Abstract: A method for deploying of a backup roadside unit (RSU) vehicle to provide on-demand RSU services is described. The method may include determining, by a server, a resource specification to deploy a selected backup RSU vehicle to a requested site. The determining of the resource specification may be performed by the server in response to a scene description received from a requestor. The method also includes sending a dispatch instruction to the selected backup RSU vehicle to deploy the selected backup RSU vehicle to the requested site. In this method, a hardware/software capability of the selected backup RSU vehicle is matched to the resource specification determined by the server.

Abstract: In an example, a method captures, at a first connected vehicle situated in a travel path segment, first sensor data describing an environment proximate to the first connected vehicle. The environment includes a first unconnected vehicle. The method wirelessly receives, via a communication network at the first connected vehicle from a second connected vehicle situated in the travel path segment, second sensor data describing one or more operating characteristics of the first unconnected vehicle. The method estimates, using the first sensor data and the second sensor data, a vehicle action of the first unconnected vehicle.

Abstract: In an example, a method receives vehicle data for a plurality of vehicles associated with a geographic region. The method determines, based on the vehicle data, a connected vehicle status of the geographic region. The connected vehicle status reflects an estimated number of connected vehicles in the geographic region at a point in time. The method determines, based on the estimated number of connected vehicles, one or more vehicle functions to be deployed by a server associated with the geographic region. The method deploys, by the server, the one or more vehicle functions.

Abstract: A method of improving efficiency of a vehicle behavior controller using a traffic state estimation network is described. The method includes feeding an input of a feature extraction network of the vehicle behavior controller with a sequence of images. The sequence of images include a highway section and corresponding traffic data. The method also includes disentangling an estimated behavior of a controlled ego vehicle. by the traffic state estimation network. The traffic state estimate network disentangles the estimated of the controlled ego vehicle from extracted traffic state features of the input provided by the feature extraction network. The method further includes selecting an action to adjust an autonomous behavior of the controlled ego vehicle according to the estimated behavior of the controlled ego vehicle.

Abstract: A system for managing vehicles includes a plurality of first level managers, and a plurality of second level managers each being in a higher hierarchical level than the plurality of first level managers and managing a section. Each of the plurality of first level managers collects data using one or more sensors of a vehicle, abstracts the data to obtain first information, and transmits a first instruction to the vehicle based on the first information. One of the plurality of second level managers receives the first information from one or more of the plurality of first level managers in the section managed by the one of the plurality of second level managers, obtains second information based on the first information, and transmits a second instruction to the vehicle based on the second information. The first instruction is different from the second instruction.
