This data flow provides the 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:

+ device_identity
+ station_id
