barrier_system_status_for_detours

This data flow is used within the Manage Traffic 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 gates 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}

Sub Data Flows

• device_identity
• list_size
• roadside_device_status
