Architecture Flow Definitions

barrier system control  (Planned)  Applicable ITS Standards

Information used to configure and control barrier systems that are represented by gates, barriers and other automated or remotely controlled systems used to manage entry to roadways.

barrier system status  (Planned)  Applicable ITS Standards

Current operating status of barrier systems. Barrier systems represent gates, barriers and other automated or remotely controlled systems used to manage entry to roadways. Status of the systems includes operating condition and current operational state.

field device status  (Planned)  Applicable ITS Standards

Reports from field equipment (sensors, signals, signs, controllers, etc.) which indicate current operational status.

hri control data  (Planned)  Applicable ITS Standards

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

hri request  (Planned)  Applicable ITS Standards

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

hri status  (Planned)  Applicable ITS Standards

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

infrastructure monitoring sensor control  (Planned)  Applicable ITS Standards

Data used to configure and control infrastructure monitoring sensors.

infrastructure monitoring sensor data  (Planned)  Applicable ITS Standards

Data read from infrastructure-based sensors that monitor the condition or integrity of transportation infrastructure including bridges, tunnels, interchanges, pavement, culverts, signs, transit rail or guideway, and other roadway infrastructure. Includes sensor data and the operational status of the sensors.

reversible lane control  (Planned)  Applicable ITS Standards

Control of automated reversible lane configuration and driver information systems.

reversible lane status  (Planned)  Applicable ITS Standards

Current reversible lane status including traffic sensor and surveillance data and the operational status and mode of the reversible lane control equipment.

right-of-way request notification  (Planned)  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.

roadway information system data  (Existing)  Applicable ITS Standards

Information used to initialize, configure, and control roadside systems that provide driver information (e.g., dynamic message signs, highway advisory radio, beacon systems). This flow can provide message content and delivery attributes, local message store maintenance requests, control mode commands, status queries, and all other commands and associated parameters that support remote management of these systems.

roadway information system status  (Existing)  Applicable ITS Standards

Current operating status of dynamic message signs, highway advisory radios, beacon systems, or other configurable field equipment that provides dynamic information to the driver.

roadway treatment system control  (Planned)  Applicable ITS Standards

Control data for remotely located, automated devices, that affect the roadway surface (e.g. de-icing applications).

roadway treatment system status  (Planned)  Applicable ITS Standards

Current operational status of automated roadway treatment devices (e.g., anti-icing systems).

safeguard system control  (Planned)  Applicable ITS Standards

Data that controls safeguard systems (remotely controlled equipment used to mitigate the impact of incidents on transportation infrastructure, such as blast shields, exhaust systems, etc.).

safeguard system status  (Planned)  Applicable ITS Standards

Current operating status of safeguard systems (remotely controlled equipment used to mitigate the impact of incidents on transportation infrastructure, such as blast shields, exhaust systems, etc.). Status of the systems includes operating condition and current operational state.

signal control commands  (Planned)  Applicable ITS Standards

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

signal control device configuration  (Planned)  Applicable ITS Standards

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

signal control plans  (Planned)  Applicable ITS Standards

signal control status  (Planned)  Applicable ITS Standards

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

signal fault data  (Planned)  Applicable ITS Standards

Faults from traffic signal control equipment.

signal system configuration  (Planned)  Applicable ITS Standards

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

traffic metering control  (Planned)  Applicable ITS Standards

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)  Applicable ITS Standards

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

variable speed limit control  (Planned)  Applicable ITS Standards

Information used to configure and control variable speed limit systems including the equipment used to provide current speed limits and other information to drivers and the equipment used to monitor traffic and environmental conditions along the roadway.

variable speed limit status  (Planned)  Applicable ITS Standards

Current operating status of the variable speed limit systems including the state of the equipment.
