Position Corrections Source --> Connected Vehicle Roadside Equipment:
position corrections

Definitions

position corrections (Information Flow): Ground based reference station positioning corrections

Position Corrections Source (Source Physical Object): The 'Position Corrections Source' represents the external source of land-based position corrections that augment satellite-provided (e.g., GPS) positioning data.

Connected Vehicle Roadside Equipment (Destination 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.

Interoperability Description
Local In cases where an interface is normally encapsulated by a single stakeholder, interoperability is still desirable, but the motive is vendor independence and the efficiencies and choices that an open standards-based interface provides.

Rating Not Applicable High High
Basis This data is intentionally transmitted to everyone via a broadcast. It can also be determined via other visual indicators. An incorrect location corrections message, could lead to a false warning or lack of warning. A lack of warning can have obvious catastrophic consequences, while a false warning could lead to users ignoring warnings due to perceived inaccuracy. Given that this triple may apply to highly dynamic environments (such as work zones), its accuracy is paramount, and thus if sent, must have HIGH integrity. If locations corrections are not delivered, catastrophic consequences could result from incorrect locations data on the device that should have received the corrections. DISC: HIGH is a tall barrier for this flow.
