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.

intersection status  (Planned)  Applicable ITS Standards

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.

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.

personal crossing safety information  (Planned)  Applicable ITS Standards

Current crossing status including permission to cross, crossing time remaining, and warnings in the event that a vehicle reports an imminent intersection infringement that may impact non–motorized users including pedestrians and cyclists.

personal location  (Planned)  Applicable ITS Standards

The current location (latitude, longitude, and elevation) reported by the personal information device

personal signal service request  (Planned)  Applicable ITS Standards

A request for right of way from a personal device that indicates the type of traveler (pedestrian, special needs pedestrian, bicyclist, etc.), anticipated time of arrival, travel path, and crossing duration.
