Information Flow Definitions

barrier system control  (Near-term)  

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  (Near-term)  

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  (Medium-term)  

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  (Medium-term)  

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.

roadway dynamic signage data  (Near-term)  

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  (Existing)  

Current operating status of dynamic message signs.

traffic images  (Near-term)  

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  (Near-term)  

Information used to configure and control video surveillance systems.

work zone warning device control  (Near-term)  

Data used to configure and control work zone safety monitoring and warning devices.

work zone warning status  (Near-term)  

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.
