indicator_status_for_roads_from_center

This data flow provides the operational status (state of the device, configuration, and fault data) of indicators 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 not local to the indicator itself, and may be located anywhere in the geographic area covered by the function. The data flow consists of the following data items each of which is defined in its own DDE:

list_size{roadside_device_status
+ device_identity
+ station_id}
