Light Vehicle OBE --> Connected Vehicle Roadside Equipment:
vehicle location and motion for surveillance

Definitions

vehicle location and motion for surveillance (Information Flow): Data describing the vehicle's location in three dimensions, heading, speed, acceleration, braking status, and size. This flow represents monitoring of basic safety data ('vehicle location and motion') broadcast by passing connected vehicles for use in vehicle detection and traffic monitoring applications.

Light Vehicle OBE (Source Physical Object): The 'Light Vehicle OBE' includes traveler-oriented capabilities that apply to passenger cars, trucks, and motorcycles that are used for personal travel. The rules vary by jurisdiction, but generally light vehicles are restricted in their weight and the maximum number of passengers they can carry. In ARC-IT, the Light Vehicle OBE represents vehicles that are operated as personal vehicles that are not part of a vehicle fleet and are not used commercially; thus, the choice between the various vehicle subsystems should be based more on how the vehicle is used than how much the vehicle weighs. See also the 'Vehicle' subsystem that includes the general safety and information services that apply to all types of vehicles, including light vehicles.

Connected Vehicle Roadside Equipment (Destination Physical Object): 'Connected Vehicle Roadside Equipment' (CV RSE) represents the Connected Vehicle roadside devices that are used to send messages to, and receive messages from, nearby vehicles using Dedicated Short Range Communications (DSRC) or other alternative wireless communications technologies. Communications with adjacent field equipment and back office centers that monitor and control the RSE are also supported. This device operates from a fixed position and may be permanently deployed or a portable device that is located temporarily in the vicinity of a traffic incident, road construction, or a special event. It includes a processor, data storage, and communications capabilities that support secure communications with passing vehicles, other field equipment, and centers.

Communication Solutions

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.
