Architecture Flow Definitions

intersection status  (Planned)  Applicable ITS Standards

Intersection status including current operational status, signal phase and timing information, intersection geometry, surface conditions, warnings of potential violations or hazardous conditions, and approaching vehicle information. This may include information about the position, velocity, acceleration, and turning status of approaching vehicles.

traffic probe data  (Planned)  Applicable ITS Standards

Vehicle data that is used to determine traffic conditions. In a basic implementation, the data could be limited to time stamped unique identifiers that can be used to measure a vehicle’s progress through the network. In more advanced implementations, the vehicle may report current position, speed, and heading and snapshots of recent events including route information, starts and stops, speed changes, and other information that can be used to estimate traffic conditions.

traffic probe reporting management  (Planned)  Applicable ITS Standards

Data used to manage probe data reporting by vehicles. This flow indicates to the vehicle when to report probe data, the type of probe data to send, and thresholds for nominal conditions when sending data can be skipped.

vehicle intersection safety data  (Planned)  Applicable ITS Standards

Vehicle path and acceleration data provided by vehicles approaching or occupying an intersection. It identifies the intersection, vehicle position and motion, the anticipated lane and movement that will be used in the intersection, and notification of potential violations or other detected safety hazards.

vehicle profile  (Planned)  Applicable ITS Standards

Information about a vehicle including vehicle type and equipment capabilities.

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, advisories, and detours).
