Definitions

vehicle path prediction (Information Flow): The predicted future vehicle path of travel. This flow includes an indication of the future positions of the transmitting vehicle that can be used by receiving vehicles to support coordinated driving maneuvers and enhance in-lane and out-of-lane threat classification.

Vehicle (Source Physical Object): This 'Vehicle' physical object is used to model core capabilities that are common to more than one type of Vehicle. It provides the vehicle-based general sensory, processing, storage, and communications functions that support efficient, safe, and convenient travel. Many of these capabilities (e.g., see the Vehicle Safety service packages) apply to all vehicle types including personal vehicles, commercial vehicles, emergency vehicles, transit vehicles, and maintenance vehicles. From this perspective, the Vehicle includes the common interfaces and functions that apply to all motorized vehicles. The radio(s) supporting V2V and V2I communications are a key component of the Vehicle. Both one-way and two-way communications options support a spectrum of information services from basic broadcast to advanced personalized information services. Advanced sensors, processors, enhanced driver interfaces, and actuators complement the driver information services so that, in addition to making informed mode and route selections, the driver travels these routes in a safer and more consistent manner. This physical object supports all six levels of driving automation as defined in SAE J3016. Initial collision avoidance functions provide 'vigilant co-pilot' driver warning capabilities. More advanced functions assume limited control of the vehicle to maintain lane position and safe headways. In the most advanced implementations, this Physical Object supports full automation of all aspects of the driving task, aided by communications with other vehicles in the vicinity and in coordination with supporting infrastructure subsystems.

Other Vehicles (Destination Physical Object): 'Other Vehicle OBEs' represents other connected vehicles that are communicating with the host vehicle. This includes all connected motorized vehicles including passenger cars, trucks, and motorcycles and specialty vehicles (e.g., maintenance vehicles, transit vehicles) that also include the basic 'Vehicle OBE' functionality that supports V2V communications. This object provides a source and destination for information transfers between connected vehicles. The host vehicle on-board equipment, represented by the Vehicle OBE physical object, sends information to, and receives information from the Other Vehicle OBEs to model all connected vehicle V2V communications in ARC-IT.

US: SAE LTE-V2X BSM - LTE-V2X WSMP (16)
US: SAE Basic Safety Messages - WAVE WSMP (18)

Solutions are sorted in ascending Gap Severity order. The Gap Severity is the parenthetical number at the end of the solution.

Selected Solution

US: SAE LTE-V2X BSM - LTE-V2X WSMP

Solution Description

This solution is used within the U.S.. It combines standards associated with US: SAE LTE-V2X BSM with those for V-X: LTE-V2X WSMP. The US: SAE LTE-V2X BSM standards include upper-layer standards required to implement V2V safety information flows over C-V2X. The V-X: LTE-V2X WSMP standards include lower-layer standards that support connectionless, near constant, ultra-low latency vehicle-to-any communications using the WAVE Short Messaging Protocol (WSMP) over 3GPP C-V2X in the 5.9GHz spectrum.

Note that some layers might have alternatives, in which case all of the gap icons associated with every alternative may be shown on the diagram, but the solution severity calculations (and resulting ordering of solutions) includes only the issues associated with the default (i.e., best, least severe) alternative.

Basis	This data is intentionally transmitted to other vehicles operating in a cluster.	Vehicle path data is critical to the performance of a group of vehicles in a vehicle cluster scenario. Incorrect data here could trigger a severe accident scenario.	Some vehicle cluster scenarios cannot function without this flow. Worst case is that some vehicles will drop from the platoon however, which while significant to mobility does not have a direct severe consequence.
