the vehicle reaches a location where remote assistance is no longer required, the autonomous vehicle is released from manual control and may then continue executing the route under autonomous control.

Various examples are directed to systems and methods for routing an autonomous vehicle. For example, a system may access temporal data comprising a first temporal data item. The first temporal data item may describe a first roadway condition, a first time, and a first location. The system may also access a routing graph that comprises a plurality of route components and determine that a first route component of the routing graph corresponds to the first location.

The dispatch system may determine a first routing constraint for autonomous vehicles of the first vehicle type using the trip result data and select an autonomous vehicle to execute a first new trip using the first routing constraint. The dispatch system may send a request to execute the first new trip to the selected autonomous vehicle.

A network computing system can coordinate on-demand transport serviced by transport providers operating throughout a transport service region. The transport providers can comprise a set of internal autonomous vehicles (AVs) and a set of third-party AVs. The system can receive a transport request from a requesting user of the transport service region, where the transport request indicates a pick-up location and a destination. The system can determine a subset of the transport providers to service the respective transport request, and executing a selection process among the subset of the transport providers to select a transport provider to service the transport request. The system may then transmit a transport assignment to the selected transport provider to cause the selected transport provider to service the transport request.
