Abstract: A vehicle includes a wireless transceiver configured to communicate with an infrastructure device in a vehicle-to-everything (V2X) channel having a predetermined channel frequency, the V2X channel being divided into a plurality of subchannels; and a controller, configured to responsive to the wireless transceiver detecting a wireless signal within the frequency of the V2X channel, measure a power spectral density (PSD) gradient of the wireless signal across at least two subchannels of the V2X channel, and compare a magnitude of the PSD gradient against a predetermined gradient threshold, and responsive to verifying the magnitude of the PSD gradient of the wireless signal is greater than the gradient threshold, identify there is an interference to the V2X channel.

Abstract: An enforcement vehicle receives vehicle broadcasts from motorist vehicles, including vehicle identification information. The enforcement vehicle presents the identification information in a selectable manner on a display and receives selection of one of the motorist vehicles. The enforcement vehicle sends a communication request to the selected motorist vehicle and receives confirmation from the motorist vehicle, resulting in an open communication channel. Further, enforcement vehicle receives identification of information to be provided from the motorist vehicle and sends an information request for the identified information. Responsive to receiving a response to the information request, the enforcement vehicle, or a process associated therewith, determines whether information included in the response indicates compliance with a predefined requirement, and, responsive to non-compliance, alerts an occupant of the enforcement vehicle of the existence of and at least one characteristic of the non-compliance.

Abstract: A system includes a processor and a memory. The memory stores instructions executable by the processor to receive an image from a stationary camera. The memory stores instructions to determine location coordinates of an object identified in the image based on location coordinates specified for the image. The memory stores instructions to operate a vehicle based on the object location coordinates.

Abstract: A toll advertisement message (TAM) broadcast from a roadside unit (RSU) is received by a vehicle via V2X communication, the TAM indicating geographic locations of lanes of a roadway for which tolls are due and cost information for traversing the lanes of the roadway. A heading of the vehicle is determined in relation to a TAM reference point indicating a geographic location of a toll gantry. A toll zone boundary region for the vehicle is identified by filtering the geographic locations of the lanes in the TAM to include only those lanes in a travel direction consistent with the heading. A lane straddling algorithm is utilized to identify, for each of the lanes in the travel direction, a respective percentage within each lane that the vehicle is traveling. A tolling usage message (TUM) is sent via the V2X communication, indicating to the RSU the percentage lane usage of the vehicle.

Abstract: A toll advertisement message (TAM) broadcast from a roadside unit of a roadway is received. The TAM may include a public key of a toll charger cloud. Responsive to receipt of the TAM, a tolling usage message (TUM) is sent. The TUM may include information encrypted with a public key of a toll service provider, information encrypted with the public key of the toll charger cloud, and a public key of the telematics control unit. Responsive to broadcast of the TUM, a toll usage message acknowledgement (TUM-ACK message. A toll receipt message (TRM) is also received. The TRM is encrypted with the public key of the telematics control unit. The TRM is decrypted using a private key of the telematics control unit corresponding to the public key of the telematics control unit.

Abstract: A request is received, from an onboard unit of a vehicle to a roadside unit in control of a gate protecting a gated area, for access rights to the gated area. Responsive to determining that the vehicle is authorized to enter, vehicle localization is performed to confirm that the vehicle has an unobstructed path to the gate. The vehicle localization is performed using one or more approaches. Responsive to confirming that the vehicle has an unobstructed path to the gate, direct the gate to open to allow the vehicle to proceed.
