Commercial Vehicles to Regional Airport/Port Authority Connected Vehicle Roadside Equipment Interface Diagram

Architecture Flow Definitions

intersection geometry  (Planned)  Applicable ITS Standards

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.

ITS information  (Planned)  

Information exchanged by ITS systems or devices. This flow is a super–flow; it does not define specific content since it represents any information flow exchange between physical objects defined in ARC–IT. This information flow represents any of those information flows and inherits the data content and attributes defined in the more detailed information flows.

local traveler information  (Planned)  Applicable ITS Standards

Traveler information including traffic, road, and weather conditions for a particular locality. This flow includes the location–specific traveler information and time effectivity of the information.

location correction  (Planned)  Applicable ITS Standards

Information provided to improve positional accuracy. These corrections allow a mobile GPS receiver, such as a GPS system in a connected vehicle, to achieve a
greater absolute positional accuracy, compensating for errors that exist in satellite positioning.

map updates  (Planned)  Applicable ITS Standards

Map update which could include a new underlying static or real–time map or map layer(s) update.

parking availability  (Planned)  Applicable ITS Standards

Information on available parking. This flow identifies available spaces with associated information about parking restrictions and location for each available space.

parking facility geometry  (Planned)  Applicable ITS Standards

Precise spatial description of a parking facility that locates each parking space and the ingress and egress routes that are used to travel to and from the spaces.

roadway geometry  (Planned)  Applicable ITS Standards

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.

service advertisement  (Planned)  Applicable ITS Standards

An advertisement of available services and identification of how those services may be accessed (e.g., RF parameters, identifiers, etc.). Services include network services such as IPv6 routing, public roadside services such as intersection safety, back office services including situation data services and security credentials, or private services.

vehicle location and motion for surveillance  (Planned)  Applicable ITS Standards

Data describing the vehicle's position, heading, speed, acceleration, transmission, steering wheel angle, braking status, size information, and trajectory. 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.

vehicle signage data  (Planned)  Applicable ITS Standards

In–vehicle signing data that augments regulatory, warning, and informational road signs and signals. The information provided would include static sign information (e.g., stop, curve warning, guide signs, service signs, and directional signs) and dynamic information (e.g., current signal states, grade crossing information, local traffic and road conditions, detours, advisories, and warnings).
