Onboard vehicle software that performs the following operations: (i) receiving, by a control device installed with a vehicle, situation assessment information pertaining to vehicle traffic; (ii) determining, by the control device, whether the situation assessment information is indicative of an event likely to impact vehicle traffic; and (iii) in response to determining that the situation assessment information is indicative of the event likely to impact vehicle traffic, sending, by the control device, a print command to a printer communicatively coupled to the control device, the printer adapted to print a patterned layer of a coloring substance to a surface supporting the vehicle, and the print command instructing the printer to print the coloring substance to the surface in a pattern encoding a notification.

Mobile wireless terminals, such as vehicles in traffic, can determine the relative positions of other vehicles with improved precision by arranging to acquire GNSS (global navigational satellite system) signals simultaneously, and then analyzing the various data sets differentially. Simultaneous acquisition can cancel many important errors such as motional errors of the vehicles, atmospheric distortions, and satellite timebase errors. Differential analysis to determine the relative positions of vehicles (as opposed to their overall geographical coordinates) can reduce errors related to satellite ephemeris and velocity, as well as roundoff errors. Localization with a precision of less than 1 meter can greatly improve collision avoidance while discriminating near-miss scenarios from imminent collisions, according to some embodiments. Messaging examples, in 5G and 6G, to manage the simultaneous acquisition and differential analysis, are provided in examples. Many other aspects are disclosed.

A method for operating a vehicle, the vehicle receiving a digital map of a parking lot and at least one target position on the parking lot via a communication network, the vehicle navigating autonomously in the parking lot to the target position on the basis of the digital map, and the vehicle autonomously parking at the target position. A device for operating a vehicle, a vehicle, a server and a computer program are also described.

A server may determine that two-way communication to a plurality of autonomous vehicles has been lost, during conditions suitable for using the autonomous vehicles for evacuation. The server may also determine evacuation points and determine a geographic perimeter around each evacuation point, the perimeter projected to encompass sufficient vehicles to service the evacuation point based on determined evacuation needs of a given evacuation point. Further, the server may formulate an evacuation instruction for each evacuation point, each instruction having one or more parameters, including at least the geographic perimeter corresponding to a given evacuation point, wherein a given evacuation instruction instructs vehicles executing the instruction to travel to the corresponding evacuation point. The server additionally may instruct broadcast of one or more of the evacuation instructions from an ATSC transmitter known to cover a geographic region including at least a portion of the geographic perimeter of each evacuation instruction transmitted.

Disclosed are an emergency vehicle supporting device and system using a drone that resolve forward traffic congestion on a road on which an emergency vehicle is driving via the drone and supports securing of a driving path for the emergency vehicle. According to the present invention, an emergency vehicle supporting device mounted on the emergency vehicle generates drone control information and transmits the generated drone control information to the drone. Further, the drone flies according to the drone control information and a location change of the emergency vehicle and broadcasts an avoidance warning to surrounding vehicles around the flying drone, so that the surrounding vehicles may help the emergency vehicle secure a driving path and thus the emergency vehicle may arrive at a destination within a desired time.

Techniques described herein improve direct communication channel reliability in a vehicle-to-everything (V2X) communication. The techniques include a (wireless communication) device that uses a first licensed band to perform a cellular network communication through a first interface (e.g., Uu), and further uses a shared spectrum to perform a V2X communication through a direct communication channel interface. The device then monitors and compares a bandwidth requirement of the V2X communication with a bandwidth of the shared spectrum. In response to the bandwidth that is less than the bandwidth requirement, the device selects a second licensed band that includes a bandwidth that is at least equal to the bandwidth requirement. Further, the selected second licensed band is different from the first licensed band to avoid channel interference. In other embodiments, the device uses the licensed band to directly establish the V2X communication.

An electronic device according to various embodiments disclosed in this document may include a first communicator supporting V2X communication, a controller, and a memory, wherein the memory stores instructions which, when executed, cause the controller to: receive at least one V2X message through the first communicator; determine whether to capture an image, based on the at least one V2X message; in response to the determination to capture the image, determine a region of interest, based on the at least one V2X message; obtain an image including the determined region of interest, through at least one imaging device electrically connected to the electronic device; identify an object included in the obtained image; match the identified object with the at least one V2X message; and generate an image with which the at least one V2X message matching the identified object is combined. Other various embodiments are possible.

A driverless traffic management vehicle has a control system having a controller interfacing steering and drive interfaces for control of respective steering and drive subsystems of the vehicle. The vehicle also has an impact attenuator and actuator therefor for configuring the attenuator in deployed and stowed configurations. The control system comprises at least one driverless mode controller operably controlling the steering and drive interfaces for controlling the vehicle in at least one of follow mode, remote-control and autonomous driverless mode of operation. To control traffic, the vehicle may be driven to a roadside location and set in the at least one driverless mode of operation to control the steering and drive interfaces accordingly.

The present invention relates to a method and an apparatus for generating a signal for low latency in a wireless communication system. The method, according to one embodiment of the present invention, for a communication device generating a situation-reporting signal for low latency and transmitting the signal to a base station in a wireless communication system comprises the steps of: generating the situation-reporting signal on the basis of a pre-set, specific situation recognized by the communication device; and transmitting the generated situation-reporting signal to the base station, wherein the situation-reporting signal may be generated so as to have a subcarrier spacing which is a pre-set number of times larger than a subcarrier spacing of a legacy communication system, the pre-set number being an integer.
