Information Flow Definitions
intersection control status (Existing) Selected Comm Solution
Status data provided by the traffic signal controller including phase information, alarm status, and priority/preempt status.
local priority request coordination (Existing) Selected Comm Solution
The direct flow of information between field equipment. This includes notification of crossing calls from pedestrians and other vulnerable road users and requests for signal prioritization or preemption, and any other request for right–of–way at an intersection. The status of the priority request is also shared. For vulnerable road users, this includes information provided to guide and warn vulnerable road users at crossings including crossing permission status and crossing time remaining.
signal control coordination (Existing) Selected Comm Solution
The direct flow of information between field equipment. This includes configuration and control of traffic signal controllers or field masters. Configuration data and operational status of traffic signal control equipment including operating condition and current indications are returned.
signal preemption request (Existing) Selected Comm Solution
Direct request for preemption to a traffic signal controller that results in preemption of the current control plan and grants right–of–way to the requesting vehicle. This flow identifies the required phase and timing of the preemption. This flow may also cancel the preemption request (e.g., when the requesting vehicle clears the intersection).
