field_equipment_status_from_traffic

This data flow provides a report for the Manage Maintenance and Construction function of the operational status (state of the device, configuration, and fault data) of all field equipment monitored or controlled by the Manage Traffic function. Field equipment includes sensors (e.g., traffic flow, speed, wind, chemical, temperature, precipitation) or other field device (e.g., signals, ramp meter controllers, CCTVs, traffic probe equipment, in-vehicle signing equipment, automated roadway treatment systems, barriers, safeguard systems, and lighting systems). By monitoring this data flow, the receiving process can monitor the health and current status of field equipment. The receiving process will use this data to arrange for repair if deemed necessary. It consists of the following data items each of which is defined in its own DDE:

list_size + list_size{station_id
+ equip_identity
+ equip_device_status}

Sub Data Flows
