Information Flow Definitions
field equipment status (Existing) Selected Comm Solution
Reports from field equipment (sensors, signals, signs, controllers, etc.) which indicate current operational status.
roadway dynamic signage data (Existing) Selected Comm Solution
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 treatment system control (Future) Selected Comm Solution
Control data for remotely located, automated devices, that treat the road surface (e.g., de–icing applications).
roadway treatment system status (Future) Selected Comm Solution
Current operational status of automated roadway treatment devices (e.g., anti–icing systems).
traffic detector data (Future) Selected Comm Solution
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 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) Selected Comm Solution
Information used to configure and control video surveillance systems.
work zone warning device control (Future) Selected Comm Solution
Data used to configure and control work zone safety monitoring and warning devices.
work zone warning status (Future) Selected Comm Solution
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.
