Architecture Flow Definitions
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.
lane management control (Planned) Applicable ITS Standards
Information used to configure and control dynamic lane management systems.
lane management information (Planned) Applicable ITS Standards
System status of managed lanes including current operational state, violations, and logged information. This includes lane usage information including both traditional traffic flow measures and special information associated with managed lanes such as measured passenger occupancies. It also includes the operational status of the lane management equipment.
roadway dynamic signage data (Planned) Applicable ITS Standards
Information used to initialize, configure, and control dynamic message signs. 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 dynamic signage status (Planned) Applicable ITS Standards
Current operating status of dynamic message signs, highway advisory radios, or other configurable field equipment that provides dynamic information to the driver.
shoulder management control (Planned) 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 (Planned) Applicable ITS Standards
System status including current operational state, violations and logged information.
speed monitoring control (Planned) Applicable ITS Standards
Information used to configure and control automated speed monitoring, speed warning, and speed enforcement systems.
speed monitoring information (Planned) Applicable ITS Standards
System status including current operational state and logged information including measured speeds, warning messages displayed, and violation records.
stop sign gap assist control (Planned) Applicable ITS Standards
Configuration and control of detectors that monitor traffic on the major road and signs that provide stop sign gap assist alerts and warnings to vehicles on the minor road.
stop sign gap assist status (Planned) Applicable ITS Standards
The current operational state and status of the field controller, sensors, and signs that support the stop sign gap assist application.
traffic detector control (Existing) Applicable ITS Standards
Information used to configure and control traffic detector systems such as inductive loop detectors and machine vision sensors.
traffic detector data (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 sensor system.
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. This flow includes the images and meta data that describes the images.
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.
video surveillance control (Planned) Applicable ITS Standards
Information used to configure and control video surveillance systems.
