Information Flow Definitions

rail crossing control data  (Planned)  Selected Comm Solution

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

rail crossing request  (Planned)  Selected Comm Solution

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

rail crossing status  (Planned)  Selected Comm Solution

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

signal control commands  (Planned)  Selected Comm Solution

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

signal control device configuration  (Planned)  Selected Comm Solution

Data used to configure traffic signal control equipment including local controllers and system masters.

signal control plans  (Planned)  Selected Comm Solution

Traffic signal timing parameters including minimum green time and interval durations for basic operation and cycle length, splits, offset, phase sequence, etc. for coordinated systems.

signal control status  (Planned)  Selected Comm Solution

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

signal fault data  (Planned)  Selected Comm Solution

Faults reported by traffic signal control equipment.

signal system configuration  (Planned)  Selected Comm Solution

Data used to configure traffic signal systems including configuring control sections and mode of operation (time based or traffic responsive).

traffic metering control  (Planned)  Selected Comm Solution

Control commands and operating parameters for ramp meters, interchange meters, mainline meters, and other systems equipment associated with roadway metering operations.

traffic metering status  (Planned)  Selected Comm Solution

Current operational status and operating parameters for ramp meters, interchange meters, mainline meters and other control equipment associated with roadway metering operations.
