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.

Multi-Access Edge Computing (Source Physical Object): 'Multi-Access Edge Computing' ((MEC) previously known as mobile edge computing) represents computing devices that operate and are managed like a cloud server, but are deployed at the edge of a network (typically a cellular network, but it could be any network). While not in strict proximity to the transportation network, these systems do benefit from vastly decreased distances to the roadway compared to central systems, and so can provide lower latency than strictly backoffice systems

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.

US: SAE Other J2735 - Secure Wireless Internet (ITS) (12)
EU: Signal Control Messages - Secure Wireless Internet (EU) (16)

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 Lane-Level Mapping - Secure Wireless Internet (ITS)

Solution Description

This solution is used within Canada and the U.S.. It combines standards associated with US: SAE Lane-Level Mapping with those for I-M: Secure Wireless Internet (ITS). The US: SAE Lane-Level Mapping standards include upper-layer standards required to implement lane-level and road furniture mapping information flows. The I-M: Secure Wireless Internet (ITS) standards include lower-layer standards that support secure communications between two entities, either or both of which may be mobile devices, but they must be stationary or only moving within wireless range of a single wireless access point (e.g., a parked car). Security is based on X.509 or IEEE 1609.2 certificates. A non-mobile (if any) endpoint may connect to the service provider using any Internet connection method.

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.
