This data flow is used to provide the operational status (state of the device, configuration, and fault data) of a set of field equipment, including sensors (e.g., traffic flow, speed, wind, chemical, temperature, precipitation) and other field devices (e.g., signals, ramp meter controllers, CCTVs, automated roadway treatment systems, barrier and safeguard systems, lighting systems) to the center. By monitoring this data flow, the receiving process can assess the health and current status of all field equipment and repair if deemed necessary. The data flow consists of the following data items each of which is defined in its own DDE:
