Architecture Flow Definitions
automated roadway control data (Planned)
Control commands and operating parameters provided to field equipment that controls and monitors automated vehicle operations.
automated roadway status (Planned)
Current operational status of an automated vehicle operations facility, including the status of the field equipment and vehicles using the facility.
emissions sensor control (Existing) Applicable ITS Standards
Data used to configure and control vehicle emissions sensors.
environmental sensor data (Existing) 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.
hov data (Planned) Applicable ITS Standards
Current HOV lane information including both standard traffic flow measures and information regarding vehicle occupancy in HOV lanes, and operational status of the HOV monitoring equipment.
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.
intersection blockage notification (Planned) Applicable ITS Standards
Notification that a highway-rail intersection is obstructed and supporting information.
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.
roadside archive data (Planned) Applicable ITS Standards
A broad set of data derived from roadside sensors that includes current traffic conditions, environmental conditions, and any other data that can be directly collected by roadside sensors. This data also indicates the status of the sensors and reports of any identified sensor faults.
roadway equipment coordination (Planned) Applicable ITS Standards
The direct flow of information between field equipment. This includes transfer of information between sensors and driver information systems (e.g., DMS, HAR, variable speed limit signs, dynamic lane signs) or control devices (e.g., traffic signals, ramp meters), direct coordination between adjacent control devices, interfaces between detection and warning or alarm systems, and any other direct communications between field equipment.
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.
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).
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 (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.
traffic probe data (Planned) 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 emissions data (Existing) Applicable ITS Standards
Measured emissions of specific vehicles comprised of exhaust pollutants including hydrocarbons, carbon monoxide, and nitrogen oxides.
video surveillance control (Planned) Applicable ITS Standards
Information used to configure and control video surveillance systems.
