Architecture Flow Definitions

automated roadway control data  (Future)  

Control commands and operating parameters provided to field equipment that controls and monitors automated vehicle operations.

automated roadway status  (Future)  

Current operational status of an automated vehicle operations facility, including the status of the field equipment and vehicles using the facility.

barrier system control  (Future)  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  (Future)  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.

environmental sensor data  (Planned)  Applicable ITS Standards

Current road conditions (e.g., surface temperature, subsurface temperature, moisture, icing, treatment status) and surface weather conditions (e.g., air temperature, wind speed, precipitation, visibility) as measured and reported by fixed and/or mobile environmental sensors. Operational status of the sensors is also included.

environmental sensors control  (Planned)  Applicable ITS Standards

Data used to configure and control environmental sensors.

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.

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.

road user protection data  (Future)  Applicable ITS Standards

Current data as well as operational status from mixed roadway and right-of-way systems.

road user protection device control  (Future)  Applicable ITS Standards

Control requests and operating parameters for mixed roadway and right-of-way systems.

roadway information system data  (Planned)  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  (Planned)  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 warning system control  (Future)  Applicable ITS Standards

Information used to configure and control roadway warning systems.

roadway warning system status  (Future)  Applicable ITS Standards

Current operating status of roadway warning systems.

short range communications status  (Future)  

Status of the short range communications equipment including the current state or mode of operation and the current equipment status.

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

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)  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).

speed monitoring control  (Future)  Applicable ITS Standards

Information used to configure and control automated speed monitoring, speed warning, and speed enforcement systems.

speed monitoring information  (Future)  Applicable ITS Standards

System status including current operational state and logged information including measured speeds, warning messages displayed, and violation records.

traffic flow  (Planned)  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 images  (Planned)  Applicable ITS Standards

High fidelity, real-time traffic images suitable for surveillance monitoring by the operator or for use in machine vision applications.

traffic metering control  (Future)  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  (Future)  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.

traffic probe data  (Future)  Applicable ITS Standards

Vehicle data that is used to determine traffic conditions. In a basic implementation, the data could be limited to time stamped unique identifiers that can be used to measure a vehicle’s progress through the network. In more advanced implementations, the vehicle may report current position, speed, and heading and snapshots of recent events including route information, starts and stops, speed changes, and other information that can be used to estimate traffic conditions.

traffic sensor control  (Planned)  Applicable ITS Standards

Information used to configure and control traffic sensor systems.

vehicle signage data  (Future)  Applicable ITS Standards

In-vehicle signing data that augments regulatory, warning, and informational road signs and signals. The information provided would include static sign information (e.g., stop, curve warning, guide signs, service signs, and directional signs) and dynamic information (e.g., current signal states, grade crossing information, local traffic and road conditions, advisories, and detours).
