Information Flow Definitions
access permission (Planned) Selected Comm Solution
Information returned indicating whether permission for access is granted and instructions for proceeding.
access request (Planned) Selected Comm Solution
Request for access to an access–controlled transportation facility.
intersection geometry (Planned) Selected Comm Solution
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 updates (Planned) Selected Comm Solution
Map update that could include a new underlying static or real–time map or map layer(s) update. Map layers can include highways, major roads, streets, public transport routes, pedestrian routes, topography, points of interest, and regulatory information including turn restrictions and speed limits.
road closure information (Planned) Selected Comm Solution
Road closure information provided to passing vehicles. This flow provides information about the road closure with diversion information.
roadway geometry (Planned) Selected Comm Solution
The physical geometry of a road segment that specifies the location and width of each lane, including normal lanes as well as special lanes for pedestrians and bicycles, transit vehicles, and trains. This flow also may include the curvature, grade, and superelevation or banking of the road segment.
vehicle location and motion for surveillance (Planned) Selected Comm Solution
Data describing the vehicle's location in three dimensions, heading, speed, acceleration, braking status, and size. This flow represents monitoring of basic safety data ('vehicle location and motion') broadcast by passing connected vehicles for use in vehicle detection and traffic monitoring applications.
