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.
passive vehicle monitoring control (Planned) Applicable ITS Standards
Control commands used to control detection systems that rely on infrastructure-based identification of individual vehicles to measure travel times and other related measures by identifying the same vehicle at different points in the network. Related technologies include bluetooth readers and license plate recognition systems.
passive vehicle monitoring data (Planned) Applicable ITS Standards
Time stamped identifiers that identify the vehicles that have passed through a detection zone.
rail crossing control data (Planned) Applicable ITS Standards
Data required for HRI information transmitted at railroad grade crossings and within railroad operations.
rail crossing 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.
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 (Planned) Applicable ITS Standards
Information used to configure and control traffic detector systems such as inductive loop detectors and machine vision sensors.
traffic detector data (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 sensor system.
