Architecture Flow Definitions

field device status_ud  (Planned)  

hri control data  (Existing)  Applicable ITS Standards

Data required for HRI information transmitted at railroad grade crossings and within railroad operations.

hri request  (Existing)  Applicable ITS Standards

A request for highway-rail intersection status or a specific control request intended to modify HRI operation.

hri status  (Existing)  Applicable ITS Standards

Status of the highway-rail intersection equipment including both the current state or mode of operation and the current equipment condition.

right-of-way request notification  (Existing)  Applicable ITS Standards

Notice that a request has occurred for signal prioritization, signal preemption, pedestrian call, multi-modal crossing activation, or other source for right-of-way.

signal control commands  (Existing)  Applicable ITS Standards

Control of traffic signal controllers or field masters including clock synchronization.

signal control status  (Existing)  Applicable ITS Standards

Operational and status data of traffic signal control equipment including operating condition and current indications.

signal fault data  (Existing)  Applicable ITS Standards

Faults from traffic signal control equipment.

traffic flow  (Existing)  Applicable ITS Standards

Raw and/or processed traffic detector data which allows derivation of traffic flow variables (e.g., speed, volume, and density measures) and associated information (e.g., congestion, potential incidents). This flow includes the traffic data and the operational status of the traffic detectors.

traffic sensor control  (Existing)  Applicable ITS Standards

Information used to configure and control traffic sensor systems.
