Architecture Flow Definitions

automated roadway control data  (Long-term)  

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

automated roadway status  (Long-term)  

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

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  (Existing)  Applicable ITS Standards

Data used to configure and control environmental sensors.

hov data  (Existing)  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.

lane management control  (Existing)  Applicable ITS Standards

Information used to configure and control dynamic lane management systems.

lane management information  (Existing)  Applicable ITS Standards

System status including current operational state, violations, and logged information.

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.

shoulder management control  (Long-term)  Applicable ITS Standards

Information used to configure and control systems that allow use of a shoulder as a lane for vehicular traffic.

shoulder management information  (Long-term)  Applicable ITS Standards

System status including current operational state, violations and logged information.

signal control commands  (Existing)  Applicable ITS Standards

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

signal control device configuration  (Existing)  Applicable ITS Standards

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

signal control plans  (Existing)  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  (Existing)  Applicable ITS Standards

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

signal fault data  (Existing)  Applicable ITS Standards

Faults from traffic signal control equipment.

signal system configuration  (Existing)  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  (Existing)  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  (Existing)  Applicable ITS Standards

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