Information Flow Definitions

barrier system status  (Future)  

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 control  (Future)  

Data used to configure and control environmental sensors.

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.

roadway warning system control  (Future)  

Information used to configure and control roadway warning systems.

roadway warning system status  (Future)  

Current operating status of roadway warning 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  (Future)  

Meta data that describes traffic images. Traffic images (video) are in another flow.

traffic images  (Future)  

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  (Future)  

Information used to configure and control video surveillance systems.
