Architecture Flow Definitions
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.
device control request (Planned) Applicable ITS Standards
Request for device control action
device data (Planned) Applicable ITS Standards
Data from detectors, environmental sensor stations, and traffic control devices including device inventory information.
device status (Planned) Applicable ITS Standards
Status information from devices
emergency traffic coordination (Planned) Applicable ITS Standards
Coordination supporting disaster response including evacuation and reentry. Includes coordination of special traffic control strategies that support efficient evacuation and reentry while protecting and optimizing movement of response vehicles and other resources responding to the emergency.
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 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.
incident information (Planned) Applicable ITS Standards
Notification of existence of incident and expected severity, location, time and nature of incident. As additional information is gathered and the incident evolves, updated incident information is provided. Incidents include any event that impacts transportation system operation ranging from routine incidents (e.g., disabled vehicle at the side of the road) through large-scale natural or human-caused disasters that involve loss of life, injuries, extensive property damage, and multi-jurisdictional response. This also includes special events, closures, and other planned events that may impact the transportation system.
intersection blockage notification (Planned) Applicable ITS Standards
Notification that a highway-rail intersection is obstructed and supporting information.
logged vehicle routes (Planned) Applicable ITS Standards
Anticipated route information for guided vehicles, special vehicles (e.g., oversize vehicles) or groups of vehicles (e.g., governor's motorcade) that may require changes in traffic control strategy.
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.
road network conditions (Planned) Applicable ITS Standards
Current and forecasted traffic information, road and weather conditions, and other road network status. Either raw data, processed data, or some combination of both may be provided by this architecture flow. Information on diversions and alternate routes, closures, and special traffic restrictions (lane/shoulder use, weight restrictions, width restrictions, HOV requirements) in effect is included along with a definition of the links, nodes, and routes that make up the road network.
road network traffic probe data (Planned) Applicable ITS Standards
Aggregated route usage, travel times, and other aggregated data collected from probe vehicles that can be used to estimate current traffic conditions.
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)
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.
