Information Flow Definitions
barrier system control (Planned)
Information used to configure and control barrier systems that are represented by gates, barriers and other automated or remotely controlled systems used to manage entry to roadways.
barrier system status (Planned)
Current operating status of barrier systems. Barrier systems represent gates, barriers and other automated or remotely controlled systems used to manage entry to roadways. Status of the systems includes operating condition and current operational state.
environmental sensor data (Future)
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 (Future)
Data used to configure and control environmental sensors.
field equipment status (Existing)
Reports from field equipment (sensors, signals, signs, controllers, etc.) which indicate current operational status.
infrastructure monitoring sensor control (Future)
Data used to configure and control infrastructure monitoring sensors.
infrastructure monitoring sensor data (Future)
Data read from infrastructure–based sensors that monitor the condition or integrity of transportation infrastructure including bridges, tunnels, interchanges, pavement, culverts, signs, transit rail or guideway, and other roadway infrastructure. Includes sensor data and the operational status of the sensors.
roadway advisory radio data (Planned)
Information used to initialize, configure, and control roadside highway advisory radio. 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 advisory radio status (Planned)
Current operating status of highway advisory radios.
roadway dynamic signage data (Future)
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 devices.
roadway dynamic signage status (Future)
Current operating status of dynamic message signs.
roadway treatment system control (Future)
Control data for remotely located, automated devices, that treat the road surface (e.g., de–icing applications).
roadway treatment system status (Future)
Current operational status of automated roadway treatment devices (e.g., anti–icing systems).
traffic detector control (Future)
Information used to configure and control traffic detector systems such as inductive loop detectors and machine vision sensors.
traffic detector data (Future)
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 image meta data (Planned)
Meta data that describes traffic images. Traffic images (video) are in another flow.
traffic images (Planned)
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. Meta data that describes the images is contained in another flow.
video surveillance control (Planned)
Information used to configure and control video surveillance systems.
work zone warning device control (Future)
Data used to configure and control work zone safety monitoring and warning devices.
work zone warning status (Future)
Status of a work zone safety monitoring and warning devices. This flow documents system activations and includes additional supporting information (e.g., an image) that allows verification of the alarm.
