Map Update System to Vehicle OBE: intersection geometry
Flow Description
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.

Solutions
 Solution Description
This solution is used within the U.S.. It combines standards associated with US: SAE Signal Control Messages with those for I-M: Mobile Internet (US). The US: SAE Signal Control Messages standards include upper-layer standards required to implement signal control information flows. The I-M: Mobile Internet (US) standards include lower-layer standards that support secure communications between two entities, either or both of which may be actively moving; based on X.509 or IEEE 1609.2 certificates. A non-mobile (if any) endpoint may connect to the wide-area-wireless service provider using any Intneret connection method.
