Map Update System --> 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.
Map Update System (Source Physical Object): The 'Map Update System' represents a provider of map databases used to support ITS services. It supports the provision of the map data that are used directly by vehicles (e.g., roadway and intersection geometry data sets), travelers (e.g., navigable maps used for route guidance and display maps used at traveler information points), system operators (e.g., map data used by Traffic Operators to monitor and manage the road network, and map data used by Fleet Managers to manage a vehicle fleet). It may represent a third-party provider or an internal organization that produces map data for agency use. In the latter case, the 'Map Update System' is typically included as part of the center (e.g., a Traffic Management Center) of the infrastructure owner/operator that manages map data. Products may include simple display maps, map data sets that define detailed road network topology and geometry, or full geographic information system databases that are used to support planning and operations.
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. |
