Connected Vehicle Roadside Equipment --> Personal:
intersection geometry
Definitions
intersection geometry (Information Flow): The physical geometry of an intersection covering the location and width of each approaching lane, egress lane, and valid paths between approaches and egresses. This flow also defines the location of stop lines, cross walks, specific traffic law restrictions for the intersection (e.g., turning movement restrictions), and other elements that support calculation of a safe and legal vehicle path through the intersection.
Connected Vehicle Roadside Equipment (Source 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.
Personal (Destination Physical Object): The 'Personal' physical object is used to model core capabilities that are common to more than one physical object in the 'Personal' class. It provides the general executive, management, and utility functions that may be shared by different types of personal devices.

Basis | Map data intended for general use by any C-ITS component than needs it. No information here includes PII or anything else that, if viewed by someone other than the participant, would lead to harm. | Map data is used for a host of application purposes. This widespread use means that any corruption in the data has a widespread and far reaching effect. | Occasional outages of this flow will delay updates and lead to a loss of accurate function of some applications. Depending on the application this could be HIGH. |
