Information Flow Definitions
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.
intersection status (Planned) Selected Comm Solution
Current signal phase and timing information for all lanes at a signalized intersection. This flow identifies active lanes and lanes that are being stopped and specifies the length of time that the current state will persist for each lane. It also identifies signal priority and preemption status and pedestrian crossing status information where applicable.
signal priority status (Planned) Selected Comm Solution
In response to a request for signal priority, this flow indicates the status of the priority or preemption request.
vehicle signage data (Planned) Selected Comm Solution
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., local traffic and road conditions, lane restrictions, work zones, detours, closures, advisories, and warnings).
