Information Flow Definitions

environmental sensor data  (Existing)  Selected Comm Solution

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.

field equipment status  (Existing)  Selected Comm Solution

Reports from field equipment (sensors, signals, signs, controllers, etc.) which indicate current operational status.

roadside archive data  (Existing)  Selected Comm Solution

A broad set of data derived from roadside sensors that includes current traffic conditions, environmental conditions, and any other data that can be directly collected by roadside sensors. This data also indicates the status of the sensors and reports of any identified sensor faults.

roadway dynamic signage status  (Existing)  Selected Comm Solution

Current operating status of dynamic message signs.

traffic images  (Existing)  

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.

work zone warning status  (Existing)  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.
