field_equip_maint_status

This data flow provides a report for the Manage Traffic function of the operational status (state of the device, configuration, and fault data) and repair status of all field equipment monitored by the Manage Maintenance and Construction 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, barrier, and safeguard systems). By monitoring this data flow, the receiving process can monitor the health and current status of field equipment. It consists of the following data items each of which is defined in its own DDE:

list_size{station_id
+ equip_identity
+ equip_device_status}
