barrier_system_status_to_emerg

This data flow is sent from the Manage Traffic function to the Manage Emergency Services function to report to another process the operational status of a barrier system, such as gates, barriers, and other automated or remotely controlled systems used to manage entry to roadways. By monitoring this data flow and thereby knowing which systems have been activated, the receiving process can better coordinate an emergency response. 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}
