Abstract: A system comprises a fleet of autonomous vehicles, a terminal, and an autonomous freight network (AFN) management device. The AFN management device receives information indicating that an autonomous vehicle is inbound to the terminal. The AFN management device determines locations of objects within the terminal based on sensor data. The AFN management device determines landing instructions indicating to avoid the locations of objects detected from the sensor data. The AFN management device communicates the landing instructions to the autonomous vehicle. A control device associated with the autonomous vehicle determines a route to reach a landing pad within the terminal based on the landing instructions. The control device instructs the autonomous vehicle to travel along the route.

Abstract: Techniques for analysis of autonomous vehicle operations are described. As an example, a method of autonomous vehicle operation includes storing sensor data from one or more sensors located on the autonomous vehicle into a storage medium, performing, based on at least some of the sensor data, a simulated execution of one or more programs associated with the operations of the autonomous vehicle, generating, based on the simulated execution of the one or more programs and as part of a simulation, one or more control signal values that control a simulated driving behavior of a simulated vehicle, and providing a visual feedback of the simulated driving behavior of the simulated vehicle on a simulated road.

Abstract: A system comprises an autonomous vehicle (AV) and a control device operably coupled with the AV. The control device detects a series of events within a threshold period of time, where a number of series of events in the series of events is above a threshold number. The series of events taken in the aggregate within the threshold period of time deviates from a normalcy mode. The normalcy mode comprises events that are expected to the encountered by the AV. The control device determines whether the series of events corresponds to a malicious event, where the malicious event indicates tampering with the AV. In response to determining that the series of events corresponds to the malicious event, the series of events are escalated to be addressed.

Abstract: Each of a plurality of landing pads is sized and shaped to accommodate an AV. Landing pad sensor(s) are located in or around each landing pad. A control subsystem receives landing pad sensor data from the one or more landing pad sensors and receives, from a first AV traveling to a location of the plurality of landing pads, a request for an assigned landing pad in which the first AV should park. In response to this request, the control subsystem determines, based on the received landing pad sensor data, whether a first landing pad is free of obstructions that would prevent receipt of the first AV. If the first landing pad is free of obstructions, an indication is provided to the AV that the first landing pad is the assigned landing pad.
