indicator_status_from_signals
This data flow provides the operational status (state of the device, configuration, and fault data) of an indicator used on a surface street for the Manage Traffic function. This data flow shows that an indicator has developed a fault and is therefore operating incorrectly. The fault will have been found by a process that is local to the indicator itself. The data flow consists of the following data items each of which is defined in its own DDE:
roadside_device_status
+ device_identity
+ station_id
