Connected Vehicle Roadside Equipment --> Light Vehicle OBE:
local traveler information
Definitions
local traveler information (Information Flow): Traveler information including traffic, road, and weather conditions for a particular locality. This flow includes the location-specific traveler information and time effectivity of the information.
Connected Vehicle Roadside Equipment (Source Physical Object): 'Connected Vehicle Roadside Equipment' (CV RSE) represents the Connected Vehicle roadside devices (i.e., Roadside Units (RSUs)) equipped with short range wireless (SRW) communications technology, as well as any other supporting equipment that leverage the RSU and are not described by other objects (e.g., a local roadside processor). CVRSE are used to send messages to, and receive messages from, nearby vehicles and personal devices equipped with compatible communications technology. 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.
Light Vehicle OBE (Destination 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.

| Basis | This data is intentionally transmitted to everyone via a broadcast. It can also be determined via other visual indicators. | Some minimal guarantee of data integrity is necessary for all C-ITS flows. Flaws in this information will have a minimal effect on systems receiving it. All of the information can be verified through other means, and in a worst case scenario will only cause slightly increased traffic in the general proximity of the RSE. DISC: Original V2I analysis classified this as LOW. | All of the information provided through this flow will be available from other sources and no systems will directly rely upon it. | |
