Map Update System to Connected Vehicle Roadside Equipment: 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 Other J2735 with those for I-F: SNMPv3. The US: SAE Other J2735 standards include upper-layer standards required to implement V2X information flows that do not yet have fully specified functionality and performance charcateristics. The I-F: SNMPv3 standards include lower-layer standards that support secure centre-to-field and field-to-field communications using simple network management protocol (SNMPv3); implementations are strongly encouraged to use the TLS for SNMP security option for this solution to ensure adeqaute security.
