This data flow is sent from the Manage Emergency Services function to the Manage Traffic function to report to another process the operational status of a safeguard system (equipment used to mitigate the impact of incidents on transportation infrastructure, such as blast shields, exhaust systems, etc.). By monitoring this data flow and thereby knowing which systems have been activated, the receiving process can better coordinate traffic detours. It consists of the following data items each of which is defined in its own DDE:

list_size + list_size{station_id
+ device_identity
+ roadside_device_status}
